Where black holes predicted to exist before they were found by astronomers?

Answer 1

Yes, they were. I believe thewy were theorized from Franz Zwichy of CalTech. They were originally called "nuetron stars", becuase they were believed to be formed when the gravity from a dying star crushed all the electrons right into the nucliae of its constituent atoms, causing the protons and electrons to "cancel out" and become nuetrons. Thus, you would get a tiny volume of pure nuetrons that was incredibly dense.

In fact, they're not sure if this really happens, but it probobly dosn't. When matter gets crushed down to those high densities, it forms what we now call a black hole, and because light cannot escape a black hole, we cn't tell what is happening inside it.

Answer 2

Considering that we have yet to find conclusive evidence of the existence of any black hole, then most definitely, yes. ^.^ There is, however, a large amount of indirect evidence of their existence, mostly in the observations of x-ray sources which match the profile of a black hole more than any other known or theoretical model.

Despite this, black holes are still theoretical in the strictest sense of the term in much the same way as gravitation, relativity, and quantum mechanics are theoretical. Everything we've observed so far (well... almost everything) adheres to these theories, but there is still always the tiny chance that they will be replaced in the future with a more complete, or even completely different, idea. (Example: Newton's gravitational theory being superceded by Einstein's relativistic curved spacetime.)

Answer 3

Yes black holes were predicted to have existed well before they were found by astronomers.

Answer 4

Yes! As a Matter of fact before they actually found what they suspected(hoped) was a black hole there is a going joke about something that Steven Hawking said. I forgot who was with him but the conversation went something like this... Steven Hawking: "I bet it's not a black hole" Unknown person: "What? You are one of the biggest supporters of the theory. How can you bet against it not being a black hole?" Steven Hawking: "Well if it's not a black hole, I win the bet; if it IS a black hole it will only mean that I've been right all along."

Answer 5

Yes.

They were first predicted by the English astronomer and clergyman John Michell in 1784. Thats right, 1784. He called them "dark stars". The name Dark Star was adopted by a cult sci fi film 200 years later.

Answer 6

yes, ands they have been predicted by Steven Hawking when he reversed I think it was Roger Penrose's equations for the big bang and it held so the black hole theory was born. Oh yeah it was a funny joke he bet a magazine subscription. He said it somewhere in a brief history of time I'll check...

Answer 7

Of course, mathematics has a sort of loophole for this, since the beginning of math and astrology. I believe Einstein left a hole for this, simply because he couldn't find a way to explain it to the rest of the world, his theories suggest it.
