Time Travel & Energy: Possible Violation of Conservation Law?

In summary, the conversation discusses the possibility of time travel and whether it violates the law of conservation of energy. It is agreed that time travel is possible, although it only applies to traveling into the future and not the past. It is explained that time travel occurs whenever one body moves with a velocity relative to another, and this was described by Einstein. It is also mentioned that time travel into the future can be observed when traveling at high velocities, such as when flying from London to New York. However, it is noted that a powerful energy source is needed to build a time machine.

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.
 
  • #3
why is time travel possible? don't you have to move faster than light to time travel?
 
  • #4
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!
 

1. Can time travel violate the law of conservation of energy?

According to the law of conservation of energy, energy cannot be created or destroyed, only transferred or transformed. Some theories of time travel involve the creation of new energy or the transformation of existing energy, which could potentially violate this law. However, there is currently no scientific evidence to support the possibility of time travel, so it is not known whether it could actually violate the law of conservation of energy.

2. How would time travel affect the energy of the universe?

If time travel were possible and could violate the law of conservation of energy, it could potentially have a significant impact on the energy of the universe. The creation or transformation of energy through time travel could alter the balance of energy in the universe, potentially leading to unexpected consequences and disruptions to the laws of physics.

3. Is there any evidence of time travel violating the law of conservation of energy?

No, there is currently no scientific evidence to support the possibility of time travel, let alone any evidence of it violating the law of conservation of energy. While there are many theories and speculations about time travel, they are purely hypothetical and not supported by any empirical evidence.

4. What are some proposed solutions to the potential violation of the law of conservation of energy in time travel?

Some scientists have proposed that the law of conservation of energy may still hold true in the context of time travel, but it could be applied differently. For example, the energy used in time travel could come from another dimension or parallel universe, thus not violating the law of conservation of energy in our own universe.

5. How does the concept of time dilation relate to the law of conservation of energy in time travel?

Time dilation, a phenomenon predicted by Einstein's theory of relativity, suggests that time can pass at different rates for different observers depending on their relative speeds. This has been used in some theories of time travel to explain how energy could be conserved, as the energy used in time travel could be offset by the differences in time experienced by the traveler and the rest of the universe.
