Thread: The Speed Of Light

if time stops shouldn't it have infinite speed?[/b]

If time stops then the speed of everything is zero.

yet i have seen calculations for the exact amount of joules needed to make a ship go at the speed of light even though the ship would have infinite mass.[/b]

Those calculations will be ignoring certain laws of physics. You probably read a shock-statistic designed to help you understand the speed of light rather than accurately portray what would happen to an object at that speed.

does that also mean that there is infinite mass in the universe if there is light?[/b]

Einstein was referring to objects of mass, not waves like light. Light is not an object.

if we go faster the "C" the speed at which time stops will we go back in time? [/b]

Such scenarios are beyond our ability to mathematically model. Besides, that statement assumes certain things about time which are not certain. Our view of time is designed to help us live with time, not help us understand the true nature of it.

first of all time is reletive thus time will continue as normal everywhere else. steven hawking postulated that in a black whole the mass is condensed into no volume but infinite mass and that in the exact point where everything is sucked in time stops and thus if we threw a watch in, to us the watch would never tick, it would never move but if you were with the watch it would move normally thus on second to you is eternity to the person watching.

i understand the theory of the shock statistic and i agree with you on it

light is a wave and a particle thus it has mass because particles have mass

and i also agree with you on the timetravel senario.

could use more clarification if anyone wants to help!

But what is time? Yeah you can say that within that black hole time is going slower but is it really? At a molecular level everything is moving slower for various reasons to do with the physics of a black hole. But surely time is time regardless of what speed atoms are moving at... It's kinda hard to explain. Do you know what I mean?

And yeah you're right about the light thing, I'm not sure what the answer is there.

time is physcological.

Time ia a variability of an object (individuum). Notions of 'object' and 'variability' are
considered as initial and undefinable.

Variability of observer (psychological time) is a background, on which the time of observed objects is being projected. This statement is close to Kant's idea that time is an internal form introduced into the world by the observer (Meyen 1984).

Besides individual time there is a generalized time (or time archetype) for each class of similar objects. In particular, Meyen considers the physical time as a time archetype of the class of all material objects.

in other words time is reletive

Nah don't think i'm 1337 enough for that

But it seems to me, by what you're saying, if all subatomic particles in the universe suddenly stopped, by your definition, time would have technically stopped. Is this what you're saying? Because it doesn't seem to make sense. Suppose the forementioned scenario occurred then a human, unaffected by whatever caused all particles to freeze, was stuck in the center of the universe with everything in his body correctly functioning. All other particles could be frozen but he would still experience time.

I am immensely inept at this particular field of science and most of what I'm saying stems from knowledge acquired from the great Wikipedia so feel free to laugh at me and poke me with a stick.

Actually the 'if time stops speed should be infinite' kind of reminds me of that paradox by that ancient greek: The one with the arrow, the reasoning being: If an arrow flies trough the air, it is at a certain point at a certain time, it is there at the moment -not somewhere else-, therefor the arrow is standing still.

Total paradoxal Bull, but just poped into my mind.

For the actual question: I have no clue. All I know is, is that the theory einstein made up doens't always work, like when mixed with quantum mechanics.
