Rules:

*You can teleport into and out of it at will

*It has a couple of plug sockets and can connect to internet from the region you teleported in from

*You can take objects and people with you

*As already stated, it is (3m)^3 (3m*3m*3m). The walls are plain plaster with a light in the middle of the ceiling. The pocket dimension is topologically toroidal, so if there weren’t walls and a ceiling/floor (which you can actually destroy) you would loop if you went more than 3m in any direction. Gravity, then, is artificial and can be altered to anywhere from 0 to 2g from a dial on the wall.

Edit: additional specifications

*You can only teleport out to where you teleported in from.

*Time proceeds at the same rate inside the pocket dimension

*There is an eject button for those inside to get out if something happens to you

    The amount of chaotic fuckery you could do with this…

    Driver tailgating me? Here, enjoy 3m³ of ocean water, fuckface.

    Some big religious event? Imagine the shitstorm that would happen if 3m³ of locust just appeared out of nowhere!

    Trump rally? Bees Hornets.

    “How can I use my pocket dimension to fuck with ___” would be my new approach to pretty much every encounter for the rest of my life, lol.

      This worries me a lot. Why would you want to do any of that? Write a story about that, sure. But doing it? Why? You could seriously harm and hurt people. Doesn’t sound right.

        I guess let’s pick apart each one:

        Ocean water - idk how the release would play out, but I’m picturing an opening big enough for a person to fit through, like a manhole, releasing as a stream. While a lot, I don’t think that’d be near enough to cause a hydroplaning situation, but it’d DEFINITELY get them off my ass, so win. Assuming the highest potential for harm here, all 3m³ released at the same time, yeah that could fuck up their trajectory in a way that sends them upsided down into a ditch… but if they’re tailgating, they’re already putting my safety in jeopardy, so they’ve crossed the line into me not caring if the solution does the same to theirs. Closest thing I’ve done IRL was spotting a piece of debris (chunk of a bumper or something from another car) on the road ahead while being tailgated, and I waited until the VERY last second to dodge it - the dude tailgating didn’t have time to react, so he drove right into it. Made a really satisfying crunch, and he pulled over presumably to check for damages. Lost sight of him shortly after, since I just kept going. Could it have hurt or even killed him? Yeah, if he turned sharp and started rolling or something. Could his driving habits have seriously hurt or killed me? Also yes, so fuck him: my goal is to get him off my ass, not baby him.

        Locust - Not seeing the potential for harm here. The religious nuts would be on high alert watching for fireballs coming down from the sky or rivers to turn to blood; but locusts are just big grasshoppers - not like they’re going to start hunting people down. Seeing that hysteria unfold would be great fun!

        Hornets - Kinda same spiel as the driving bit. You’ve probably seen that response to the paradox of tolerance, if not clicky. We’re talking about a group of people whose goal it is to harm/kill me, my family, my neighbors, etc. And since that’s the case, I don’t owe them protection from harm. Hornet it up.

    Man, the places I could hike without having to carry a pack! Wouldn’t need to plan for resupply or anything. Would have communication access from anywhere in the world.

    You could use it as a kickass home gym where you can dial up or down gravity depending on what you’re doing.

    Smuggling would be a whole lot easier if you went that route. Transporting all sorts of things really; you only need to get yourself to the new location.

    Could do some very amazing magic tricks since you can disappear (and swap props or outfits or whatever).

    With gravity turned down you could presumably build up some momentum and launch yourself places. Not sure how you’d stick the landing unless you can control which way is “up” as you teleport to the room.

    Edit: Just realised this idea is kinda similar to an ability from HunterxHunter

      Knov’s nen ability was such a cool idea. Using it as a killing floor for Netero to pick off the chimera one by one was brutal.

      I’m surprised they didn’t plan to use it to trap Meruem somehow. Netero could have slapped Meruem into one of the portals.

    break top

    break bottom

    insert shit ton of rocks

    set gravity to 2g for faster gravitational acceleration

    I have acquired rocks that can keep falling and build up velocity forever.

    live life as usual; when I’m old enough to near death, aim for anywhere within the planet with said rocks.

    Assuming I fill the 3x3x3 box half to half with sandstone and air; its weight will be 33kg.

    If I live for 70 years more, assuming the gravitational acceleration is 19.72 m/s^2; I can generate stones that can go up to 156.8 billion km/s (or 145 times the speed of light)

    Using the kinetic energy formula; I’m pretty sure unleashing this anywhere will be enough to destroy a huge chunk of the existing universe and in the end I’ll be the person to go out of the world with the biggest bang.

    Well, specifics about the big bang is not known; but I’ll be its closest contender if it is correct.

      They wouldn’t go faster than terminal velocity if you keep air in the chamber, and even if you remove it, they won’t go faster than c. They’ll still go pretty fast, though.

          According to special relativity, the energy of an object with rest mass m and speed v is given by γmc2, where γ is the Lorentz factor defined above^1. […] The γ factor approaches infinity as v approaches c, and it would take an infinite amount of energy to accelerate an object with mass to the speed of light. The speed of light is the upper limit for the speeds of objects with positive rest mass[…] This is experimentally established in many tests of relativistic energy and momentum.

          More generally, it is impossible for signals or energy to travel faster than c. One argument for this follows from the counter-intuitive implication of special relativity known as the relativity of simultaneity. If the spatial distance between two events A and B is greater than the time interval between them multiplied by c then there are frames of reference in which A precedes B, others in which B precedes A, and others in which they are simultaneous. As a result, if something were travelling faster than c relative to an inertial frame of reference, it would be travelling backwards in time relative to another frame, and causality would be violated. In such a frame of reference, an “effect” could be observed before its “cause”. Such a violation of causality has never been recorded, and would lead to paradoxes such as the tachyonic antitelephone.

          1 γ = (1 − v2/c2)−1/2

        Any energy lost to air friction would be transferred into the air. In a closed looped system with constant acceleration a single falling brick would eventually stir the air up into a light-speed wind.

        I don’t think the drag force due to air would work the same in a system with such a high concentration of rocks. It’s not like one object falling through undisturbed fluid, which then has to get out of the way, in this case the air would gradually start to move along with the rocks.

        This might be better modelled as turbulent flow of a mixed solid/air suspension. But there’s no ‘edges’ to the flow due to the looped dimension, so the viscous forces are pretty uniform… There would still be a terminal velocity, but much much higher than a rock falling through an atmosphere

        Also I imagine the rocks would quickly grind themselves to very fine dust, once they pick up a bit of kinetic energy, so then it would behave more like a fluid with uniform density… Could it even end up as laminar flow?

          i don’t think they would grind themselves to dust, as they’re all moving in the same direction therefore their reaktive Velocity compared to each other would be (near) 0, not giving them much energy

    Free electricity? Mining crypto with a lot of stolen hardware.

    Smuggling would be easy for reasons already mentioned.

    Murder would be easy. Teleport someone in, teleport out all the air.

    Escaping from robberies and hairy situations, likewise creating hairy situations.

    Sleeping in 0g sounds comfy, training at 2g sounds awesome.

    Living rent free on every city ever. Paired with a car means I can be everywhere.

    Huge portable storage box.

    Okay, first things first, this talk of making it my living space? Nix that. That works well enough for a single person eating microwave dinners, but I like cooking and having people over. But travel? Yeah, that would be awesome. I’m thinking:

    • Bunk beds
    • Desk with a computer
    • Very efficient use of shelving
    • Fridge, hot plate

    My only concern then becomes a toilet and shower. I guess you could move water in, but the water pressure is going to be crap.

    Long trips on planes/trains/busses would be a lot more enjoyable.

    Emergency supplies would be available at a moments notice including escape from the elements (camping/travel just became a breeze) .

      Since the pocket dimension would be sea level pressure, dipping into it for a breath when you’re deep is a sure way to get the bends, which would be a painful way to die. (Especially if nobody is there to help you.)

        Isn’t the bends the consequence of the oxygen tank and nitrogen in your blood; and if the air in your body starts at atmospheric pressure it should be fine (though no idea about the effects on the human body from such a sudden change)

          Yes. People seem to think the bends always happens on exposure to weird pressures, but it just doesn’t. I guess they’re understandably imagining it’s the same as hot or cold.

          (though no idea about the effects on the human body from such a sudden change)

          Well, enough delta p is entirely capable of squishing an entire person through a thumb-sized hole, and while there’s no hole here I image there’d still be some sort of shock wave, and the air already in your lungs returning to normal volume suddenly would be uncomfortable. Don’t go too deep the first time, definitely ease into it.

          Interestingly just 1 atm is fairly harmless. The first time someone got caught in a vacuum chamber they weren’t sure what they’d find, but the guy just got up and said his ears hurt.

          I think it was the Hitchhikers books that made that joke in relation to people inventing time travel. They travel to some other point in time and die in space because the earth isn’t in that spot any more.

            All the real theoretical kinds of time travel involve a physical path you have to move along with a specific start and end point, because yeah, otherwise the frame of reference would be ambiguous.

    This is a terrifying power, I gotta say. Like a dude could carry an entire armory around and deploy it Looney-toons-style wherever he wanted.

    I would probably just put a bunch of shelves in it and use it as a personal EDC gear storage space. 3m^3 is more than enough space to store pretty much anything you might need in a jiffy.

    There’s also apart of me that thinks putting a bed in there would mean not having to bring a date back to your place or to a hotel - but being real I’d probably never use it if I set it up like that.

      The thought of having literally every tool conceivable immediately available without having to move is fantastic.

      I’m in love with the concept of laying under my car, while also being able to get any particular tool in my hand, without ever having to get up, or having a little pile of sockets, wrenches, and bolts next to me that I have to navigate by feel.
