Does time travel violate conservation of mass?

That means that according to conservation of mass, a quantity equal to your mass has been subtracted from something else. But mass doesn’t spontaneously disappear in order for time travel to occur, so that’s impossible.

Would time travel violate conservation of energy?

It is true that general time-travelling violates conservation of energy. If you transport yourself into yesterday, you appear twice in the universe for that day, which means twice your rest energy, which is a lot of energy. It may mean that time-travelling is inconsistent and therefore impossible.

Does time travel violate the second law of thermodynamics?

The second law of thermodynamics shows that the arrow of time point in the direction of increase in disorder. If somehow we travel in past then also we cannot violate the second law of thermodynamic because nature has solution for its own problem.

Is there a law of conservation of mass?

The Law of Conservation of Mass dates from Antoine Lavoisier’s 1789 discovery that mass is neither created nor destroyed in chemical reactions. If we account for all reactants and products in a chemical reaction, the total mass will be the same at any point in time in any closed system.

Do wormholes violate Thermodynamics?

No, black holes do not violate the 2nd Law of Thermodynamics.

Does time travel violate the law of Conservation of mass?

Thus you may still have a form of conservation of mass across timelines. Not nessecarily. It could be that the rule of conservation of energy is simplistic, and a more nuanced version is needed to acount for time travel. It could be that time travel has energy requirements that balance it out.

What is the law of physics that conserves energy and momentum?

If laws of physics do not change with time, energy is conserved. If laws of physics do not change by translation in space, momentum is conserved. If laws of physics do not change with rotation of your system, angular momentum is conserved. They part of the so-called Noether’s theorem.

Is Energy conserved during time travel?

Globally, energy is not conserved and in cases of time travel, the structure of spacetime that would allow for that also would have energy not be conserved globally. Locally is another matter$\\endgroup$– JimDec 9 ’14 at 19:05 $\\begingroup$You should probably specify that you are talking about time travel into the past.

Is time travel possible in real life?

Basically, if time travel is possible then different times are part of the same system and conservation of energy is conserved. Conversely, if they are not parts of the same system, time travel will be impossible.
