Or something like that.Your past self still would have gone because what you did wouldn't affect the past, or the past self's present. The change would only occur in the future, where you are currently at.
But what's a huge plot hole for science fiction writers is where a person in the future recieves a message from the past that wasn't there before, as it must have been there the whole time due to the message being left in the past. The only way this could happen is if somebody set a timer for the object to appear at that exact moment the person needs to see the message, which would be near impossible due to the person in the past not knowing who will recieve the message.
Oh yeah, its other way around, that's why travelling into the past is impossible. After you succeeded what you went for and changed the future, there wouldn't be a reason to go anymore.

You presume that someone just wants to go back in time to change something.

Say we did have time travel.
Would we be mature enough to use it for rightful uses?
Or would we just abuse it so we could put rubber bugs in Hitler's underwear drawer?

Ok, to clear some stuff up, space is considered to be a vacuum void of matter and energy. The problem is, the universe is accelerating and it can't be explained if space is simply a vacuum. So what we've hypothesized is that there is matter (dark matter) that does not emit an electromagnetic energy (radio waves, micro waves, infrared, visible light, UV light, x rays, gamma rays, etc.) and so this extra mass that is immeasurable by us because we have no way of observing it is pushing the universe apart. Another reason the universe is accelerating is dark energy. However, dark does not mean the same thing as it does in dark matter. In this case, it simply means we don't understand it, it's mysterious.
So to sum up:
--Space has been considered a vacuum up until recently, and now is hypothesized to contain matter and energy that we cannot observe.
That's not accurate. Space is it's own self. It's not nothing, and isn't not a vacuum just because there's stuff in it. A block of wood isn't considered a vacuum, and neither is space.
--The matter we cannot observe is called dark matter, where dark means that it does not emit anything that we can measure and is therefore completely invisible to us.
Actually, the 'dark' means that not much is known about it, just like with dark energy. I actually think it might be possible that it's matter being cast like a shadow by matter in our 6-dimensional sister universe.
---The energy we cannot account for is called dark energy, where dark means that we have no way of explaining it, we simply have to say it's there in order to explain the universe.
Wrong. Dark energy can be considered to opposite of dark matter. Dark matter is a solution to the fact that galaxies appear to act with more gravity than the matter adds up to, so dark matter was theorized as an invisible and untouchable matter. Dark energy is an invisible expanding force which is among the reasons that the universe continuously increases in its expanding speed.

No it doesn't. We move around the earth with our muscles. Gravity just travels through space. Huh, that makes me consider the wave-like nature of gravity.

Technically space is a vacuum
so you should be able to create "space".
*paraphrasing previous posts C:
No. It's not really a vacuum. It's space. Space is something. We have never observed a vacuum. There IS an area, unreachable, outside the reaches of the universe (unreachable because the edge of the universe is expanding faster than the speed of light because it doesn't exist in an area with space or time and so speed technically doesn't exist), where there's no matter, and, although it gives most people, including Einstein and Stephen Hawking a huge headache, no time or space either. It's complicated.

Re: What IS space?
If you really want to understand this, I suggest reading Hyperspace by Michio Kaku. Don't ask on Scratch where we're all just a bunch of writers and computer nerds.

Re: What IS space?
Every Star Trek fan knows that Space is "the final frontier" 
But beyond that explanation...I would check out the article on Wikipedia. It's this neat site that seems to know a little bit of something about just about everything. Who knows...it might even be correct.

Re: What IS space?
But if space is where there's no matter, that means that when you go up into space, it's not space anymore.

It's like a drawing on a paper. If there's no drawing in a spot, the drawings won't feel like there's anything there (pardon the personification), but there's paper.

space is the x, y, and z dimensions, and time is the t dimemsion. time is really just space that we cannot comprehend.

Without gravity, we wouldn't have any muscles. We'd just be floating around. Astronauts have to exercise three times as much as they do on earth so their muscles won't deteriorate.

It actually is
You make a wormhole or something, I forget, but I watched this video about it.
It requires the energy of an exploding star.
That is about all I remember.
It's basically impossible to physically do (It's not like we can fly on a spaceship and capture the energy of an exploding star in a jar [hey, that rhymes!]), but if we could get the stuff we needed, it could happen!

Re: What IS space?
1) If you removed every atom in an area, you would have antimatter
2) There is matter in space
3) Fact-check stuff before you say it
