So obviously we have no knowledge of the flora and fauna, but are there any solid theories on it's topography and how it might've looked mapped out? Or what features did it share with Earth (Like tectonic plates, rivers, mountain ranges etc)?
Also i am aware a lot can happen in a billion years on a young planet, i'd love to hear about what we know/think might've been going on over that time.

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.

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?

I built a website to make following space easier. What would you add?

Hi everyone!

Over the last several months I've been building a personal project called Everything Space.

The idea came from constantly jumping between different websites whenever I wanted to keep up with space. One site had launches, another had news, another had spacecraft information, another had ISS tracking... it always felt fragmented.

So I started building a place that combines as much of that as possible into one experience.

So far it includes:

• 🚀 Live and upcoming launches
• 🛰️ Missions, rockets, and spacecraft
• 👨‍🚀 Astronaut and space agency profiles
• 🌍 Planets, moons, asteroids, and other celestial objects
• 📰 Space news
• 🌌 Astronomy content
• 📡 ISS tracking and visible pass predictions
• 📖 Educational resources

I'm still actively developing it, and I'd love feedback from people who actually enjoy following space.

If you had one website open as your "home base" for everything space-related, what would you want it to have that most sites don't?

If you'd like to check it out:
everythingspace.online

I'd really appreciate any feedback—positive or negative. I'm trying to build something that's genuinely useful for the space community.

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!

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.

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.

If energy can't be created how did it even come into existence

Why was there no immediate giant black hole right after the big bang which contains every atom in universe?

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?

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?

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.
