Might as well ask, is there something other than the usual concept of just claiming that "time" is a measurement?
Time is a speed also, if one only uses the measurement of time?
Light moves at a speed, so can time only move that fast also? (you can make the measurement of time any interval you want to -- perhaps only -- up to the speed of light then?
Why that speed limit? What is holding back light from occuring all at once or even being faster?
(Please no experiments here about light speed at this time -- it detracts from the thought process!)
Peter Lynd was just at Wired.com again in June, and I do think that time does exist, because of sequence of events and because of the speed limit of light! (How anyone publishes anything by him is weird to me!)(I could write nonsense also, I guess!)
So first, time is the movement needed for something to occur, however small a time measurement that becomes! (I guess that depends on how fast --- superstring theory -- just for one theory --- combines or uncombines together -- there is a speed of action there, as with anything.)
So, time needs "space" to allow it to happen, and time needs "movement" to allow it to happen, and time needs "a speed of action" to allow it to happen, as far as measurement to occur, and time needs an "energy" to allow it to happen!
So first, if time was not treated first as a measurement, then perhaps, a different view could take hold on what time really is!
Oh, and perhaps gravity slows down anything, so time also is affected by gravity also!
So, transposing "time" from the bottom of the heap of space, energy, movement, and gravity, perhaps it can also move to the top of the heap, and this is why the Past could not be changed, in one sense of the view, because as soon as the Past is changed, you branch off the current timeline, and cause another timeline to start! (You can imagine the timeline being the same as the original timeline for only briefly, but then the future of that timeline -- for you are no longer further in that original timeline -- can not really be pursued as to what more would happen in the future -- so that future is blocked from your perception.)
The Past was the same up to that point, where the branching action took over, and the time line followed the branching and the rest of the possibilities faded from perception at that point!
Someone said that timelines may converge back together, but that may only occur sometimes, and if it did occur, then there is one broad-based timeline that has to occur. I fail to see where that can happen though, meaning to me it does not happen!
:D
Whoaaaaaa!
So better to say that you can not go back in the Past, and change that point unless one is going off into a different timeline, in which case, the rest of the Past from that point -- did not change!
So perhaps, one could only travel to the Past of something similiar to the Past of one's own happenings, unless one can backtrack all the way to the Big Bang, which is another barrier, that can not actually be surpassed, like the speed of light!
So, time has limits also!
