If you enjoy this kind of speculating you might like the Expanse series of books and TV shows.

They have humans growing up on Mars, the asteroid belt, moons. Anyone who doesn’t grow up on earth cannot go there without extreme gravity training.

That series strived for realism in that regard, and in using magnetic boots to work in zero gravity; which was admirable. That made the things that were not realistic stand out even more imo. The (unfortunately named) Epstein drive, a drive that consumes very little mass under constant acceleration allows for relativistic speeds in very little time (weeks). Their ships were flying from one side of the solar system to the other in weeks, but they couldn’t make interstellar flights? Also the effects of cosmic rays and hard radiation on reproduction makes the disaffected belter population seem impossible. That’s all fine of course, just inconsistent imo.

Shohreh Aghdashloo performance was a real treat though!

		She was also in a show with Ray Liotta (Smith) that, in spite of some unevenness, sadly didn't make it through its first season.

		The Epstein drives are efficient, but not efficient enough to run for months at a time without stopping, and are thus unusable for interstellar travel. The books go into that when talking about Medina/Behemoth/Nauvoo... The whole reason it had a rotating drum was because the engines would only be active at the start and end of the journey.

		Regarding reproduction, I'm willing to write that off to advanced medical technology doing DNA repair. Most of the plot wouldn't be that different with slower space drives, so I wasn't too bothered by that either. But fwiw, it turns out it is possible to get that level of rocket performance, if ToughSF got their numbers right: https://toughsf.blogspot.com/2019/10/the-expanses-epstein-dr... It wouldn't look the same and the power level would be higher than what all of civilization uses today, but the amount of fusion fuel isn't all that remarkable. The design uses helium-3, which could be collected in large quantity from Uranus and Neptune.

I did enjoy the first season of the series, but then was turned off by some story arcs, but maybe I will give it a try again. Are the books more consistent?

Much more consistent. Books are huge, hence the need to shorten them.

But IMHO, series have done a really good job overall. Given how nearly impossible it is to simulate micro-gravity, or other advanced technology.

Also, in season three or four suddenly everybody started cursing all the time. The series just wasn't fun to watch anymore.

		I legitimately did not notice this and I cannot imagine it affecting my enjoyment of a show.
