The train analogy helped, thanks. I read about the light shift before but comparing it to sound clarifies it.

That makes sense. Thanks for the response.

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.

Caesar salad is just another thing that the white man stole from a person of color. Now everyone thinks it was Julius that made the salad instead of some rando from Mexico. What fools we have become.
