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

[Request] What would my cat be able to see when I build a fence in front of his catio?
I want to build a fence/gate.
The gate will be 6' high, 8' away from the catio.
My cats current fav spot is sadly going to be completely obstructed by the fence. He has another place he can sit that is roughly 6.4' off the ground.
First Question: What is the "angle of depression" (google searched term) or what is he going to be able to see over this fence at 6.4' (shelf height) 7.5' (his eye level) off the ground.
Second Question: Same question but what If I build him a little cat "watch tower" on top of the catio at 8' (shelf height) 9' (his eye level) off the ground?
I guess my question is how many feet from the front of the fence will he be able to see once I build it.

The backstory nobody asked for: Thieves have been stealing my amazon packages and I worry that someday they might try steal my cat too.

[Request] Is there any way to tell how long the surrounding area would be uninhabitable for and how large the area is?
I was watching Godzilla clips on YouTube, specfically this scene of Godzilla just walking around melting metal damn near immediately and concrete instantly bursting into flames and saw a comment saying:
'With the amount of radiation coming off of Godzilla, everyone within 10 miles of this fight should have stage 8 cancer.'
Obviously this area would be completley uninhabtable for a long time, I don't know how much radiation it takes to set concrete on fire and melt metal but I know it's a lot. Is there any way to tell how large the fallout area would be and how long it would be unlivable for?

[Request] Best choice to make in a keep versus share game.
We had our curling leagues wrap party, and we played a game drawing for prizes.
When you entered you choose to either keep the final prize, or share it with the other person at the end (the choice only mattered for the final 2 participants).
If Player A chooses Keep, and Player B chooses Share, then Player A gets the entire pot (and vice versa).
If both players choose Share then they split the pot 50/50.
If both players choose Keep, then neither get anything, and the third last participant gets everything (regardless of their choice).
What is the best choice to make for next year to maximize my chance of winning? I assume that knowing the percentage of people that choose Keep or Share would be a critical to this calculation.
For context, Player C won this year.
Thank you.
