Can you imagine if one zipped by our solar system, completely disrupting/scrambling our orbit?

What is space expanding into?

Wouldn’t that area already be space, just empty?

I really don’t understand this stuff.

I thought about quantum right after I posted that dammit . Reading the Einstein biography by Walter Isaacson right now and you can’t tell me that guy wasn’t high on some good stuff

Isn’t stars being stationary the basis of celestial navigation?


Sure they are moving. They only look stationary for the two minutes a person is looking through a sextant to measure them.

(In reality, the Naval Observatory has to update the books defining where the star is going to be every three years due to minor changes in stellar positions.)

I thought science told us stars didn’t move? I guess we don’t know as much as we thought


What?

Mine was about time travel, I used a theorem regarding integration of a closed loop in the complex plain to support the idea that you can't go back in time.


We used to drop acid and play Starfox or watch MTV. You're way to productive.

And to make it even more complicated than that, consider that spacetime is not a fundamental property. It's an emergent property of quantum physics.
