Thats why it isn't possible.
Really, this says it all.
Not if you consider that everything that will happen has already happened, which makes it impossible for you to change anything, making it impossible to erase yourself. Even if you go into the past, the time line is already adjusted for what you've done. That story that your grandfather was almost killed by an unknown assassin? That was actually you, he kills you when you go back to kill him. You exist, therefore you don't not exist.

And how would you travel faster then said light?
I would increase my speed until it was higher than the speed of light, but I don't know in what vehicle yet.
You can't, for reasons I don't quite understand, to be honest.
Basically I think its like diminishing returns on speed, and light speed is directly on the speed cap since it weighs nothing (or something like that). I think the only way you can beat light somewhere is if you could fold space, AKA teleport.
Plenty of threads have been locked because of you Mediator..... You can't always blame everything on Lahendi or MyTie. You instigate your share of drama for reasons we can only guess at......
I'll admit that's true, however I don't deny it when I get a thread locked. Laihendi is full of it if he believes the abortion thread wasn't locked because of him.
Here we go with the massless thing again, at school they teach us that photons have mass, everywhere else it says that photons are maseless, so which is it?

I don't know, that's why I said "(or something like that)".

Folding space isn't a teleport... I think it's more of a wormhole (unless teleport = wormhole).
I mean teleport as in you're going somewhere without moving through all the points along the way.

Hmm... if you could time travel and go to the past, wouldn't that be a bad idea? Lets say you kill your grandfather (I know something similar has been brought up) but lets just say you do. What I don't completely understand is if you killed your grandfather, that means you couldn't have been born (assuming you killed him before he met and had X kids with his wife) so wouldn't that mean you couldn't have been able to go back in time in the first place to kill him? Makes me wonder how that would work out...

Not something similar. That exact thing.

"time travel"
isn't some sort of new idea. in fact, seeing the future / past is absolutely possibly.
many forms of buddhist/zen/ and Indian (india / hindi) meditation can take you there.
seeing the future and past is part the path towards what they call "enlightenment"
my 2 cents.

I have a hard time understanding worm holes. I don't really think they exist.
On the other hand, time travel is possible, but not possible by humans alone. Let me explain my logic:
Let us imagine that time is a dimention. We will have to assume this for my logic to work. Let us just take that though, and go with it. In order to manipulate something in 3D, we have to have something that is 3D. You can't pick up an apple without using your hand, or some utensile. You can't move any object without utlizing some other object or force that exists in the 3D world capable of manipulating the 3D world.
So, in order to manipulate something through the 4thD, you need a something that is 4D. If you had a box that existed simultaniously in all time frames, you could utlize it to travel to any time frame. However, humans have no such utensil or utensil to create such a utensil.
This isn't saying we never will. It is just currently beyond our reach. I believe that aliens may at some point reach us using such a technology. Such a box would make it very easy to travel around the universe. Simply put it into motion in space on a trajectory that it will navigate around gravitational wells, and you will instantly have access to any space at any time, assuming the universe is a sphere, which I think it is.

popetoper said: If we could then transform our body into light particles, we could then send our body over that same light beam and travel as it were back in time. The only problem we have with transforming someone into light particles is that we have no way of reassembling those particles.
You are completely right, we can turn matter into energy (photons) and shoot them (naturally go the speed of light) and bring them to a place, and the only issue is how you reassemble them. I only see this valuable for space travel (have a ship find a planet, build a machine to assemble the object/creature that was disassembled into energy from earth). It is impossible to go the speed of light or faster from what I remember from physics, since I believe you end up with a number over 0, which is undefined, so the energy needed would either be 0 or infinite.
The way around it I believe is becoming the energy, which is possible according to physics matter-energy being interchangeable. You are turned into energy from a place of origin, like earth, and shot to another planet to be reassembled at a planet that already has been colonized from a ship that traveled to there the old fashioned way. I only see it being used for space travel though, since space ships wouldn't be able to go the speed of light, and this would shorten the time, and technically you wouldn't age while being the photons.
The closer you get to the speed of light, the slower time goes. Going faster than the speed of light should in theory send you back in time, but the energy I believe is impossible to get. Photons though, from what I remember from my high school physics book has been turned into protons, so it is possible, this not probable with today’s technology.

This is where I don't understand. I think our understanding of light travel is dependant on the time it takes light to travel. It takes less time to cover the distance, the faster you are going, not because you are changing the rate of entropy, just because you are decreasing a distance at an increased rate.

Very original point you have there... oh wait, I said the same thing at the beginning of my post on the previous page... /faceplam
No. Everything that will happen has happened. You exist, therefore you did not go into the past to kill your grandfather before you were born.
/facepalm
I commented on it before you, so if you're implying that I stole that idea from you... lol
