Sorry, but I only have very limited knowledge in physics. I came to ponder the concept of time travel.
Backwards time travel has been a topic of discussion for as long as man has pondered his own existence. However, what this simplistic discussion attempts to do is to explain how backwards time travel is an impossibility due to the violation of the law of conservation of mass. For this theory to work, we must assume that the law of the conservation of mass is a given. We must create a closed system with a fixed amount of mass, mass that does not change over time.
As an example, let us assume that our closed system, Earth, has a fixed amount of mass bounded by the vacuum of space. We will call this mass X, which includes the mass of all human beings on the planet. The total mass of Earth X remains unchanged with time. Mass is not created nor destroyed.
Let us assume that someone discovered a way for backwards time travel to exist by creating a time machine. A human with a given mass, Y, uses the time machine to go back in time. For example, this human goes back ten years in time. Now, the mass of the system Earth ten years ago is now X + Y. The mass Y is being added because there already exists the mass of the time traveler in the total mass X. In essence, this is creating mass that did not exist prior. This is violating the law of the conservation of mass. Let us take this example to an extreme. Let us assume that the time machine has a high capacity and can transport all of its occupants back in time. Let us also assume that this time machine can operate at extremely high speeds (i.e. it can go back in time one time per second). Now, the human can go back one second in time, find oneself (or any other individual), and then transport two of the same individual two seconds back and so forth. So, in a matter of one year, one can be with 31,536,000 “clones” of oneself. Now take this example to the extreme with it being able to operate at the millisecond, nanosecond or femtosecond level. One could be able to create a near infinite number of “clones” of oneself, thus creating a near infinite amount of mass. This would be a clear violation of the law of conservation of mass. Mass would be created in our closed system Earth, which is an impossibility. Backwards time travel is in essence functioning as a ‘mass generator’. Backwards time travel is in clear violation of the law of conservation of mass.
Conversely, time travel into the future does not violate the law of conservation of mass. There is no net gain or loss in the total mass. For example, using a time machine or a rocket ship to go forwards in time, a human boards the device today and then travels ten years into the future. At all points along the time continuum, the total mass of the Earth remains a constant as the mass of the human being Y is moving along the time continuum with the Earth. The total mass of the system would still remain constant. Ten years from now, the total mass of the system would still be X. No additional mass is created nor destroyed and thus no violation of the law of the conservation of mass has taken place.
Conclusion: Backwards time travel is impossible as it violates the law of conservation of mass. Conversely, forward time travel is possible as it does not violate the law of conservation of mass.
