the things i ponder when incredibly sleep deprived:

i had a conversation with shawn (later continuing it with kirtan for a while) this morning that was quite odd.

you know, as you approach the speed of light, time slows down. if you had an analog and a digital clock would the displayed time be effected? and would they be effected in the same way? would one slow down more than the other?

and if you were there, would you percieve the time slowing down, or would it not seem to change?

discuss.

(edit: read comments if you want to watch boys throwing their geek cocks around)

but the clocks work in different ways mechanically and are made out of different materials. would the slowing of time actually effect the mechanical operation or just the materials?

The way I think of it, the effect wouldn't be noticible..it would be like Time Travel..say you put the clocks in a ship and it comes back showing they were gone for 5 mins but you were waiting on it for a week. Why would it efffect them differently if they're moving at the same speed? Wouldn't it equally effect the parts and materials?

but would it effect the movement of the parts? like, would they start moving in slow motion or would time become divorced from its physical representation?

If I've learned anything from movies it's that when you're traveling at light speed it's the same for you as it is at any other speed but to those observing, you're too fast to see :) Possibly g-forces or whatnot from actually traveling that fast could effect mechanical movement I guess, but if you're constantly traveling at the same speed would there still be those kinds of forces acting against you?

i don't believe the force goes away just because you're feeling it constantly, i just don't see how it could equalize if you're constantly moving forward. maybe you could like, adapt to the feeling of having that force upon you, but then when you stopped traveling it would suck, like when you jump on a trampoline for way too long, and then jump on the ground and it feels like your legs are gonna break because it's so hard.

KEY POINT ALERT!!!!

I just thougth I'd bring this up because of all the talk of g-forces and such.......

You'd only feel that while you were ACCELERATING!!! For those with some exposure to physics, recall F = ma (force = mass times acceleration). You only feel the force if you're changing your velocity (or direction of travel).

Think of when you're in a plane, or on the highway. You don't really feel anything once you get to a speed and stay there.

In fact, if you couldn't look outside, you'd have no idea you were moving at all!

So, once you get to your speed and stay there, even if it's close to the speed of light, there are no "g-forces" and such. You're just has happy and oblivious as a clam.

this is actually a very interesting question. the speed of light is about 3x10^8 m/s or 300,000,000 m/s or 180mi/s, whichever is easiest for you to picture. the only thing that can reach this speed would be light in a vacuum (there have recently been studies done where they have been able to surpass speed of light though) and with this speed, a beam of light would be able to circle the earth about seven times in one second.

now whether or not this would have any effect on something mechanical we dont really *know*... but i would guess that it wouldnt. the reason i would say that it wouldnt is because, well i guess i dont know. the only thing i can equate it to is going around the world in the space shuttle, you definitely are traveling at very considerable speeds that may be a fraction of the speed of light and i dont see how the speed of the object would effect a toaster... you know? either way... the toaster wont pop until the bread is done... the fact that the toaster is in the space shuttle (assuming that would even be possible of course) doesnt mean that time is going to increase to the point where the toaster would brown in less time.

that is my everyday person thought, but from a physics standpoint i realize that there is such a thing as time dilation... and though the effects of time dilation are somewhat minimal for speeds up to a half of the speed of light (c), after the 1/2c the time for the clock to complete one tick (1s) begins to increase slightly and then the time for the clock to tick once shoots up once you near the speed of light, at around 0.8c.

so i guess all that being said... its up to you on how to look at it... i'm more inclined to take the time dilation and let my imagination run with it... but again, the only thing we can get to go the true speed of light in a vacuum *at this point* is light... and until we can figure out a way to find out for sure, its all up for speculation i guess.

even the speed of light itself is kind of a touchy thing because its such a large number that many people, including some of the great minds like romer, fizeau, maxwell, etc... have come very close to determining the speed but its just such an enormous thing and from an earthly standpoint... its just really hard to imagine... you know what i mean?

i dont know if that made sense... i do ramble... i know this... i am going to post this on my journal as well, its an interesting question...
