The guys form the physics department of the University of Nottingham talk about Portal 2 and, wormholes and the physics behind all this:

Very interesting video. Thanks for sharing this.

A block of pure solid geek gold! It's pretty interesting to watch. 

haha dude is PUMPED

Being a physics student I find this kinda stuff fascinating and I've thought alot about the science aspect of Portal 2, pretty good video

Was he playing Portal 2 with the touchpad on that laptop? Oh dear.

So what I get from this is the portal gun harnesses the power of a billion stars. Yay science!

Wow, inteesting shit. Tried to study physics up until university but was pretty hopeless at it!

Poor guy, he can only play the game at like 10 frames per second.

So they aren't making repulsion gel?

Well as they say, if there are time paradoxs to time travel, it's simple, there are two of you there, doubles. Also since you can change things, creating a time paradox, that means there are alternate universes at the same time with different scenarios like the t.v show sliders. So in a way, it might be possible and we should disregard the term time paradox and use alternate universe. They are only limited to 4th dimensional thinking of our known universe. But still cool video.

nice video. thanks for sharing.

Dude is super stoked about the recoil on the portal gun.  It would probably break his heart if you explained the concept of animations to him.

From a gamer's perspective I'm cringing at how he's playing with a touchpad at what looks like 10fps. 

Amazing! Thanks for sharing, duder!

Whoah the fps was LOW on that laptop.

But a very interesting video indeed.

The way he got excited about movement of your character or the recoil of your gun kinda freaked me out at the end.

I'd love to see these guys talk Noby Noby Boy.

Why they skip maths?

This may be the copious amout of alcohol I've drank tonught, but this video blew my FUCKING MINF!!!!!
