What about when you cut the nurotoxin tubes?

Whenever you place a portal on a stationary surface and it begins moving, the portal dissapears. Yet if you put it on a moving surface, the portal stays. I take it that when you paint the portal on a surface, it will remain there until a change in the relative velocity occurs.

above that, if u place two portals near to eachother 2 both universes the portals lead to will be destroyed.If they lead to the same world u get 2 dimentions - same thing ,they are just destroyed

Yes they can. In Portal 2 you place portals on moving tiles and use a lazer to destroy some pipes to the neurotoxin machine.

Portals cannot stay on a surface which has a changing velocity. The moving platforms in portal 2 stay at the same speed the entire time.

What about the Moon?

You sir, deserves cake

That white gel you place portals on in the game is made from ground up moon rocks. Henceforth, the moon is a portal-able surface.

but the moon moves

You raise a good point, however the velocity of the moon does not change at any point in time, unless the gravitational pull of the Earth suddenly shit it's pants and had to go the the bathroom for a while, leaving Earth gravity-less.

but isn't velocity a vector quantity and therefore change in direction affects it? (moon orbiting around the earth)

What about it?

Mh, what to say in my defence? /: ...um... I didn't make it!

You don't need a defense. That guy is totally bullshitting you.

Mh. I'm just gonna stay dumb and slow for the rest of my life.

S'alright. Happens to everyone.

just saw my future self...thought he was gonna get away with making me look stupid!!!!!well I killed my future self and since I (or none of you all) have believed what he said, time in itself is safe.....

SHUT UP AND ENJOY THE SLIGHT MINDFUCK!

Bullshit. You know nothing of portals.

portalception

what the hell is that

SON!

If that's the baby....who on this planet would allow the people who made that to mate????

What in gods name has science done?!

Jackyyyyyyy?!? What have you dooone?

the portal is not active until it hits a flat compatible surface... otherwise it wont work. and the portal moves according to and with the surface around it. once the surface is no longer flat the portal disappear.
