>10^26 planets in the universe
>Out of planets and moons in our solar system, we see water on 5+ of them
I'm thinking alien life is kinda probable

>Black holes and the universe contain/contained a singularity
No. Singularities are purely hypothetical predictions and current theories break down when dealing with them, implying that singularities are a nonsensical thing. They are an extreme extrapolation of relativity and relativity is dogshit for micro scales with many errors there.

>Virtual particles pop in and out and annihilate each other in a flash of light
No. Virtual particles are a model for certain small forces active in a vacuum. There are no actual particles from nothing and no flash of light from their annihilation.

>Hawking radiation
Virtual particles are a math model and not something real, so anti-particles do not get sucked up by black holes to lessen their mass. The real explanation is something else and this was just a popsci myth.

>Quantum mechanics are some sort of true randomness
No. Due to the small scale of QM, measurements are probabilistic due to tool interference on this minimal scale and the extreme chaos making it impossible to have all data for such a small system. Every single interaction in QM is deterministic. It's a measuring problem, not some sort of universal randomness. And the wave function is again a statistical approximiation for an extremely complex system that is too complex for us to model currently.
