The actual answer is
because the universe had to pick a finite number and it probably doesnt use meters as an internal measurement ruler for scaling so it's an arbitrary large random number to us.
Why did it have to pick a finite number? Because it has finite lifespan and resources for actualization. This forces hard speed limit.
The speed of light has nothing to do with light it's a shitty name that makes understanding its true nature needlessly complex.
In actuality all massless waves/particles including photons, gravitational waves, and neutrinos will move at the speed of light, because thats as fast as anything massless can go. Its a universal speed limit for any real mass-particle, which is ultimately governed by Planck's constant and the symmetry preservation of Penrose spacetime diagrams. Its the speed of causality a universal framerate limit that tells us the universe flows/computes through discrete microstates with ultimate precision limit bounds.
You seem smart.
Can I ask you a question about the speed of light? We measured it as whatever we measured it recently. As in not 13-14 billion years ago. We also noticed that the expansion on the universe is getting faster.
Is it possible that the speed of light changed since the big bang? We just assume it's the same but what if light (photons or whatever) started off slower and gradually speed up and got more efficient. Kinda like speed runners in video games. We wouldn't have noticed the changed because we measured it after it got faster. And now with the universe expanding faster, maybe light is getting even more quick.
I heard the idea on a YT video and I've been thinking about it.
He’s not
Okay then
