Question: Is time travel to the past possible according to quantum mechanics?

Click For Summary

Discussion Overview

The discussion revolves around the possibility of time travel to the past according to quantum mechanics and other theoretical frameworks, including relativity. Participants explore concepts related to time, entropy, and the implications of various physical theories on time travel.

Discussion Character

  • Exploratory
  • Debate/contested
  • Conceptual clarification

Main Points Raised

  • One participant suggests that time is the movement of existence and proposes that one could theoretically travel into the future by manipulating the speed of existence, but expresses skepticism about the possibility of traveling to the past.
  • Another participant states that time is defined as an increase in entropy and asserts that while forward time travel is theoretically possible under certain conditions (e.g., intense gravitational forces), time travel to the past presents paradoxes.
  • A participant acknowledges the discussion of time travel in the context of relativity and questions whether quantum mechanics might offer alternative possibilities for past time travel.
  • There is a suggestion that some aspects of relativity may influence quantum mechanics, although this is presented as a personal hypothesis rather than an established fact.

Areas of Agreement / Disagreement

Participants generally agree that time travel to the past appears to be impossible or paradoxical, but there is no consensus on whether quantum mechanics might provide a different perspective or solution. Multiple competing views remain regarding the nature of time and the feasibility of time travel.

Contextual Notes

Participants express uncertainty about the definitions of time and the relationship between quantum mechanics and relativity, indicating that assumptions and interpretations may vary significantly.

I've been thinking about time travel...who hasn't. Since time is simply the movement of exsistence, it seems that one could go into the future faster than normal by slowing the speed of exsistence around them. I thnk this is pretty well supported. However going into the past does not seem possible. At first thought you think to speed up the movemt of exsistence in your confined area. Not only would you age too quickly, but there is only a point in which you would reach almost complete stillness. If you could go past that point, then things seem like they should start moving in revearse. I don't see this happening though.

Question: How to separate ones self from noraml exsistence so that you could speed up or slow down yur own movements. Spacial distortion comes to mind, but please be more specific than that.

Question 2: Is traveling back in time possible in anyway through accepted scientific methos?

First off, time is defined as an increase in entropy.

Secondly, time travel is theoretically possible. See Einstein's relativity. You could go forward in time when intense g forces are at hand. But, I'm sure you already know that; I have a feeling you're trying to ask something more complex, so are you?

lastly, time travel to the past is paradoxical.

Yes, trying to lok at timetravel as a possibility. I know what you are talking about in realitivity, its very similar to what I discussed. As I said above time travel to the past seems impossible, but is it possible in some other theory, perhaps in QM?

Beautifully put, Majin.

In QM? I believe some parts of relativity do govern QM in some occasions...but that's just my guess.
