not to alarm you or anything but there's a black hole pointing her squarely in the face Yes you
heard that right scientists have reclassified a Galaxy after finding that the super massive black
hole in its Center has changed Direction and guess what it is now aiming right at us welcome to lab
360. it's time to explore the Galaxy in question is found 657 million light years away from Earth
and goes by the catchy name of pbcj 233.9 but for convenience we are going to call it just PVC for
now scientists started to study this galaxy as it showed peculiar properties their hypothesis
was that the relativistic jet of its super massive black hole had changed its direction
and to confirm that idea They carried out a lot of observations PBC was previously classified as
a giant radio Galaxy because at one stage it sent out jet material on either side which measures a
mind-boggling 4 million light years across around 40 times the size of our own Galaxy
it was quite a shock then when astronomers looked into PBC and realized it was pointing right at us
it means the galaxy has moved by a 90 degree angle and it's now a blaze R which means a Galaxy point
which has jet points pointing at Earth the jet material from the black hole has created to huge
lobe s on either side of the Galaxy and they are the most immediately notable thing when observed
with radio waves the fact that we see the nucleus is not feeding the lobes anymore means that they
are very old they are the relics of past activity whereas the structures located closer to the
nucleus represent younger and active Jets it's not exactly clear how this could have happened
one guess is that PBC collided with another galaxy which could explain how the angle of axis change
either way this discovery affirms that we do not know much about black holes let alone the
universe what do you think now coming to the more concerning part does this pose a threat
to our solar system super massive black holes are incredibly far away from Earth with the closest
one located about 26 000 light years away in the center of our Milky Way galaxy even with the super
massive black hole pointed directly at us its gravitational effects on Earth would be negligible
furthermore black holes do not emit any light or radiation that could harm us instead
they are detected through their gravitational effects on nearby matter such as stars and gas
so while a super massive black hole pointed directly at Earth would certainly be a fascinating
astronomical phenomenon to observe it would not pose a danger to our planet and yes we need to
learn a lot more about the topic while it's highly unlikely that a supermassive black hole would
start coming towards Earth but if it did it would take millions of years for it to approach us and
we would likely have plenty of time to prepare and take action however let's assume that it
is indeed coming towards Earth in that case the view from mirth would gradually change over time
initially the black hole would appear as a distant point of light in the sky much
like a star as it gets closer its gravitational pull would become stronger and it would begin to
distort the light from stars behind it creating a phenomenon known as gravitational lensing
the closer the black hole gets the more pronounced this effect would become
eventually the black hole would get close enough that its tidal forces would start to affect the
Earth this would cause the Earth to deform stretching it out into an elongated shape
as the black hole got even closer its gravity would become strong enough to tear the Earth apart
this would happen well before the black hole actually made contact with the planet
the Earth's material would be gradually sucked into the black holes Event Horizon
which is the point of no return Beyond which nothing can escape the black hole's gravity
while this scenario is highly unlikely to happen if it does will it be the end
and what would we see while falling into the black hole let's explore the Milky
Way contains over 100 million black holes but detecting these has been extremely difficult
however in April 2019 The Event Horizon telescope saw the first ever direct image of a black hole
a super massive black hole at the center of the giant elliptical galaxy named m87
the boundary of a black hole is known as an event horizon although not a physical boundary it is a
point in space beyond which it is impossible to escape the black hole's gravity once something
passes The Event Horizon and falls into the black hole it can never come out of it again
if you fell into a black hole theoretically speaking gravity would stretch you out like
spaghetti though your death would come much before you reach the singularity but what if you could
enter a black hole how would you do it the first thing would be to choose a supermassive black hole
like the one with an m87 which is over 3 million times wider than Earth to visit this way you would
be very far from Singularity when you went over the Event Horizon about 12 billion miles far
you would float for a long while and may even last as long as a year before you reach your end
what could be avoided though are black holes with accretion disks
only about one percent of supermassive black holes accumulate these fast spinning rings of matter
such powerful magnetic fields would instantly shut down your nervous system and stretch your atoms
into thin rods till you dissolved into Oblivion if you had to visit such a black hole then it should
be entered perpendicular to the disk far from the edge of the fiery ring as you near the black hole
you'll see the light of the universe warped by the black holes intense gravity the sky will have
streaks of light from the stars and because the black hole bends the light that bounces off it you
might see duplicated objects around you you will see the entire formation and history of the black
hole since its Inception the concept of time slows interminably near a black hole's intense gravity
for the real world you have slowed so much that you appear Frozen if seen as an image on the
Event Horizon however for you the motion of the universe has accelerated if you look back out
as you flow toward the singularity you may see the universe go past you only without you in it
far-fetched and Beyond the realm of theoretical physics as of now there is one means of Escape
if the black hole is a wormhole it could take you into another part of the universe
spaghetti feed No Doubt but who knows there could be someone or something on the other side
that could pick up the pieces of your destroyed Quantum information and make you whole again so
would you like to travel to the other side of the universe or whatever lies inside the black hole
thank you
