Portals

Okay.
Assume portals, as per the video game Portal, exist and are possible, etc. etc.

If you created one portal on, say, the floor, then another one directly above, you could theoretically fall endlessly.

Given this, would a human continually falling be at terminal velocity until starvation/death from stress?

Assume the portals have been made on linoleum dining room floor and a stucco ceiling. Would it be possible for the subject to move outside the portal to stop? If so, would the impact upon landing be enough to kill them?

Impact probably would kill, unless they shut off the bottom one and shoved a mattress under before the person fell down - might be possible depending on the distance between the top and bottom portal, most normal rooms aren't that tall though.

tl;dr: death = imminent

I'm much more interested in the possibility of giving myself a bj or tossing my own salad.

A mattress can't save anyone.  Even a pool of water would likely be fatal.  If you had a pile of cotton 100m thick, you might survive... assuming you don't asphyxiate when you can't climb out.

Is tossing one's own salad that hard?

If you've got pics, I'd love to see 'em. O_o

I'll post them on /ck/.

kk. Post a link here when you do.

I think your movement through the portals would draw air through as well, creating a sort of suction effect as air continued to rush in the bottom portal and out the other. I'm not sure how the math behind this would work, but it seems as the velocity of the air rushing through increased, it would decrease your velocity relative to the air thus increasing your terminal velocity. This would, in turn, increase the velocity of the air rushing through, I believe creating some infinite geometric series. So I guess you'd fall considerably faster than your normal terminal velocity, meaning no, it wouldn't really be safe to even touch the edges of said portal as you fell. Although this is all assuming you can control your fall enough to keep hitting the bottom portal, which isn't as easy as it sounds.

Interesting.

>>8
If that's the case there would be some friction around the edges of the portal from uhh... stray, randomly-moving air molecules colliding with the ground. This would lead to heat of course. Also if it were sucking air in, pressure would build and push back. This makes me think there would be no geometric series but just a new terminal velocity. Who the hells knows though since we can only guess how a portal works.

>>10
Pressure wouldn't build as air went in, because it would be simultaneously going out. The actual air pressure wouldn't ever change. It's much akin to running in a circle around the edge of a pool. The water gradually spins with you, allowing you to run faster, but in no spot does the water pressure change enough to reverse the flow or provide resistance, save directly in front of you.

The relevant application is to stick two portals on two walls and move the two walls close enough together so that you can fuck yourself and be fucked by yourself.  This has its own set of problems though.

Place a portal on each side of a piece of poster board, roll it up, and shit bricks.

Though I'm starting to suspect another meaning to "toss salad"...

Too bad for you this ain't an imageboard.

God damnit OP now you've got me thinking of endless possibilities.

Addressing the last questions first, assuming there is no magical force field around the portals then there is no reason to believe anything can't get out, or in. As to whether or not you would die from impact upon landing, I'd guess it would depend how long you've been in the portal for.

If you imagine jumping the distance from the top of a residential house, you wouldn't die. When jumping from the top of a very large building, you'd die before you hit the ground due to the increased speeding up, pressure from the air on your body, etc. You'd have to read up on it.

Then comes the question of gravity. Given the portal has no base nor top, the gravitational pull is nonexistant due to there being nothing to pull at. As >>8 mentions, there would be some form of suction from air etc. Assuming the gravity is completely untouched inside the portal and unaffected by the outside world (the air vortex, etc. as mentioned), then when you stepped halfway in the portal, which way would you go?

Would you step in and, due to the loss of support from one side of your body, fall down (as you would if you stepped in a pothole), or due to the lack of any push or pull in any one direction from within the portal, would you go up due to the sudden loss of weight on one side of your body?

Fuck you, OP, I'm gonna have to go get myself a doctorate in a whole range of science subjects to fully work this one out.

>>17
Gravity wouldn't be affected by portals, as demonstrated by the game Portals.

Isn't that just a poster board with a hole in it?
