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. 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.

Take my GF and sleep a lot in there
Magical room with free power and Internet… I’m making it into a server room!
Wonder how it handles heat
You would be pumping your server heat into mass of water and just swapping it from time to time with cold water from lake/sea/river/whatever.
I hope it doest just has fancy cables with electric magic, but also basic human needs
- water
- light
- air
- WC
Are there any restraints with any kind of outside object your pocket dimension is anchored to? It sounds like this would be super exploitable to pull off some cleverness just as an “invisibility cloak” (although presumably you couldn’t see your surroundings from the inside, or it’d really be OP), let alone if you’re not tied to a physical object. If you wanted to, you could probably rob banks and overthrow countries with that shit.
Hotbox then some 0G chillaxin. Put that hyper-advanced tech to good use.
it’d be a great place to grow some weed.
Guns and drugs. Mostly not at the same time.
As others have mentioned - I’d use it as a hotel room and travel the world. I wonder if becoming a courier could fund the travel costs.
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 that didn’t plan to use it to trap Meruem somehow. Netero could have slapped Meruem into one of the portals.
That’s perfect for drug smuggling
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) .
Would you be able to free dive super deep taking each breath or a rest in the pocket dimmension?
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.)
Goddamn you physics
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.
You are absolutely correct. Breathing surface air would negate the bends. It’s why freedivers can go down and straight back up from 500ft with no ill effects.
The plane would keep moving while you left, so… you would come back in to empty space.
Wouldn’t the same logic apply to the planet moving?
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.
So would, like earth, or even the Milky Way. All motion is relative. Gotta define what “the same place you teleported in from” means…
2g weight room. I would train some rabbits to pull weights. Then take my rabbit beasts out after 6 months and have them pull me around town in a sled.
Slow down there Radagast.
Sounds like that compact machines Minecraft mod
You say this pocket dimension connects to the internet, a la Matrix? I’d create a game with an in-game currency that looks the same as ours, and give it the same physical properties in-game as the real currency is for the region I’m in. I then would define that I am a billionaire with a bank account to match. I teleport in, withdraw my money in cash one suitcase at a time from the ATM that has an infinite cash supply, and then teleport out.
No, it’s not simulated. It’s a real place that just connects to electromagnetic waves from outside to have internet access.
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)
I’m pretty sure this 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.
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.
Keeping the air was a mistake but I don’t see why it wouldn’t be able to go faster than c.
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
Hmmmmmmmm, now, how much energy does the box have to generate that constant 2g of acceleration? In this hypothetical the box appears to have an infinite amount of energy to generate that force though…
Yes it seems to have infinite energy but the throughput is limited to 2g of acceleration, unless you give it infinite time as well it will not reach c, though it would approach it.
Doing some calculation the final speed of 33kg, falling in 2g, for 70 years, without friction is “only” 0.9977% the speed of light.
What about quantum entanglement sending a signal faster than light?
(I’m just some schmo who watched an extra credit history series on quantum computing, so there’s every chance in the world that I don’t have it right. )
While the entanglement “signal” is near instantaneous, for various reasons no meaningful information can be deciphered faster than C.
Assuming our quantum theory, while not complete, is not wrong. We will not be able to engineer our way around this limit. A lot of funky shit becomes possible if you can break causality even with “just” information.
I thought the reason quantum theory is so controversial is because it does break causality. Like, currently we can’t decipher it, but is that supposed to be a permanent state- that quantum information is indecipherable until it would no longer transmit information faster than light?
Quantum theory is only “controversial” to the general public, mainly because we haven’t found a way to explain in simple terms things like superposition, entanglement, quantum tunneling. Quantum theory is spectacularly successful, though incomplete.
Even the “simple” stuff like the uncertainty principle takes a detailed understanding to properly grasp why there are pairs of properties that are inherently linked, and that information about one dictates how much you can know about the other. e.g. position/momentum and energy/time.
You can transmit something, but it has a noise added to it. To decode it, you need to send the readings to the other end, via normal means. Basically, the receiver can tell, in hindsight, that a message was sent, but only once its other half has been received via normal means. The best you can do is get a timestamp of when the message was sent, as well as a message channel that is impossible to intercept.
The problem comes when QM meets relativity. With instant communication, you can send information into its own past. E.g. A and B are 2 planets. C is a ship, passing planet B at relativistic speeds. Planet A sends a message to B, over the FTL link. B then sends it to C, over a normal link. C, finally sends it back to A over FTL. Due to the ‘tilt’ of C’s light cone, the “now” of A-C is behind the “now” of A-B. This allows for paradoxical situations. The maths of Relativity implies that you can’t form a closed time loop like this. Such behaviours tend to imply some deeper rule, even if we haven’t found its cause yet.
Quantum mechanics has a lot of strangeness. It also seems to play fast, but not loose with causality. E.g. objects can move backwards in time, but still obey causality. Others can be smeared over time space, but still collapse to a causality obeying state. Etc
I might be wrong, but iirc quantum theory just straight up doesn’t give a shit about causality. Where everything else requires the cause to be observable before effect (something travelling faster than light would result in effect being potentially observed before cause), quantum theory says, “why does the universe give a fuck whether or not we can see it? If it happened, it happened, regardless of whether or not we observed cause before or after effect.”
Basically as far as we can tell there there is no information traveling at FTL speed so it just works? All information that is traveling is just as fast as c or slower.
“Certain phenomena in quantum mechanics, such as quantum entanglement, might give the superficial impression of allowing communication of information faster than light. According to the no-communication theorem these phenomena do not allow true communication; they only let two observers in different locations see the same system simultaneously, without any way of controlling what either sees.” link
“In physics, the no-communication theorem or no-signaling principle is a no-go theorem from quantum information theory which states that, during measurement of an entangled quantum state, it is not possible for one observer, by making a measurement of a subsystem of the total state, to communicate information to another observer.” link
Thank you for this, by the way. I was thinking of the two entangled electrons as communicating with each other, rather than people communicating with each other through the entangled electrons, which I think makes a difference, because it doesn’t rely on interpretation, but obviously we can’t measure how or if electrons “communicate.” Is it correct that one of the limitations is in interpretation or am I reading this wrong?
Well, yes. We don’t know if the measurement we take is the result of a wave form collapse (we caused it) or the result of someone else having measured it, which would giving us the oposite value that they measured. We can’t tell if someone “sent” information or if it was the random result and we have no way to chose what value we (or the other end) gets when we collapse it.
This isn’t easy to explain over text so I’d recommend watching this video, specifically chapter “How to exploit?” as the visuals make it easier to understand.
Velocity changes how time works. The faster you go, the slower it happens.
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
It’s a really interesting question, I would love it if someone who understands this kind of physics properly would chime in!
By my understanding of Reynolds number etc, the faster they go, the more turbulent the flow, so the rocks would be constantly hitting against each other sideways, and surely grind to dust in the constantly accelerating scenario.
But maybe the infinite (looped) nature of this ‘dimension’ means that this logic doesn’t apply. What would even be the ‘characteristic length’? Are we thinking about established flow at the centre of an infinitely wide pipe? Am I wrong to think of constantly accelerating rocks with air in between as a type of fluid flow?
No I think you’re right about the fluid dynamics aspect, as we do have an indefinitely long pipe, but in the prompt the walls do still exist, so they’ll probably do create some friction. The question is, would the rocks build up some sort of boundary layer of slower flowing particles near the wall, and how much do the boundary layer and “main” center flow mix?
Thinking about it, it isn’t even an indefinitely long pipe really, as there are no “new” sections of wall coming up, instead it’s constantly passing the same section of wall, and same section of boundary layer…
If someone knows how to simulate this in a physics engine or virtual air tunnel I’d be really interested in that!
A half room full of sandstone is 33kg? 27m³ room filled half with sandstone? By my calculation it’s more like 31,400 kg
whoops, I mistook 1 m³ as 100 cm³
You can’t pull things out of the pocket without going in there first, which would be deadly in your situation. (OP says you can go in and out, and you can take things with you.)
There is an eject button for those inside to get out if something happens to you
In this case, when i die; the button will immeadiately get summoned inside the box only to be presssed an instant later
