If space is discrete, what is the “shape” of the subunit? What is the shape of the universe?

"space" is a mathematical hypothesis that doesn't exist in reality. Actual space is constructed by the relations between individuals. Our idea of space has to be continuous to describe all the possible relations.

if space is a description of all possible relations it is inherently discrete

in the sense that you cannot increment the distance between them infinitesmally

reality doesnt work if spacetime is continous, there need be a finite set of possible microstates in a finite region of space for things to happen

I think it's more of a fundamental limit, at least mathematically in physics. The energy required for a collision to probe smaller lengths than the planck length would create a black hole

Anonymous No. 16083152

That makes no sense, please elaborate, why would a planck length scale interaction generate the same amount of energy as a billion kilo star collapsing in on itself

boltzmann. say if there is a point on a line, and it can be at any point on the line, then there is infinite entropy in that system. its akin to rolling an infinite sided die; a number will never come up, there cannot be a moment

1. Reality is not made of points and lines
2. Whatever that schizophrenic rambling is, which you just wrote, has absolutely zero relevance to the discreteness of reality
Please explain why the motion of an object going from a to b would not be completely uniform and continuous, it's not "occupying every point on a line" and has no entropy related issues

1. reality is quite literally made of points and lines called particles and waves
2. im sorry your imagination has been so thoroughly bludgeoned that you cannot digest an analogy, especially one using a metaphor of dice in the context of microstates.

i am not talking about something “occuping every point on a line”, i am saying that there is no notion of entropy in a continuous system; for if there are infinite possible microstates in a finite area then there is infinite entropy.

toppest of keks
I'm not even that same anon but this is laughable

waves are waves, they are visually represented by squiggly lines but they are not lines.

particles don't even exist, they are (according to the SM which is our best model so far) excited states of quantum fields, a useful concept sure but not Reality

>>16082998
the concept of "shape" doesn't make sense in this context, a shape is the distribution of something in space, space itself can't have a shape, things that are in space can have a shape.

it would be a micro black hole, and the more energy you go above that the bigger the black hole gets
>[in a particle accelerator, ] if they can create black holes, they will have reached the Planck scale, which is believed to be the shortest meaningful length, the limiting distance below which the very notions of space and length probably cease to exist. Any attempt to investigate the possible existence of shorter distances, by performing higher-energy collisions, would inevitably result in black hole production. Higher-energy collisions, rather than splitting matter into finer pieces, would simply produce bigger black holes

if I remember correctly the ratio between earth and a proton is similar to that of a proton and a planck length.
having planck increments would "look" continuous for your monkey brain.

1. all "particles" are ultimately made of the exact same thing, there are no such things as "waves", what you describe as waves are excitations of matter, transfer of work from one part of the system to another, this applies all the way from atoms in air down to the electromagnetic field down to the firmament of reality
2. your analogy makes zero sense
>for if there are infinite possible microstates in a finite area then there is infinite entropy.
What microstates, the only place where your microstate idea would apply was if reality was indeed discrete, but it's a smooth, boundaryless manifold, there are no discrete states or steps, it's all an uniform transition from one state to another without a true beginning or end, any semblance of boundary is a mere illusion which, upon closer inspection, would reveal ever more actors taking part in the play
>>16083294
Ah, there was the misunderstanding, what you're talking about are particle accelerators and dismantling matter via high energy collisions, not reactions which occur on the planck scale naturally, of course you can't use particle accelerators to get down to that scale, because at one point there is no discernible boundary between anything and, as you pointed out, the high energy input just blasts things apart, but I highly doubt that anything interacting on that scale would ever require such input to form higher order interactions

>not reactions which occur on the planck scale naturally
I think the point is more that microscopic black holes are the limit of energy density. The more energy you squeeze into one spot in space the closer you get to creating a black hole, and when the black hole appears, instead of being able to squeeze even more energy in to that one spot, the black hole starts expanding and starts spewing out the energy you put in. This can theoretically happen naturally just as it could in an accelerator, but the accelerator would need to be a lot bigger than the LHC.

Some particles that have been detected from space are much higher energy than what the LHC produces, like this one for example which had about 200x more energy than the typical LHC particle

and also this stephen hawking quote
>Collisions releasing greater energy [than the LHC collisions] occur millions of times a day in the earth's atmosphere and nothing terrible happens

But this is purely hypothetical, observations at that scale are impossible
>Some particles that have been detected from space are much higher energy than what the LHC produces
Yes, those are also higher mass things than things at the planck scale, naturally they have more energy when they are travelling extremely fast, but things like electromagnetic waves also travel very fast, yet don't impart that much mass on things

Yeah that's right. A lot of hypothetical things have turned out to be true so far though so it has a decent chance of being real
