Sagittarius A-Star's latest activity

Whoop.. beat me to it..

Yes. Maxwell wrote a paper about the ether. https://sites.pitt.edu/~jdnorton/teaching/Einstein_graduate/pdfs/Maxwell_ether.pdf

Prior to 1905 it was considered that light waves propagate by vibrations of an ether, which fills space, and that light moves with ##c##...

For anyone who thinks that I am gaslighting or giving a non-answer I encourage you to actually go through the work and do the relevant...

That particular rod is that particular length because you picked it. So the value is arbitrary. However, if you keep the same rod and...

I think this can be an answer to the question "Why does light move in a given timeframe along a certain number of atoms in the old meter...

Really? You think we don’t grasp the question? No, we understand what they are asking. The problem is just that people don’t like the...

Or, as I said, vary ##\alpha##, which would actually change ##c## in the sense you mean. But that just leads to the question of why...

That's because "1 meter" was defined this way. For comparison: The (dimensionless) relativistic speed of sound is ##\beta = v/c \approx...

It makes no difference if we take the old or new definition of "1 meter". Both definitions lead to ##c\approx 3\cdot 10^8\frac{m}{s}##.

There are currently 37 active Russian Rassvet satellites in orbit. https://satellitemap.space/en/constellation/rassvet Future Rassvet...

A re-definition of "1 meter" (by assigning a different numerical value for ##c## in the SI-definition) would not change physics. But it...

This would be the measurement of a distance.

Okay, I think this is a good point for me to stop and say thank you to all who have contributed to this discussion. Cheers...

For example a twin-paradox experiment (Bailey et al. 1977)...
