Elon Musk warns us with this Cosmic blast that can strike Earth anytime our journey on planet
Earth appears to be a relatively safe alternative when compared to being burned on Mercury choked
on Venus or Frozen on Pluto in the past though life here on Earth has been dangerous from the
worst mass extinctions to the most pervasive ice eras close calls with extraterrestrial dangers may
be to blame for some of the worst natural disasters the planet has ever experienced
whether it's massive clouds of engulfing dust or magnetic neutron stars astronomers disagree on
which Hazard is the biggest but most believe that the world is still on an unnerving roller coaster
as Elon Musk discusses the biggest astronomical dangers to life on Earth fasten your seat belts
and take a deep breath hello everyone welcome back to Elon Musk Evolution where we bring you
the most recent news about Elon Musk and his multi-billion dollar companies space news and
the latest science and technology but before we begin make sure you subscribe to our Channel and
click the Bell icon so you don't miss out on any of our amazing videos according to a new theory
that contends huge bursts of space radiation may have contributed to some of our planet's biggest
Extinction events the survival of life on Earth may depend on enormous explosions on the other
side of the Galaxy according to musk massive amounts of high energy gamma ray radiation can
be released into space during the explosions which are gamma ray bursts that are theorized to result
from the Collision of two stars according to the study's findings these explosions may be a factor
in the ozone layer's loss from the earth the ozone layer is damaged allowing UV radiation to reach
the Earth's surface and mutate species genes currently scientists are starting to link the
timing of these gamma-ray bursts to extinctions on Earth that can be dated by looking at the fossil
record we discover that a form of gamer ray burst a brief gamma-ray burst is probably more relevant
than a longer gamma-ray burst study author Brian Thomas of Washburn University in Topeka Kansas
said in a statement the amount of radiation not the period is more significant there are two
types of gamma-ray bursts a longer brighter burst and a shorthand burst which is brighter and lasts
for less than a second it appears to emit more radiation musk explained the impacts on Earth
would be much more enduring if such a burst occurred Inside the Milky Way these radiation
bursts cause free oxygen and nitrogen atoms to collide as they enter the Earth's atmosphere and
some of these collisions result in the formation of nitrous oxides which deplete the ozone layer
in the atmosphere nitrous oxides have a lengthy Half-Life and continue to degrade ozone until
they precipitate as rain the short burst could be the result of collisions between stars like
those between massive neutron stars or black holes these star collisions are likely to occur
once per 100 million year in any given Galaxy according to the astronomer's best estimate at
this pace Earth would have experienced several of the short but powerful occurrences over the
span of its 4.5 billion year history our planet's life may be negatively impacted by the ozone layer
being destroyed in a number of ways the effects of radiation blast on the world's animals and
vegetation might have a devastating impact on the planet's food webs and potentially trigger
mass extinction events improved and cumulative data from NASA's Swift satellite which observes
gamma-ray bursts in action in other galaxies are making a stronger case for the strength
and danger of the brief burst to life on Earth the heavy form of iron and other unique elements that
can only be produced when radiation events impact Earth are among the signs of previous bursts that
scientists are searching for Thomas is presently collaborating with paleontologists to compare the
concentrations of this heavy iron to fossil evidence of Extinction episodes we attempt
to look for parallels with extinctions because as I work with several paleontologists but they
are hesitant Thomas added so if you go and give a talk to paleontologists they're not very into it
but to astrophysics it appears pretty feasible and just recently an incredibly bright and protracted
pulse of high energy radiation that passed over Earth on Sunday October 9th as astronomers all
across the world captivated gamma-ray bursts the most intense kinds of explosions in the
cosmos are among the most brilliant occurrences that have ever been observed and they are the
source of the emission a wave of X-rays and gamma rays that race through the solar system on Sunday
morning Eastern Time trigger detectors on wind satellite the Neil Garrow Swift Observatory and
nasus Fermi gamer race-based telescope among other instruments new observations are still being made
at the location which attracted telescopes from all around the world to observe the aftermath
the gamma ray astronomers conference the 10th Fermi Symposium which is currently taking place
in Johannesburg South Africa got off to an unexpectedly spectacular start thanks to the
explosion known as grb 221009a and Judy recusa in a Fermi deputies project scientist at NASA's
Goddard space flight center in Greenbelt Maryland who is present at the meeting stated it's safe to
say this meeting really kicked off of the bang and everyone's talking about this it
took the signal which came from the direction of the constellation sajida 1.9 billion years
to reach Earth It is believed by astronomers to be the first Cry of a brand new black hole
one that emerged in the center of a massive star that was collapsing under its own weight in these
conditions a developing black hole propels strong Jets of particles that are flying at speeds close
to light X-rays and gamma rays are released as the jets fly into space as they pierce through
the star the burst also gave two experiments on the international space station NASA's nicer
x-ray telescope and a Japanese detector known as the monitor of all Sky x-ray image or Maxi
they're long-awaited first opportunity to combine observations the connection known as the orbiting
high energy monitor alerts Network or oh man was launched in April it enables activities that
previously needed interaction by scientists on the ground such as directing nicer quickly to Outburst
indicated by Maxi as soon as the source became visible to the telescope oh man gave an automated
alarm that allowed nicer to follow up within three hours according to zaven our zirmanian the nicer
science lead at Goddard future chances might lead to reaction times of a few minutes new information
on Stellar collapse the creation of black holes the behavior and interaction of matter close to
the speed of light the circumstances in a far away Galaxy and much more is revealed by the light from
this ancient explosion it could be decades before another grb this by right is observed
a preliminary investigation shows that fermi's large area telescope picked up the explosion
for more than 10 hours the burst brightness and length may be due in part to the fact that for
a gamma-ray burst it is located quite close to Earth Roberta Pierre a member of the Fermi
lat collaboration and a doctoral student at the Polytechnic University of Bari in Italy led the
initial Communications about the burst this burst is much closer than typical grbs which is exciting
because it allows us to detect many details that otherwise would be too faint to see she
said however regardless of distance it is also one of the brightest and most explosive bursts
ever witnessed making it twice as thrilling more over the sun's regular Transit through the spiral
arms of the Milky Way produces the majority of the celestial dangers to life on Earth every 250
million years our solar system completes an orbit around the Galaxy asteroid or Comet strike it's
difficult to eradicate all life on Earth yet it is simple to trigger major extinctions the last big
mass extinction occurred 65 million years ago as a result of a massive Collision Comet Swift Tuttle
has 28 times the devastating energy of that catastrophe and might strike Earth in 4479 a
random encounter the Galaxy is teeming with Stars playing at Stellar debris and black holes a random
encounter we could all perish if one were to pass through our inner solar system and gravitationally
expel the Earth Supernova supernovas have frequently damaged Earth yet we've managed to
survive without suffering too much it takes a type 2 Supernova to get within 25 light years of Earth
for us to be in danger which is a very unlikely scenario our own sun will ultimately burn us up
the sun's growing energy output will melt the oceans after 2 billion years and definitively
end all life on Earth musk finally explained you probably immediately consider nuclear war global
warming or a widespread pandemic disease is the biggest threats to human survival but even if
we succeed in overcoming these obstacles are we truly secure when you're unaware of the dangers
in outer space living on our blue little planet feels safe musk further explained and that's it
