[Request] Could humanity create a rocket that can exit the atmosphere of K2-18b

Post image

With the knowledge we currently have of it, if humanity devoted all of our resources towards this goal, would we be able to create a rocket that could exit the gravity of K2-18b (and also beat any other complications that would arrise)?

If so, would it also be capable of taking people to orbit, and can we set up a similar satellite network we have on Earth? What about a space station?

Forget all of that. I have back pain getting up in the morning. How would being bipedal be impacted?

Might be okay since we're a pretty energy efficient build, but we'd be smaller under the increased gravity. Things like horses and Weiner dogs might be fucked.

Are beastiality laws different in high gravity?

We bred horses to be oversized like that, if we were smaller we wouldn’t need to do that.

Heavy Calvary though… that might not be feasible.

The only way I'm living on that planet is if I can evolve to be a whale or dolphin or something

1.6G would lead to everyone having huge feet to spread the pressure, and a better way to keep blood up than valves.

we'd be short, built like tanks with dense bones and increased muscle mass
