... human lifetime could pass within the blink of an eye of an alien observer in a distant part of the galaxy, traveling near the speed of light. (Parker) With the idea in mind that time is relative, there is hope that time travel can be accomplished. Traveling near the speed of light slows time down significantly, but then what happens at the speed of light? When the speed of light (referred to as c) is reached, what ... with time can leave a reader baffled and confused. That's all right though, because also according to relativity, matter cannot travel at the speed of light, and much less...

... hole. The first to really take an in depth look at black holes and the collapsing of stars, were a professor, Robert Oppenheimer and his student Hartland Snyder, in the early nineteen hundreds. They concluded on the basis of Einstein's theory of relativity that if the speed of light was the utmost speed over any massive object, then nothing could escape a black hole once in its clutches. The ... name "black hole" was named such, because of the fact that light could not escape from the gravitational pull from the core, thus making the ... called the "escape velocity." Roughly, Earth's e...

... there was a referred. In particular, he believed that the Earth was at rest. Whereas, Newton using Galileo's experiments founded three laws of physics that showed there was no fixed state of rest. Taking this into account, experiments involving the speed of light led to Albert Einstein developing general the theory of relativity. From Einstein we learned space and time are dynamic quantities and the notion ... current situation in the present." (p. 166) The concept of warping through space-time is in itself very fascinating. Hawking describes a wormhole as being a "shortcut" between two d...

... lab is relevant to the person that is in the lab. The principle of relativity theorizes that experiments in an internal frame, is independent from uniform velocity of the frame. An example of this is the speed of light. The speed of light within the internal frame is the same for all, regardless of the speed of the observer. Two events that are simultaneos in one frame, may not be ... the simplist equations, he found a set of 10. To test the general theory Einstein performed three tests. Gravitational red shift, light deflection, and perihelion shift of mercury. To test light deflection, ...

... star becomes a pulsar. This is when the protons and electrons are smashed together so hard that they make neutrons. The Neutron Star then emits beams of light out of both its poles. This is known as a pulsar: these stars do this for about a million years and then they become Neutron Stars that no ... becomes so dense that nothing can escape it; not even light. What forms in this scenario is what is known as a black hole (Moore 57). To escape the gravitational pull of a black hole would take something moving faster than the speed of light. Since even light is sucked into the black hole;...
