### Re: Science-based what-if questions

I mean, if it has infinite density and finite, nonzero volume, then by definition it has infinite mass.

### Re: Science-based what-if questions

Also, if that thing have finite mass, then technically it would be made out of infinite of infitestimal with force infinitely close to zero.

Edit: Singularity here is more like in a math sense than a physics one. Weird point of math, is what I'm saying here, it you get my drift

I'm not sure what you mean. The idea of continuous matter is that a pure element is made of nothing but itself and is the same at all scales. (The latter point is the real problem, incidentally.) I don't know which force you're involving here.

Why would there be a singularity?

### Re: Science-based what-if questions

I think the 'singularity' would be in the first-or-more order derivative of 'thingness'. A hard edge of 'whatever' (say a "solidity field", as I had originally envisaged it) would mean an infinite slope/point of inflection from "nothing" to "something". Or so I interpret AK's "singularity in a mathematical sense". Or else closely related to the "AI singularity" (which is really the Event Horizon, as I think I've suggested at another time in another thread!) in that it's a boundary between universe-as-we-know-it and Here Be Dragon (i.e. as a Mass Noun/continuum).

Sorry, I kinda talk wrong here. What I mean is, if the thing is finite, yet could scale infinitely smaller without finding gap, then if you split this thing into infinite little piece, each piece would be the same object infintitely smaller, with infinitely less thing going on for it as any scale (less force, less mass, etc...)

### Re: Science-based what-if questions

If we step away from infinity, the point is that at any given scale, all extensive properties will be scaled similarly, so there will be no qualitative difference. In such a universe, there would be no particular reason the Earth should be 12,700 km in diameter rather than 12,000,000 km or 12 km or 10

^{-100}km.### Who is online
