But their is scientific consensus that you can't transfer information faster than light. Our maths for both quantum physics and Einsteinian physics have both proven its impossible. Ohh and it fundamentally breaks causation. Grandfather paradox type shit. permalink fedilink source parent hideshow 1 child comment replies: [–] Cybersteel@lemmy.world 2 points 9 months ago I've been lead to believe that it's like if the speed of causality is the north pole. You can approach it and reach the north pole but once you try to surpass the point at the north, you begin to move in the opposite direction. permalink fedilink source parent [–] peopleproblems@lemmy.world 3 points 9 months ago To simplify - c is the maximum speed at which a "cause" can be transferred. If I send a radio signal to turn on a light, and the light will only turn on in response to that signal, the signal cannot travel faster than c otherwise it would not have been able to turn on the light. permalink fedilink source parent [–] homesweethomeMrL@lemmy.world 1 point 9 months ago Depends on how much time you got innit permalink fedilink source parent [–] Kolanaki@pawb.social 0 points 9 months ago* Teleportation is instantaneous; there is 0 travel time.🤦♂️ permalink fedilink source parent
