... forming a four-dimensional space called spacetime (Hawking 118). This space is not flat but rather distorted and curved by the matter and energy within it. The curvature of spacetime can be observed in the bending of the light or even radio waves that travel close to a strong gravitational field. This field would be so strong around and within a black hole that not even ... volume (internet 1). The second discovery that sparked researchers to believe these objects were infact black holes was the detection of a spectral line from one galactic nucleus that indicates the presence of atoms ...

... be moving only though time. If they moved a little bit, they would be moving though space a little bit, but still mostly though time. If one were to travel at the speed of light, what changes would they experience in time? The answer is simple; they would be traveling through space, with no travel though time (Hewitt 214). They would be as ageless as ... slightly for everyday speeds, but significantly for speeds approaching the speed of light. If we were to attempt to travel to the nearest star, Alpha Centauri, which is 4 light years away, even traveling at the speed of light would take...
