No time travellers means humanity is doomed?

To travel in time you would also need to travel in space to fly to the location Earth was or is at when you finish the time travel. Earth don't sit still.

You're not traveling a physical distance as much as you are relocating yourself into a different reality matrix. So it's not as hard as you think. More like "imagining" yourself in a different context, and then actually being there (with the help of a kind of consciousness amplifier). Imagine somewhere/sometime, and then being there.

Why would time travellers dabble with the past when it could alter the future in such drastic ways? If they have travelled back in time it's only for observation and to hunt those who attempt to change the future.

Maybe the mysterious MIB are actually time travellers?

Couldn't it mean instead that everything's going to be fine, since no one is having to travel back in time to fix things?

Never mind. I stand corrected.

and yah, our Earth is speeding around the sun at 67,000 Mph....and we are also going 220 km/second relative to the center of the Milkyway.

And our galaxy itself is moving.....it's velocity is normally measured against other galaxies that it is either approaching or receding from.

Or, as the experts put it:

My (possibly mistaken) impression was that in theory time travel to the future is possible, but not to the past.

Yes that's what it means.... Our future is doomed.

If the future has time travellers where are they?

Good 1.

Best time travel I have experienced is on my 1300 scooter

It doesn't necessarily mean what you think it does.
First, some assumptions-

1)There is one universe/timeline/whatever you want to call it. When you time travel, you go to the future or past of a single timeline, no alternates or whatever

2)The universe has some sort of "timeline" protection to prevent you from killing your grandfather (google grandfather paradox if it's not clear to you why this would be a problem). Futurama represented this by having Fry become his own grandfather (i.e. doing the nasty in the past-y)

3)Time travel is accomplished in some kind of Einsteinian way, as opposed to astral projection or computer simulations or anything else.
This assumes that stable wormholes are possible.

The way it works:
Create a wormhole. If said wormhole is enterable and exitable at both ends, you only have to make one.
If it's composed of a black hole and a white hole (or some analogue), you have to create 2- 2 entrances, 2 exits, otherwise you can only travel one way. Since we're talking about fantastic things anyway, from now on we'll assume you can enter/exit the wormhole at either end and only need to make one.
Take one end faaaaar away at relativistic speed, and then bring it back, also at relativistic speed.
Due to time dilation, the clocks on the ends of our wormhole are different. One end has been on earth the whole time the other end was in deep space transit. A long time has passed on earth, not much for the travelling end of the wormhole, meaning that end will exit in the far future, and from it's point of view, the end that stayed on earth exits in the far past.

The implication of this, if you were following along, is that you can never travel into the past to a time before you built your time machine. There is no "doorway" to that previous time.

So that could be why there are no time travellers from the future. Time machines haven't been invented yet, and as long as that is the case, there will never be time travellers from the future.
