At Long Last, a Glimpse of a Black Hole

Gravity is not an attraction. It's caused by massive objects warping spacetime.

That's another way of describing it.

My point is that gravitation isn't a thing, it's a phenomenon. It just is its effects.

I don't think we have any evidence to support that view. The first law of chemistry & physics: matter can neither be created no destroyed. The Einstein E=mc^2 equation that gave rise to nuclear energy is an obvious exception, matter being converted directly into energy. I believe that the gravitational & magnetic forces inside the black hole renders matter into a plasma of fundamental atomic particles & gamma (X) rays. If we can identify such a source via astronomy a case could be made that we're looking at the 'other' side of a black hole existing either in an alternative universe or elsewhere in our own. Only a special probe could determine whether or not this was true.

I really can't give a credible opinion here. It's because I believe the laws of physics within a black hole are likely different than that outside. It's similar to trying to explain the physics in the initial moment of the big bang. Or like trying to understand the physics of the singularity that produced the big bang.

We've gone from Newtonian Mechanics, to Quantum Mechanics, to Relativity. And every leaped forward negated much of the rules previously in place. So who knows how many more leaps we may make, before we understand the physics of a black hole? I surely can't render a guess!

There's no reason to think conversation of total mass-energy would be violated in a black hole. Conversation of mass-energy isn't violated in either General Relativity or Quantum Mechanics. There's also no reason to think that black holes are a "portal" to anything. That's a creation of science fiction. Also, mass and energy are interchangeable, they're governed by a constant relation (E=mc^2), so they are just different ways of describing the same phenomenon. It's not possible for energy to exist apart from matter.

If you have an interest in the subject then I recommend reading Reality Is Not What It Seems by Carlo Rovelli. The first half of the book provides a good overview of human understanding of these things from antiquity to present with the later half dedicated to explaining loop quantum gravity.

Thanks for the recommendation. Along with science, I enjoy history and reading about the history of scientific processes that got us here. So this looks like an interesting book to check-out.

Read about the Haber process in Germany & how it resulted in decimation of the huge saltpeter industry in Chile. Everything in the world is connected.

I was really into black holes awhile back, when the were a relatively newer phenomenon to the general public. And like many, I was fascinated by them. But I never did get much into string theory, besides having a higher-level understanding of the basic concept.

Once you go black..............:lamo


Sorry, no discipline this afternoon....
 
Some physicists believe that black holes are flat 2-dimensional objects which create the illusion of a three dimensional sphere.

Black hole geometry: flat it's not, 3-D it is.
