n How close can we get to a black hole before getting pulled into the black hole?
=//__Popular Opinion__//=

• It can be said that black holes are really just the evolutionary end point of massive stars.
=//__Black Holes: What Are They?__//=

The star eventually collapses to the point of zero volume and infinite density, creating what is known as a " singularity ".

At this radius, the escape speed is equal to the speed of light, and once light passes through, even it cannot escape.

==Since black holes are small (only a few to a few tens of kilometers in size), and light that would allow us to see them cannot escape, a black hole floating alone in space would be hard, if not impossible, to see.==

However, if cloud of interstellar matter passes close the radius of a black hole, or is close to another "normal" star, the black hole can accrete matter into itself.

The X-rays are sent off into space before the matter crosses the Schwarzschild radius and crashes into the singularity. Thus we can see this X-ray emission.

The wormhole itself is two copies of the black hole geometry (Black Hole <
> White Hole)connected by a throat - the throat, or passageway, is called an Einstein-Rosen bridge.==
