Oh, so all we need is an impossible material. Obviously!

Wow, this looks fresh off the VHS original!

Scientists... always asking how to do a thing, never caring if we SHOULD...

That would be nice if they'd actually got around to explaining the full process.

You are not allowed to make up your own rules to this game!! This is pretty pointless info. I think someone was just having fun with a rendering package.

"Is this it, is this a sphere turning inside out? You bet!" No, no it isn't, it's just a poorly done animation that demonstrates nothing.

That's no problem for a mathematician. They barely admit the real world exists, and it holds no constraints on them whatsoever.

Punchline for an old joke about opening a can of beans on a desert isle:

Economist: First, assume a can opener....

Man, this is some bullSHIT

An engineer wakes in the night and finds his waste basket on fire. He grabs the biggest bucket he can, fills it with water, and dumps it on the fire. He makes a mess. The fire is out.

A physicist wakes in the night and finds his waste basket on fire. He does a quick calculation of how much water is required, measures it approximately, and dumps it on the fire. He's pretty neat. The fire might be out.

A mathematician wakes in the night and finds his waste basket on fire. He grabs a pencil and paper, satisfies himself that a solution exists, throws the paper in the basket, and goes peacefully back to sleep.

I found a longer version of the video which elaborates further. It's not really about engineering something useful with actual materials as it is a mathematical wizard theory. Who knows what applications it could have, plenty of things that seemed next to useless suddenly find real world applications years later: https://www.youtube.com/watch?v=sKqt6e7EcCs
