If all the space there has ever been exists right now, does it follow that all the time there has ever been exists here in this space?

This is not a trick question. Einstein theorised and NASA has shown that time is curved because of the effect of gravity upon it. This is known as the geodetic effect. If the effect of gravity upon time can be measured, then surely it must have geometric dimensions, or we couldn’t have discovered that it is curved. This has led to various theories about the possibility of time travel itself being put forward, by visionaries such as Albert Einstein and Stephen Hawking.

Have you seen the time?

If it has geometric dimensions then dates must be the equivalent of map references along it. So, if time exists as a thing and we exist on it at a given point, where is the rest of it? For example, if I move from the hall to the kitchen, the hall will still be there and the space that is the kitchen would have been there all along. So, in theory, somewhere out there must be yesterday.
