Philosophy 201 Guidelines
Cogito ergo sum
Here in the Philosophy forum we will talk about all the "why" questions. We'll have conversations about the way in which philosophy and theology and religion interact with each other. Metaphysics, ontology, origins, truth? They're all fair game so jump right in and have some fun! But remember...play nice!

I'm not saying that B-theory is a reality, I'm just saying what it suggest. In B-theory all of spacetime exists, therefore everything in space at every point in time exists. The illusion is that we are moving through spacetime, wherein reality, if B-theory were true, we already exist at every point in time that coincides with our life spans. The illusions is that we move from point a to point b, from t1 to t2,. How the illusion would work is beyond me.
Yes, it's very strange, the past you would be experiencing, would be in, his present, in his "now" just as the present you is in its "now". How else cuold it be if all of time, if each point in time, is coextant with with every other point in time? The whole thing is there which is why they call it the BLOCK UNIVERSE. Like I said, how the illusion is thought to work is beyond me.
Yes, it does. Not only that, but all the other you's, in there own "nows" of course, if they knew about B-theory, could be asking themselves the same question. Perhaps the future you has already figured it out.Last edited by Jim B.; 05-26-2020, 07:24 PM.

Originally posted by JimL View PostExactly, and in B-theory, time is a dimension, it doesn't flow into the future, just like spatial dimensions, it's all there, and everything in time and space is all there. That being the case, in B-theory nothing in the universe actually changes. The question then becomes, if B-theory is true, how is it that we experience change in a universe that itself is changeless?

Originally posted by Chrawnus View PostI don't think absolute simultaneity is a necessary facet of time under A-theory. If the "time" of a certain object or locale is simply it's total rate of change, then you moving close to lightspeed and only experiencing one second while 1000 years passed on the earth would simply mean that the "rate of change" for you would be 31,536,000,000 times (or whatever the correct ratio between 1 second and 1000 years is, the number is just based on a quick google conversion) slower than for the earth. I don't see any problem for A-theory under this assumption.

Originally posted by Jim B. View PostBut my point was to try to imagine a reality that's outside of time altogether, that has no influence on what happens within time. It's conceivable that this reality would have no bearing on whether time was 'open' or 'closed.' The fact that there can be an 'outside' to time doesn't necessarily tell us what the external or internal nature of time is.
Yes, I get that part. There's a phenomenal aspect that the physics leaves out just like with consciousness. I don't see why we would automatically defer to physics in these matters, at least exclusively, without at least seriously considering that both approaches may be 'right' but that we don't understand the nexus, and that physics, like all human endeavors, probably has a blind spot.
But the past "me" would also have to be moving "through" time (as in an A-relation) in order to be experiencing anything at all. For a B-Theorist, it's either all an illusion or it's an infinite series of frozen snapshots.
I'm already the "future me" relative to when I started writing this post, and I still don't know!
I'm not a physicist, I'm just a GED grad. I was hoping BP could make sense of it for me.Last edited by JimL; 05-26-2020, 08:17 PM.

Originally posted by Jim B. View PostI think the assumption is that the future already exists for ppeople on earth that doesn't yet exist for the person traveling at close to light speed. The B-Theorists would say this supports their claim that time is like another dimension of space. I'm not sure it does.

Originally posted by Sparko View PostA-theory assumes some universal time state, "the present," that everyone exists in. In my example, you might have experienced 1000 years, while someone else only experienced 1 second, yet the fact that you can still see them, begs the question that you are in the same "present", otherwise how can you see them?
