What if Black and White hole met

you already know about black holes giant

space vacuums that pull inside

everything in their way but have you

ever heard of a space phenomenon called

white holes and what would happen if

these two met and let's say

collided let's hop on a shuttle Venture

into space and get to know them better

first as you already know you can't see

black holes directly even with fancy

telescopes that detect light x-rays or

other types of electromagnetic

radiation but we can see what a black

hole does to the things that surround it

for example when a black hole passes

through a cloud of space matter it pulls

everything towards itself in a process

called

accretion as the matter is pulled in it

becomes hot and emits detectable

x-rays or something else can happen

sometimes a regular star comes too close

to a black hole and gets torn apart a

black hole is a super dense object with

an incredibly strong gravitational pull

that starts stretching the poor star out

into a long and thin shape like

spaghetti you probably guessed it we

call this

spaghettification as the pieces of the

star are pulled in they become hot and

emit x-rays a black hole can choose a

different method too squishing the star

and making it flat like a

pancake in the other corner you have a

mysterious white hole these are less

well known because we don't have much

information about them our knowledge of

white holes is based on theories derived

from the same mathematical equations

used to describe black

holes to witness this battle you would

need to get close to a white hole but

don't worry at least this one won't eat

you and turn you into spaghetti or a

pancake

just like nothing can escape a black

hole nothing can enter a white hole it's

like the most exclusive Club in space

with no entry

allowed you can see that white hole also

has a mass and even spin there might be

a ring of dust and gas around its Outer

Edge known as The Event Horizon which

acts as a border separating the white

hole from the rest of the

universe while they share similari ities

there is one crucial difference a white

hole can release matter and energy while

a black hole

cannot scientists describe a white hole

as the time reversal of a black hole as

if you're watching a video of a black

hole played

backwards things that are already inside

a white hole can leave and interact with

the outside world however nothing from

outside space can ever affect the

secretive inner world of a white hole

Einstein said that space and time are

not flat they can bend and fold all

because things like stars and planets

have mass a scientist named Carl Schwarz

child figured out how to use Einstein's

ideas to describe what happens around a

really heavy object he discovered

something called a

singularity it's a point of infinite

density and it lies at the center of a

black hole it's like a tiny tiny point

where everything is squished together

all the matter that the black hole has

consumed the tricky part is that the

singularity is so small that it doesn't

really make sense in our normal

understanding of time and space plus it

bends space around it so much that it

creates a special area that's cut off

from the rest of the universe we call

this area a No Man's Land which is

basically where black holes

exist scientists still can't understand

what happens at the point of singularity

in black holes let alone white

holes so let's go back to the questions

we started the story with what's

stronger and what would win then it

seems black and white holes have

completely different strategies a white

hole is a mystery that we still don't

know much about but it seems more

experienced at conquering space than a

black hole is I mean a black hole

swallows matter and everything it

encounters true but a theory suggests

that white holes may have once been

black

holes they're purely imaginary for now

but stories say white holes can only

exist if there is absolutely no matter

inside their boundaries if even the

smallest particle entered a white hole

it would cause it to collapse

that's a significant disadvantage in a

potential battle don't you think but

it's also a really tough task to try to

sneak a small asteroid inside a white

hole its gravity is most likely

extremely powerful and will push you

away this is where the singularity comes

into play remember when I said

scientists were not sure what really

happens with this tiny tiny dot of

infinite density it can't be that a

black hole just infinitely collects

matter in its Center something else has

to be happening

there H what if this Singularity kind of

rebounds and actually becomes a white

hole of course it would take a really

long time for this to happen like

billions of years even for the smallest

black

holes there's a special type called

primordial black holes and scientists

think those probably formed right after

the universe was born and if there were

really tiny black holes created after

the big bang they might have already

exploded and turned into white

holes some scientists even think white

holes could possibly explain the Big

Bang since both involve an enormous

amount of matter and energy appearing

out of nowhere all this doesn't sound

promising for a black hole can this be

the first time ever it's going to lose

if a black hole becomes a white hole it

doesn't even matter how much it's

consumed it might throw everything back

out into space in that case a white hole

might not last that long so it will need

to make a move against its opponent

really

quickly W you may have thought you were

safer near the white hole because it

wasn't about to eat you but look at it

it's shaking oh no it started ejecting

all the things at been keeping inside at

the speed of light get out of the way to

not have some ripped Planet catapulted

in your

direction after Millions even billions

of years of making a mess all around the

universe a magnificent spectacular and

chaotic battle is about to start the

black hole is patiently taking the

attack pulling in everything that the

white hole is throwing in its direction

asteroids all those ripped stars that

used to shine so brightly in the night

sky planets and even entire galaxies

it's all getting out of it insanely fast

and in all

directions both the white and black hole

have managed to survive against every

space object till now but that's just

because they haven't faced each other

yet it's an exhausting battle that

doesn't stop All Odds were against the

black hole at the beginning but look it

seems something is changing the white

hole is slowly losing energy since it

can't swallow any new things and renew

its

supplies meanwhile the black hole is

patiently collecting everything its

opponent has thrown at it during this

Fierce attack growing bigger and bigger

it can keep doing it for thousands of

years its insanely strong gravity brings

the white hole closer even though it's

trying to

escape and the time comes for the last

strike the black hole's gravity starts

stretching its enemy until it swallows

it entirely the white hole is completely

gone and now that it has so much energy

our winner is more massive and stronger

than ever oh no run now you have this

hungry super massive black hole

wandering around looking for more things

to eat until it falls apart into a white

hole again one day and starts an even

bigger more magnificent battle that the

entire universe will watch
