I've read (in regard to the UFO subject), you can go back but only as a viewer. Impossible to change that which has already happened. Think about it. If you now say something , it is said. Going to the past or future will never change that. If it could be changed, then in reality, nothing is reliable, nothing makes sense and if you mention multiple universes..could be but I am only interested in the universe I am in, not others.
No.
Time is space. You may be in only one space. To occupy another spot, either near or far, takes a finite amount of time.

Time is not space, time is a virtual yardstick to compare the rate that forces can act on matter in space. That yardstick is affected by the underlying fundamental structure of space which is unobservable and unknown.

Single atoms vibrate in free space at a fixed rate. One such atom is caesium 133. One second is equal to 9,192,631,770 of these oscillations - that is the defintion of time. One minute is equal to 60 times that many oscillations, and one hour is 60 times that, etc...

Everything in our existence is measured by how many times that atom bounces around. If space had different properties it would bounce differently and hence time would also be different.

Time travel is not possible, at least travel to the past. How do I know? Simple. And I won’t use a bit of science to prove it. Just logic.

If reverse time travel were possible then we would have to assume that at some point in the future, we would invent the machine to travel in. If that machine is invented in the future, for all time after that reverse time travel would be possible. That gives us almost infinite possibilities to observe future time travelers amongst us today and even all throughout history. We would virtually be tripping over future time tourists visiting us today. And with infinite number of possible visitors, there is no way they could keep it secret what they are doing.

Put simply, if time travel were possible, it would be a common occurrence to meet future people every single day.

As you approach the speed of light, time (and space) flow approaches zero and mass approaches infinity. Theoretically, there's not enough energy to make an infinitely heavy mass move any faster than the speed of light.
Canít do speed of light, but what about half the speed of light?

That logic assumes the human race survives long enough to find that way, or that they will find it all. Not find it does not preclude its existence. What precludes its existence is that its completely nonsensical. There is no time, there is no "then" and "now" there is only "now". The past isn't a different place, it's the same place after matter has moved around.

Since all things exist only in the present (Now), time cannot be real except as a self-conceived illusion which is supplied by our consciousness as we co-create this physical reality dreamstate. Hence, 'time travel' is a misnomer.

Well, there is a theory that what we call 'ufo' sightings, these may actually be time travelers from some distant future.


It would explain why there is never any contact or landings, they pop up, stick around a few seconds and then gone. It would also explain why 'ufo technology' always seems to stay the same, over decades and centuries.

Yes there's no such thing as a time-traveler, except in the case that we are all traveling through it at exactly the same pace. One second at a time.

The chances of a human traveling at a speed great enough to experience time dilation in relation to a still human being would be so remote that any number of things would stand in the way of anyone being in this scenario:

- Speed not attainable on Earth and survive
- Not sufficient time to prove any meaningful phenomenon as the receiving radio would have to adjust its frequency band in a measured, calculated sweep to capture any intelligible message, the signal would likely just be missed or appear as noise / blip
- People are enamored with time travel, but the reality of it is just not as it's popularly romanticized.

Super speed may not be the only way to achieve this though.
