More on Black Holes

Black holes don't emit electromagnetic radiation, such as a star would do, since light cannot escape due to the large gravitational attraction (According to Einstein 's Theory of General Relativity, light is bent by gravitational pull; this has been verified in the observation of bending of starlight grazing the Sun's surface during an eclipse).

Starlight is bent by a very massive galaxy cluster Abell 2218. The galaxies lying on the arc are galaxies 5 to 10 times further than the lensing cluster of galaxies.

There is an exception to this scenario, as postulated by British astrophysicist Steve Hawking. According to Hawking, a black hole might emit radiation and/or particles. These particles could travel above the speed of light for a short period, as established by the Uncertainty Principle. According to the Uncertainty Principle, one can measure the energy (and velocity) of a particle (including a photon, which is the carrier of the electromagentic interaction) only with a certain amount of precision in a given time interval; the shorter the interval, the more uncertain is the energy. This is a fundamental limit of Nature, and has nothing to do with the quality of the instruments devised to make the measurement.

A black hole can lose mass, and eventually it can evaporate. According to Hawking, matter which might have fallen into the black hole (including a spaceship) will reappear into a baby-universe. This baby-universe could have a black hole, and this black hole would be the way to reach back into the real universe. This black hole associated with the baby-universe would then evaporate, spewing the material, such as the spaceship, which originally fell in the "real" black hole.
