Time Travel Pt 2 - Where In Space?

OK, here's one, time travel geniuses. Let's say you time travel to another time, where in space do you end up? Most would assume in the same spot you left. But the spot you left is NOT THE SAME SPOT IN TIME!! It's safe to guesstimate the earth has never been in the same spot twice. According to some website, the earth spins 30KM a minute. That's like 2 miles. Or 80 miles, I'm a geek but I don't convert metric. Whatever, get in your car and look at the KM on your odometer instead of miles. When you get to 30, think of how far you'd get in an hour. We do it EVERY MINUTE!

The earth revolves around the sun 1800KM in a minute. We basically live on the teacups. On top of that, our solar system revolves around the Milky Way Galaxy 15,000KM in a minute, and THE GALAXY is moving 18,000KM a minute. Plus, the universe is constantly expanding so you're moving even faster. So I think I did the math right, we are moving almost 600KM a second. So if you travel through time, you are likely to end up in empty space or inside of a random star. Be prepared for that.

If there's some sort of teleporter involved, I guess you can do the calculations and figure out where in space you'd need to be at a certain spot in time, but I think at that point you might as well forget time travel because the space travel teleporter machine is probably more marketable. What's the point of going back in time to plunder gold from the ancient Egyptians and bang Cleopatra if you can just find an asteroid made of gold and bang an alien?

Time Travel Pt 1 - Changing the past

Remember in Back To The Future when Marty McFly's brothers and sisters (and himself) started fading out because he was failing? Did that make any sense?? That was the first time I really started thinking seriously about time travel.

Basically, I am of the opinion that you can not change the past. IT ALREADY HAPPENED. Some people talk about different timelines or universes or whatever. BULLSHIT. Either you're going back in time or you're not! You could go back in time to ensure that something did happen, but it would turn out that you had been there all along. Even if you managed to change something, if you truly changed it, you would only remember it as something that had always been that way, and you probably wouldn't go back in time to change it, so that creates a paradox. So forget that.

Check out Terminator, this is an example of somebody really getting it. The Terminator goes back in time to try to change something, but they only ever end up moving closer and closer to the future that the Terminator came from. That's what I'm talking about!! It turns out that he was there the whole time! And the dude they send back to stop the Terminator ends up becoming John Connors' dad! It never happened without him, BECAUSE YOU CAN'T CHANGE TIME. They were sending somebody back in time to change something, but they didn't realize that they were only fulfilling what had already happened.

I'm also a fan of Bill and Ted promising to go back in time - at a later date - and fixing a problem that they had that very moment. Why don't more people do this in movies?? Let's say I'm in a shootout with some crazy Indians (in the Wild West), and I'm really outgunned. I can plan to come back in time at a later date and give myself some reinforcements, and as long as I follow through with that, I'm good, right? There could be 100 of myself, totally shooting all the Indians. I don't have to live through a "timeline" without reinforcements, and then go back and change it, I just have to make it so that it's ALWAYS LIKE THAT.

If you would like to change something that happened in the past, it just couldn't be possible. It already happened. If you end up in some other "timeline" or "multiverse" then you aren't time traveling, you're visiting a parallel universe in a way that resembles time travel.
