this week the large hadron collider was turned on again as the world observed keenly holding its
breath along with the collider the debate was back on as well if the world would end because of it
but fortunately we survived but would be tomorrow or the day after that the large hadron collider
may be our own creation but the universe itself has so much going on that it could all fall apart
any second imagine if physics suddenly changed or two universes in the multiverse suddenly collided
what if dark energy vanishes or the black holes become extremely violent
and it all can happen the very next second still alive and watching good the universe
is a scary place to live in but it is going to end sometime maybe tomorrow
maybe 22 billion years from now welcome the factnomenal and today let's find out what are
the most possible 10 ways the universe will come to an end and how much time do we have
the quantum physics theory implies that because of quantum particles the universe fundamentally
exists in a state of instability but observing the values of quantum physics particles some
astrophysicists believe that the universe is teetering towards stability and if the universe
did become stable quantum physics will grow weird and give birth to a universe inside our own that
will have different properties and expand at the speed of light destroying everything in its path
we all have heard the saying ashes to ashes and dust to dust right the saying insinuates that
we are made of dust so must return to dust but does the same logic apply to the universe as well
if the universe emerged from a singularity during the big bang does it have to return to the
singularity before the big bang it is theorized that all matter in space existed as a singularity
an infinitely dense point in the abyss of nothing but then for some reason an explosion happened
everywhere all at once and the matter expanded outward at an astonishing rate and the universe
came to be the big bang theory is the most well evidenced and solidly reasoned theory of the
origin of the universe according to theoretical physicists who believe that the universe is
supposed to return to the state of a singularity at the end of its days believe that the whole
process will essentially reverse in short the big crunch will be the stark opposite of the big bang
currently the universe is expanding due to dark energy having an upper hand over gravity
but that may not be the case in the long run as the history of the universe has taught us
that dark energy wasn't always there to expand the universe in fact after the initial rapid
expansion due to the big bang the universe slowed down substantially until the dark energy jump
started the expansion once more according to the big crunch theory gravity will eventually
overcome dark energy in the eternal tug of war between the two forces this means the expansion
of the universe would slow down to the point that it would halt and as gravity would start
winning it would pull everything back together and the universe would contract instead this
contraction will pull all galaxies stars planets black holes nebulas and constellations together
and continue to compress them until they become an infinitely dense singularity again then what
would be left are the same conditions that the universe had before the big bang all the matter
of the universe condensed into an infinitesimal point the primordial singularity however
this doesn't seem to be happening anytime soon as based on our current knowledge dark energy still
has a prominent lead on gravity and the universe appears to be expanding at an accelerating rate
till now we have explored the possibilities of either gravity overcoming dark energy
or the universe maintaining the status quo towards the universe's end of days
but what if the influence of dark energy keeps increasing in yet another theory
about the universe which starts with the word big astrophysicists proposed that there is a chance
that gravity will lag more and more as time passes so dark energy will drive the acceleration to the
extent that the universe would not be able to handle it anymore and tear it apart into shreds
hence the big rip the most horrifying part of this theory is that unlike other theories the
theorists have a specific time frame for this one nearly 16 billion years this is long before
the stars will extinguish or black holes will evaporate out of existence there would still
be millions of galaxies existing in the universe that would have to endure this cataclysm if there
is a scenario where a cosmic apocalypse could happen everywhere all at once this would be it
if gravity does win eventually some optimistic astrophysicists think the possible end we are
calling the big crunch will also harbinger another beginning the big bouts in this scenario after
gravity wins the rivalry with dark energy and pulls every single atom in the universe to a
cosmological singularity the big bounce takes it even one step further the theory proposes that the
process of rapid compression would culminate in another big bang down the line and a new universe
would be born out of this recycling process as much as this theory sounds like a happy ending
physics tends to disagree with this fairytale-like explanation of the universe's life cycle
some scientists have tried to make sense of it proposing that perhaps the universe
doesn't go the whole way back to a singularity instead it gets very close and then is repelled
by a force similar to the one that repels the ball when you bounce it off the floor
in summary the big bounce is a combination of the big crunch and big bang happening
one after the other if this theory is by any chance correct then that means our universe
could be the first 50th or 5 millionth universe in an oscillating universe theory
but what if it is too late before gravity could get an upper hand and dark energy would pull
the biggest escape of the universe what if gravity never gets strong enough to overcome the expansion
of the universe and galaxies would keep drifting apart like tragic lovers never to meet again
the voids between galaxies will become wider and wider and galaxies would become isolated pockets
of the universe totally self-dependent on their own resources resources that will exhaust over
time as one after the other stars will die in every galaxy they would become darker and darker
losing not only light but heat as well the universe follows the same rules as
any thermodynamic system and they all end up the same way with heat evenly distributed
throughout as heat distributes the temperature will drop and galaxies will wound up losing
the heat and energy required to ignite new stars and eventually these galaxies will go
out indistinguishable from the eternal darkness engulfing them these galaxies won't just vanish
because they still have matter in them but there will be no heat to bring it to order so matter
will exist in particle form and its motion will be totally random as they would have no
energy to exchange between them the universe will achieve an equilibrium albeit a very
chilly one and time will stand still as even hell would freeze over this is the heat death
that could very well be the end of the universe as well interestingly dark energy isn't the only
suspect for causing this probable armageddon it can very well happen another way as well
a certain number of astrophysicists believe that all the matter in the universe is revolving around
one or the other black hole these anomalies on one hand support the big bang theory as these are
living and breathing singularities in our universe while on the other hand they also contradict
the idea of a singular cosmic singularity mathematically but it is evident that black holes
being an absolute champion of gravity attract a lot of matter around them and then devour them
faster than the chips you devour while watching stranger things on your couch almost every galaxy
that is the powerhouses of almost all the matter and energy that exists in the universe also houses
a super massive black hole in the center a large part of the theory about the end of the universe
which involves heat death by black holes involves them devouring stars or even entire galaxies
as they would eventually fall into the black hole's event horizon if the universe is finite
then it is a certainty that one day black holes would ultimately devour all the surrounding matter
and we would be left with a very dark and gloomy universe and that would only suck because you see
it would be entirely made of nothing but black holes now and then there would be a flash of
light almost like lightning whenever an object was pulled close enough to a black hole to emit energy
and then it would fall dark again but as gravity would swallow everything through these black holes
the universe would start looking like an abyss eventually more massive black holes would start
pulling smaller black holes towards them and start devouring them and they would become even larger
enabling them to reach for more black holes but interestingly we are not even close to
the end of the universe yet over time black holes would shed most of their mass as well due to the
process that is called the hawking radiation and as the last of the black holes will fade
away the universe will achieve equilibrium made of nothing but subatomic hawking radiation particles
in previous theories we observed that time froze because of the universe coming to an end
whether it was by contracting into a singularity ripping apart or freezing over due to lack of heat
in all of these cases the universe ends first and then time ceases to exist but what if it happened
the other way around astrophysicists often credit the big bang not only for beginning the universe
but also for the beginning of time however the latter part of that theory is often challenged
by many scientists who believe that time has always existed and always would this interesting
theory actually plays on the probability of times omnipresence if time does exist out of the physics
of the current universe then it must be infinite and if that is true then the odds of anything that
could possibly happen would happen rises to 100 and that's where the paradox lies if anything that
can happen would happen there is a 100 chance of the entire universe becoming permanently
incapacitated freeze in a single frame and never move ahead the time's own ubiquity would kill it
and that's how the universe would come to an end as a still three-dimensional portrait of itself
but what if time does have an expiration date this question has boggled the minds of scientists
because time not having a limit should have broken the universe according to their calculations
coming up with a precise time barrier for our universe is hard because we don't know exactly the
boundaries of our entire universe however based on the calculations made with the observable universe
physics predicts that we would cross the time barrier somewhere in the next
3.7 billion years how does time ending abruptly affect the universe's demise
that we leave to your imagination
the last two theories insinuate that the universes are forever yes you heard
that right i said universes but let's talk first if there is just one eternal universe
this model was a widely accepted model till the 1930s when the big bang theory was discovered
however in the light of the big bounce theory this theory is having a sort of revival
and proposes that unlike the big bounce creating a new universe it is the same universe repeating its
cycle again and again yet physics supports the idea of a multiverse more it states that there
are multiple universes existing all at once and no matter what the number of new universes will
always outnumber the old ones so even if time ends in one universe it will carry on in another
i guess time does always win in the end tell us in the comments what you theorize
about how the universe will end and as always thanks for watching factnomenal
