Put the other portal in a geostationary space station: free access to orbit.
The single most (energy) expensive thing humans do is put things in orbit.
- But two sheets of plywood
- Portal on each
- ???
- Profit
Put portals on two boards. See what happens if I put one board through the other portal.
Minute Physics did a video on it: https://www.youtube.com/watch?v=jSMZoLjB9JE
I’m going to be really sad when I fire my first shot from my single use portal gun only to find out the surface needed to be coated with moon dust.
I mean, genuinely, this would be infinite energy. I was thinking of somehow using magnets and induction to generate power, but it would be excessively high frequency and would be antithetical to multi-phase power.
that looks just like me lol
One on my butt, one in the toilet, never need to poop again!
Bonus points if someone finds the toilet 😉
I mean you would still need to poop. But you wouldn’t have to worry about the time or your situation.
You’re pooping on the oval office’s desk arent you
I would make one portal in Tokyo or some busy city and other in another busy city and i will sell tickets to ride between the two. Or i will put them on some sheet of something that i can move so i can change destinations but in game if i move the surface under portal it will dissapear
I will nationalize your service for free to everyone
Make a drain hole at the bottom of a lake, that comes out above it. Put in a water wheel, free energy.
Never thought about it before, but I guess this makes portal guns impossible, since scenarios like this break conservation of energy.
Maybe conservation of energy is wrong.
Well, the videogame kind are definitely impossible, but if the gravitational field could travel through the portal then it would probably still conserve energy. The gravitational interactions around vertical portals would be exceptionally weird. If they were close enough, you’d probably experience weightlessness while in between them, but I can’t wrap my head around what would happen as they move further apart. That makes me hope someone tries to make a mod that models that in Portal…
Maybe entering the portal takes as much energy as it would take to climb the long way? If the other end is on the moon you have to enter at 10km/s or something else you fall right back out. Warning: I am not responsible for damage caused by extreme tidal forces.
But you know it’s possible from firsthand experience. Whomsth’n’t reached terminal velocity by shooting the ceiling & floor and jumping in?
The trick would be finding the tallest vertical line of sight you can. Just making portable plates and flying one would be hard to beat, but failing that maybe a mineshaft.
Does it fire through water in the game?
No. The only water in the game is toxic (i.e. you die if you fall in) and you can’t fire the gun through it.
There are no bodies of water but you can shoot through a falling stream of it.
One at the white house, one at the sun.
Be carefully secret service is now on to you. Maybe add /s so they know you’re joking and not intending any harm to dumb animals there
He meant to say “In portal”
Moon.
How fast would this suck up all of our atmosphere? Hours? Days?
Probably years, if not more. XKCD’s “What If?” has a nice explanation on a similar question, but in that case it was a portal at the bottom of the mariana trench and the question was about draining the oceans. The answer is that you probably wouldn’t notice in all your lifetime.
I remember that video, but I‘m not sure it is comparable — air might flow faster than water [citation needed] and there might be less of it [citation needed].
there’s more water than air (mass-wise).
Above you, atmosphere scale height is 8 km, with a density of 1.25 kg / m³.
That makes 10^4 kg of air above your head per m² surface area.
To get the same mass of water per surface area, it would only have to be about 10 m deep. But the ocean is kilometers deep in most places.
I’m pretty sure there is much more air. At least volume wise. Sphere volume goes up by radius cubed.
Pretty sure the game theorists channel on youtube did that one several years back. It’s been a minute since I watched it but a search should pull it for you.
This one? https://youtu.be/0Hwjmek0Uvw It more addresses survivability in space, but unfortunately not the „drain earth of its atmosphere“ thing. Then again, in game the portal was closed quickly again.
Unless the pressure differential causes it to escape the moons gravity well it would probably stabilize at some point before dumping the whole atmosphere, right?
Easy solution for that, you fire the earth portal on a wall inside some sort of specially constructed airlock.
That hard part would be getting the moon portal in a useful place, you’d probably need to go up there and find a good solid cliff face or something. On the plus side having done that you could be home again in a few seconds.
As long as I’m the first one through, the rest is set dressing.
Portal to the edge of the universe?
Those portals travel slowly. Good idea. Lets wait till it arrives…
Open a portal to the moon at the bottom of the ocean
I’ve always wanted to fuck my own ass.
Won’t work, as you thrust your ass will pull away. Only way I could think of is having the portals on platforms that would move with you.
I appreciate your in depth analysis of this situation.
Uhh huh huh… you said depth.
Or potentially, you could just move one of the portals relative to the other.
Maybe it would just double the friction.
Take advantage of the free energy and build a power plant around it.

Reverse engineer it
