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? How could something like this happen? Who would win? And what is a white hole anyway?

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.


Its 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 will 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 theorize 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 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, 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 still 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 get 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 growing 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, our black hole is more massive than ever.

It might be as big as the Messier 87, which is 38 billion km (23.6 billion miles) across. For reference, that’s 3 million times larger than Earth. So if a white hole and black hole collided, we’d have a massive black hole roaming around the Universe, destroying everything in its path.
