This something travelling at the speed of light c, that time has stopped for according to you , how long does it take for that something to travel a light year ?

How long it take for something to travel in one light year, is one year.

But light year is a measure of distance, not time.

The proper question would be “how far” something traveled in one light year, not “how long”.

They said time stops travelling at c, impossible or it wouldn't be travelling.

Changing points takes an amount of time.

We were looking at the limit of time for the observer, as the v of the ship approached c. Is that the limit you are saying gets closer and closer to 0?

Which observer? On earth? On another ship? On the ship in question? The answers depend on which you choose.

Hi Thermos, The limit wasn't for velocity, it was for time. As the v of the ship approached c

In the equation we were looking at, it was a limit for the observers time, as v of the ship approached c. Which turned out to be 500s per Polymaths calculation. Telling us that the limit for the time that the observer would record for that ship to get from earth to the sun, as it approached the speed of light, would be 8m and 20s. Exactly what we would expect, the same as the time for light to get from the sun to the earth.

And if, instead of an observer A on the earth, you looked at an observer C in a different reference frame as your point of reference, the limit as v->c of the time it takes for B to go from the earth to the sun would be different that 8 minutes 20 seconds, depending on how observer C moves with respect to observer A. The reason we got 500 seconds is that we were using the earth's frame as the one to compare to (the observer's frame). Take a different obsever's frame and you get a different answer (because the v will be different between A and C's frames).

Which observer? The one on the ship? Or the one on Earth? The limit is 0 for the ship and 500 seconds for the earth. It would be some other value for a different observer.

Time doesn't travel.

Time doesn't travel.

Time doesn't slow down either but that doesn't seem to bother you .

Except that we have actual observations showing that it does. Observation wins over speculation.

Hmm no, that is called timing, I have already demonstrated time does not slow down earlier in the thread. You ignored this.

But the Wilbury's did:

I'm ignoring any nonsense.

There is a perfectly good reason for that.

Well I will get my space force drive to work , good luck with your inventions.

oh my! Polymath has a time machine! He explained my post before I sent it.

 

[james blunt]

I'm ignoring any nonsense.

I did not provide nonsense , you did not think about what I demonstrated.

 

[Polymath257]

Well I will get my space force drive to work , good luck with your inventions.

And good luck with yours. If your ideas work in practice, I will happily admit that I am wrong. if they do not, will you?

 

[Polymath257]

I gave it the full consideration is required.

 

[james blunt]

If my ideas fail , of course I will admit I am wrong, but my ideas will produce something , there will be a useful outcome.

I won't hold my breath. But good luck.
