Is time fundamentally different from space? "With respect to the brain scan: this way of visualisation is chosen for simplicity" -- I know, but that is besides the point for this question. :) I picked that image because it illustartes how 2D scans in rapid succession look like a substance that evolves over time. |

Is time fundamentally different from space? "you can in principle move freely forward and backward, while in time, your motion is fixed" -- But is that a characteristic of the dimension, or a limitation of our technology and/ or dimensional nature? Afaik, there's no evidence that time travel in the past is impossible, so there's nothing that can be said for certain about that for now. |

What are some scenarios where FTL information transfer would violate causality? @JustinL. A way you could think about this is perceiving a 2D plane (a paper) from different angles in 3D; if 'all is right', your perception will distort, but you'll never see an impossible shape. The same way with perceiving a 3D body in 4D; depending on how you move in 4D, your perception of the 3D body might change, but you shouldn't ever see something that is impossible. |
