Or how strong would the gravity need to be, before we were basically locked out of space travel?

Is there a mechanic of the cosmos behind this? Is it a coincidence? Or is there something about smaller celestial bodies that might make it easier to assume we're looking at water? It seems really convenient for Murphy's Law that this caveat just happens to come up any time there's a place with water, which I ask about after discussing with someone just how absolutely small Ceres is.

Idk if this has been touched on before. But today and this past week for some reason this has been in my head.

How did space come to exist.

Forget the big bang. How did the first ever THING appear ever. Before the mere consciousness or idea of space even being a thing prior to the big bang.

I’m talking the first ANYTHING.

With the plans to build on the moon to get prepared for mars.
Are they not worried about asteroids, debris or other things from landing where the astronauts might be trying to locate. Is the South Pole less common for it ? I know there isn’t a close planet like earth for them to “develop “

Or is it just not likely to happen. I understand things could happen on earth to with asteroids but with the atmosphere and moon being there it hasn’t been a issue

So this might be a dumb question
But when they are looking other planets and find other elements. And go. There might have been life on this planet or there is life

Wouldn’t that be based on our life. Like wouldn’t other planets have different types of life forms. And elements making them up

I want to apologize because I will ask some dumb questions but I love space and I love weed and sometimes when I’m high the two collide. Bro is gonna bru sometimes.

To be specific heat from the sun directly heats planets that heat travels from the sun to a planet. The vacuum of space is the coldest part of the universe so why don’t solar rays basically freeze out when traveling the distance between the sun and the planet? Since space is a vacuum there should be no way for heat to travel ?
I’m sorry if I used the wrong flair tag

Why not a Rat or a Cockroach? They are a nuisance and they have the ability to survive harsh conditions.

my topic is space med and longevity and i want to have interactive activities. please give me ideas and not trivia plss!!

Possibly a silly question, but if aliens were to exist in some faraway galaxy 80 million light years away, and magically know to look at earth with some big massive super powerful telescope or whatever similar technology they have , would they see earth as it was 80 million years ago? Like with dinosaurs and stuff instead of anything modern? Does that technically make us , to an extent , invisible to any potential life out there?

Assuming you can mix/match from any of the shuttle launches to make the best possible crew.

During ascent, STS-27 (Atlantis) sustained significant damage to its heat shield.

From my understanding the ascent damage on STS-27 (two flights after the Challenger Accident) was underestimated due to the encrypted nature of the mission.

Upon reentry and landing, the damage was discovered to be far more extensive than originally believed. A very similar situation to the incident that ended up destroying Columbia.

In the Columbia Accident Investigation Board, an audacious plan was presented that may have been committed to save Columbia (if her ascent damage had been properly investigated).

What would have been plan to save Atlantis on STS-27, if her ascent damage had been determined to significant for reentry?

When we sent out Voyager 1 (later Voyager 2) into space, we sent golden records with with them to let any living things that might find them so they would know where to look for us. What I am thinking about is "What if we send living samples into space like we did with Voyagers so nothing will stop them" I mean things like self sustaining tarrarium. IT only needs gravity (could be done with centrifuge), light (could be done with LED grow lights) and tempeture (this could be some heater), but I am still thinking about the power ( maybe some power from solar panels but after some distance it would not be enough. What do you think of all this?
