- 0:32>> Welcome to Spaceime with Stuart Garry.
- 0:51A new study has found that the small
- 0:53planet that collided with the earth to
- 0:55create our moon also originated from the
- 0:57inner solar system about 4 1/2 billion
- 1:00years ago. The most momentous event in
- 1:02the history of our planet occurred. A
- 1:05huge celestial body about the size of
- 1:07the planet Mars, which astronomers have
- 1:09now named Thea, collided with a young
- 1:12proto Earth, creating a vast magma
- 1:14ocean, which eventually coalesed,
- 1:16differentiated, and then solidified to
- 1:18form the Earth as we know it today.
- 1:21Meanwhile, some of the debris ejected
- 1:23from that impact was flung up into
- 1:25orbit, eventually coalesing to form the
- 1:27moon. Exactly how that collision
- 1:29unfolded and what precisely happened
- 1:32afterwards has not been conclusively
- 1:34clarified. What is certain, however, is
- 1:36that the size, composition, and orbit of
- 1:39the Earth changed as a result, and that
- 1:41the impact marked the birth of our
- 1:43constant companion in space, the moon.
- 1:46But there are lots of questions yet to
- 1:48be answered. What kind of body was this
- 1:51Thea that so dramatically altered the
- 1:53course of our planet's development? How
- 1:55big was Thea really? We think it was
- 1:57about a third the size of the earth.
- 1:59What was it made of? And from which part
- 2:01of the solar system did it come crashing
- 2:03into the earth? The problem is finding
- 2:06answers to these questions is difficult.
- 2:08After all, Theoa was completely
- 2:10destroyed in that collision.
- 2:12Nevertheless, faint traces of it can
- 2:14still be found today in the composition
- 2:16of the Earth and Moon. Now a report in
- 2:19the journal science by researchers at
- 2:21the Maxplank Institute in the University
- 2:23of Chicago have worked out a possible
- 2:25list of ingredients that may have made
- 2:27up thea and thus helps to point us in
- 2:30the direction of its place of origin.
- 2:33You see the ratio of certain metal
- 2:34isotopes present in a body can be
- 2:36especially revealing. Isotopes are
- 2:39varants of the same element that differ
- 2:41only in the number of neutrons in their
- 2:42atomic nucleus and thus in their mass.
- 2:45In the early solar system, the isotopes
- 2:48of certain given elements were unlikely
- 2:50to be evenly distributed. At the outer
- 2:52edge of the solar system, for example,
- 2:54isotopes occurred in a slightly
- 2:56different ratio than what they did near
- 2:58the sun. So, information about the
- 3:00origin of a body's original building
- 3:02blocks is thus stored in its isotopic
- 3:04composition. To reach their conclusions
- 3:07in this study, the authors determine the
- 3:09ratio of different iron isotopes in
- 3:11Earth and moon rocks with unprecedented
- 3:13precision. They examined 15 terrestrial
- 3:16rocks and six lunar rock samples which
- 3:18were brought back by the Apollo
- 3:20missions. Earlier measurements of the
- 3:22isotope ratios of chromium, calcium,
- 3:24titanium, and zirconium had already
- 3:27shown that the Earth and Moon are
- 3:28indistinguishable in terms of their
- 3:30composition. So that clearly doesn't
- 3:32allow for any direct conclusions about
- 3:34the simply too many possible collision
- 3:37scenarios. Now most models assume that
- 3:40the moon was formed almost exclusively
- 3:42from ejected material which was flung
- 3:44off from thea but it's also possible
- 3:46that it consists primarily of material
- 3:48from the early earth's mantle or that
- 3:50the rocks from the earth and thea were
- 3:52mixed together. Now in order to learn
- 3:54more about thea the authors applied a
- 3:57kind of reverse engineering for planets
- 3:59based on the matching isotope ratios in
- 4:02today's terrestrial lunar rocks. They
- 4:04looked at which compositions and sizes
- 4:06of thea and which composition of the
- 4:08early earth could have led to the two
- 4:10bodies current compositions. In their
- 4:13investigations, the authors looked not
- 4:15only at ion isotopes but also at those
- 4:17of chromium, malebinum and sacconium.
- 4:20The different elements give access to
- 4:22different phases of planetary formation.
- 4:24Long before the devastating encounter
- 4:26with Thea, a kind of sorting process had
- 4:29already taken place inside the early
- 4:31Earth. With the formation of the
- 4:32planet's iron core, some elements such
- 4:34as iron and malebdinum accumulated
- 4:37there. So afterwards, they were largely
- 4:39absent from the rocky mantle above. The
- 4:42iron found in Earth's mantle today could
- 4:44therefore only have arrived after the
- 4:46core had formed. It may have come from
- 4:48Thea. Other elements such as zaconium,
- 4:51which didn't sink to the core, document
- 4:53the entire history of our planet's
- 4:55formation. Of the mathematically
- 4:57possible compositions of Thea and the
- 4:59early Earth that result from the
- 5:00calculations, some can be ruled out as
- 5:02implausible. While the composition of
- 5:05the early Earth can be represented
- 5:07predominantly as a mixture of known
- 5:09meteorite classes, this isn't the case
- 5:11with Thea. Different meteorite classes
- 5:14originate from different areas of the
- 5:15outer solar system. They therefore serve
- 5:18as references for the building material
- 5:20that was available during the formation
- 5:22of both the early earth and Thea. In the
- 5:25case of Thea, however, previously
- 5:27unknown material may also have been
- 5:29involved. And the authors believe that
- 5:31this material's origin lies closer to
- 5:34the sun than the orbit of the earth. The
- 5:36calculations therefore suggest that the
- 5:39itself must have originated closer to
- 5:41the sun than Earth's orbit. This is
- 5:44spacetime. Still to come, an update on
- 5:47Lucy's mission to Jupiter's Trojan
- 5:49asteroids, and NASA rules that the
- 5:52trouble plague Starlininer's next
- 5:53mission to the International Space
- 5:55Station will be limited to cargo only.
- 5:57All that and more still to come on
- 6:00Spaceime
- 6:16One of the many exciting missions
- 6:18currently underway is NASA's Lucy
- 6:20spacecraft, which is on its way to study
- 6:22Jupiter's Trojan asteroids. Lucy was
- 6:25launched back in October 2021.
- 6:28It's on a 12-year mission to study the
- 6:30Trojans, two clusters of asteroids that
- 6:33share the gas giant's orbit around the
- 6:34sun. Trojans are families of asteroids
- 6:37kept in gravitationally stable bound
- 6:39groups at the lrangeian L4 and L5
- 6:42positions located 60° ahead and 60°
- 6:45behind Jupiter's orbit around the sun.
- 6:49Lrangeian points are named in honor of
- 6:51the Italian French mathematician Joseph
- 6:53Lewis Lrange who was working on the
- 6:55general free body problem in orbital
- 6:57mechanics. The grungian points are
- 7:00places in space where a gravitational
- 7:02pull of two bodies such as in this case
- 7:04between the sun and Jupiter tend to
- 7:06cancel each other out thereby allowing
- 7:08smaller objects such as asteroids or
- 7:10spacecraft to remain there for extended
- 7:13periods of time. There are five lrangian
- 7:16points known as L1 2 3 4 and 5. Now L1 2
- 7:21and 3 are all along a line connecting
- 7:23the two bodies. Let's say it's the Earth
- 7:25and the Sun. In that case, L1 is between
- 7:28the Earth and the Sun is often used by
- 7:30spacecraft needing an uninterrupted view
- 7:32of the sun, such as the Solar and
- 7:34Heliospheric Observatory satellite SOHO.
- 7:36The L2 position is on the opposite side
- 7:38of the Earth to the Sun. It's home to
- 7:41spacecraft like the web space telescope
- 7:43because it's ideal for astronomy as
- 7:45spacecraft are still close enough to
- 7:47communicate with the earth and can keep
- 7:48the sun, earth, and moon behind them,
- 7:50allowing them to gain solar power while
- 7:52still providing a clear dark view of
- 7:54deep space for their telescopes. The L3
- 7:58position is on the opposite side of the
- 8:00sun to where the Earth is. Because L3 is
- 8:03always hidden from the Earth by the Sun,
- 8:05it's become popular in science fiction
- 8:07as the location for any hypothetical
- 8:09second Earths. But it's the L4 and L5
- 8:12positions which provide stable orbits
- 8:14around 60° in front of and 60° behind
- 8:18Earth's orbit around the Sun. And it's
- 8:20at these locations where Trojan
- 8:22asteroids, such as those orbiting with
- 8:24Jupiter, are commonly found.
- 8:26Jupiter's Trojans are distributed into
- 8:29two elongated curved regions around
- 8:31these lrangian points with an average
- 8:33semic-ircular axis of around 5.2
- 8:36astronomical units. An astronomical unit
- 8:38is the average distance between the
- 8:40Earth and the Sun. 150 million
- 8:42kilometers or 8.3 light minutes. The
- 8:45first Jovian Trojan discovered 588
- 8:48Achilles was spotted in 1906 by German
- 8:51astronomer Max Wolf. So far, more than
- 8:5415,300 Jovian Trojans have been
- 8:56detected. Now, by convention, they're
- 8:58each named from Greek mythology after a
- 9:01figure of the Trojan Wars, hence the
- 9:03name Trojan. It later became convention
- 9:06to name Jupiter's L4 Trojan asteroids
- 9:08after Greek characters and the L5
- 9:11asteroids after Trojan characters.
- 9:13Astronomers estimate there are more than
- 9:15a million Jovian Trojans larger than a
- 9:17kilometer in size. Now that's about the
- 9:20same as the number of asteroids larger
- 9:22than a kilometer in the main asteroid
- 9:24belt between Mars and Jupiter. Many
- 9:27Jovian Trojans appear to be dark bodies
- 9:29with reddish featureless spectra. No
- 9:32firm evidence of the presence of water
- 9:34or any other specific compound on their
- 9:36surfaces has ever been obtained. But it
- 9:39is thought that they're coated in
- 9:40tholines organic polymers formed by the
- 9:43sun's radiation. The Jovian Trojans are
- 9:46thought to have been captured into their
- 9:47orbits during the early stages of the
- 9:49solar systems formation or at the most
- 9:51slightly later during the late heavy
- 9:53bombardment during the migration of the
- 9:55giant planets. Mind you, Jupiter isn't
- 9:58alone to have Trojan asteroids. They've
- 10:01been found orbiting many of the other
- 10:02planets in our solar system as well,
- 10:04including Mars, Neptune, Uranus, and
- 10:06even the Earth. No spacecraft has ever
- 10:09visited a Jovian Trojan. That's where
- 10:12the Lucy mission comes in. Lucy is
- 10:14covering some 6 and 12 billion
- 10:16kilometers, visiting a record-breaking
- 10:18seven asteroids, one in the main
- 10:20asteroid belt, and six Trojans. The
- 10:23mission's principal investigator, Harold
- 10:24Leverson, from the Southwest Research
- 10:26Institute in Boulder, Colorado, says
- 10:28Trojans are leftovers from the early
- 10:30days of our solar system. Effectively,
- 10:32they're fossils of planetary formation
- 10:35and therefore hold vital clues about
- 10:37deciphering the solar systems early
- 10:39history. He says, "Like Lucy, the human
- 10:42ancestor fossil after which it's named,
- 10:44the Lucy spacecraft will revolutionize
- 10:46science's understanding of the solar
- 10:48systems origins. The mission will
- 10:50provide an unparalleled glimpse of the
- 10:52formation of the solar system, helping
- 10:54astronomers better understand the source
- 10:56of volatiles and organics on terrestrial
- 10:58planets, as well as the evolution of the
- 11:00planetary system as a whole. This report
- 11:03from NASA TV. We are going to an amazing
- 11:07variety of objects with this mission.
- 11:09>> The Lucy mission is going to fly past
- 11:11seven asteroids in 12 years with one
- 11:14spacecraft.
- 11:15>> And it's really almost pure luck that
- 11:18allowed us to get as many rich targets
- 11:21as we are. Literally, the planets were
- 11:23aligning to allow us to do this mission.
- 11:26The Lucy mission is named after the Lucy
- 11:29fossil, the Australopythecus fossil that
- 11:32was discovered in the 1970s in Ethiopia.
- 11:35And just like the Lucy fossil
- 11:37transformed our understanding of
- 11:38homminid evolution, the Lucy mission
- 11:41will transform our understanding of
- 11:43solar system evolution. Trojan asteroids
- 11:45are an interesting population of small
- 11:48bodies that are left over from the
- 11:49formation of the planets and they lead
- 11:53or follow Jupiter in its orbit by
- 11:55roughly 60°. If you just look at the
- 11:59gravitational attraction of the sun and
- 12:01Jupiter and put something exactly 60° in
- 12:04front of Jupiter, it's stable forever.
- 12:06So as a result, these objects are really
- 12:09the leftovers of planet formation. The
- 12:12stuff that went into growing Jupiter and
- 12:14Saturn are now trapped in these
- 12:18locations.
- 12:19>> The very first asteroid we get to is a
- 12:21main belt asteroid named Donald
- 12:23Johansson. We named that asteroid in
- 12:25honor of the researcher who found the
- 12:28Lucy fossil. We're use that asteroid to
- 12:30do a rehearsal on our spacecraft to make
- 12:33sure everything is working properly so
- 12:34that when we get to the Trojan
- 12:36asteroids, we're ready to go.
- 12:38>> We're visiting both of the Trojan
- 12:39swarms. In the first orbit, we're going
- 12:41into the leading swarm and we're going
- 12:44to encounter four Trojan targets.
- 12:46>> Earbies, Palm, Lucas, and Orus. And from
- 12:50this, we're going to sample the
- 12:51diversity in sizes and colors and
- 12:54compositions. The first two flybys
- 12:56happened just about 30 days apart. So,
- 12:59it's going to be a pretty busy kickoff
- 13:01to the season of exploring the asteroids
- 13:04in the L4 swarm. And then we'll fly past
- 13:07Earth again and out to the L5 swarm.
- 13:10>> The final object we're visiting, which I
- 13:12must admit is my favorite, is a binary
- 13:15object.
- 13:15>> So, that's two Trojans that orbit a
- 13:17common center of mass. It's called
- 13:19Petroas and Menishius.
- 13:21>> These objects are nearly identical in
- 13:23size that orbit one another. From the
- 13:26Lucy mission, we're going to study the
- 13:28diversity of our targets because that
- 13:30tells us something about their origin
- 13:32and where they came from.
- 13:33>> The interesting thing about small bodies
- 13:35in general is they are the leftovers of
- 13:38planet formation. If you look at the
- 13:40eight planets that we know about, for
- 13:41example, they are highly processed
- 13:43because of internal processing. These
- 13:45asteroids are objects that really
- 13:48haven't changed much from when the
- 13:51planets assembled themselves. And as a
- 13:53result, by studying them, we can figure
- 13:56out the physical conditions of the early
- 13:59solar system, as well as how the planets
- 14:02grew and how they moved around early on.
- 14:06>> All of that will help us form a detailed
- 14:08picture of what these objects really
- 14:10look like. Because right now, our best
- 14:13images are just a point of light. Even
- 14:16using the Hubble Space Telescope or
- 14:19adaptive optics on large groundbased
- 14:21telescopes, we can't see surface
- 14:24details. And it's going to take the Lucy
- 14:26mission to go to these targets and see
- 14:28what they're really made of and what
- 14:30they look like.
- 14:38And in that report from Massa TV, we
- 14:40heard from Lucy principal investigator
- 14:42Hal Leverson and Lucy deputy principal
- 14:44investigator Kathy Olen, both from the
- 14:47Southwest Research Institute in Boulder,
- 14:49Colorado. This is Spaceime. Still to
- 14:53come, NASA says Boeing's trouble plague
- 14:55Starlininer spacecraft won't be carrying
- 14:57any astronauts on its next flight to the
- 14:59International Space Station. And later
- 15:01in the science report, neurologists have
- 15:03identified the five major epochs of
- 15:06brain structure over the course of a
- 15:08human lifetime. All that and more still
- 15:10to come on Spaceime.
- 15:27NASA says Boeing's trouble plagued
- 15:29Starlininer spacecraft won't be carrying
- 15:31any astronauts on its next flight to the
- 15:34International Space Station. Instead,
- 15:36the mission will be limited to cargo and
- 15:38supplies only. The decision comes 8
- 15:41months after the first and only man
- 15:43starliner flight saw the capsule
- 15:45returned to Earth empty with its crew
- 15:47left stranded on the International Space
- 15:49Station for more than 9 months. That
- 15:51followed a series of issues with the
- 15:53vehicle's propulsion and orbital
- 15:54maneuvering systems, as well as its
- 15:56helium pressurization system. And it's
- 15:58not the first time Starliner suffered
- 16:01issues. Faulty computer programming
- 16:04prevented the first Starlininer mission
- 16:05to the space station from even reaching
- 16:07its target. And more faulty computer
- 16:09programming, which luckily was corrected
- 16:11in time, would have caused the Star
- 16:13Liner to be destroyed during its
- 16:15re-entry. There have been other problems
- 16:17with corrosion in the spacecraft's
- 16:18propulsion system as well. Issues with
- 16:21the strength of the parachute webbing,
- 16:22the concerns over the safety of
- 16:24insulation on the spacecraft's wiring
- 16:26harness, and problems with environmental
- 16:29controls inside the spacecraft's cabin.
- 16:32For Starlininer, it's been a case of one
- 16:34problem after another, and it seems
- 16:36NASA's had enough. As well as limiting
- 16:39its next flight to cargo only, NASA's
- 16:41also slashed the total number of
- 16:42Starlininer missions down from six to
- 16:45four. As for Starlininer's next flight,
- 16:47that's the cargo mission, it's currently
- 16:49slated for April next year. If that goes
- 16:51well, then a man mission could happen
- 16:53towards the end of the year. The
- 16:55remaining two flights will also carry
- 16:57crew to the International Space Station
- 16:59until the orbiting outpost is
- 17:00decommissioned in 2030.
- 17:03Starlininer was one of two spacecraft
- 17:05selected by NASA back in 2014 as part of
- 17:08the AY's commercial crew program to
- 17:10transport astronauts to and from the
- 17:12space station. But unlike the other
- 17:15successful applicant, SpaceX's Dragon
- 17:17spacecraft, which has performed
- 17:18flawlessly, Boeing Starlininer has
- 17:21suffered from continuous failures and
- 17:22quality control blunders. It's been a
- 17:25costly disaster for Boeing. SpaceX
- 17:28launched its first man Dragon mission to
- 17:30the space station for NASA in 2020. It's
- 17:33now completed 12 crew change missions as
- 17:36well as several private missions into
- 17:38orbit. This is spacetime.
- 17:56And time now to take another brief look
- 17:57at some of the other stories making news
- 17:59in science this week with a science
- 18:01report. Neuroscientists have identified
- 18:04five major epochs of brain structure
- 18:06over the course of a human lifetime. The
- 18:09findings reported in the journal Nature
- 18:11Communications show how human brains
- 18:13rewire themselves to support different
- 18:16ways of thinking as people grow, mature,
- 18:19and ultimately decline. The study led by
- 18:22Cambridge University compared the brains
- 18:24of 3,82 people between 0 and 90 years of
- 18:27age using MRI scans which map neural
- 18:30connections by tracking how water
- 18:32molecules move through brain tissue.
- 18:34They found the brain structure for an
- 18:36average human life is split up into four
- 18:38pivotal turning points between birth and
- 18:40death. It seems childhood brain topology
- 18:43runs from birth until a turning point at
- 18:46around age nine. That's when it
- 18:48transitions to an adolescent phase.
- 18:50That's an error that lasts up until the
- 18:52age of around 32 on average. The brain's
- 18:55neural wiring then shifts into a more
- 18:57adult mode. This is the longest era
- 18:59which can last over three decades. A
- 19:02third turning point around the age of 66
- 19:04marks the start of an early aging phase
- 19:07of brain architecture. And finally, the
- 19:09late aging brain takes shape around the
- 19:12age of 83 years old.
- 19:14So what's going on inside the noggin?
- 19:17Well, during the early childhood phase,
- 19:19the brain underos network consolidation
- 19:21as a wealth of synapses, that's the
- 19:23connections between neurons over
- 19:24produced in a baby's brain are
- 19:26whittleled down with only the more
- 19:28active ones surviving. Across the whole
- 19:30human brain, connections rewire in the
- 19:32same pattern from birth until about 9
- 19:34years of age. Meanwhile, gray and white
- 19:37matter grow rapidly in volume. So that
- 19:40cortical thickness that's the distance
- 19:41between the outer gray matter and the
- 19:43inner white matter reaches a peak and
- 19:45cortical folding that's the
- 19:46characteristic ridges on the outer brain
- 19:48stabilizes by the first turning point at
- 19:51around the age of nine the brain is
- 19:53experiencing a step change in cognitive
- 19:55capacity as well as an increased risk of
- 19:58mental health disorders. The second
- 20:00epoch of the brain that's the adolescent
- 20:02era sees white matter continue to grow
- 20:04in volume. So organization of the
- 20:06brain's communications network is
- 20:08increasingly refined as measured by the
- 20:11diffusion of water in the scans. This
- 20:13era is defined by the efficiency of
- 20:15connections both within specific regions
- 20:17as well as rapid communication right
- 20:19across the whole brain which is related
- 20:21to enhanced cognitive performance.
- 20:23Neural efficiency is well connected by
- 20:26short pathways and the adolescent era is
- 20:28the only one in which this efficiencies
- 20:30increasing. The authors say these
- 20:32developments of the brain peak in the
- 20:34early 30s which is the strongest
- 20:36topological turning point for the entire
- 20:38lifespan. At age 32, the longest era
- 20:41that of adulthood begins. Brain
- 20:44architecture stabilizes compared to
- 20:46previous phases with no major turning
- 20:47points for 30 years and corresponds with
- 20:50a plateau in intelligence and
- 20:51personality. They also found segregation
- 20:54is more noticeable during this epoch as
- 20:56different regions of the brain slowly
- 20:58start to become more compartmentalized.
- 21:00The turning point at age 66 sees reduced
- 21:04connectivity as white matter starts to
- 21:06degenerate. The last turning point comes
- 21:08around the age of 83 when the brain
- 21:11structure shifts from global to local
- 21:13regions as neural connectivity declines.
- 21:17A long-term study has shown that water
- 21:19fluidation doesn't have any negative
- 21:21effects on brain development. In fact,
- 21:23the findings reported in the journal
- 21:25Science Advances actually found a slight
- 21:27boost in cognition in children. Previous
- 21:30studies looked at exposure to very high
- 21:32levels of fluoride far beyond
- 21:33recommended standards. So, the authors
- 21:35of this new research wanted to study
- 21:37levels representative of what one would
- 21:39usually find in their tap water. They
- 21:42looked at language and math test results
- 21:43from around 58,000 United States high
- 21:46school kids in 1980 and the water
- 21:48fluidation levels they would have
- 21:50experienced since conception. After
- 21:52accounting for other factors, they found
- 21:54kids continuously exposed to at least
- 21:560.7 mg per liter of water fluoride had
- 21:59better test results, followed by those
- 22:01exposed to similar levels for just part
- 22:03of their childhood.
- 22:05China's People Liberation Army has
- 22:07reported the successful test of a new
- 22:09type of non-uclear hydrogen bomb. A
- 22:12report in the Chinese Language Journal
- 22:14of Projectiles, Rockets, Missiles, and
- 22:16Guidance claims the new weapon generates
- 22:18a white hot fireball that can last 15
- 22:21times longer than a TNT blast. The 2 kg
- 22:24device uses magnesium hydide, a
- 22:27magnesium based solid state hydrogen
- 22:29material, which generated a fireball of
- 22:31over a,000° C. This material stores
- 22:35considerably more hydrogen than a
- 22:36pressurized tank and was originally
- 22:38developed to bring the gas to off-grid
- 22:40areas where it could then be used to
- 22:41power fuel cells for clean electricity
- 22:43and heat. When activated by conventional
- 22:46explosives, the magnesium hydide bomb
- 22:48underwent rapid thermal decomposition,
- 22:51releasing hydrogen gas that ignited into
- 22:53a sustained, rapidly spreading inferno.
- 22:56The chain reaction begins when
- 22:58detonation shock waves fracture
- 23:00magnesium hydide into micron scale
- 23:02particles exposing fresh surfaces. Under
- 23:05constrained detonation, peak over
- 23:07pressure reached 428.43 kilopascals at 2
- 23:10m, about 40% that of TNT's blast force,
- 23:14but with a far greater heat projection
- 23:16range.
- 23:18Well, the doomsday countdown to digital
- 23:20ID is now on. This time next week,
- 23:24Australia's controversial new social
- 23:26media bans for children under the age of
- 23:2816 will come into effect. The world
- 23:30first legislation is being marketed as a
- 23:32way to protect kids from bullying. But
- 23:35it doesn't stop kids using left-wing
- 23:37social media platforms like Blue Sky or
- 23:40for that matter chat rooms in many of
- 23:41the most popular computer games.
- 23:45In reality, it's a thinly disguised
- 23:47Trojan horse designed to force all
- 23:49Australian adults to adopt a digital ID,
- 23:52as if they want to retain access to
- 23:54their own social media accounts. It's a
- 23:56way around the public's objection to the
- 23:58defeated Australia card ID scheme of the
- 24:001980s, which was overwhelmingly rejected
- 24:03by the people. So, why the
- 24:06fear-mongering? Well, digital ID will
- 24:09allow faceless bureaucrats, security
- 24:11organizations, and politicians to
- 24:13develop a big brother style digital link
- 24:15connecting everything, monitoring
- 24:17everything you do, where you go, what
- 24:19you look at, and even what you say. In
- 24:22the process, providing fact-based
- 24:24insights into what you're thinking. Then
- 24:26there's the issue of security and how
- 24:28easily your digital ID and all it
- 24:30contains about you can be hacked. Your
- 24:33digital ID will be the Australian answer
- 24:35to Beijing's social credit scheme, where
- 24:38those not considered worthy by China's
- 24:40Communist Party face restrictions in
- 24:42where they can live, where they can go,
- 24:44what they have access to, how they can
- 24:46travel, and where their children can go
- 24:48to school. Australians saw the first
- 24:50hints of what's to come during the COVID
- 24:52pandemic when voluntary digital ID
- 24:54schemes were repeatedly used by police
- 24:56to track people's movements. Technology
- 24:59editor Alex Haravo from techadvice.life
- 25:01life says in simple terms this new
- 25:04digital ID scheme will be a key step in
- 25:06the erosion of people's rights. It's
- 25:09only one small slice but step by step
- 25:12those rights will disappear and it all
- 25:15starts next week.
- 25:16>> Look there seems to be this concerted
- 25:18effort globally to want to set up
- 25:20digital ID and this clearly is something
- 25:22that will remove anonymity from the
- 25:24internet. everything you do will be
- 25:25tracked and it's all being done under
- 25:27the guise of won't somebody protect the
- 25:29children and you know Roblox for example
- 25:31has algorithms you got to take a photo
- 25:32of your face and they're looking at the
- 25:34various things you've been doing in the
- 25:35system but ultimately we're relying upon
- 25:37algorithms to figure these things out
- 25:39and the only real way of doing it is to
- 25:41get some sort of an ID from a parent
- 25:43from you know a passport something to
- 25:45prove that you are of a certain age but
- 25:47again this is going to remove anonymity
- 25:50from the internet and everything that
- 25:52you will do will be tracked and so there
- 25:53is a movement now to not comply with
- 25:56digital ID. But this is happening
- 25:58globally around the world. Governments
- 26:00are all coming together to put these
- 26:02social media bans in place. Malaysia is
- 26:04doing it. The UK wants digital ID. And
- 26:06uh I don't know if VPNs are going to be
- 26:07enough. There needs to be a push back
- 26:09from the public to say no. And even in
- 26:11Australia, we have a couple of young
- 26:12kids who are taking the government to
- 26:14the high court to have the digital ID
- 26:16system blocked. So this seems to be a
- 26:18watershed moment in um the modern
- 26:20civilization. Is this really part of a
- 26:23surreptitious effort by governments to
- 26:26just gain control over everything you
- 26:28have access to, all the information you
- 26:30get?
- 26:30>> Well, it look it certainly seems that
- 26:32way. I mean, everything that the
- 26:33governments have been trying to do, even
- 26:34in Australia, we had conservative and
- 26:37socialist governments and they tried all
- 26:39sorts of firewalls and they tried
- 26:40various things to to try and control
- 26:42people.
- 26:43>> Yeah, we had the attempt of an Australia
- 26:45card years ago and uh the citizenry
- 26:48resoundly said no to that. But it
- 26:50doesn't stop the bureaucrats or or the
- 26:52politicians from wanting to implement
- 26:53that. We had a situation where we had
- 26:56special ID for co that simply gave the
- 26:58police a chance to to track everyone's
- 27:00movements.
- 27:01>> Yeah. Yeah. Papers, please. As we saw in
- 27:03Nazi Germany. Look, the problem is that
- 27:06the unelected deep state globally wants
- 27:08control. They want to stay in power.
- 27:10They want to do the things they have
- 27:11been accused of doing um and maintain
- 27:13power and debase the currency and do all
- 27:15these things that some claim are
- 27:17conspiracies. But it's clear that if you
- 27:19can maintain your position of power and
- 27:21you can worm your way through the
- 27:22system, why wouldn't you do it? And
- 27:23we've seen that time and again
- 27:25throughout history and in the 21st
- 27:27century with all of the digital
- 27:28technologies now at the disposal of big
- 27:30tech, but also government. Well, we're
- 27:32seeing them work together and trying to
- 27:33hold people down. I mean, thank goodness
- 27:35for the United States and their first
- 27:37amendment. The deep space is fighting
- 27:39back and uh it's up to us as citizens,
- 27:42global citizens to say no, we don't want
- 27:44unelected people to usurp our privacy.
- 27:48>> We're sort of seeing human rights
- 27:50disappear one by one. And it's not that
- 27:52they're being taken from us. The
- 27:54citizenry are gladly giving them up, it
- 27:56seems, for an easier life.
- 27:57>> Benjamin Franklin said that if you give
- 27:59up a little liberty for a little
- 28:01security, then you deserve neither. And
- 28:03this is where people abdicating their
- 28:06responsibilities as human beings to big
- 28:09brother is the fast track to dystopia. I
- 28:11mean that's why we had Animal Farm.
- 28:12That's why we had 1984 from George
- 28:14Orwell. That's why we've had so many
- 28:16movies and TV shows about dystopia
- 28:18because people are worried. I mean these
- 28:20are warnings to ourselves to not let
- 28:22this sort of thing happen to us. We live
- 28:24at a time where as Ronald Reagan said,
- 28:26freedom and liberty is not passed down
- 28:28through the bloodline but must be fought
- 28:30for and protected by every generation.
- 28:32And uh we stand at the point at which
- 28:34the future generations of this planet
- 28:36could be living under dystopia. Let's
- 28:38hope that that doesn't happen.
- 28:39>> That's Alex Aharavoy from
- 28:40techadvice.life.
- 28:42And just in case you think advanced
- 28:44algorithms will circumvent all the
- 28:46problems of digital IDs, think again.
- 28:48Remember these are the same
- 28:50sophisticated algorithms which keep
- 28:52flagging up space-time posts displaying
- 28:54astronomical images of exoplanets as
- 28:56possible pornography. I mean, granted it
- 28:59is space porn, but that's not what the
- 29:01algorithms are thinking. This is
- 29:03spacetime.
