Thanks for the answers guys, but I still don’t really understand how sound can go at the speed of light, and IMO I think it took a lot longer than we think.
Don’t believe me? Imagine we have no advanced tech that we have today, and across world voice calls don’t exist. Imagine how fucking difficult it would be to make the sound of your voice go at light speed across Earth.
For example imagine you’re at a park with your friend and across world vc’s don’t exist. You’re speaking to each other through the pipe with the two cups at each end, and you want to invent a way to communicate across the world
The fact they did it is awesome. It sounds impossible. And at the time I have no doubt the majority of the world thought it was impossible. But we always think it’s impossible, until it’s invented.
OP below
I always thought that the sound travels at the speed of light but then it hit me that it’s not light, it’s sound, so I had to post this.
OP above
Edit: It’s technically still sound though right? Just converted into something else.
Just because it’s converted into a different form doesn’t mean it’s not sound. It’s just sound in a different form, or it wouldn’t be sound at the other end.
Who was the first person to convert sound to the speed of light?
Edit2: I still think there’s something you’re not telling me guys 🤔😂
Edit3: to the few haters who downvoted my reply to the comment when I said ‘no shit’ when someone compared this to paper travelling at the speed of light, get a brain. Sound doesn’t weigh anything.
Edit4: u/mitchrsmert fr? If sound has mass how can it travel at the speed of light?

This indicates that the other (very good) explanations here just aren’t clicking for you yet, so let me try a slightly different approach.
Imagine that there are two people in soundproof booths, say, 100 yards/meters apart. They’re communicating over walkie-talkies. You stand right in the middle between them.
You hear nothing, right? That’s because sound isn’t traveling past you at all. Sound travels from the person speaking to their walkie-talkie, and from the other walkie-talkie to the listener. But between the walkie-talkies there is no sound traveling; it’s just radio waves.
This is why radios and phone calls never sound as good (in terms of pure audio quality) as a live performance or conversation: because you’re not actually hearing the person speaking, you’re hearing an imperfect attempt to reproduce their voice using the electromagnets in your speaker.
It’s the same as one of the reasons your cell-phone photo of, say, the Grand Canyon doesn’t look as good as actually seeing the canyon in person; your phone isn’t showing you the canyon, it’s showing you a low-resolution attempt at reproducing the view of the grand canyon.
This is why a fax is called a fax. It’s short for “facsimile” because when you receive a fax, you’re receiving a attempted reproduction based on the data transmitted, rather than the original document itself.
TL;DR Sound isn’t traveling that distance. Electromagnetic (or optical) signal is.
