Discussion Overview

The discussion revolves around the hypothetical scenario of time travel to moments after the Big Bang, specifically addressing the implications of being at a fixed point in space during this time. Participants explore concepts related to the nature of the universe, dimensions, and the consequences of such time travel.

Discussion Character

  • Exploratory, Conceptual clarification, Debate/contested

Main Points Raised

  • One participant questions whether the universe is a submanifold of a hyperspace, suggesting that the question of being outside the universe is contingent on the existence of such a hyperspace.
  • Another participant argues that if one is at rest relative to the universe, they would not end up outside of it, asserting that one would need to exceed the speed of light to reach beyond the universe's edges.
  • A different viewpoint suggests that the question is poorly defined, proposing that one would be subjected to extreme conditions, such as being burnt and crushed, if they were to travel back to that time.
  • Another participant posits that outside the universe, dimensions as understood within the universe may not exist, and questions the existence of coordinates before the Big Bang.

Areas of Agreement / Disagreement

Participants express differing views on the nature of the universe and the implications of time travel, indicating that multiple competing perspectives remain without consensus.

Contextual Notes

The discussion includes assumptions about the nature of time, space, and dimensions that are not fully explored or defined, leading to unresolved questions about the implications of time travel in this context.

If time travel were possible in the current day and age - And you were to stay in a fixed point ( So you traveled in time but without changing your location) - If you were to go back to momments after the big bang , Where would you be?

Since the universe wasnt created yet - or hadnt expanded as the point in which you were fixated, would you be outside the universe? In another dimension?

Any ideas?

Your question is if the universe is a submanifold of a hyperspace. This is impossible to prove from withing the manifold. If there is a hyperspace then your question makes sense and is already answered, if there is no hyperspace then your question is pointless.
 
If you are at rest relative to the universe you will go wherever it goes, you would not end up outside of it. Time traveling or not, you would not need to stay at a fixed point but rather accelerate to a velocity faster than the speed of light to go beyond the edges of the universe.

Asking about what's beyond the edge of the universe is like asking what is at the edge of the Earth or the end of the rainbow. These things don't exist.
 
The question obviously isn't well defined but hypothetically you would just be burnt and crushed into your atomic then nuclear constituents, like everything else.
 
Outside the universe, there arent, at least in our vision, dimensions like as inside the universe. Before big bang, the coordinates you would stand at the moment, wouldn't exist. OR, they would exist somewhere in whatever caused the big bang.
