I was thinking while on a bus ride. The closer objects approach the speed of light, the more time dilation occurs. Now I assume it is basing speed on a single point in in space (x,y,z), let's say from the exact center point of the universe. our galaxy is therefore traveling at a speed of 1.34 million miles per hour (600 km), so does that not mean the our concept of time is already dilated? Our concept of time is not as it would be if we were at a true state of rest (as with the universe itself), or that if we were situated on a planet in a faster or slower moving galaxy, is that not true? So therefore there should be a universal time and individualized galactic times...there is also some variations adding speed on the galactic arm as the galaxy spins, that in itself should add/subtract depending on the rotation speed. I used the following references for information:<br />http://hypertextbook.com/facts/1999/PatriciaKong.shtml<br />http://en.wikipedia.org/wiki/Time_dilation<br />Anyone care to comment of my theories, and/or disprove or add to it?
