i know black holes are made when stars die,but if stars die dont earth dies out some day also another question whats inside a black hole i always wondered is it some vortex that bring you galaxy's away?also why doesnt nasa send some robot to a black with a camera on it?

The gravity field surrounding a black hole is so intense that nobody knows what is inside one. If you get too close to a black hole, you'll be sucked into it, never to return to this universe.
The gravity is so strong that not even light can escape, so there is no point in sending a robot to take a picture -- there is, literally, nothing to see. Further complicating this, the nearest suspected black hole is very, very far away. It would take a robot spacecraft thousands of years to get there.

When stars that are much more massive than our Sun run out of fuel, the core collapses onto itself and the resilience of matter is not sufficient to stop the collapse.
For example, if you fall on the floor, the floor will stop you. If a 10 ton anvil falls on the floor, it may go through and will only stop when the Earth stops it.
Same thing with stars:
Stars like our sun will be held up by themselves: our Sun will become a white dwarf, then a red dwarf, etc. It will still be made up of atoms.
Stars that are a bit more massive: the mass of the collapsing stars will be sufficient to push the atoms together so strongly that the electrons will be shoved into the nuclei and merge with protons to form neutrons. These stars will become neutron stars where neutrons are squished one against the other. Such matter is very dense.
very massive stars: there is a point where nothing can stop the matter from collapsing on itself, not even the "degeneracy pressure" of neutrons or even quarks. The result is what we call a "stellar-size" black hole. All the mass collapses to a volume of zero (called a "singularity")
There are also very big black holes at the centre of some galaxies. These may have been formed as part of the process by which the galaxy was formed. Our Milky Way Galaxy has one, with smaller black holes orbiting it (see the APOD web site: there is a picture that NASA helped with).
We do not know if there are any black holes closer to us. The closest one we know for sure is at the centre of the galaxy (almost 25,000 light years away).
If we were to send out a probe at 1,000 km/s (which would be a new speed record for probes) it would take quite a few trillion years to get there (and then another 25,000 years for the images to come back).

The earth is not a star and therefore will not "die out." We will be consumed by the sun as it expands burning hydrogen into helium. As for whats inside a blackhole, well no one has ever been inside one or seen inside one so all the answers you recieve here can (and probably will be) contractidicted. The nearest black hole is light years away in the middle of some stars, maybe because we don't have the technology to power a camera or have control or it via remote from that distance. Hope that helps :)

They integrate right into a single black hollow. the two black holes integrate to make the "new" black hollow, it quite is a mixture of the two. Their experience horizons fuse. sure, the effect of two black holes colliding is a bigger black hollow. The radius of the hot black hollow is approximately the sum of the radii of the two unique black holes. yet black holes are rather small---even a black hollow that has eaten an entire galaxy is smaller than the photograph voltaic gadget. If the Universe keeps to enhance (as is expected), then there's no way that the entire quantity of the Universe would desire to be taken up by skill of black holes.

Physical Law of a... - ) - Vacuum space..This is a written physical law of a vacuum space. In that a massive created Universe to settle at a Relative -0- Vacuum can create a warp or rip known as a black hole, at a greater vacuum, of a smaller space across the massive Universe.

The Gravitational Pull is so great that it pulls in LIGHT!
NO Man Made Substance would survive getting even Close to a Black Hole.
The Probe, including the Camera would disintigrate long before it gets even close to it..., sorry....!

I believe black holes are pure energy conversion machines. i/e, they pull all matter into them and spew out pure energy in the form of gamma rays.
It is believed by many that every galaxy has a black hole at it's centre which it orbits around. I beilieve that eventually in trillions of years, our galaxy will be pulled in to the black hole at the centre of it.

First you have to find one and nobody knows where one is!
