Black Holes are ‘Portals to Other Universes’.


Black holes are ‘portals to other universes’, according to new quantum results.

According to Albert Einstein’s theory of general relativity, black holes are uninhabitable chasms of space-time that end in a “singularity,” or a mass of infinite density. It’s a place so bleak that even the laws of physics break down there. But what if black holes aren’t so forbidding? What if they are instead some kind of intergalactic stargate, or maybe even a passageway into a whole other universe?
It may sound like the premise for a clever science-fiction movie, but new calculations by quantum physicists now suggest that the stargate idea might actually be the better theory. According to the startling new results, black holes do not culminate in a singularity. Rather, they represent “portals to other universes,” reports New Scientist.
This new theory is based on a concept known as ‘loop quantum gravity’ (or LQG). It was first formulated as a way of merging standard quantum mechanics and standard general relativity, in order to remedy incompatibilities between the two fields. Basically, LQG proposes that spacetime is granular, or atomic, in nature; It is made up of miniscule, indivisible chunks about the same size as the Planck length — which roughly amounts to 10-35 meters in size.
Researchers Jorge Pullin from Lousiana State University, and Rodolfo Gambini from the University of the Republic in Montevideo, Uruguay, crunched the numbers to see what would happen inside a black hole under the parameters of LQG. What they found was far different from what happens according to general relativity alone: there was no singularity. Instead, just as the black hole began to squeeze tight, it suddenly loosened its grip again, as if a door was being opened.
It might help to conceptualize exactly what this means if you imagine yourself traveling into a black hole. Under general relativity, falling into a black hole is, in some ways, much like falling into a very deep pit that has a bottom, only instead of hitting the bottom, you get pressed into a single point — a singularity — of infinite density. With both the deep pit and the black hole, there is no “other side.” The bottom stops your fall through the pit, and the singularity “stops” your fall through the black hole (or at least, at the singularity it no longer makes sense to say you’re “falling”).
Your experience would be much different traveling into a black hole according to LQG, however. At first you might not notice the difference: gravity would increase rapidly. But just as you were nearing what ought to be the black hole’s core — just as you’re expecting to be squashed into the singularity — gravity would instead begin to decrease. It would be as if you were swallowed, only to be spit out on the other side.

  1. This article would very much catch my son’s attention! He likes science, Einstein, the theory of the black holes…and like it says in the article, what if???…they were just star gate to other universe…imagine Ralphie, maybe then I would feel sometimes more ”at home”! Lol! Take care my friend, big warm hugs even though it’s cold out here!

    1. You know I can be quite thick when it comes to science and expecially maths is above me, but I came to all these new-fangled notions before they were published, just using a zen state, where everything is possible in multiple universes. I go into deep trances sometimes and I love it there.

      1. Yeah, I understand your ”trances”! I agree with you, it can be very nice up there, loving and comfy! Well, I’m not much into science myself…but I know there are things bigger than we see or even imagine…and I figured your kind ”zentitude (zen attitude!). Big hugs again Ralphie, be safe…and good, lol!
