We cannot because the faster an object moves, the more massive it becomes and the more massive it becomes the more energy is required for it to build speed. Simply put, collecting enough energy to go the speed of light is just out of the question.

I always wondered about this... if your statement is true, then why can't we see photons? They travel at the speed of light.

Because theoretically. photons are massless particles.

Had you said something along the lines of an adrenaline induced psychological interpretation on the individual perspective of time, I may tend to agree with that.

That is exactly what I was trying to get at. Forgive me. I just was not sure how to word it. I felt like I was beating around the bush but just was not quite saying it right.

As for using the word "shut down" that too was a "for lack of a better term" type of thing.

That said, I think that would explain why time seemed to slow to a stop when that wreck happened for you.

Again I do apologize for the horrible wording I used. Anyway, You have me wondering now, if you already knew the answer to why time appears to stop during traumatic events, were you perhaps getting at something else that I did not catch?

I am really confused on the theory of light travel + time.

Seriously help me out with this,

If you are able to travel the speed of light, 10 light years at the speed of light is still 10 human years because you are traveling at the speed of light you do not slow or speed up time just distance traveled in the same amount of time.

If you travel at light speed on a set distance of 100 light years away, guess what your going to die because your well over 100 years old. The people back on earth are not exponentially older than you. they aged the same as you did. just because they are moving at human speed and you are moving at light speed, time does not change only the distance from you and the other people change.

Distance is only traveled faster it does not equal the speeding or slowing of time, but how fast you can travel a distance. So ultimately your only saving time that would have ultimately taken lifetimes to traverse and found a way to do it in a life time by going at a higher rate of speed. respectfully if you travel a distance that is on par with human life

So again, your not slowing or speeding time up, your ultimately saving time...

A second is a second regardless of how fast you go, distance traveled is the only thing affected by speed.


Examples;

Ok. say you need to go 60 miles, you get in your car and drive at a speed of 60 miles an hour and reach your destination in one hour.

1 hour passed for you and 1 hour passed for every single person on this planet.

now you get in your jet and travel the same distance of 60 miles, this time, since your speed increased it only takes you five minutes, still five minutes passed for you and every single person on this planet.

now you get in a vehicle that is able to travel light speed and travel the same distance of 60 miles, you will get there in 11,160,000th of a second, 11,160,000th of a second would pass for you and every single person on this planet. Time remains constant.

I have seen the videos where they show the two mirrors with the green laser bouncing between them and I feel that is it flawed for the same reason I stated above.

The green laser seems to move slower its only because you are moving so fast that your now seeing that laser on a 186,000 m/s second scale because of how fast you are going.

Time is constant, speed is relative...

Again I am having trouble wrapping my head around the theory.

Ive always wondered about the danger of going BACK into time. Would the "craft" or materials utilised to get there still theoretically be in existance as they havent yet been invented yet. It'd be the same as a undiscovered Metal from 1000 years just suddenly appearing on Earth this very second, even though its not been found yet.

my thoughts on this:....since matter can't be created or destroyed, i don't believe that this would be an issue. as long as those composites are in existance (and they are, even if they haven't been "discovered" or combined yet), then you should have no problem with your vessel.

...keep in mind that i am only an aircraft mechanic with limited education, so this is just my opinion

I've always considered time nothing more than the movement of matter/energy. No movement= no time and so forth. So maybe a gravity distortion wave would distort or stretch the movement of matter/energy, therefore affecting "time".

great article. but the question i have is, will we ever use "time travel" as a means of traveling to other states/countries, almost like a teleport type means?
