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?

You’d be right if you were trying to shout at your friends across the globe but that isn’t how we communicate any more.
Old wired telephones worked by turning the sound waves made by your voice into electrical signals. These signals could then travel much faster than sound. Not 100% on the science here but I think we’re talking near light speed (I’ll let someone smarter correct me).
Wireless technology sort of works the same. Take radio for example.
A guy speaks into a microphone, the sound is converted into electrical signals, these get sent to a radio tower which turns the electric signals into radio waves.
Your radio antenna collects those waves, turns them back into an electric signal and uses that to create sound with a speaker.
The backbone of the internet as far as I know is a mass of fiberoptic cables, which send data as light, so transfering information at near light speed isn’t that unusual at the moment. Same principle as radio but you use light instead of radio waves to move the information.
