"The End of Time" by J. Barbour.
I don't see how this would work though.

ZapperZ said:I would like to remind everyone involved to two very important points:
1. Please review the https://www.physicsforums.com/showthread.php?t=5374". There appears to be a propensity here to make unverified speculation. Please note that unless what you are posting is based on established physics or on peer-reviewed publication, then you are making a personal theory or an unverified speculation. This is not allowed on here outside of the IR forum.
2. If you do not stick with physics issues, but meander into esoteric and unverifiable qualities, then this will be moved out of the physics subforums and into philosophy. So the fate and quality of discussion of this thread depend on you.
Zz.
This can't be answered as it stands because as we say in Dublin "you're startin' from the wrong place".Can space exist without time?
shaunculver said:Hi ZapperZ,
Could you point out what was said that motivated your post?
It's amazing what one can learn in 10 minutes reading.Ok well I read a little more,mostly einstein's stuff.
Don't assign physical reality to mathematical constructs.That makes sense because space is not nothing,it is something with a structure,
This is meta-physics. Discussions about 'existence' belong in the philosophy forum.and if it exists it needs a time in which it exists.

Your original questions are of no practical significance. Time is change, if there is no change there is no time. If there is no matter there is no space, despite any snippets of GR you might have read.
Movement requires matter. Try defining movement without a frame of reference.Hence why einstein/aristotle said space,movement, and time are inseperable. Space is meaningless without time.
Oh and by the way,I would take "snippets of GR" over what you have to say anyways mentz,so there is no point in contradicting it when trying to explain something to me.
The relationship between time and space is inseparable, meaning that they are interconnected and cannot exist without the other. Time is considered the fourth dimension that completes the three dimensions of space (length, width, and height).
Time and space affect the movement of objects through the concept of spacetime. According to Einstein's theory of general relativity, objects with mass cause a curvature in spacetime, which affects the path of objects in motion.
Photons, or particles of light, are the carriers of electromagnetic radiation and have a constant speed of light. They play a crucial role in the concept of time and space as they are used to measure time and distance in the universe.
Yes, photons exist in both time and space. They are massless particles that travel at the speed of light and do not experience time as we know it. However, they do experience time dilation when traveling near massive objects.
The existence of photons has greatly impacted our understanding of time and space. Their constant speed of light has led to the development of the theory of relativity, which explains the relationship between time, space, and gravity. Photons also provide a way to measure and study the vast distances and timescales in the universe.
