74 Relativity before Einstein Time v = v + V Space Can in principle send objects as fast as we want. Regions arbitrarily far way can effect what is happening here and now. Einstein s Big Idea: Limit the range over which things can have an affect 74

75 Einstein s Relativity To limit the range over which things can have an affect: -1) Must be a maximum speed. -2) Max speed must be same regardless of how fast you are moving. (otherwise we are back where we started v + V) 75
