As according to formula:
t=t"/(1-u2/c2)
If we travel at speed c will time for stationary observer amount to infinity?
t=t"/(1-u2/c2)
If we travel at speed c will time for stationary observer amount to infinity?
Where'd you get that formula?moatasim23 said:As according to formula:

That's the wrong formula I think (at least, it is at odds with the Lorentz transformations).moatasim23 said:As according to formula:

He wasn't asking about our time, he was asking about "time for the stationary observer".harrylin said:Anyway, if we could travel at almost speed c (we can never reach it), then our "time" will nearly stop according to a stationary observer.
I interpreted "for" in the sense of "as seen by", and he or she didn't specify whose time - that's the kind of ambiguity that is common for such questions.ghwellsjr said:He wasn't asking about our time, he was asking about "time for the stationary observer".
I asked you where you got the formula. I have never seen a formula like that even with a square root somewhere. That's why I'm asking you where you got it. You can either answer that question or you can describe what the variables mean, otherwise, how should we determine if it is correct or not?moatasim23 said:I think I got the square root missing.Otherwise the forumula is correct .Isnt it?

In any case, we cannot travel at the speed of light so what difference does it make if the formula is correct or not?
This is the formula that you linked to:moatasim23 said:http://www.salamandersociety.com/spacedoctrine/050318mathew_time_dilation.gif
I used this formula.
That's a cute phrase but it can be misunderstood. It is true in the sense that:Naty1 said:"Eternity is no time at all for a photon."
Time dilation is a phenomenon in physics where time appears to pass slower for an object moving at high speeds compared to an observer at rest.
The time dilation formula is t' = t / √(1 - (v^2/c^2)), where t' is the dilated time, t is the time for an observer at rest, v is the velocity of the object, and c is the speed of light.
According to the theory of relativity, as an object approaches the speed of light, its mass increases and its length contracts. This causes time to slow down for the object, as observed by an observer at rest.
According to the time dilation formula, if an object were to travel at the speed of light, time would appear to stand still for that object. This is because the value of t' would approach infinity, meaning time would dilate to an infinite amount.
The time dilation formula shows that as an object approaches the speed of light, time slows down. However, it is not possible for an object with mass to reach the speed of light. Therefore, time travel at the speed of light is not possible.
