Does 'NOW' exist everywhere now ?
« on: 08/02/2025 18:37:05 »
Hello,


I'm Sheepy🐏


This is a nice forum, well done ewe lot.


So, I know that time is all relative and all that and the Universe is big and stuff....and there could be multiple Universes and beyond what we can see there is probably a lot more Universe out there.


Does NOW exist all over the place ?  Even if there are time issues...surely 'NOW; exists in whatever time line is being active. Because, if that was the case, there must be a value for NOW that exists the same time as our NOW...


whajafink ?

Does NOW exist all over the place at the same time  ?




Hugs and shmishes




mwah wmah mwah

Does NOW exist all over the place ?
A philosophical question, not so much a science one, and yet the first reply is by alancalverd, an outspoken critic of philosophy in general.

There being zero empirical evidence for an objective present, 'now' can only refer to a relative thing such as [simultaneous with the posting/utterance/bleat of the word]. As such, it is a reference to an event, and an event is local, so the answer is pretty much 'no'. Relativity of simultaneity says that for distant space-like separated events (anything not 'here'), there is no empirical way to determine the objective ordering of said events. The ordering thus becomes a matter of choice of coordinate systems, an abstraction at best.

surely 'NOW; exists in whatever time line is being active.
Again, depends on if you're using an objective or relative definition of 'now'. There is no evidence of the latter, and the former is a convention, not anything physical.


Got a link for the old topic?  Love to see how the users back then replied.

Which is exactly what I said in fewer words. Thus the accusation that I reverted to philosophy is refuted and science reigns supreme, as it should.
