No, it's talking about optical resolution. If you were to make an image of the universe surrounding our Solar System and galaxy, there's a maximum number of pixels that you could zoom in and see before everything gets fuzzy due to spacetime warping the path of the photons as they made progress through the universe. (Like taking a photo through frosted glass, except the frosting is much finer here.)
- Ono-Sendai 11y agoIt is talking about planck-scale stuff though. And the effect is pure conjecture.
- fennecfoxen 11y agoYeah, if you mean it that way then the conjectured phenomenon providing the fuzzing seems to be basically at-or-around Plank-scale stuff which arises from having the Heisenberg uncertainty principle around (because there's a hard boundary on the precision with which a process could demonstrate that space is empty, so in practice, it's not strictly empty, just a close approximation that's can have quantum fluctuations).
