Time is not a real dimension, merely a construct.....you can't grab time and move it.

You just use time to tell how far it is between events chronologically.

If something has happened, it happened.
You are wrong. Mass has an effect on time.

Time IS the fourth dimension. It is more than a "construct" as you claim.

If something is going to happen, it will happen, but, you cannot KNOW it will happen for sure until it does.....as event leading up to it can change it, etc.

There is no future to travel to, because it has not happened yet.

There is no past to travel to, because you already missed it.
It will never be possible to travel into the past, but traveling into the future may be possible.

Because of relativity, to a person who remains on earth the future has not happened yet. To an individual or body in motion there can be a time dilation because of the difference in the relative velocities between the two.

That is why travel to the past can never be possible, but because of velocity, it is theoretically possible to travel into the future.
