Minor point... Even if it is infinitely large it can have a shape. For instance, A sphere with an infinitely long spike, or spikes, on it.

Hmm, I know it’s a joke, but it must be the same as the speed of light... Let’s say you switch off A laser beam. The tail end of the beam continues to travel outward at the speed of light, followed by dark, which cannot overtake it. Therefore, it’s traveling at the same speed. Doncha just LOVE physics?!!

Just as I figured. A non response.

Anyway, speed of light is a convention, agreed upon by international standards.

Why? Because you can’t use two clocks, due to issues with physics and relativity. Can’t use one clock because then it is an average. An average of two legs means neither one leg can be known, but they add up to a cumulative elapsed duration.
So, being unable to determine a one way leg, the duration of either individual leg is impossible to know, except by averaging.
0+8/2=4, 3+5/2=4, 6+2/2=4 solution is 4.

Replace any speed of light system, radar, for example, with any solution for a two way duration and it works.

But, anyway.
Regards

In the old days I would turn off the tube tv and watch the light shrink to a dot then disappear slowly.

I am also baffled by the new laws of physics. Such as - If Joe Biden, a communist, a pedophile, and a pervert enter a bar for the duration and only one comes out at closing time - How can this be?

We don’t really exist-We are only perturbations in the higgs field.

“Anyway, speed of light is a convention, agreed upon by international standards.”

ROTFLMAO!

A second is convention based on the measured speed of light.

A meter is convention based on the measured speed of light.

You should get a beer for your work in this thread. Just incredible.

Look up Einstein’s opinion in 1908....
It is all workable solutions. None absolute.

I noticed you didn’t try to refute my claim that the one way speed of light is currently undetermined.

I have no idea what you are referring to.

I said you should do your homework.

Been studying.
I restated:

Question: what is the one way speed of light?
Answer: not only unknown, but undefined.

Rebut?

Now they only need to figure out God Speed.
