And the fun scientific counterpart of the Boltzmann brain. The idea that in an infinite universe (at least in a couple of the spatial dimensions if not also a time dimension) random fluctuations could combine to form your brain. Including all of your memories, thoughts, hopes and dreams. You think you have had an entire life, but in reality your brain was just formed moments ago. And it may possibly stop existing in a few more moments, this moment being the only one the brain has actually experienced.
When taken to its natural conclusion, the entire Earth of even the solar system or galaxy might have just been created by random chance. The perfect storm of randomness. It may have been created longer ago or just nanoseconds before now. There is no way of telling.
Thermodynamics has been used to counter and strengthen this idea. And with infinity on the table anything goes.
I always found the idea of stable Boltzmann brains fascinating. The idea that on an infinite enough universe, there must exist self-sustaining minds that function on an entirely circumstantial set of rules and logic based on whatever the quantum soup spit up.
A moment in which I sit on the toilet and read philosophy on my fondleslab and perhaps make this comment. Really a wild thought
