Breezy+Time+Dilation

Time dilation is saying that clocks pass more slowly in regions closer to a large object of mass. This was a theory Einstein had and was tested through general relativity tests. This occurrence happens because time dilation is manifested in accelerated frames of reference. This doesn’t happen to just clocks, it also happens to merry-go-rounds, space shuttles, dragsters, and Ferris wheels. To calculate time dilation, there are many equations based on what sort of object is in time dilation, for example out-side a non-rotating sphere, and circular orbits. What happens in time dilation is really hard for most people to understand. Let’s say someone travels into space that travels extremely close to the speed of light. In “Earth” terms, the astronaut has been gone for 7 years, but to him it has only been one year. But to make things even more complicated, it still takes the same amount of time for him each of us on Earth to do small daily things like shower, shave, and brush their teeth. Why does this happen? This happens because time expands and space contracts in the view of the astronaut. This is known as the Lorentz contraction, but just because it exists does not mean that anyone has ever felt its effect. It’s too subtle and small for even astronauts to feel it. http://www.thebigview.com/spacetime/timedilation.html http://en.wikipedia.org/wiki/Gravitational_time_dilation
