Theories:
Quantum Solipsism: The universe revolves around you, but you're just a tiny, insignificant speck in a vast, uncaring expanse.
Multiverse Theory: You're not just living in one reality, but all of them, simultaneously. But which one is real, and which ones are just simulations?
Meaning is just a number: Everything is just a series of 1s and 0s, and meaning is just a fancy algorithm.
We're all actually holograms: The universe is just a giant computer simulation, and we're just pixels in a vast, virtual reality.
Paradoxical Soup: Time is just a bowl of steaming hot soup, and the past, present, and future are all just flavors in a never-ending broth.
