    Future Gr
In summary, the conversation discusses the concept of the future and whether it is predetermined. It is mentioned that deterministic theories support the idea of a predetermined future, but there is also discussion about different perspectives and interpretations of this concept. The possibility of time travel to the future is also brought up, with a reference to the Schrodinger wave equation. Overall, the topic is complex and debatable, with various theories and viewpoints to consider.

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 :tongue2: ! 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:

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).
 

1. What is GR and how does it relate to the concept of the future already existing?

GR stands for General Relativity, which is a theory developed by Albert Einstein to describe the force of gravity. According to GR, the future already exists because time is seen as a dimension that is interconnected with space, meaning that all events in time exist simultaneously.

2. How does GR explain the concept of the future already existing?

GR explains the concept of the future already existing through the concept of spacetime. This theory posits that time is not a separate entity from space, but rather part of a four-dimensional fabric. This means that all events in time exist simultaneously and the future is already determined by the current state of the universe.

3. Does GR contradict the concept of free will?

This is a highly debated topic. Some argue that if the future already exists, then free will cannot exist because our choices and actions are predetermined. However, others argue that GR does not necessarily negate free will, as our choices and actions are still influenced by our consciousness and experiences.

4. Is the concept of the future already existing widely accepted in the scientific community?

The concept of the future already existing is still a subject of debate and is not universally accepted in the scientific community. While GR is a well-established theory, the idea that the future is predetermined is still a topic of discussion and research.

5. How does the concept of the future already existing impact our understanding of time?

The concept of the future already existing challenges our traditional understanding of time as a linear progression. It suggests that time is not fixed and that the past, present, and future all exist simultaneously. It also raises questions about the nature of time and whether it is subjective or objective.
