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....

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.
