Please correct me if i am wrong about what i am about to assume.

If it was possible to travel forward in time, this would mean travelling to Earth at a location in the universe, that Earth has not reached yet, due to the expansion of space.

So therefore time travel could only work if you are actually going back in time but never forward.

Am i correct in this thinking ?

I've pondered this myself to the point I'm gonna have a seminar on it last thursday.

Be there.

A very select few of us can go forward and backwards in time.

Want proof?

I'll go back in time a couple of minutes and post on this very thread!

Helps with alibis and such.

Whoa.

Now let's see you go FORWARD in time and post again.....

Depends

if you’re using a time machine you can’t go back in time before the machine was invented .

Well I'll be damned.

Would it not depend upon the speed at which the "time" travel occurred?
Light Speed? Faster than light?

Hmm. Maybe time travel does work. Its just that everyone who has tried it are just floating around in space where the earth either was, or will be.

Famous last words, "well, this just sucks!"

Suppose you first send another time machine back in time.

My thinking is that the expansion of space is a " constant " that cannot be manipulated.

Surely you cannot go forward to a point that the universe has not reached yet ?

If I had a time machine I would’ve seen that one coming .

It's more like the opposite, we know it's possible to travel into the future by orbiting the Earth at a high velocity due to time dilation, but we have no proof that traveling into the past is possible. However it could be possible if the many worlds interpretation of QM is correct. The same problem that you mentioned applies to time traveling into the past because the Earth was at a different location in the past.

If you're traveling to a future, then the earth in the future will be at that point that you are traveling to.

If I travel 100 years ahead, then when I arrive, earth will be where and when I traveled to.

You can throw a football to a point that the receiver has not yet reached.

Just additional calculations as to speed and where that point in space will be when you intend to reach it.
