Robot controling pouring process from a bottle it is a very complex problem involving turbulence, unless you can make the robot to start pouring slow enough at the beginning (but it might not help). My suggestion, is unless your thesis requires to use fluid mechanics, use some easier algorithm based of feedback instead, it will be simpler and closer to what a human do. |

Paradox with Gauss' law when space is uniformly charged everywhere I agree with you that it is "physically" impossible, or at least dependent on the physical process. But mathematically, you do not need to build anything, it reduces to a mathematical problem: give a space, a metric, some second order equations, and the problem should be either well defined or not. Apparently Newton's law does not define a well posed mathematical problem for the case of homogeneous density and infinite space. |

Is Newtonian gravity consistent with an infinite universe? @Chris thanks for the attempt, I'll answer my doubts below your answer. |

What happens at the interface between two universes with opposite thermodynamic arrows of time? assume the two universes are disconnected for most of their history, and become connected at some point in the middle for a finite amount of time (trough a wormhole?). It doesn't matter if you name it a single universe or two, what matters is that the thermodynamic arrow of time is in the opposite direction between them, at least when they are not connected |

Is Newtonian gravity consistent with an infinite universe? The best I could bet from the redirected question is this quote: "However, the mass can't be negative and the energy density is positive. This would force a violation of the translational symmetry in a uniform Newtonian Universe". It still doesn't give a satisfactory answer. For instance: how is that symmetry broken if we assume that there is no noise nor small density fluctuations in the system? How can you choose then the absolute "origin" that will break the symmetry? Still doesn't make sense to me. |
