If you were traveling at the speed of light, you would have no mass, and thus wouldn't be able to know that you are in fact traveling at the speed of light.

Science is greatly miss interpreted.
If you travel at .999999% the speed of light for 10 years and returned to earth with the same speed. Only 20 years would have gone on earth.
If you and I left earth at the same time, But i traveled at half your speed for 10 years. We would both be on earth the same year if we returned with the same speed as we left with.
The people on earth would be 20 years older. So would you and I be.

I get all that and respect anyone's beliefs on such a notion, however without eyes, you can't see and without a brain, well you can't think, etc, etc, etc.... It really doesn't matter where you believe the "seat of consciousness" to be.
I personally believe that when you die, that's it. You simply cease to exist. This idea is very hard for the human mind to grasp or conceptualize, thus we invent an explanation that we can conceptualize.

Thats pretty bold for you to say like that, when I'm pretty sure you are wrong.
If I got in a spaceship and traveled for 10 years (to me) at .999999% the speed of light, then stopped and came back at the same speed, I would have experienced a total of 20 years plus acceleration time.
There is a time dilation factor of a little over 700X at that speed, which means 14,000 years would have passed on earth.
You aren't arguing with me, you are arguing with Einstein.

Physical matter would break down. And it would be impossible to move physical matter at the speed of light anyway. The faster you move an object, the more energy you require. To move an object at the speed of light you'd need an infinite amount of energy...and there's no infinite source of energy.

It doesn't matter who i argue with. If you travel for 10 earth years One way. It really doesn't matter how fast you travel. Because, after 10 earth years you stop. Then you turn around and travel back with the same speed. The distance is the same.
After 10 earth years you would reach earth if you travel with the same speed. Unless earth has moved away from the location you left it 10 years ago. That would mean you would have to travel a additional distance to reach earth. This additional time can be added to your traveling time, and to the time on earth. If you use a year. That means you used 11 earth years to get back home.
Time dilation is something that takes place if you were to communicate with earth while you travel. The signal would be in the past.

Time dilation – the time lapse between two events is not invariant from one observer to another, but is dependent on the relative speeds of the observers' reference frames (e.g., the twin paradox which concerns a twin who flies off in a spaceship traveling near the speed of light and returns to discover that his or her twin sibling has aged much more).

Yes i do. Do you?
If you read what they guy is saying! He has traveled at nearly the speed of light for 10 years.
If he has traveled for 10 years, how can more years have passed on earth? That is physically impossible.
Time does not speed up on earth just because he is traveling at the speed of light. Time on earth would still tick along as usual.
His time would tick along as usual. If not he would not know that he has traveled for 10 years. He would only know that he is traveling very fast. He probably wouldn't even know the distance either if he doesn't know how fast he is traveling in time.
All you actually need to use to solve this problem is this equations:
Distance = Speed x Time.
All this guy is doing, is traveling very far away from earth very fast.
To know how long time he will use to get back to earth, he can use this equation:
Time = Distance / Speed
I bet if you do the math. You will not find any time dilation at all. The time he spends traveling is also the time which passes on earth. Because if he travels for 10 years. 10 years have gone for him, and 10 years have gone on earth.

Yes your wrong about this I'm afraid, It's called Special relativity

The faster you go the slower time moves for you relatively It even works in the small speed of a jet plane, If you put an atomic clock onto a jet and send it round the world at the speed of sound it will be a TINY bit behind a reference clock kept on the ground

HAHAHA. You sure could have saved Einstein a lot of trouble had you been around to help him sort out his theories of relativity.
Here is the formula you need to calculate time dilation:
l'=l*sqr(1-v²/c²)
You are a little out of your league hot stuff.

If i was i would not debate this.
Lets retract again.
1. The guy is in a space ship.
2. The space ship travels .999999 the speed of light.
3. He travels inside this space ship for 10 years.
My question is: Have you picked the right equation from the wiki page?
You cant just pick and choose your equation if you dont know if they apply to his travel.
