What is the Multiverse, and why do we think it exists?
Posted by Andreas Matt in categories: cosmology, particle physics
Whether these Universes are similar or different to our own, whether they have the same physical laws and properties, whether they have the same fundamental constants, particles and interactions, we do not know.
And at the same time, our very best laws of nature tell us that this is reality: we are a tiny fraction of our observable Universe, which is a tiny bit of the unobservable Universe, which is just one of a tremendous number of Universes in a multiverse that’s constantly generating new ones, and has been for billions of years. And that’s the Multiverse we live in, to the best of our knowledge!

Stephen Hawking says Black Holes could be portals to another Universe
Posted by Andreas Matt in categories: cosmology, law enforcement
According to statements from renowned astrophysicist Stephen Hawking, Black Holes are not the cosmic prisons we thought they were, and could actually be portals to another universe.
During a lecture at Harvard’s Sanders Theater, renowned physicist Stephen Hawking helped about Black Holes during an event which marked the inauguration of Harvard’s Black Hole Initiative wich aims to join numerous scientists and focus scientifically on Black Hole Research.

New Model Could Show That Stephen Hawking Is Right About Black Holes
Posted by Andreas Matt in categories: cosmology, particle physics
One of the longest standing mysteries of black holes is what happens to stuff when it falls inside. Information can’t move faster than light, so it can’t escape a black hole, but we know that black holes shrink and evaporate over time, emitting Hawking radiation. This has troubled scientists for 40 years. Information can’t simply vanish.
Now, physicists Kamil Brádler and Chris Adami, from the University of Ottawa and Michigan State University respectively, have been able to show that the information is not at all lost, but is transferred from the black holes into the aforementioned Hawking radiation, potentially solving a long-standing mystery of cosmology.
Over 40 years ago, Stephen Hawking put forward the idea that although nothing can escape a black hole, there should be a certain amount of particles emitted from the outer edge of the black hole’s event horizon. This emission would over time steal energy from a black hole, causing it to evaporate and shrink.
