arrived here and for 30 seconds it was astonishingly bright and i was thinking
okay when these black holes around they swallowed up all the stars and they're just sitting around
that's where photons literally move around the black hole and around that is this hot gas
it's drawn to the black hole and it's hot because of friction all this gas is trying to get into
a very small volume so it heats up there's an alternate description of a black hole in terms
of what's known as the holographic description it's as if there's a two-dimensional world
that surrounds any given three-dimensional world that has exactly the same physics as the
three-dimensional world that we're familiar with and yet it describes it in completely different
language the universe is infinite and so is the human curiosity to explore it such as our
gallantry that every big monster we found in space may it be neutron stars cannibalistic galaxies
or supermassive black holes have caused us to become curious sir to find the next big thing
astronomers believe white holes could be the next big thing that we will discover welcome to fact
nominal and let's find out what makes white holes more powerful and frightening than black holes
the celestial championship and those are typically gargantuan black holes millions
or billions of times the mass of the sun electrons don't like to be very close to each
other so it's called the power exclusion principle but essentially what happens
is that so as they get squashed closer and closer together they move faster and faster
since black holes first captivated the public imagination decades ago they have garnered a
certain reputation these goliaths have been labeled monstrous and destructive
bent on devouring anything that dares approach in space there is nothing that can escape them
nor that can beat them as far as we know they can be perceived as the cosmic waterfall where
the universe dumps all of space and time to never return interestingly even something as bizarre and
gargantuan as a supermassive black hole can be defined by numbers and equations there is
nothing in outer space that cannot be explained with good old mathematics as great as that may
sound it's also the reason why we sometimes have answers for questions we didn't even ask
after einstein introduced the world to general relativity in the early 1900s we were introduced
to the world ending space monsters of our galactic universe black holes as mathematics gave us the
reason to believe that black holes were real we ended up proving they do in fact exist
with this being true there was no reason we could simply ignore the other side of the equation
the white holes in mathematics every positive number has its negative counterpart every
numerator has its denominator and therefore the existence of a black hole means there should be
a white hole as well at their very literal core black holes and white holes are a
singularity created by an immense amount of mass condensing down into a small amount of space
this singularity then also creates an event horizon around it due to its inexplicable
gravitational pull here time and space bend and warp beyond our wildest imagination
theoretically the ingredients are identical to one another except for their direction of passage
what is the difference curious mathematical opposites of black holes and they were
discovered mathematically in i think was the early 1970s when black hole mathematics was
maturing on a hypothetical level a white hole would be the exact opposite of a black hole
a black hole is the result of a large dying star that collapses in upon itself
whilst the core of the star is imploding the outer layers are flung out into space
in the form of a supernova which can be described as a beautiful but violent cosmic explosion
the imploding core causes all the mass of the star to squeeze into a very small amount of space
known as a singularity as a result the gravitational pull of this former star
and now a black hole is so large that even lights the fastest thing in our universe cannot escape it
and that's why black holes are the darkest objects in the cosmos
conversely white holes as they are hypothesized to be the exact opposite are the brightest thing in
the sky they can be considered like a black hole in rewind they will be revolving in the opposite
direction spewing colossal chunks of matter and energy in space just like one cannot escape a
black hole's event horizon one would not be able to enter a white hole's event horizon
some physicists also believe that if a white hole would exist its core would have no mass this is
one of the main reasons why white holes are not considered to be real having no mass would mean
that white holes decrease entropy the second law of thermodynamics tells us that the overall
entropy of the universe is increasing therefore if white holes decrease entropy they would not
fit into our current model of the universe their existence would mean that perhaps we would have
to throw everything we know about the universe out the window on an interesting note though
if we ever found a white hole studying it could reveal the forbidden secrets of time travel as
to go back in the past one needs to decrease the entropy back to the moment you want to travel to
scientists suspect that after millions of years black holes will eventually become white holes
and all the energy and matter it consumed over the years will be expelled back into space that being
said when it becomes a white hole it might not last very long as a black hole expands
over time it's obvious to assume that a white hole would become smaller and smaller over time
given whitehole is truly contrasting in nature to the black hole the only commonality between two
gargantuan cosmic bodies is that the white hole will be just as destructive as the black hole if
not more so the matter the white hole is ejecting moves at the speed of light and that's the paradox
as far as we know matter can't move at the speed of light as it would require
an infinite amount of energy so if white holes do exist they would be powerhouses of creating
infinite energy which sounds extremely lucrative but it is extremely destructive as well because
this energy would be raw and untamed causing destruction to anything and everything in its path
now we know what you must be thinking could a white hole destroy a black hole
the collision of the eons so to settle this argument there is no better way but
to put the two colossi in front of each other and let them duke it out
as these two massive forces approached each other the black hole would instantly gain the advantage
the white hole would do its best to slow the black hole down by throwing everything it has
at the speed of light but here's the twist in a black hole's event horizon space and time
warps and sinks faster than the speed of light so black hole would gladly accept everything
soon the battle would become one-sided because the white hole has no other choice but to expel
all of its energy at its opponent and its only weapon is nothing but food for the black hole
the black hole will be able to feed on the white hole for eons turning the white hole's mass into
energy and as it keeps feeding the black hole will grow larger and larger eventually swallowing the
white hole completely but after it's consumed so much energy and is more massive than ever
would it truly be a black hole anymore if you have been watching this video closely you may
remember that scientists believe that at the end of their life cycle black holes become white holes
and what could be the end of life for a hungry monster that just keeps eating eating eating
surely there is a good chance that eating something as filling as a white hole would
be just enough to tip the scales and cause a black hole to explode and turn into a white hole so in
the end can we say that a black hole truly won the battle if it became its own worst enemy well
there is a possibility that it might not go down that way and that the black hole would just become
even more massive it could become as big as poehy the black hole at the center of messier 87 which
is 38 billion kilometers across for reference that 6.5 billion times more massive than the sun
however given that white holes currently only exist in mathematical equations
we don't have to worry about some universe shattering event and black holes can remain
the undisputed most powerful champion of the cosmos at least for now what do you think
will we find white holes in the universe one day like we have black holes or are white holes
too impossible to exist tell us in the comments and as always thanks for watching fact nominal
