The cessation of the universe's expansion poses catastrophic scenarios for life and the planet. In the event of a Big Crunch, the universe would collapse into a super dense and hot state, making survival impossible due to extreme heat and radiation.

What would happen if the
Universe stopped expanding?
By: Jashandeep Sarah 591705 Theories on what could happen The Big Chill The last Stars go out,
and we lose light from space
because of how far we are apart Stars lose access to
raw material needed for
star formation Planets, Stars and Galaxies
are very far apart from each other The Universe will get colder
and colder, since that energy
is so spread out The energy from the Big Bang
keeps spreading out for eternity The Universe DOESN'T
stop expanding The Big Crunch We can say this because
that super dense state could
be the Big Bang before it exploded This might have already
happened and could be
the life cycle of the Universe,
it explodes, contracts, explodes
and etc The Universe contracts and
all matter returns to a super
dense state If the average density of
the Universe is enough to
stop expansion, the Universe
will collapse on itself The Universe doesn't expand forever,
the direct consequence of the Big Bang What will happen to us Based on the Big Chill And if a genius finds the solution
to Global Warming and we conserve
resources, then there's always the time
bomb we orbit that could engulf us Like Global Warming is a big problem
right now and because of it we are
exposed to the sun's rays more, so
we could burn to death before the Chill However if this is the fate of
the Universe then we would die
from something else before looking for
resources in space It would force us to conserve
resources since we would be too
far to try and get some from other
galaxies The Universe expands forever
becoming cold, vast and dead Based on the Big Crunch So sadly we would die once we got into
that super dense state and wouldn't live
to see the Big Bang Finally theirs radiation, which we couldn't
withstand while being beside a star as big as the sun
so we would die in seconds The Big Bang was roughly 10 Billion
degrees and Fire fighter suits can withstand
1000 degrees of heat, but not for long So we would ultimately be wiped out,
however if we go through a miracle and live
there's more that will kill us It would destroy the planet
because the Universe will collapse
and Earth will go into that hot super
dense state Why is the Universe expanding anyways? The Big Bang Also imaged heat of the Big Bang
in fine detail by Cobe and WMAP probes Some proof we have to back
this up is radiation we find
in space which could be
remnants of the Big Bang This energy then got spread
out and got cooler and cooler,
but the Universe got bigger
and bigger This energy was pushed
out because of the big
explosion that happened So it was a small extremely hot
spec of energy Helium, Hydrogen and Lithium
were fused in the first few
minutes of the Big Bang Then there was a tremendous
explosion, which caused the
Universe back then to expand 12-14 Billion years ago the
Universe was a few mm across The theory for the origin of
the Universe The Hubble Constant Edwin P. Hubble discovered the
Universe has been expanding
after an explosion that took
place 13.7 Billion years ago Right not the Universe is
expanding roughly 74.3 km
per second per megaparsec
( A megaparsec is roughly 3
million light years) Hypothesis If the Universe stopped expanding or continued then
Humanity would be doomed because of multiple
fates that only lead to our extinction
