really, two somethings that relate to each other,

1. time dilation. according to wiki the amount of time a a round trip will take relative to the observer is t = 2d / v where t=time, d=distance, and v=velocity. the part I don't get - v = d/t right? seems like a circular definition to me


2. flowing from time dilation - if you move at the speed of light time stops... this implies to me that if your velocity was the speed of light then it would take absolutely no time to move from one point in space to the next. if you are not moving through time at the speed of light then velocity would equal distance divided by zero... and nothing can go into anything infinitely, therefore your velocity is infinite.

this is seriously fucking with my head, could someone explain this to me? and please don't go too terribly crazy with the math. I can take some stuff, but not a 5 inch string of numbers mixed with symbols I don't know the meaning of (I didn't take anything but algebra 1 so I don't know a lot of stuff. I could understand it but I hate pointless repetition of formulas so I hated math class, so I didn't go advanced with it, but I do like math.)

anyways, some explanation or a link would be cool, as well as any discussion, including the miracle of magnets.

Congratulations. You have just discovered why travel at the speed of light is impossible.

If you want to learn about time dilation, look up special realativity first, Lorentz transforms (for observers moving along a same axis). And you can't travel at the speed of light, that's the problem.

First thing to realize, is that you can never travel at the speed of light. It's impossible. You simply cannot do it - you can get close, but you won't hit light speed. Second, if you could get close to light speed, time would slow down for you. If you were moving at the speed of light, I don't think time absolutely stops. Look at how long it takes for light to travel from the sun to our planet.

Travel at the speed of light is possible, the problem is that if an object has zero rest-mass (main problem) would require an infinite amount of energy to accelerate to that speed (secondary problem).

If you do believe in special relativity there are several string theories that postulate the ability to locate and ride particles already accelerated to the speed of light.

Unfortunately causality and absolute relativity must be abandoned to make this possible. If you're looking into dilation of time there are regions of space that are "warped" and believed to harbor faster than light particle actually moving forward in time, unlike tachyons.

holy shit, since when?


also, no, it's not for homework, i just like to think about stuff like this.

if the speed of light is impossible, then how does light travel at that speed?

Ive been thinking about our ideas on space and time a lot lately. Isnt it kind of bold for us to say that nothing in the entire infinite universe can exceed the speed of light when we ourselves have never even been beyond our moon?

Ok well ill take a whack at it. The faster something goes, the slower time passes.

If you are in a ship going Speed of Light then time outside of the ship will seem to go faster.

Even at substantially lower speeds than speed of light. The satellites that we use for gps actually fly fast enough that the clocks on them must be set differently.

Light itself still takes an incredibly long amount of time to travel through the universe. While traveling at light speed will make your perception of time outside of the ship faster over time you will still age.

Fly at the speed of light and come back to earth after a year of flying at the speed of light and time will have advanced on earth more than 2 years.

I learned this over the course of Year 12 Physics at high school. To do so properly would take roughly 1 year.
