So I am wondering:

How do we measure time?

Do we compare time with something else?

Is time a constant or does it vary?

How do we know whether time goes forward (and not backwards)?

Does time exist at all?

Strong gravity (like inside the event horizon of a black hole) is supposed to make time stop up, making gravity the ultimate winner of forces.

Is gravity a "field"? Is it either particles or only pure energy?

The three dimensions which we relate to the cube (length, width and height) disappear when inside a black hole.

The black hole in its finite state is supposed to be represented at its core or inside the event horizon by the "singularity".

All very good questions.


Space and time are closely related it may seem.

That does appear to be so.


Please explain this to me.

Measurement, and all observations, are all and can only be: "relative".


Another question is whether there can be any "absolutes". And whether we can build a view of our existence and that of the universe upon any one absolute or others.


Time passes?

So far, time is that which we can merely measure.

The distance traveled betwen two points in space-time.

Do we compare time with something else?

Yes, the spin of the Earth and it's orbit around the Sun.

Is time a constant or does it vary?

In our Universe it is constant

How do we know whether time goes forward (and not backwards)?

I suspect because the Universe is expanding, although if it started to
contract time will still progress forwards.

Does time exist at all?

No.

Strong gravity (like inside the event horizon of a black hole) is supposed to make time stop up, making gravity the ultimate winner of forces.

Since the black hole is still moving at constant speed through space-time -
time inside a black hole is not affected what ever else happens inside this
hole.

Is gravity a "field"? Is it either particles or only pure energy?

The jury's still out on this one...

The three dimensions which we relate to the cube (length, width and height) disappear when inside a black hole.

Singularity say's yes.

The black hole in its finite state is supposed to be represented at its core or inside the event horizon by the "singularity".
The energy inside the black hole forces all to collapse to a single point
(zero +) but not zero. All dimensions collapse to a dot without a dimension.

Space and time are closely related it may seem.

Space and time can't be separated in our Universe for time as we perceive it
comes about through the effect of bodies moving through space. Time can't be
perceived until a body has moved a distance through space itself.....hence the term
Space-Time.

The above is my take on it all, others will rightly have different understandings of them.

Does this mean if the universe, (and us within it), stopped moving, time would come to a stand-still?

My feelings on this is yes. Plus when the universe ceases to move all matter
will revert to energy because the atom will stop vibrating too.
