Put portals on two boards. See what happens if I put one board through the other portal.
Moon.
How fast would this suck up all of our atmosphere? Hours? Days?
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.
As long as I’m the first one through, the rest is set dressing.
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.
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.
Portal to the edge of the universe?
Those portals travel slowly. Good idea. Lets wait till it arrives…
- But two sheets of plywood
- Portal on each
- ???
- Profit
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”
Save it. I don’t have anything currently that I would want to use a portal gun on given that I can only use it once. I might use it to get myself out of a sticky situation, or wait to see if I ever move into a relatively permanent home and I could make a portal from my house to another location for convenience.
So it’ll be just like the bag full of Maximum Heal potions when the credits roll, except I imagine you could pass it on to someone with a message not to wait for the perfect moment.
Maybe, but I don’t particularly feel the need to use a portal gun. If I never end up using it I don’t think I’d have particular regrets, but if I used it to save my ass during a high-stakes situation then I’d be quite glad.
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
See, I don’t think water is the way to do it. I think you do it with a massive lead pole with teeth to lock into a gear.
Fully contained, no spillage
I would put one portal on a pneumatically actuated plate above a dais that holds an object, and the other portal on a plate placed at a 45 degree angle. I would then see if an object on the dais would fly or fall out of the 45 degree portal, if the other portal actuated and closed the distance between its starting point and the dais.
How would you fix evaporation I’m dumb at this stuff
Anti-evaperation field, or just let rain do it’s thing
Open a portal to the moon at the bottom of the ocean
Reverse engineer it
Nobody went with sending trump and musk to mars?
One on my butt, one in the toilet, never need to poop again!
Bonus points if someone finds the toilet 😉
You’re pooping on the oval office’s desk arent you
I mean you would still need to poop. But you wouldn’t have to worry about the time or your situation.
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
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.
Make a drain hole at the bottom of a lake, that comes out above it. Put in a water wheel, free energy.
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.
Never thought about it before, but I guess this makes portal guns impossible, since scenarios like this break conservation of energy.
But you know it’s possible from firsthand experience. Whomsth’n’t reached terminal velocity by shooting the ceiling & floor and jumping in?
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.
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…
My first instinct would be that it would equivalent to putting another celestial body the mass of the earth at the distance from the earth is from each portal. Since gravity is a wave, it, in theory, would affect a region beyond what would considered “around” the portals.
So if you put one portal on the ground, and another 100 meters up, it would be similar to there being a second earth 100 meters from the surface of the earth, experienced by the entire earth (once the gravitational wave propagated.) How that would evolve over time is too complex for my basic understanding of physics, but a simulation of it would be a neat experiment.
