Re: What is "spacetime" really?

Boof-head:

If you want to really consider the 'reality' of time, then ultimately you have to accept that time is "something that evolves" in QM interactions, or something that "started" when the universe did, in relativistic terms.
Rather than repeating myself over and over, please read or re-read my following most recent comments on time from the previous page... and then, if you will, tell me how specifically you disagree:

Post 664 to essay

Post 670 to Doctordick (my "time piece" re-bumped several times in this thread.)

I totally disagree with your opening statement above.
Time is how long it takes things to happen, but since everything is always happening (moving) everywhere, the "time-keeper" determines what event in particular he is timing, then clicks his stopwatch, so to speak at his selected "beginning" and "end" of the event upon which he is focused.

Of course,what units of time he uses is arbitrary... usually based on fractions or multiples of our common earth-commensurate cycles, the day or year.

Beyond such "time keeping" there is no "time" between "the future" (not yet happened) and "the past" (not still happening.) No "time in between".... always, perpetually, ongoing NOW.

Your reference to time starting "when the universe did" is strictly linear thinking and in denial of the possibility of a cyclic universe. Further, where do you think all the matter/energy/plasma in the cosmos came from to "start the universe?" Did it magically appear out of nothingness? Might as well go with religious mythology and believe that "God" pulled the cosmos out of a cosmic Magic Hat!

Hypography?

Hypography [n.]: A combination of "hyperlink" and "bibliography" - ie, a list of links to electronic documents. Comparable to discography and bibliography, but not cartography.

We have been online since May 2000, and aim to be the best place to find and share science-related content of all kinds.

Share the love!
