Without reading the twin paradox (which I will do shortly) I'd disagree... Even while travelling at the speed of light, it would still take time to arrive at your destination.... Light takes 1.1 seconds to reach the moon from Earth and around 8 minutes for the Sun's light to hit the Earth. The only way you could arrive at a destination without taking any time would be to travel at infinite velocity, or to simply teleport.

 

You miss understand, from the point of view of the traveler he would have arrived at his destination at the same moment as he left if he were traveling at the speed of light, from an outside perspective however the traveler would take time to reach his destination but he'd be the exact same age as when he left.

 

You must read the twin paradox...

 

Later I'll explain Quantum Mechanics and String Theory if you want.

K... I skimmed thorugh a bit of the Twin Paradox and got the just of it, but they don't actually explain why you supposedly age less while travelling at near-light-speed! The rest of the arguments make sense if I blindly accept that, but I can't just do that now, can I? I'm just having trouble understanding where the claim of aging slower at light speed comes from, and if you have to invoke quantum physics to explain it, so much the better hehe.

 

BTW, I was reading this for my Twin Paradox lessons:

What about a black hole? I thought that closer you get to it, the slower you seem to go from someone's elses point of veiw, but it seems to you that your traveling at ordainary speed.

It utilizes the same principal except applies it to gravity. Say you're accelerating in a spacecraft at 9.8m/s/s what do you feel like? Well you'd feel like you're standing on earth, therefore no experiment can be performed from within a closed spacecraft (Without windows) to prove weither you're accelerating in space or are under the affect of gravity. Einstien therefore said that gravity bends the fabric of spacetime and enables it so that a massive gravitational field (A Black Hole) displays the same effects as moving at a relativistic velocity (Near the speed of light) with time dilation.

 

You're going to have to read some of the other thought experiments to get Einstein's drift... To summarize however Relativity can be broken down into a number of simple laws.

 

1. The speed of light is the only constant in the universe, and no force even gravity can act instantaneously.

2. The speed of light cannot be surpassed due to the fact that to do so would require an infinite amount of energy.

3. Clocks (Biological, Chemical, Physical) slow down as you approach the speed of light.

4. Mass increases as you near the speed of light.

5. Length and distance contract as you near the speed of light.

6. Gravity creates the same effects as velocity on spacetime.

 

I'm paraphrasing, but thats basically all of the ones I can think of.
