Does planck length mean space is pixelated?
No. All it means is that there is a smallest length that can be measured.
No. Planck length and other Planck units are only intended as dimensionless units. There is nothing fundamental or elementary about them.
>>16537060yes. everything must be pixelated for it to exist.
>>16537060planck length is a theory only...
>>16537070>measuredWhat about formed? How can something that can't even be measured have a consistent form?
>>16537098>length>dimensionlessWut?>1.616255(18)×10−35 m>dimensionlessHuh?>fundamental or elementaryThe fundamental elementary components of planck length are the the universal constants G, h, and c.
>>16537098>There is nothing fundamental or elementary about them.They indicate the point where general relativity can no longer be realized as an effective quantum field theory and you need its UV completion (strings, LQG or something else) to interpret what’s going on.
Possibly. But since general relativity is a thing, it's not simple pixels.
>>16537060No: observations of optical aberrations from the most distant stellar objects are inconsistent with pixelation at the planck scale.
>>16540184>They indicate the point where general relativity can no longer be realized as an effective quantum field theory Speculative >you need its UV completion (strings, LQG or something else) to interpret what’s going on.Schizo.
>>16540088>h>universal constant LOL
>>16540085We don't know anything about form. We know what we can measure.
>>16537515Planck length isn't a theory, its a constant derived from other natural constants. There are multiple methods to derive planck's length and give it meaning. >>16537060It doesn't mean it is "pixelated" but it could give rise to the idea that space and time are quantized units. If you believe space and time are real, then you must conclude that we can not measure them on any magnitude less then that of the Planck scale. The alternative is to assume space-time do not exist on scales smaller then that of the Planck length/time and propose some alternative that explains what happens on such a scale.
>>16537060It is the size of the weave of physical reality >t. guy who regularly has OBE's
>>16540257>speculativeIt’s a purely theoretical issue, not an experimental one so the word “speculative” doesn’t even apply. If you need another example, QCD works the other way around and the usual techniques fail below about 200 MeV.>Schizo.No, just standard jargon in something you clearly don’t understand.
>>16537060no, it means that devices made of matter have a limit to how far they can measure
someone turn the anti-alias off
>Does planck length mean space is pixelated?No, they are just random units>>16537070>No. All it means is that there is a smallest length that can be measured.Also not. plank length is not the smallest length. Its just a small length that has been memed into being le fundamental units of the universe. Theres zero evidence for this, or any argument at all. its just a meme that people run with>>16537515>planck length is a theory only...Its not a theory, its just a set of units, length, time, mass, charge>>16540184>They indicate the point where general relativity can no longer be realized aCompletely random statement. Its just a small number, psychologically speaking. >>16540848>no, it means that devices made of matter have a limit to how far they can measureNo, its just a stupid unit.Same as planck time or planck mass are not fundamental at all. Planck mass is particularly hilarious since its obviously not fundamental, its about the mass of a visible speck of dust
>>16540259We know a lot about form, the measurement of form is called geometry.
>>16537060On scales smaller than the Planck length existing physics theories (quantum mechanics etc) will not work. That is the only definite meaning of the Planck length. There are many possibilities for what happens near the Planck length but they are hypothetical at this time. Pixelated reality is one possibility. Unfortunately we are a long way from doing Planck-scale physics experiments so the only attempts to answer these questions are almost purely theoretical - string theory etc.
>>16541141Anf what happens below planck time and plank mass?You seem OBSESSED about length. Envy much?
>>16541142Nobody knows what happens. My peepee is bigger than the Planck length luckily.
>>16541144>Nobody knows what happensReally, not even below planck mass?You seem to think the universe is just length. Forgot about the other units already?
>>16541146Whatever you like, retard.
>>16541146>You seem to think the universe is just lengthSpace is only made of lengths, the three dimensions are just orthogonal lengths, mass isn't a unit of 3d space at all, it is a unit of matter which needs some other measure besides space due to density.
>>16537060If so then that means pi = 4Which would make a lot of calculations a lot easier.
