A blackhole is caused when a star implodes and collapses under it's own weight creating a super dense object which has an incredibly strong gravitational pull, so strong that nothing, not even light can escape from it.

So it doesn't really have an inside as such, and the outside is space and whatever cosmic debris happens to be caught in it's gravitational field.

Summat like that anyway

Many responders have said that a black hole is infinitely small. That is not correct.

The size of a black hole is usually expressed in terms of its "event horizon." For a black hole with a mass of 10 suns, the event horizon is about 30 km from the center. That means that such a black hole would be about 60 km (37 miles) across.

The significance of the event horizon is: once you cross over it, you can never go back out. For this reason, it's usually considered the "boundary" of the black hole.

For a black hole that small, the tidal forces would stretch you to spaghetti even before you got as close as the event horizon.

But for hugely gigantic black holes, the tidal forces near the event horizon are actually SMALLER than for little (60 km) black holes. This means: the larger the black hole, the GREATER your chances are of surviving a trip across the event horizon!

Most scientists feel that, if you were to fall into a very large black hole (one with low tidal forces), you probably would not notice anything particular out of the ordinary. However you would have permanently lost contact with the outside.

A black hole is formed when a large amount of energy of a star gets concentrated on a small area. As known it has a great gravitational force but what is actually within the black hole is not yet known by the scientists but outside it has 2 be darkness and emptiness because it has such strong gravitational force that even light cannot escape it.

black hole is avery dense area having a very high gravitational force. even light cannot escape it. so it suspected that there is a body that creates a very high gravitational field in and around it. outside the blackhole there are gases which tend to move t the centre of the blackhole. they are viewed to be spiral in shape and the temp. of thhe gases are extremely high.

Outside of the event horizon, is hot gas shaped like a disk. Below, I imagine it like a vast tunnel lit by the gas pouring in around you. Near the end, would be a black dot shaped like a fractal (maybe?). On the surface, it looks like a bumpy orb. Inside, is the pure state of energy, the lowest state which matter can reach. But it should not be constrained to one point in space, as our minds would lead us to believe. The energy is distributed across the quantum. This is permitted by the Zero Law of Thermodynamics, emphasizing the equality of heat. The rest is conjecture based on principles.

The Universe itself is probably a black hole. If it is not, the Universe is outside all black holes, what is inside is a point of infinite density. Since the known facts of physics do not apply at infinite density, that is the only description that can be made at this time.

there is no 'other side' of a black hole as most people think. there is just the center. there is an infinitely small, massive, and dense point. witch gravity so strong that before you reached the black hole the tidal forces would rip you apart, and then once you reached the center you would be compressed in a single point. there you (or what made you, you'd be dead) will stay for billions of years, until all of the mass of the black hole is lost in whats known as hawking radiation.

there is much that we dont no about the inside of a black hole. however scientists have agreed that the farther you go into a black hole the closer and deser things get eventually reaching singularity. Im not sure exactly wat that is but i think it deals with everything becoming one with each other. all atoms are compressed together to form one thing. The outside is just space and the gravatic vortex that grabs things.

A dense dark planet on the inside. High gravity pulling in everything including light on the outsde.

in the inside of a black hole there is a sun that imploded due to the gravitational force caused by all that mass. and it may also contain planets and moons that were sucked into it and then crushed beyond all reconition.
