What If a White Hole and Black Hole Collided?

[Music]

black holes are one of the most

devastating objects in space sucking up

everything around them but there's

another space phenomenon that's just as

destructive and it's known as a white

hole now what would happen if these two

objects met in space and fought each

other could something like this even

happen who would win and what is a white

hole anyway this is what if and here's

what would happen if a white hole fought

a black hole before we get to our fight

let's see what these two opponents are

all about in one corner of space we have

the black hole this legendary space

occurrence is probably pretty familiar

to you it's signature move is to consume

every piece of matter it comes in

contact with the white hole you're

probably less familiar with and it's

signature move is to expel energy rather

than sucking it in so with our two

fighters having completely opposite

attack strategies who would win despite

us not knowing much about our white hole

mystery opponent it's much more

experienced at conquering space than the

black hole is that's right the white

hole is a proper journeyman and has been

roaming space for millions of years

kicking butt and taking names that's

because scientists theorized that this

white hole used to be a black hole

scientists suspect that after millions

of years black holes will become white

holes and all the energy and matter they

consumed over the years will be expelled

back into space that being said when a

black hole becomes a white hole it might

not last very long so it will need to

act quickly if it wants to pick a fight

with a black hole and despite it being

different the white hole is just as

destructive as a black hole if not more

so the matter the white hole is ejecting

moves at the speed of light so it's safe

to say that the white hole is the

veteran fighter in this situation as

opposed to this up-and-coming black hole

but how much will its experience help it

after millions of years of causing

destruction throughout the universe our

two opponents finally meet they've

battled asteroids planets and even stars

but they always managed to survive now

they both face their greatest opponent

yet as these two massive forces approach

each other the black hole will instantly

gain the advantage the white hole will

do its best to prevent the black hole

from overtaking it but unfortunately it

really doesn't stand a chance that's

because the white hole has no choice but

to spit energy at its opponent although

it was able to defend itself against

everything else in the universe

unfortunately the black hole is its one

true match the mass the white hole is

expelling is also being turned into

energy for the black hole

this won't be a quick battle either as

the black hole can feed on the white

hole for thousands of years and as it

keeps feeding the black hole is getting

larger and larger and now the black hole

is ready for the finishing blow it

completely swallows the white hole now

that it's consumed so much energy how if

black hole is more massive than ever it

might be as big as the Messier 87 which

is 38 billion kilometers across

for reference that's three million times

larger than Earth so if a white hole and

the black hole collided we'd have a

massive black hole roaming around the

universe destroying everything in its

path

[Music]

and if it were anywhere near us well

that would mean humanity would be in

some pretty big trouble but we'll leave

that story for another what if
