Time flies like an arrow...Fruit flies like a banana
..JFK has just been assassinated and Einstein is yet to be born.
It's all about the here and now, what we consider the present is only the present from our perspective.
Events don't "happen" then cease to exist, "moments" are not illuminated by time in a similar way that frames on a movie film are illuminated by the projector. We see one frame after another frame, but the earlier frames ( and the future frames) exist at the same "time", we just don't see them. Moments , however,are not illuminated then plunged into darkness since that would involve the passing of time and well.. a moment is a moment, it cannot change over time.
All " moments" are lit, and will always be lit, the past is as alive as the present, ( and the future ?)
Relativity..Special and general.. has been proven correct "time" and "time" again. In a nutshell special relativity states that 2 observers moving with respect to each other cannot agree on the timing of separate events. for example if a row of lights one each side of a road are alternatively blue and red and each pair lights up and goes out in sequence, a stationary observer would see blue lights coming on on both sides then red then blue etc, but a moving observer may see blue and red lights coming on in sequence. Each observer is justified in their view of events. To one observer a red light has not yet come on to another it is on and to another it was on and has gone off..all are correct.
This means that someones present is also someone elses past and someone elses future. Past present AND future all exist AT THE SAME "TIME". I have just started writing this post, I have just thought of writing this post and someone else has just replied telling me it's all bolloc*s.
