Time Travel & Energy: Possible Violation of Conservation Law?

Click For Summary

Discussion Overview

The discussion revolves around the concept of time travel and its implications for the law of conservation of energy. Participants explore the feasibility of time travel, particularly into the future, and whether such phenomena would violate established physical laws.

Discussion Character

  • Exploratory, Conceptual clarification, Debate/contested

Main Points Raised

  • Some participants propose that time travel into the future is possible and does not violate the conservation of energy.
  • Others question the conditions under which time travel is possible, specifically mentioning the need to move faster than light.
  • A participant expresses uncertainty about the mechanics of accelerating in time travel.
  • One participant suggests that while building a time machine may be theoretically possible, it would require an impractical power source.
  • Another participant explains that time travel into the future occurs whenever one body moves at a velocity relative to another, referencing Einstein's theories and empirical measurements with atomic clocks.
  • There is a mention of sarcasm in the discussion, indicating some tension among participants regarding the seriousness of the topic.

Areas of Agreement / Disagreement

Participants generally agree that time travel into the future is theoretically possible, but there are competing views on the implications for energy conservation and the mechanics of time travel.

Contextual Notes

Some claims depend on interpretations of relativistic physics and the conditions under which time travel is considered. The discussion includes unresolved assumptions about the feasibility of time machines and the necessary energy requirements.

Who May Find This Useful

Readers interested in theoretical physics, the implications of relativity, and the philosophical aspects of time travel may find this discussion relevant.

Suppose time travel is possible. Then will it violate the law of conservation of energy??

Time travel is possible - into the future anyway.

And No, it doesn't.
 
why is time travel possible? don't you have to move faster than light to time travel?
 
I'm pretty sure I am not moving FTL right now...
 
Maintaining a constant velocity in terms of time seems to be relatively simple. But, I am having a problem with accelerating in a positive or negative direction.

I was under the impression that it is possible to build a time machine, but it would be useless since you would need a power source greater than a star's.
 
In answer to Chrono and Jimmy, time travel into the future is not just a possibility, but occurs whenever one body moves with a velocity wrt another. It was described by Einstein and is a consequence of the speed of light being constant for all observers. It is only really noticeable at high velocities (ie close to c)
When you fly to New York from London you actually travel about a billionth of a second into the future! This has been measured with Atomic clocks and agrees with Einstein's predictions.

So, travel quickly - see the future!

Yeah guys there is no need to get sarcastic ! Thank you Adrian!
