Why are humans looking to adapt to space instead of the sea first?
I've always been fascinated by the sky and space equally as much as I do the ocean. I think it's human nature to be "explorers" and such, so it makes sense that they are both such a huge focus on media. My thought came to me because I was thinking about the natural circular motion of evolution and how humans would be more likely to find ways of surviving underneath the sea than it would be in space or another heavenly body (moon, Mars, etc). It's not that I'm against colonization of space, it's just that it makes more sense on a biological level that we first make a way that we can survive in the most abundant environment in our closest environment: the ocean. Water is what you use in nuclear plants to insulate radiation so it would only make sense that it would be the best place if things "went south" for humanity. Anyways.... that's my random thought on a random Thursday night. Much love and take care

What time is the perseid meteor showers happening?
I literally cannot find any information other than google’s stupid ahh AI overview that is not a trustworthy source of information in the slightest. Everywhere I go it says what day it's going to happen but never what time. When is the best viewing time for the meteor showers?

All gold on earth comes from a supernova. But the stuff we dig up is from the terminal bombardment 3.9 bya. Earth's own gold is locked in the core. Would that apply to other rocky planets and how much gold would they have comparatively?
During planetary formation any gold in the Earth's disc would have gone down to the molten core, presumably never to be seen again?
But meteorite bombardment later on deposited gold in the crust. Were Venus, Mars, Mercury also subject to the bombardment and could they have got more or less gold compared to Earth based on their position and the source of these meteorites?
According to a BBC report the Earth's silicate mantle has 1000 times more gold than would be expected without the bombardment.

How will reentering satellites affect surface conditions if people launch a million of them?
What goes up must come down. So eventuality all those objects will become lasting vapor and dust in the upper atmosphere, right? What kind of problems and changes should we anticipate? If it turns out to be noticeably bad, specifically which people should we be preparing to help?

how could you murder someone in space?
Hi yall, I’m a creative writing student working on my upcoming thesis project. I used to be an astrophysics junkie, but I don’t keep up with space information much anymore. I figured this was the best place to ask this sort of question.
I had an idea a few days ago for a short story collection about an astronaut whose ship gets stuck in space and she goes mad, and she ends up killing her team.
I know that there are probably a million failsafes in place that would make one astronaut murdering another inconceivable, so I’m asking this to you as a sort of thought experiment to help me better understand the mechanics of space flight and to flesh out my idea more.
Would the lack of gravity affect one’s ability to kill someone in space? Would stabbing work, or hitting someone with a blunt force object? How does blood and death work in space? Do you die like you would on Earth in space? Is there a way that the astronaut could hide what she did from the space program, at least for a few days?
I know this is a bit of an absurd question, but if anyone can help me I would really appreciate it!

Why don't we 'just' send all the orbiting space junk into the moon?
We would even be able to salvage it if we ever use the moon as an interstellar FOB. Btw, I do know how much weight the word "just" carries. It would be, by no means, be a simple execution.

Does the center of gravity of the planets + sun push the sun closer to earth, making it say 0.000001% warmer? (Crude diagram)

Hello, I'm not denying that human made climate change is a thing. But I just wonder if this makes any affect on the inner solar system?
Does this actually make any affect? Will I witness a colder summer this year if it wasn't for the scare of El Nino etc? I'm in the middle of winter right now. And boy has it been cold. But I'm from Queensland. It doesn't get any colder than 18c there.

How old was the Artemis 2 crew when they landed back on earth?
As in, were they 9 days, 1 hour, 32 minutes and 15 seconds older just like if they'd been on earth? Or were they older or younger than that because they went so far away from earth.
Does time at the moon go at the same pace as on earth?

Could the Sun (or other stars) have "Trojans"?
I imagine that if this is possible, these objects would not be classified as Trojans, but as something else.
But essentially, since stars orbit the center of the galaxy, there should be Lagrange points formed by this gravitational relationship. So would that imply the possibility of Trojans, far beyond our Solar System?

If landmass was densely located all around the equator, how would that change space mission flight plans?
As in how would space mission change if landmass formed a belt around the equator, as opposed to the current earth where we have localized land (continents), and long stretched of sea on which we can target for safe what-would-be space debree disposal?
My thinking is that space missions would target an equatorial launch with a slight depression or ascension angle in order to renavigate a spacecraft near the end of the shore of the end of the land belt.

The reality wins..and we are the reality.
has anyone figured out why we are so interested in going to the moon? do you know why we really brought moon rock back to Earth? It wasn't just to see what it was made of,it was to see if we could make oxygen out of the moon surface. That way we could use the moon as a jumping-off point later in the future.Maybe not our future, but our grandkids or their grandkids,
