Now, YOU'RE thinking with portals.

Right now, I would put on in the floor next to my console gaming chair and one next to the wall in my keyboard so I could press my vent hotkey and yell obscenities at my friends.
i wanna know what would happen if you shot someone with a portal gun... would the be stood their with a huge feckin portal attached? or would they just transport through the other portal instantly? or would it just crush them?
But mostly on peoples cielings above their bed so you could freak em out. Say some crazy prophetic shit and then close the portal. As long as they don't know about the portal gun it'd be a blindin prank.

Here's your problem, the portal doesn't float in the air, oh no, it stays attached to whatever surface it is shot onto. That's why you can't just make a portal in midair.Zetim said:

What I would do is take it out into the world, and mess people's sh*t up. I can say that, right?
I'd put one portal under a rug, and another on the side of a steep cliff.
"Hey I got your-AHHHHHH!"

You could go parachuting WITHOUT a parachute! Just shoot one onto the ground somewhere flat, shoot the other directly below you. You fall through and go up the other, then fall back into it and go up your original path...I tried this in the gigantic room towards the end, I jumped from the catwalk. Each time, you don't go as high, so eventually you could step off safely.
Physics:
Every time you go down X length you gain Y speed. And every time you go up X length you lose Y speed. Thus, you'd think that you would never slow. However, the air resistance decreases your speed when going up OR down. So every time you went down X you'd gain Y - DRAG speed, and every time you went up you'd lose Y + DRAG speed. Hence each cycle would slow you by 2 * DRAG.
Note: I find that the magnitude value of speed is easier to use than the vector value of velocity when dealing with portals. Also, although the game says that MOMENTUM is conserved between portals, that is incorrect. p (momentum) = mv (mass * velocity), so p is a vector. When you go through a portal your direction is changed, thus p is changed. However, it is correct that the magnitude of p is conserved.
Also, Portals would have to use alot of energy, otherwise they'd break the conservation of energy with all these perpetual motion ideas. I think that energy would be used whenever an object is transported.
More Physics:
Kinetic energy of object is not an issue. E = mv^2/2, and so E is a vector. When the object goes through all energy is converted from E(old direction) to E(new direction), so no additional energy is needed. This is one of the two functions that completely describes portals - translation of velocity direction and translation of position, which follows:
The issue lies in potential energy. An object at 1m above sea level has much less gravitational potential energy than an object 10m above sea level. Hence, the portal must supply the extra energy.
Only a little more physics, I swear:
One thing that must be considered is the fundemental nature of portals. Do they use wormhole technology? Do they, like the teleports in HL2, rely on entanglement? Or do they work more like the teleportation technology in some SF where it analyses you, sends the info via EM to the exit portal, and then that reconstructs you? Or something else?
The first two options mean that portals are FTL. This means that, by Einstein's Special, you could use portals to travel back in time. However, there is some confusion as to whether that applies with wormholes and the like.
Just thought this might be interesting.

Look, noone knows how the bloody things work, they are just sweet like that. As for your physics, they still wouldn't slow down every time, because the air resistence doesn't amount to greater than the initial velocity so you're still going to gain speed, up until terminal velocity.ekimekim said:
Now, if you were to do the teeter-todder thing where there are 2 holes in the ground next to each other, then I could see a loss of speed, cause some energy is disspersed in friction and the such. But a straight fall down will make u go faster.
As for wormholes...I got not'in'.
Also, the portals defy said physics, in the sense that they teleport you to a different place, while conserving energy in a direction.
What's really fun is that, in an infinite portal loop, you can look up or down, see yourself, and actually shoot yourself through the portals and kill yourself, something with which I had much fun.
I'd be a superhero. It's a way to move over the rooftops of any of the tallest buildings, can simulate flight, you can teleport 'baddies' into the sky and portal them into a police car. And of course... you could get yourself some cool looking tights that match the colour of the gun.
Those dye packs would only go off if you go through the front gates, they send out a signal, and 10 or so seconds later, the packs blow.xbeaker said:Bubble Six.. you could use it to rob a bank, sort of. You set up a portal at home (in the shower ideally.) Walk into a bank wearing a good mask, packing a portal gun, and a regular one for good measure. Rob the bank for all you can get. When the cops show up, you portal out of there. Then open a fast portal of the same type to close the one you left at the bank, clean and simple.
When they dye pack blows... well, that is why I said to set the portal up in your shower
