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

Click For Summary
SUMMARY

The discussion centers on the feasibility of time travel, particularly the distinction between traveling to the future and the past. Participants reference Einstein's theory of relativity, asserting that while forward time travel is theoretically possible under intense gravitational forces, backward time travel presents paradoxes that render it unlikely. The conversation also touches on the relationship between time, entropy, and quantum mechanics, suggesting that while some aspects of quantum mechanics may intersect with relativity, they do not provide a clear pathway for past time travel.

PREREQUISITES
  • Understanding of Einstein's theory of relativity
  • Basic knowledge of entropy in physics
  • Familiarity with quantum mechanics principles
  • Concept of gravitational forces and their effects on time
NEXT STEPS
  • Research the implications of Einstein's relativity on time travel
  • Explore the concept of entropy and its relation to time
  • Investigate quantum mechanics theories related to time
  • Examine the paradoxes associated with backward time travel
USEFUL FOR

Physicists, students of theoretical physics, and anyone interested in the scientific exploration of time travel concepts.

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.
