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

I hope it doest just has fancy cables with electric magic, but also basic human needs
- water
- light
- air
- WC
spend my entire life trying to fill it with poop
With Poop alone it might be difficult - It would take around 200-400 years to fill that with poop alone, so it’s more of a multi-generational project.
But if you also use urine it’s much faster - Urin alone is doable in 42 years for the average human.
Can I take one end of a cable with me?
What’s the max power I can get from the sockets?
Where does the eject button dump people and can it be set to dump things other than people as well?
Does time continue inside the pocket dimension if no one is inside?
What’s the internal temperature/humidity? Is it regulated?
Can I choose what I take with me, or is it just everything im wearing/carrying?
Questions aside, I would fill it with all sorts of stuff that I might need at some point, but leave enough space for a bed and a desk.
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.)
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.

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.
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
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?
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
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.
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?
I’d probably use it as having a lot of extra portable storage space, so it’d probably get filled up with a bunch of junk real fast. also I’d have the coolest battery pack
