in order to reach light speed an object needs infinite mass and energy and at that point time stops completely from its perspective. Time dilation slows down time, making the object move slower through time the faster it moves through space.

Once you reach light speed, time stops completely, as time dilation is now an infinite variable. But if you did go any faster what would happen to time dilation? You can't surpass infinite energy and mass, but you can increase speed, and at this point time dilation goes backwards. Anti matter is matter that actually exists within negative space-time, and moves backwards through time rather than forwards. Basically, as you speed up beyond light speed, your body would gradually lose mass and energy due to the introduction of anti energy and matter until it becomes nothing, but would continue "becoming nothing" in effect becoming a negative something, aka pure anti energy/matter. In order to pass light speed, you would need to bend the laws of physics obviously, but basically time dilation would become infinity + an infinitely small negative number. This infinitely small negative number is the anti energy created from surpassing the speed of light. As the object speeds up, this negative time dilation will increase for an infinite amount of time until it reaches negative infinity. At this point, time dilation becomes zero, which means time is happening instantaneously. Basically an infinite amount of time would pass during the "time" spent at this speed. Also, at this point, the object would cease to exist, as the negative energy/matter being created would "cancel out" the positive energy/matter effectively making the object disappear.

But suppose it didn't, for some magical reason, and continued, well at this speed there would be no positive energy/matter, and a anti object made of pure anti energy/matter would be created, starting from an infinitely small value. As it speeds up, the object would increase in negative mass and energy, and as this occurs, the object would indeed be moving backwards in time at an increasingly fast pace, which would increase until infinity, at which point the object is moving infinitely fast aka instantaneously through space as well as instantaneously backwards through time.

Physically all this is impossible because it would take an infinite amount of time and would result in matter being destroyed and created, but according to the equations this is what would happen.

This theory has been exposed several times. But now let me ask you a question: If time travels are or will be possible, why anyone did ever come here or in the past saying that he arrived from the future?

If Dark Matter truly exists, then Time Travel is possible. Since it's nothing but a hypothetical substance, The Time Travel theory has no credibility sense whatsoever.

By Dark Matter you mean Anti-Matter? Well..

was supposed to be anti matter sorry, we know that when matter and anti-matter collide they destroy each other, that's why it's theorized that they are moving in opposite directions through time.

The only explaination to me is that time travel only works in forward direction ie only to the future.

v > c implies an imaginary Lorentz factor (if you've ever actually seen the time dilation and length contraction equations, it's that term with the reciprocal square root), not a negative term for the dilated time.

It is, however, possible to get a negative time in the Lorentz transformation for a frame which is observing something traveling faster than c.

Your typical special relativity textbook will illustrate this idea with the following: suppose a signal is sent from a point A to a point B. In an inertial reference frame where the two points are at rest, the time taken for the signal to go from A to B is simply the distance divided by the signal speed. But in another inertial frame moving at some velocity v, the Lorentz transformation for the time enables a negative time for some values of v when the signal speed is greater than c - which means that in that reference frame, the signal was observed before it was even emitted.

In other words this violates causality.

Which is why this little illustration always appears as a reductio-ad-absurdum argument against the idea of faster than light motion in special relativity texts.

As for antimatter, your understanding seems to be total bunk. Antimatter is nothing more than the fact that fundamental particles exist in conjugated pairs with respect to various abstract properties aside from mass like charge and lepton number (that they annihilate has to do with the symmetry of particle interactions). Those properties have nothing to do with time dilation or length contraction.

I read somewhere there was a type of matter moving backwards through time and that is what will eventually cause the universe to collapse instead of simply running out of kinetic energy. I'm not sure what that was but that's what I assumed would be the negative opposite of matter.

Antiparticles are just particles that have the same mass but opposite charge (a few other properties too but those are more obscure than charge) to their 'normal' particle counter-part.

Antiparticles of all sorts are produced in particle accelerators all the time, and are increasingly utilized as part of technology e.g. PET medical scanners make use of the positron, also known as the anti-electron. They aren't that exotic a thing physics at all.

What you read about sounds like dark matter and dark energy. Dark matter is a real deal exotic in physics and that is partly because we have no clue what it actually is - basically there seems to be a lot more mass out there in the universe than our calculations based on what we can actually observe would indicate and we just call that unknown 'dark matter.' It also looks like the expansion of the universe is accelerating and we basically haven't got a clue as to why so we made up this hypothesis called 'dark energy.' And that is literally all there is to dark matter and dark energy.

Backwards time travel is probably impossible (very hard to imagine it ever not allowing the violation of causality).

I have arrived from the future.

So is dark matter the thing I'm thinking of that's theoretically traveling backwards in time?

I don't think we can time travel on "dreams", but eventually we can do astral projetcion and be just with our ethereal body.
But who knows? I think our knowledge is very limited yet.

And even if time travel exist, why would they came back on this time? And maybe they cant/are afraid to interfere on anything.

It's not even a theory, it's just mathematics... :| No physicists would take it serious, i
