The one that always fucked with me is the thought that the universe could have been created a millisecond ago with the current quantum state of everything and there's no obvious way to prove it wasn't.
Google "Boltzmann brains". Modern astrophysics currently claims that you're millions of times more likely to be a disconnected brain that spawned from the quantum ether with all your current memories than you are likely to be a real person living on Earth.
