Wait until you learn about wavelength division multiplexing..

That's too much physics for me.
I can "almost" understand USB and firewire physics but not the technology....
totally lost

The internet is physical connections in geographical locations. It always was. People have since found ways to provide more bandwidth in less physical space, as seen by optic fibre compared to copper wire. Pulse's comment mentions a way of compacting data to fit more down the same cable at once. That's all.

What people want to make the internet comes from George Orwell's 1984, but it's always people who don't understand computers, so it will fail. I first heard there are people who imagine government will be a computer in the late 80's (a leak from within Australia's Liberal Party), before the internet, and that they didn't understand computers. So I haven't lost sleep over mad plans: George Bush's "Internets" (whom you are and what's known about you determines what information, and what edition of information, you may access online - such as the CIA's 'World Fact Book'. What idiot would let the yanks mentor their information?) to the enclosed box type controlled forums funded by the Pentagon: Alphabet, Meta and whatever else (Vladimir Putin is dying from a different ailment every week and facing a different coup every month, remember? - that's Telegram and you're stupid to join it). At its heart, it's people declaring to be true what they want to be true, not what is true. That always fails.

Yep, fitting more information down the same physical path; but doing some pretty amazing math (& yes, physics) in the middle to make it work.

At the point we're at commercialization of terabit/sec down a single strand of glass about the same width as a hair, over thousands of kilometres.

POC has us at 22.9 petabits/sec on the same technology (but with a multi core cable). It blows me away how far we've come. I remember the first fibre link I ran in my first job; 622mbit/sec over 2km. This was at a time that 56K dialup was considered pretty neat.
