the big bang theory till date is our best guess at how the universe truly began and
has been widely accepted as the starting point of everything we know the beginning of our universe
sure has an interesting story but since we weren't really there to see it it remains a huge mystery
welcome the Factnomenal and in today's video we take a closer look into some mind-blowing facts
about the big bang that could forever change your mind about the universe's origin story
there never was a bang well to begin with perhaps the biggest misconception of all
is that there wasn't ever really a bang or at least not in the common definition
the name big bang gives you the picture of fire explosions or something along those lines but
in reality there was no bang at all it was simply a vast expansion of extremely condensed material
the misleading name was actually given to mock the theory sir fred hoyle was the one to snidely
refer to the theory as the big bang with the intention of pointing out how absolutely absurd
the whole idea sounded funnily enough the name stuck he was of the belief that contrary to the
big bang theory the universe itself did not have a beginning but rather the components inside it did
discovered by a catholic priest the big bang theory was actually first put forth by none other
than a catholic priest perhaps the last person you'd ever expect to hear being associated with
a widely debated theory like the big bang belgian priests and astrophysicist father george lemaire
lemaire not only had a deep curiosity about the world beyond our planet and the deep unknown
but also a reverence for the creator of it all
he spent years of his life researching and expanding his knowledge on the subject
and in 1927 he revealed his innovative idea that our universe could be expanding
a theory called hubble's law that hubble himself hadn't even discovered yet at that point in time
his theory was mocked ridiculed and widely rejected for the most part two years later hubble
discovered the same thing and in 1929 his findings were published and the rest well that's history
and father george lemaire will forever be known as the father of the big bang theory
einstein was against it not everyone was a fan of the big bang and when the theory initially
emerged in the 1920s einstein was opposed to it he even infamously wrote to lemire saying
your calculations are correct but your physics is abominable but soon after american astronomer
edwin hubble found that the old steady state view of the cosmos where it was static and
always one size was wrong as a matter of fact hubble found that the universe was expanding
and actually getting bigger which has to have meant that at some point the universe started off
much smaller this of course blew up in einstein's face and he was forced to rethink his own model
of a static universe he mainly rejected the big bang because of the fundamental philosophical
problem that arises what came before however he would soon through his own research as well
see reason you can see the big bang when the big bang took place it marked the beginning of
everything we know and see today but the question is if we cannot actually see how this happened
how could we possibly have any clue about something that supposedly happened so long
ago after the big bang the entire universe was flooded with incredibly bright light a
microwave telescope can actually see this ancient light from the very beginning of the universe
if you were to look through a microwave telescope it would show you the whole sky filled with a glow
day and night this glow is called the cosmic wave background looking into space is like looking back
in time at the light we see because light from objects far away takes a long time to reach us
as compared to the ones closer to us in short the cosmic microwave background radiation is
the actual leftover radiation from the big bang as the universe's first ever radiation
occurred 380 000 years after the big bang its thermal proof remained frozen in time
the big bang happened everywhere contrary to the belief that the big bang was a massive explosion
that set everything into motion and was the beginning of our universe the theory actually
suggests that our universe was once much smaller than it is today and is gradually expanding and
hasn't stopped ever since which leads us to the question where exactly did the big bang take place
the universe itself has no center or edge and every part of the cosmos is expanding if we
turn back the clock we can figure out exactly when everything was packed together nearly 14
billion years ago because every place that we can map out today in the universe is occupied
by the same place 14 000 years ago there wasn't a specific location where the big bang took place
it happened everywhere simultaneously the hottest moment the big bang was the ultimate
extreme that we've ever known at the time of its occurrence the entire universe was jammed into an
infinitely small space the temperatures were soaring the temperatures at that exact moment
have been said to be so ridiculously high that there is actually no number of values developed
that we can actually use to even describe it which means if everything hadn't been uniform
and just right at the time of the big bang our fate could have been entirely different
life before the big bang while some may consider the big bang as the starting point and creation
of everything the theory also brought along with itself a lot of philosophical questions
the biggest of them all being that's indeed the universe is expanding and growing
what was it like before the big bang was there life and what happened some scientists strongly
believe that the entire early universe 2 could have been one large habitable zone at some point
after the death of the first stars life could have easily arisen some planets could have even hosted
microbial life forms some 15 million years after the big bang but what was before that
it looks like that's a secret the universe might just be keeping to itself
since we were not there to actually see it and the cosmic wave background doesn't exactly equal time
travel it's all speculation explaining hydrogen and helium the big bang theory was a revolutionary
idea that has given us some of the answers that we so desperately needed in our efforts to understand
more about our universe and the worlds beyond but one extremely notable contribution of the
big bang theory is that it is actually able to explain the existence of hydrogen and helium
back in the 1940s ralph alpher and george gemmell claimed that the early universe was hot and dense
enough to make virtually all helium lithium and deuterium present in the cosmos as we know it
known as the big bang nucleosynthesis which stands till today as one of the most successful
predictions of the theory without it we'd still be left guessing where all this hydrogen and helium
even came from afterglow or bird poop in 1964 scientists arno penzias and bob wilson were
working at the holmdel horn antenna at bell labs where they discovered a uniform radio
signal coming from everywhere in the sky at once they immediately assumed it was a problem with the
antenna and tried to get rid of the noise but the said noise was actually big bang's leftover glow
as they tried to calibrate the noise away they went to check the antenna and were
highly annoyed to find the nest of pigeons living there they thought the weird signals they had been
receiving were a result of the menacing pigeons and their droppings which they also had to clean
but once they cleared out the nests and droppings they realized the signal
did not go away but persisted it was then that they realized what they had actually discovered
inside a black hole space is no stranger to some really spooky and weird stuff but till date
black holes have got to be the most mind-boggling and terrifying objects out there like black holes
considering how little we know about them and how greedy all-consuming and destructive they are
black holes are still shrouded in mystery some new theories even provide supporting
mathematical proof that our universe as we know it is just living and expanding inside a black hole
the thought alone is enough to send chills up one's back so what are some crazy facts you
