Tell me how mass has an effect upon time.



(Other than if you are too fat, you may not have enough time to lose enough weight, etc...)

THEN,

Expound upon -

If you travel into the future, it is merely your present at that point.

How can you have a relative velocity between an existing object or person, and one that does not exist yet?

We are all travelling forward in time...but, we never get out of the present, because, by definition, the present is when we are....not where we'll be.

If we get there...that's the present.

If the future didn't happen yet, we can't go there anyway.

If we COULD travel into the future, did we skip the past that would have occurred, and, if so, as we (As you theorized) can't go back into the past.....are we who we would have been at that point in the future if we HAD those intirim life experiences?

And if we are not, we are not truly in the future, merely a bastardized relocation of some sort.

Which is all a moot point, as its impossible to travel in time, we are mired in the present, no matter where we go.

I know there are theories, and so forth, but they are all flawed, and require things that don't exist to occur to make it work.

Its nice to call time a 4th dimension, and it is a dimension in that things do also occur in time, and if one were plot something's position completely, the time that it existed at that position is certainly relevant, etc.

We can make something move in the other 3 dimensions though, but we can only observe where in the 4th dimension it is, we do not have the ability to take an object, and place it at another time other than the present......

.......we can PLAN to HAVE it at some point in the future...but, we have to WAIT for that time to occur, for it to BE there eventually.

I can make something longer, shorter, less dense, more dense, remove mass or add mass, move it to other locations in the universe.....but, when it gets there, it will be in the present.
