Let's step into the unsettling world of the cosmos
and cover some facts that could make your brain short circuit.
"Voyager 1 will outlive the Earth" Voyager 1 is currently the farthest human-made object
from the earth and a distance of nearly 24 billion kilometers or 15 billion miles away
it's already crossed into Interstellar space breaking through the outer boundaries of our
solar system and Interstellar space is big and on its current trajectory the spacecraft appears to
have a clear shot through the cosmos that will allow it to continue traveling for trillions of
years before it comes anywhere remotely close to a star this means that long after the sun
expands and possibly engulfs the Earth this piece of human history will still be traveling through
the dark emptiness of space 9. the real shooting stars we've all heard the old adage telling us
to make a wish every time we see a shooting star which are not really stars but simple
small objects burning up in our atmosphere but shooting stars really do exist hyper velocity
stars are a type of star that is broken free from its Galactic home and can travel through space at
speeds reaching nearly 2 million kilometers per hour that's 1.2 million miles per hour stars like
these are often the result of a massive Galactic slingshot where the gravitational forces around
the supermassive black hole found in the center of most galaxies accelerate the Stars until they have
enough momentum to break free and begin their solo Journeys through space eight attacks from
space our Modern Life complete with cell phones computers and the internet is dependent not only
on the infrastructure we've built on Earth but also on the many satellites in orbit above the
planet wirelessly connecting every quarter of the globe all of this can be threatened in a moment by
wild forces and energies traveling through the cosmos whether gamma rays From A Distant Supernova
Cosmic winds carrying countless charged particles or a massive solar ejection from our own Sun the
Earth could go dark with little to no warning at all there's very little we could do to predict
this as it can happen at any time would we be able to handle losing all forms of communication in an
instant 7. an object so big it defies physics our home galaxy The Milky Way stretches out across 100
000 light years of space which seems like a pretty large object but it's nothing compared
to the largest structure astronomers have ever found in the universe the large Quasar group or
lqg is big the smallest diameter of this object is still a staggering 1.4 billion light years
with the widest point of the lqg reaching a mind-boggling 4 billion light years across
composed of at least 73 quasars this object is so big that it literally breaks the conventionally
held laws in the current field of astronomy what would it be like to look at a structure 40
000 times the size of our galaxy 6. space can change your DNA spending time in space can take
its toll on the body muscle atrophy spinal decompression and losing calluses on your
feet are only a small part of what can happen to you if you spend long enough out of Earth's
atmosphere NASA was able to determine some of the extent of this by taking a pair of twin astronauts
Scott and Mark Kelly in running tests after one of them spent a year aboard the International Space
Station after returning to earth scientists were able to find out that Not only was Scott
now two inches tall polar and had different gut bacteria than his twin but his DNA also showed
significant differences as well and unlike the height change that eventually returned to normal
the changes in his DNA appear to be permanent the only conclusion was that the stress from spending
too long in space causes the cells of the body to rewrite the genetic code possibly in an attempt to
handle this new environment 5. dark flow is moving galaxies there's something that's sitting in the
patch of Sky between the constellations Vela and Centaurus first detected by researchers at
NASA's Goddard space flight center a group of Galaxy clusters were moving towards this area
and space at incredible speeds named dark flow the team believes that there must be something
beyond our visual Horizon that's generating that unusually powerful pull but as of now the team
has few you ideas of what it could be according to their models if it is a physical object it would
be a behemoth that should be massive enough to impose somewhat of a tilt on the universe causing
all this matter to fall towards it but a mega structure like this shouldn't really exist in
our universe according to the copernican principle which has led some astronomers
to theorize that this poll may be coming from beyond our universe 4. the long galactic year
we all know that it takes roughly 24 hours for the Earth to complete one rotation on its axis
giving us a day and that it takes 365 days for us to make a complete Journey around the Sun but
there is another rotation that our planet makes as our entire solar system makes its way around
Sagittarius A star that sits at the center of the Milky Way this Galactic Year takes between 225 to
250 million years to finish this means that the birth of our universe the Big Bang only happens
61 Galactic years ago the human species only emerged one one thousandths of a galactic year
ago dinosaurs went extinct just over a quarter of a galactic year ago with life itself emerging on
Earth 16 Galactic years ago what could happen over the next Galactic Year will we still be here three
stars can be reborn at the end of the lives of massive stars their last dying breath is made in
the form of a supernova exploding and spewing its material far out into space well its dense core
remains behind but this may not always be the end astronomers are now finding that sometimes
when a star goes Supernova it can also begin to suck in matter from its neighbors and if it draws
in enough material it can reignite itself and begin its Life Anew this Cosmic defibrillation
can theoretically happen again and again creating a stellar heartbeat spanning millions of years to
extraterrestrials may be scared the Dark Forest Theory based on probabilities drawn from things
like the Fermi paradoxin Drake's equation many people have found themselves wondering if the
likelihood of intelligent an extraterrestrial life is so high why haven't we found any or why haven't
any found us well one Theory called the dark force theory has a simple explanation they're scared
there may be countless civilizations throughout the universe that pop up all the time but if one
gets Advanced enough to locate another that's less technologically advanced what's to say
another more advanced civilization hasn't already found them not to mention the possible barriers
in culture and language that could easily lead to tensions and disagreements would it be worth the
risk of possibly drawing attention to yourself or would it be safer to fear other civilizations and
remain isolated in that dark Forest of the cosmos one what life may be out there if that theory is
wrong and there are other civilizations out there that will contact us at some point we may be in
for a surprise when contact is finally made for a long time time scientists Focus their search for
life on carbon-based organisms their reasoning being that carbon-based life is very abundant on
our planet so why not on others but experiments have shown that carbon is not the only element
that can form organic compounds that give rise to life among the contenders are silicon which
can form stable bonds with some elements and may be more favorable than carbon under certain
conditions found on some exoplanets ammonia is an extremely common compound that's found throughout
our galaxy and is almost organic and some metallic compounds which could lead to some interesting
chemistry and living organisms in addition to this the properties of ammonia-based life also allowed
to exist beyond the understood habitability zones where liquid water can exist could Titan
hold life within its oceans of ammonia below its surface thanks for watching if you enjoyed this
