I was thinking that time is just the perception of movement into space-

So could we get read of the time-dimension and replace time in our
equations with movement in space? Is any theory moving that way? I d
be grateful for any informatin.
Thank you.

Compare the fuel in the tank of the winner and looser of
a drag race. Time is just that real and it is never free.

Sue...

But they say that men age better than women.
Even if you have the same tank of gas, some will get more miles to the
gallon than others.

Time is a real strange thing, because when I am at work, it drags on
and then when I get home and read Usenet it flies by like it had
wings.

And its not fair because time seems to go on forever, when you are not
having fun, but flies by when you are.
So if you want time to last, then you have to preoccupy yourself with
things you don't enjoy doing.

I am on holidays now, but just before my holidays, time literally was
standing still. And it wasn't even just my perception of it.
I was not working at any different speed than I usually do, but it
seemed like in 15 minutes I was doing half a days work.

I would do my work, and then check the time.
15 minutes.

I get home, post a message to Usenet, there's two hours gone. 3 if I
try to look something up.

If I dare reboot my computer?
Forget it, theres an hour and a half gone.

You know inside, I don't feel like I am aging at all. I don't feel any
different than I ever did.

I think it is largely psychological.

What we need is some better understanding on the whole aging process,
so we can live longer if we want to.

But regarding this...
http://www.physics.ucla.edu/~cwp/articles/noether.asg/noether.html
Can you actually map time onto a real physical space, no.
Because the expansion of the universe, is not in one moment here and
now.
You can assume, that space expands, and that space is curved because
it expands, but you will only see that, over time.

But what you can do, is project into imaginary space, a 4th dimension.
and map onto that.
But, is that dimension imaginary?
Or is it a real dimension?
Hilbert Space is a real dimension, but we aren't able to span one
moment to the next, so as to detect it or notice it or perceive it.
But that is where the universe is expanding into.
And not just at the edges of the universe, but between every two
points.

But then does that mean that that Hilbert Space is a time dimension?
Well its a physical dimension, and if it expanded not linearly, but
was sporadic, and not even consistent, but paused for a million years
and then expanded another Plank length in another Plank moment, we
would never know.

All we know is that when the universe does expand into that space, it
gives rise to gravity and the other forces.

Why everything is always moving. The expansion of space-time forces
thing to move.
Newton and Galileo said that if you start something moving, in the
absence of force it will keep moving in a straight line.
Why should it keep moving at all though was one of Newtons questions.

Einstein said that it will keep moving, in a geodesic.
And well that is because, if you take a balloon and lay it on the
ground, it is a straight line, but expand it, and it becomes a curve.
However, what really curves, is the past trajectory. The object still
for all intents and purposes, did travel in a straight line through 3
dimensions, it just ends up looking like it curved.

But the fact that it does curve, well is that proof that time is a
real thing, or proof of Hilbert Space?

What if, time was not an issue, and every Plank Moment the universe
mechanically clicked another clog on a big wheel and expanded one
Plank Length, and it was fluent mechanical motion, perfect elasticity,
perfect fluidity, so that the grains of quarks or the bubbles of
quantum foam touched, and expanded along the t axis.

Like it seems to.

Then maybe there might be some way, to use Atoms to tell universal
time.

And maybe we just haven't figured out a way to do it yet.

We can see the curved trajectory of a ball, but we can't see expansion
along the t axis itself. Because our eyes and our measuring equipment
are also expanding in Hilbert Space.
