How are voice calls across the world instant and how do they work? How can sound travel millions of times faster than the speed of sound?

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?

Your getting caught up on the sound part. Sound travels as a wave. So does light and a bunch of other things too. Not all waves are created equal, they all move at different speeds depending on the medium they are moving through and how much energy they have. Sound waves (usually) move through air and they don’t have very much energy behind them compares to other types of waves. That is why we convert sound waves into a faster type of wave over long distances, and we moderate the material through which the wave travels. Electrical signals traveling through a wire travel faster than the sound waves through air. And radio waves through air (or better yet a vacuum) travel faster still. We can’t make the speed of a sound wave travel any faster but we can take the pattern of that sound wave and replicate it in another, faster traveling type of wave.
