How possible is time travel ?

Have you ever dreamed of traveling through time? maybe you could fix some troubles you did in the past or maybe you could persevere what’s going to happen in the future.But the real question is, is it really possible?

Examining this problematic requires first of all that we take a look at a major law of physics a law that changed the understanding of this world radically: Einstein's theory of relativity.

Einstein’s Special Theory of Relativity permanently tied mass and energy together in the simple yet fundamental equation E=mc^2 meaning that mass and energy  are proportional and it predicts that nothing with mass can move faster than light,we can say that the celerity of light is absolute and even the the strongest particle accelerators would only achieve about 99,9% the speed of light.Considering the previous equation we need an infinite amount of energy to push a particle to be at the speed of light and as the speed of light is considered a constant equal to 3.10^8 m/s the mass of the particle would increase massively and infinitely which is physically impossible, that’s why we could assume that the reason why this law only applies to light making it the fastest is that light is composed of massless particles which are called photons.How could we reach or exceed the speed of light?

Actually, we can’t the theory of relativity states that the speed of light is absolute and we all know the equation of speed V=D/t with D being distance and t being time.

2 particles would travel the same distance ( D=constant)

-the first particle is traveling at light speed C

-the second particle is traveling at another speed supposedly higher than the speed of light so V>C

But that’s completely opposite to the theory of relativity and C must be higher than V, what’s the solution?

You guessed it right the only possibility for V to be lower than C when the 2 particles are traveling the same distance is that the time traveled by V would be higher regarding that V and t are inversely proportional which mean that the V particle is moving slower in time.This is what makes time travel possible the key is nothing else but speed.Ultimately, I f we could manage to match the speed of light we could maybe skip 500 or maybe  1000 years into future and the phenomenon is not reversible so we can’t go back in time.
