comment Is the Earth going to evolve towards Mars' fate or Venus' fate?
I'm not sure what you mean by lose the moon, but I'm going to assume you mean it leaves the Earth's orbit. This is unlikely, as a result of the tidal locking you mention (see here). I'm not sure what effect the Moon has on geological activity; plate tectonics are primarily cause by the earth's contraction and convection current's in the mantle, heated by radioactive processes in the Earth's core. I think the ocean's sublimation of CO_$_2$ has a greater effect on atmospheric conditions, I'll update my answer.

comment What's the bleeding-edge model for how Population III stars are born and evolve?
@Aabaakawad I'm looking for a more comprehensive review, rather than the few specific questions found on SE

comment Can we conclude with reasonable certainty that there is/are no Type 3 Civilizations in our galaxy?
"We'll need even more international cooperation to get a bit further out for longer durations of time - and that requires international diplomacy and cooperation" - as wonderful as this sounds, I don't think it's necessary. Space X is putting things in orbit with corporate resources, and the bar to entry is getting still lower. Automation and advances in robotics could enable large industrial projects to be carried out by a few people. There's also the scientific and engineering acceleration effect from warfare; it's amazing what a country can achieve when faced with an existential crisis.

revised The big bang and our expanding universe
removed reference to stars in expansion explanation, as stars are very dynamic relative to each other within galaxies. Could cause further confusion for the OP if they think that stars in galaxies are static

comment Are there good animations of the movement of proximate stars over long time periods?
@HDE226868 you should post that as an answer, the question asked for a visualisation, not specifically an animation
