This would keep the throat of the wormhole stable, while also preventing it from collapsing. Exotic matter has negative mass and positive surface pressure. Though you might at least get to see some distorted light from the parallel universe on the other side.īut since this is mostly theoretical, there are always theoretical solutions, like using exotic matter to stabilize a wormhole. It would also be impossible, with physics as we know it, for one to pass through a wormhole into another universe (also theoretical) due to a number of pesky things like being spaghettified when passing through a black hole’s event horizon before being compressed at the singularity.
Unforunately, these wormholes would be highly unstable if they were even possible. The aforementioned Schwarzchild geometry implies that a wormhole would connect a black hole and white hole with two distinct universes connected at their horizons, also known as an Einstein-Rosen bridge. So, if a black hole is sucking in all of this information and a white hole is spitting it out somewhere, mustn’t there be something connecting the two? A wormhole perhaps? Maybe.
But it depends on how one looks at entropy, with some physicists saying it refers to disorder, while others say it refers to information used to describe a system, and an argument over semantics ensues. Many argue, however, that white holes are theoretically impossible because they violate the second law of thermodynamics, stating that entropy cannot decrease in a system. This is referred to as quantum bounce, a rebound from a black hole ingesting everything into a white hole expelling everything. So, in the case of black holes, these incredibly finite loops would prevent a collapse into infinity, but eventually the loops would only be able to compress to a certain point, until they exert an outward pressure, almost like a spring. To a viewer these loops would be make space-time appear to be smooth and continuous, but their granular nature would prevent highly dense bodies like neutron stars from collapsing into a point of infinite density. This quantification comes in the form of loops, almost like little threads that are of a finite size – so finite they cannot be subdivided any further. The premise of white holes is based on a theory positing that space-time is made of granular building blocks that can be quantified. They believe it’s possible that at the moment of creation, everything was expelled from a massive white hole on an incredibly large scale. Physicists also believe this concept could be germane when talking about the big bang and how our universe came into existence. This would obviously make a white hole incredibly bright, and some quantum physicists believe that maybe some of the light in the universe we thought was coming from supernovae, may actually be from white holes.
Light cannot escape a black hole, so light cannot enter a white hole. Just like the color black is the opposite of white, the white hole is the opposite of a black hole in every way. This is fundamentally part of what’s known as Schwarzchild geometry, the formulae used in general relativity to describe the gravitational field outside a spherical mass. One way to conceptualize this in a very basic mathematical sense is to think about the square root of 9. But is it really possible that white holes exist? So theoretically, if information is getting sucked in, it must be getting spat back out somewhere, and likely that’s through a white hole. With the no-hiding theorem, if information is missing from one system, then it must simply be residing somewhere else in the universe – a cosmic game of hide-and-seek. If it evaporates, what happens to all of the information it sucked in? If quantum theory is correct, this would defy a fundamental law that information cannot be lost – it’s called the no-hiding theorem. When Stephen Hawking proposed the idea that a black hole will eventually evaporate by leaking radiation from its event horizon, there was a problem.
