My post on the fundamental relationship of space and time was removed. I have been told it was removed because it had also been posted in another forum. My concern is that this question has philosophical and physical aspects. I think it requires a cross-discipline approach. Is there an...
Sorry, I only wanted to try my idea out on the philosophers, who probably don't read much in this forum. And it wasn't the same exact post, I made some small changes to address the academics in the other forum.
Zz, do you really expect that everyone who visits physicsforums.com reads every...
Thanks, Zz
Well, I did say imagine, didn't I?
But I think you are right in physical terms. My little mental exercise does require an observer who can move from place to place, and must require time to do so. So I have merely moved the property of time into the obervation apparatus, not...
To elaborate, it is possible to imagine a world which has spatial relationships but has no moving parts. There would be no motion, no change, no evolution of time in such a world.
On the other hand, if I try to imagine a time world, in which there are no spatial relationships, no objects, no...
I can imagine an unmoving space, devoid of time,
but what motion could take place in time devoid of circumstance?
So is space more fundamental than time?

Your statement is probably an over generalization. All physics is based on measurement. Time can be measured. We do not have to speculate about what time it is, we can look at a clock. We do not have to speculate about how much time it takes a jet at mach1 to travel one mile, it can...
If the babies have babies and so on to whatever counts as infinity, then isn't the system of however many local universes still open? The idea of a closed universe seems to me to be lost among so many potential babies. Then a black hole is where a universe opens to the inside.

I see you have had a long discussion on 'time' over in the SR forum, and I took a look at that before going on here. In fact, I was thinking of coming back here, but not for speculations. You may know that idle speculation is frowned on here.
The SR forum discussion ended when Doc...

Sorry couldn't resist.
Actually, I can't reply right now, but I want to. Don't feel well today.
Yes, infinite times.
Of course, light speed can vary under conditions in our universe, even in the laboratory. But I usually think of the SOL as a unit...makes it easier to think...
Thanks for the reply cP.
Chronos objects to the idea of an imaginary universe because "Imaginary universes have no observable consequences in our universe." I am not sure this has been completely determined. An analogy may be in the classical objection to black hole singularities...we...
What is the geometry of time?
My impression from the end of the concluding seminar at the singularities miniprogram at KITP UCSB in January 2007 conducted by Gary Horowitz was that the key issue is the Problem of Time. He seemed to think that a new view of time is essential to any real...
sA has always been a good friend to me as long as I've known him, on this forum as well as on another before I came here. If I were in MN I'd drive down to Greenville to find out what is going on. I am also still hopeing his absence is temporary and that he will return to us.
Best wishes to...
How dissappointing. In my view the side discussions were the best part of the program. Not to say being at the seminar was anything less than a huge treat for me. Oh well. Thanks for the update.
