Stephen Hawking Suggests Black Holes Are Possible Portals To Another Universe (scienceworldreport.com)

An anonymous reader shares an article on Science World Report: Stephen Hawking, in a recent lecture held at the Harvard University, claimed that black holes could be portals to a parallel universe. The celebrated physicist spoke at length about black holes and suggested that they neither store materials absorbed by them nor physical information about the object that created them. Known as the information paradox, the theory goes against the scientific rule that information on a system belonging to a particular time can be used to understand its state at a different time. Over the years, it has been speculated that black holes do not retain information about the stars from which they are formed, except storing their electrical charge, angular momentum and mass. According to Hawking, as per that theory, it was believed that identical black holes might be formed by an infinite quantity of matter configurations. However, quantum mechanics has signaled the opposite by revealing that black holes could only be formed by particles with explicit wavelengths. If the characteristics of the bodies that create black holes are not deprived, then they include a lot of information that is not revealed to the outside world, according to the physicist. "For more than 200 years, we have believed in the science of determinism, that is that the laws of science determine the evolution of the universe" Stephen Hawking said. If information was lost in black holes, we wouldn't be able to predict the future because the black hole could emit any collection of particles."This is in contrast to some of Hawking's earlier views. In 2014, for instance, Hawking suggested that black holes don't exist, at least not like we think.

Not quite logical

If the mass completely leaves the universe for another universe, why would the gravity be left behind? Also we still can't retrieve the information about the matter that entered without leaving this universe. Also, black holes from other universes should perhaps then spew random massive particles into our universe somewhere and we wouldn't be able to use its vector to determine where it came from AND it would start interacting with matter in our universe which would mess with the back-tracking of information on movement. So much for information preservation.

"If the mass completely leaves the universe for another universe, why would the gravity be left behind?"

I wondered something similar when they kept saying the singularity in a black hole has zero size. Well something with no dimentions doesn't exist so how can it still have a gravitational field? Unless because time is so slowed inside a black hole relative to outside that from an outside observers point of view the singularity essentially never forms.

Sphere of Annihilation

[Infiniti2000]

Going through a black hole will destroy you, much like a sphere of annihilation. This article reminds me of one of my favorite D&D stories. As relayed by another DM of a group of relatively inexperienced (new) players, they had encountered a sphere of annihilation. One player touched it and promptly vaporized into nothingness. One of the remaining party members said, "Oh, it must be a portal! Quick, everyone, jump in!" Four more pops later and the DM had to decide between a TPK or a new adventure in some otherworldly plane.

For Hawking, it's worth listening to his intuition even if he doesn't yet back it with science. It's not like he's some quack that has never made a solid discovery. Maybe he or someone else will take his ideas and put forth the work to reconcile them.

I agree that the press should never report his ideas as fact or even probable until there is an adequate basis for that claim. For now this needs to be classified as musings of Hawking, and that's all.

Re:Determinism?

[Flavianoep]

No, it was not determinism that quantum theory killed. Under Heisenberg's incorrectly named "principle of uncertainty," the exact position and momentum of a physical system cannot be measured a at the same time, but that doesn't mean they are undetermined, just that we cannot measure both of them at the same time. The term for it is Unschärferelation, that roughly translates as "unsharpness relationship", but due to Slashdot's lack of support of Unicode at the time, it was not possible to keep that in the original German, so the translation "principle of uncertainty" was adopted [source].
