Why Finding White Holes Might Just Be The Biggest Answer To One Of The Physics Debates

Let’s to talk about blackhole’s weird twin, white holes. Basically, a white hole is the hypothetical opposite of a black hole. Now will bet that you know what a black hole

is, but hey, they still have to explain seat belts every time you fly on an airplane, so buckle up because after the refresher we are going on a wild ride.

Black holes are regions of space where so much mass is packed together so densely it forms what is called a singularity, and nothing can move fast enough to escape its gravitational pull. Not even the fastest thing in the universe, light can escape its clutches.

But you knew that right?

Everybody knows what a black hole is except that nobody knows what a black hole looks like, not EXACTLY anyway. Because of that pesky fact that light can not escape the horizons and we can not see what’s going on inside a black hole.

So we have to rely on theories and equations to deduce what’s happening at the center of the event horizon, and that has been a major sticking point in physics.

There are two competing explanations to describe black holes.

One of them is Einstein’s theory of general relativity, where

the mass of a black hole bends spacetime so much that it becomes one single point of infinite density.

On the other hand, according to quantum mechanics

There can not be an infinitely small point. It can be very very small, but not infinitely so.

And this irreconcilable difference is one of the greatest debates in physics, since general relativity is our best description of gravity, while quantum mechanics has been called the most successful theory ever. But some physicists believe white holes could square these two predictions and reveal what’s happening inside a black hole.

The equations of general relativity allow for the possibility of white holes, all you have to do is set the mass of the singularity to zero and everything gets turned on its ear. Instead of a cosmic vacuum that sucks up everything that strays too close,

you get about whatever the opposite of a vacuum is?

I’m not good with metaphors, but the point is all it can do is spew stuff out.

But then the question is, how do you get a singularity, a point of infinite density. Remember, with no mass? And how does a mass-less singularity spit anything out? Because of that head scratcher white holes have long been written off as a mathematical quirk but not something that can happen in reality.

However, quantum mechanics allows for some adjustments to the solutions of the equations of general relativity, and with those adjustments, the interior of a blackhole could transform into a white hole.

One physicist describes it as

though the curved spacetime of the black hole itself is bouncing out again

and this rebound opens up some tantalizing possibilities. Since a black hole might transform into a white hole, that means things falling into it may come out again.

This would solve another issue quantum physics has with black holes because in quantum physics information cannot be destroyed. Granted, whatever came out of a white hole would be a very mangled version of its former self, but nonetheless, information about what it would not be deleted from the universe. It sounds like a wormhole, but instead of traveling through space, the object would travel through time.

General relativity tells us that time moves more slowly near massive objects, so to an object falling into the black hole it would seem like very little time is passing, but to an outside observer, it would take ages to pop out again on the rebound.

Just how far into the future it travels depends on the size of the black hole, with big holes taking quadrillions of times the age of the universe to transition.

But small black holes that formed just after the chaos of the Big Bang may have already converted. They would be invisible because they would be smaller than the wavelength of light, but have a mass of about a millionth of a gram. White hole proponents say this could make them an attractive candidate for dark matter. Yeah, the upsides of white holes just keep getting better and better.

I have to remind you that white holes are still purely hypothetical. The math checks out and the reasons to hunt for them are numerous, but at this stage they remain a very unexplored corner of physics. Then again, there was a time when the same could be said about black holes. We are just going to need a few physicists dedicated enough to the idea of white holes to keep searching for them. That or a few brave volunteers to jump into a black hole. huh? who’s going with me, huh? Anyone?…Anyone? 👋😍

White holes may form faster when the black holes are less massive, but black holes themselves can merge and get bigger.

Alright, so I mean it. Who’s jumping in with me huh?! Who’s going in the nearest black hole?!👋🥲
