Stephen Hawking does it again – black holes and transportation to a new universe
I don’t know about you, but I think this is the amazing stuff that science is really made of. Observe, make educated guesses based on that and then postulate a theory supportive of those observations.
That is what Stephen Hawking has done over and over again. Never mind that he is wheel chair bound and reliant on assistants to help him. It matters not.
What is important is the thought process, and Stephen Hawking has had that going for him for years.
So what happens when we get close to a black hole? Some say we get torn to shreds. Some say they don’t even exist. Others say (and rightfully so), our understanding of science does not tell us.
But Stephen Hawking says otherwise … he says we might enter another universe (aka another dimension).
Who is to say he’s wrong. And by the way, how bizarre is that?
I highly recommend the following two articles. After reading them, you might even have to rethink what you “know” about black holes all together …

Black holes are a passage to another universe, says Stephen Hawking
Humans could escape from black holes, rather than getting stuck in them, according to a new theory proposed by Stephen Hawking.
…… “The existence of alternative histories with black holes suggests this might be possible,” Hawking said, according to a report from Stockholm University. “The hole would need to be large and if it was rotating it might have a passage to another universe. But you couldn’t come back to our universe. So although I’m keen on space flight, I’m not going to try that.
Hawking’s proposal is an attempt to answer a problem that has tormented physicists about what happens to things when they go beyond the event horizon, where even light can’t get back. The information about the object has to be preserved, scientists believe, even if the thing itself is swallowed up — and that paradox has puzzled scientists for decades.
Now Hawking has proposed that the information is stored on the boundary, at the event horizon. That means that it never makes its way into the black hole, and so never needs to make its way out again either …

Hawking: Black holes store information
…… Physicists have long argued about what happens to information about the physical state of things that are swallowed up by black holes.
This information was thought to be destroyed, but it turned out that this violated laws of quantum physics.
Prof Hawking now says the information may not make it into the black hole at all, but is held on its boundary.
…… the laws of quantum mechanics dictate that everything in our world can be broken down into information, for example, a string of 1s and 0s. And according to those laws, this information should never disappear, not even if it gets sucked into a black hole.
But according to Einstein’s theory of general relativity, the information must be destroyed. This quandary is known as the information paradox.
Prof Hawking believes the information doesn’t make it inside the black hole at all.
“The information is not stored in the interior of the black hole as one might expect, but in its boundary – the event horizon,” he told a conference at the KTH Royal Institute of Technology in Stockholm, Sweden.
Hawking has been working with Cambridge colleague Prof Malcolm Perry and Harvard professor Andrew Strominger on the problem. They believe that information at the event horizon is transformed into a 2D hologram – a phenomenon known as a super translation.
…… On the question of matter getting stuck at the event horizon, she said: “Nobody really understands the details of how this happens – this is what Hawking is trying to work out and what other related ideas ‘fuzzball’ and ‘firewall’ explore too.”
There’s currently little additional detail on the maths behind Prof Hawking’s talk, but he and his collaborators plan to publish a scientific paper in coming weeks.
Light particles – or photons – can be emitted from black holes due to quantum fluctuations, a concept known as Hawking radiation. Information from the black hole might be able to escape via this route.
