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.

    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.

      I am not an astrophysicist but i thought the reason a black hole would still have mass and gravitation is that not only is the mass compressed to a geometric point but the resulting gravitation that causes time to appear to effectively stop also compresses the space that contains it.

      Basically that if you could be an observer within the geometric point the amount of space within that point would be near infinite and the surrounding space outside that point would be unobservable.

      Sounds like our universe to me. It's a lot better than that BS "we may be a simulation" that was floated here a few days ago.

  3. least plausible by ooloorie · · Score: 4, Interesting

    "Portals to another universe" sounds like the least plausible model of black holes. More plausible are non-singular models in which the matter simply transitions into another state inside the black hole; examples are the gravastar and the dark energy star; there are many other possibilities.

    It also seems odd to me that people would cling to the "information paradox" as if there were some good reason to believe it. If you truly believe that there is a singularity at the center of a black hole, why wouldn't you also believe that it can destroy information? Conversely, if you try to preserve information in a black hole, it seems to me that you are effectively already modeling an object other than a singularity.
