In a recent 10-minute video, physicist Sabine Hossenfelder argues that we cannot rule out the possibility that the universe actually thinks, incredible as it may seem. In brief, the reasons why we cannot rule out this scenario are that (a) quantum physics is non-local, (b) even Einstein’s theory of general relativity is perfectly compatible with the existence of wormholes, which don’t respect locality and which could connect the universe with itself, and (c) additionally, Einstein’s theory of relativity does not rule out the existence of faster-than-light signals; all it rules out is the possibility of going from speeds below that of light to speeds above. Moreover, faster-than-light travel would not create causality paradoxes, as commonly believed. What all this adds up to is that the universe could be self-connected on a micro-scale, and that it could transmit signals much faster than we imagine, making it possibly able to think.
Here are some excerpts from Dr. Hossenfelder’s fascinating talk:
