In that direction there was an idea a few years ago about detecting if on a very small scale we can observe any grid-alignment effect. https://arxiv.org/abs/1210.1847 I think there was another paper about similar grid-alignment idea for some properties of galaxies, but I can't find it now.

> The apparatus would necessarily exist within the closed system. does being in a multiverse influences our world in any way using current theories? yes > we can eventually figure out and run an experiment no > then studying it is as productive as searching the Russel's teapot this is how you set apart a theory from speculation, a falsification test. i.e. > http://arxiv.org/abs/1210.1847

The cost of simulating entire universe becomes increasingly expensive to the point you need a universe of energy to simulate a universe. Daniel Dennet in his "Consciousness Explained" makes a good argument why this is so. Also there was some research done on the constraints on the universe as a numerical simulation http://arxiv.org/abs/1210.1847 telling us that we can do experiments to detect if we are living in a simulation (but the simulators always have a freedom to "increase the resolution" of their simulation to thwart our efforts). The paper does not discuss if there are limits on how…

http://arxiv.org/abs/1210.1847 This comment is a response to a bunch of the comments in this thread, but it didn't make sense to scatter the information throughout the page. The way lattice QCD [0] works requires a few approximations in order to fit the problem into your computer. You (1) simulate a universe with finite volume (state-of-the-art calculations have boxes just a few times bigger than a nucleus in each direction), (2) discretize the space into a bunch of points some lattice spacing apart connected by links, and, (3) possibly simulate at values of the quark masses that are not…

ArXiv paper: http://arxiv.org/abs/1210.1847 This work attempts to draw out the presence of a simulation by looking for tiny violations of known/expected symmetries, which is always worth doing. We should note, however, that an excellent simulation could exactly cover its tracks, lest the underlying architecture cause unintended artifacts. From a CS perspective, the simulation's developer might create unit tests that guarantee the preservation of symmetries. A theorist who develops an experimental test that could prove we do not live in a simulation should be lauded. There are experimentalists…
