Light years is a time measure

[Strathos]

We already know how time flows at different rates based on relativity. That guy in your avatar figured this out.

No. You don't. Not far away, and even close up, there is enough discrepancy to question whether fishbowl relativity alone is the culprit for time difference!


It is easy to stick two imaginary observers at different points in the universe and start quaking about what they would see and feel!

 

[dad]

We can see time pass in distant reaches of the Universe, so it exists there.

You see it HERE!!! It passes HERE!! You never been anywhere else!!! The distant reaches may not be so distant after all, if time doesn't exist or exist as we know and experience it here!!!! ALL your distances depend on time!

Distance and time are both intrinsic characteristics of our universe.

Prove it.

Isn't this just a huge argument from ignorance fallacy?

In Germany, the cows give chocolate milk.

Don't believe me? Have you ever milked a cow in germany?

No, but my ex wife has and had many neighbors who did also.

Of course her home town was right on the French border so perhaps giving regular milk was because of the French influence.

The guy in the avatar also said believing in personal Gods was childish, go figure.

More like argument from baseless assertion.

A light year is a measure of time. Somewhat like an hourglass. If we transported an hourglass to the far reaches of the universe, for all we know, it would not take an hour for the grains to fall. Likewise, if we were there, would time even exist? If so would it exist as we on earth know it? The answer is we do not know. Therefore a light year can not be a measure of distance anywhere that time does not exist, and exist exactly as we know it here!

Without distances all of stellar evolution crumbles into dust.

Cool.

No offense, but this is at best, a philosophical argument, as there is no way to test any of your assertions. Time may well cease to exist at the outer rim of the universe, or it may well be exactly the same as right here. We don't know, and barring the development of technology to get us there, we may never know....

Nope, it passes there. We see it passing there.

Prove it.

This is the famous relativistic airplane experiment where the movement of planes through the curved space created by Earth's gravity produced a relativistic difference in time.

But they are telling it to you in AMERICA! Not in Germany. So of course, their memories are different, there.

Or perhaps they told you over the phone, and outside of Germany, the telephone signlas travel differently and change the words.

I'm quoting this post because of it's awesomeness.

I have a horrible feeling we are going to go down the "Relativity?... but it's only a theory" road.

 

[kevinmaynard]

False, actually. That only applies where time is constant! Gong.

No it is always a measure of distance.

 

[kevinmaynard]

We need not just gravity, but for that gravity to work to pull the grains down or up the right direction, so that it takes one hour. We need time itself to exist also I would think.

No since space and time are together the fact that the hourglass takes up space means there is time already.

All of this is based on the unfounded assumption that there's a germany at all!!!

Not on my part.

That is childish to say.

No way to test time in the far universe, and that is NEEDED for distance. I can test time biblical. It shall be no more as we know it now. Since earth was here first before stars, I would assume time here would be the center of time for the universe.

Time may well cease to exist at the outer rim of the universe, or it may well be exactly the same as right here. We don't know, and barring the development of technology to get us there, we may never know....

Well, then we don't know distances or size of stars. Time is an integral part of the measure used.

Excellent Watson. You do understand, then that time in involved in travel now??

Need I say more?

Yes there is. We can directly observe the passage of time in distant objects.
