Question:
Explain the space/time concept.
Replies:
This is not easy in a few words. The old way of looking *(before Einstein)
was that every point in space would have the same time. That anything
happening at some other place would be simultaneous with what is happening
here. When Einstein realized that the velocity of light was the same for
all observers, then it meant that all points in space do not have the same
time. It also means that you would disagree with someone else who is far
away about the sequence of events and you could not agree is two event were
simultaneous. What this meant was that time and the three directions in
space were very much like four different dimensions of space, that time was
really very much like one of the x, y, or z directions. Relativity effects
arise mostly out of the mixing together of these different directions in
a four dimensional space. I think I took too many words and may not have
helped you. Ask again if that is the case.
