If fundamental reality wasn't consistent with what? Life? If fundamental reality wasn't consistent with life life couldnt exist? Profound! — Janus

The speed of light is a physical constant, part of a fundamental reality, and has been found to be consistently 299,792,458 m/s.

If the speed of light, together with all the other physical constants, exhibited no consistency and continually changed, one day 350,000,000 m/s and the next day 250,000,000 m/s, it seems to me that life would not be possible.

I don't know the answer to your question. I don't know what fundamental reality is consistent with.

What do you think fundamental reality is consistent with?
