What's your best theory about Black Holes?

There are a couple of interesting things that happen near a black hole. We know that they have gravity (warp spacetime) and can see the effects from perturbations of orbiting stars.

The amount of gravity is such that the escape velocity is more than the speed of light. The distance where the escape velocity equals the speed of light is called the event horizon (approximately 7 miles for each solar mass.)

As objects near the event horizon, they become compressed, tidal compression; they become stretched, tidal shredding; time appears to slow down for the object heading for the black hole and spontaneously seems to speed up for the object, spacetime dilation.

So if you were falling into a black hole feet first, you would become stretched out feet to head and compressed front to back and side to side, like a spaghetti noodle, spagetification.

If you could somehow survive long enough to see anything, you would see that time would speed up for everything else around you. Stars and planets would spin faster, orbits would increase in speed, etc. For everyone looking at you, you would appear to slow down.

I am not as sure about wormholes, but this is my best recollection:

Wormholes are part of the general theory of relativity, however they have not been proven to be real. From my understanding, GTof R has many solutions that are not real and need to be backed up by observation.

Sage has it pretty much right, and there are a lot of books about it. My favorite is by Prof Kip Thorne, called Black Holes and Time Warps. You can get it at the library or any book store.

A more interesting question is suggested by Sage, and it is: How can anything actually ever fall into a Black Hole? Given that time dilation increases as gravity does, and increases infinitely at the event horizon (recall how Sage said that the rest of the Universe would speed up relative to the thing falling into the Black Hole, well an object falling into a Black Hole observed from a distance appears to age/move more and more slowly and appears to stop at the edge of a B H), so from either perspective, the thing cannot enter the B H (cross the event horizon)> Either it never quite does, or the Universe passes out of existence.

Either way it doesn't happen.

Contemplate this, a black hole forms from a collapsed massive star but the gravity of the black hole must be less than that the star it formed from because some of that star's mass was blown away in the super nova explosion, the black hole has an event horizon, the star did not. General relativity claims that a great mass warps space and light follows the curved space. It occurred to me that perhaps light follows a gravitational field, the black hole's gravitational field is different from that the star because it is limited to a tiny area of space and it offers a perfect path for light to follow. Gravity has confounded science for centuries, it needs more investigation.

Black Holes are where gravity is so dense that that is just about what a Black Hole is: "gravity"! Nothing can escape from it, not even light due directly to the effect of gravity, + It could have been proven, by now, however, it is thought that a black hole is different from a wormhole because a wormhole is used to travel byond the place where it is, & therefore, a wormhole can move. Where as a black hole doesn't move, or so it is thought.

A black hole is what you get when a super giant star reaches the end of it's life and collapse in on it's self, leaning a much smaller object but one spoon full will weigh thousands of tons.

The universe is a singularity - an infinitesimally small dimensionless point. Within our singularity universe there are really only two separate entities; static matter and continuously expanding time and space.

All the matter (m) in the universe is static and unchanging. As time and space (c) continuously expands around matter, it must curve out of its way and we experience this as an acceleration called gravity. Also within the singularity is the subatomic phenomenon called energy (E), but this is just static matter (m) directly conflicting with the continuously expanding time and space (c) and this interaction is expressed as E=mc^2.

A Black Hole occurs when mass (m) accumulates in such a compressed state that time and space (c) are infinitely curved around it and excluded.

A Black Hole has no time or space to be a wormhole and they are not observed to change their mass as a wormhole would indicate.

If you came close to a black hole, you would be crushed to an infinitely small ball of matter.

I think close to black holes, light appears squished and slow.

Wow! Cool question. Scientists claim to have all the skinny on black holes now, but I digress. My favorite and most sensible theory is the one that suggests black holes can appear out of nowhere. The milky way actually has one! Black holes are made of Dark Matter. One atom of dark matter is more dense than any other known substance. I don't claim to know, I just like to study on these things. Didn't google this, so excuse the incorrections.

General relativity, but i'm afraid that "lone wolf" is incredibly misinformed.
