How can observers moving at different speeds all measure light at the same speed? ... The amount of time dilation depends upon the speed of the trip "the closer the astronaut gets to the speed of light, the more the Earth years get compressed in his frame of reference. ... (John Gribbin, 1990, p. 2) Subatomic particles often travel near the speed of light and thereby experience very large time warps'. ... However, faster-than-light travel cannot be achieved by straightforward acceleration, for a body's mass rises without limit as its speed approaches the speed of light. ...

Now, according to Einstein you can't travel at 100% the speed of light because He predicted that objects gain mass as they accelerate to greater and greater speeds. ... Also, in fact, as far as we know nothing can match, or exceed the speed of light. ... They discovered that light always traveled at the same speed: 186,000 miles per second. ... The speed of light remains constant for all observers. ... The ship approaches the speed of light. ...

When traveling anywhere in our universe, time slows as an object reaches the speed of light, according to Einstein's theory of special relativity. This makes scientists believe that if we could somehow travel faster than the speed of light, that we can travel backward and forward in time. ... If you think about it, while traveling in a car, train, or plane, you reach speeds that get closer to the speed of light, which means that we have already actually traveled into the future, but in an incredibly small way. If you and a friend were to set your watches at exactly the same time, then ...

E= in the equation stands for energy , M= stands for mass, and C= stands for the speed of light. ... C equals the speed of light (186,000 miles per second). ... It rolls along at great speed. ... As it approaches the speed of light, its mass will be enormous. ... You simply cannot shoot them near the speed of light! ...

Peter gets into a rocket and travels to a star ten light years away. A light-year is the distance light travels in one year which is approximately 9.4607 × 10 12 km (Crockett, 2013). He moves at 80% the speed of light. When he gets to the star, he turns around and comes back at the same speed. ... Theoretically, if you can get your rocket going near the speed of light and you went as far as one of the galaxies and came back, millions of years would have elapsed on earth, yet the trip might only take you a few weeks. ...

Albert Einstein was born in March 14, 1878 in Ulm, Germany. His parents Herman and Pauline (Koch) Einstein were very worried about young Einstein because he was very slow to learn how to speak. When he was young he had no mark of being a genius. He was Jewish but went to a Catholic school were he wa...

An example of his theory of relativity was, if there were twins and if one twin flew into space in a rocket going near the speed of light, and returned after 40 years, he would appear to have aged only slightly, whereas his identical twin who had remained on earth would be old and wrinkled. ... "E- stands for Energy, "M- stands for Mass, and "C- stands for speed of light. ...
