Discussion Overview

The discussion revolves around the concept of whether the future exists according to General Relativity (GR) and how this relates to determinism and time perception. Participants explore various interpretations of time, determinism, and the implications of relativity on the nature of the future.

Discussion Character

  • Debate/contested, Conceptual clarification, Exploratory

Main Points Raised

  • Some participants question the meaning of "future exists," suggesting that it may relate to whether the future is predetermined.
  • One participant notes that while relativity is a classical theory and deterministic, the implications of this determinism are debatable.
  • Another participant references the light cone diagram from Special Relativity as a way to visualize the concept of the future.
  • There is mention of the Schrödinger wave equation as another viewpoint on the nature of time and determinism.
  • One participant speculates that the original poster (OP) may be inquiring about the possibility of time travel to the future as depicted in science fiction.

Areas of Agreement / Disagreement

Participants express differing interpretations of the concept of the future and its existence, with no consensus reached on whether the future is predetermined or how General Relativity relates to time travel.

Contextual Notes

Participants highlight the complexity of determinism in relation to quantum mechanics, indicating that assumptions about determinism may conflict with quantum theories.

I'm afraid I don't understand what you mean by 'future exists'.
If you mean to ask whether future is predetermined, any deterministic theory will answer is in the affirmative.
Also, each observer experiences only his present in his frame of reference :-p ! Two observers mayn't agree on the temporal order of events,though.
 
no not really...but it does depend on what you mean. generally speaking relativity is a classical theory and is therefore deterministic, but what that means is also debatable.

you can see a diagram via SPECIAL RELATIVTY that shows the "future" via a light cone...

Or maybe you are thinking of determinism:

http://en.wikipedia.org/wiki/Determinism

which could mean that IF we knew every initial condition now then the future might be predetermined...but that conflicts directly with a lot quantum mechanics...
 
I'm not 100% on this, but I think the OP is more talking about whether general relativity allows time travel to the future ala science fiction (think Doc Brown going to see Marty's children).
