Inversely so.
You can have a sphere with a radius of 1 meter and a density of 100 moles... or 200 moles.
You can also have a sphere of 100 moles that has a 10-meter radius... or a 10-centimeter radius.

2/10 Good idea, but too obvious.

Anyways, distance only involves 1 dimension, while density needs 3, so there is no way manipulating them can be similar.

>> No.3812108

But multiple manipulations of distance can be sort of like manipulating density, can it not?

There's also weird stuff like using density manipulation to gather people together.

How the heck would you manipulate distance? There is no way to change the distance from a point A to another point B. Unless you were to bend the plane to bring the points closer together in the vein of L'Engle's tesseract.
Disregarding this, manipulation of density is more than just distance. As we know, ρ = m/V, so you can manipulate mass as well as distance over 3 axes.

Fun fact: Galactic red-shift is caused mainly by the fact that the space between galaxies is growing and not because of their relative motion.

That means, if we took two objects which are motionless in respect to each other an we set them apart at a big enough distance from each other, the that distance between them would still grow. The energy density of this system would decrease over time despite the lack of motion.

Cosmology is fun.

tl;dr No, manipulating distance and density can mean the same thing.

>> No.3812307

>>3812289
He already mentioned that manipulation of distance can also be manipulation of density, though. He was just saying that manipulation of density is not always equivalent to manipulation of distance.

Or that's what I got out of it, anyway.

>> No.3812323

>>3812289
I thought that was just because of momentum gained during the big bang. If you magically put two objects stationary relative to each other in space outside the influence of any electromagnetic or gravitational fields, why would the distance between them grow?

We don't know why, it just does. Astronomers found out that doppler shift alone doesn't explain the amount of red-shift in observed galaxies (in relation to their observed velocities). Lookup the Hubble constant on Wikipedia if you're interested in finding out more.

>> No.3812351

>>3812323
We used to think it was because of the big bang, but further research seems to show that the expansion is getting faster as time passes. There's debate as to exactly what's causing this and if it might just be a mistake we're making because of something we don't quite understand, however.

I think.

That may very well be the case. I've only attended some cosmology lectures last year. If it's any indication, the professor conducting those lectures didn't know either and he was as up-to-date in cosmology as you could get.

If it isn't well-known enough for us to know (or find out quickly through the wonders of the Internet), it hasn't been peer reviewed enough to be considered confirmed, so if anyone has the answer it's still effectively conjecture at this point.

That's exactly what Komachi does.

She mainly does it to lengthen or shorten the length of the Sanzu river depending on how many people will miss them.

Suika doesn't really manipulate density as a physical phenomenon, she has the power to gather or disperse things and density-fuckery is just one of the applications. The whole premise of IaMP is that Suika starts a party by "gathering" people.
