and I even love the other cool hypothetical stuff that mostly lives in science fiction,

like wormholes.

Wormholes are a funky but possible solution to Albert Einstein's famous equations for the

theory of general relativity. These theoretical cosmic portals can shorten a trip from hundreds of

light years to minutes. Wormholes have been a mainstay of transportation in movies like Interstellar.

That's it. That's the wormhole.

And TV shows like my favorite, Star Trek.

The aliens who live in the wormhole, as you call them.

Which Ron Campbell says is not far off from how scientists think about these wormholes.

It's very much like a bridge.

You can do this thought experiment yourself.

You take a sheet of paper.

You fold it kind of like in half and you poke a pencil hole right through the middle.

And that is essentially a wormhole.

It connects two points in space and time together.

Ron's a theoretical physicist, and he wrote his PhD on funky solutions to Einstein's

equations for general relativity, like wormholes.
