what's really weird is that since earth was liquid at some point, anything heavier than silica sank. all the gold and uranium and tungsten and poo poo in the crust got dropped onto earth from space after the crust froze solid. which means there's probably just as much or more of all that poo poo on the moon and mars since they've been frozen over for longer, and they're frozen solid while the earth is still making new crust and subsuming old stuff this also means theres probably a ton of uranium and poo poo in the core all bein toasty and helping keep the earth gooey inside

I took an astronomy class in college as a science GE cause I didn't want to have to take like bio or chem and it was like the first half of the semester was all "Name a planet and you pass the test" And then the second part was like "What is the origin of the chain of high mountains that closely follows the equator of Saturn's moon, Iapetus?" It was absolutely hosed i never had another class that had such an extreme jump on difficulty and it was a 100 level class Anyways that's when I learned that space is gay

I hand wrote a letter to Scott Kelly ( twin brother of AZ senator Mark Kelly) thanking him for doing a presentation at my university and for writing the book Endurance. He replied back with a handwritten note and a neato patch that I’m too scared to apply to anything. I recommend his book if you have an interest in what day to day life in the ISS is like. It covers the stuff you probably see YouTube videos of, like pooping, but there’s a wealth of other things that are really cool and actually don’t make me want to go to live there. (Apparently you have permanent sinus congestion in microgravity, and only recently did the CO2 scrubbers get improved so after several days you’d slip into this brain fog and persistent minor headache). Space is cool. I went to also see the endeavor shuttle with another GBS goon at a local museum before they put it away for three years. I might be an idiot so I don’t understand a lot of things about space, but I do like the shiny NASA stuff and the planets and the stars

Fun fact: So called "shooting stars" are just the size of grains of sand, falling onto Earth from space. Every single day, about a ton of material from space falls to Earth. A ton, every day!

George H.W. oval office posted:I think life exists or has existed at some point in the universe because no way are we the only dumb ape to ever be around It seems inevitable. Single cell life on Earth began very close to the beginning of the planet. And this is after a major collision that turned the Earth into magma. Give the endless amount of exoplanets and all the same conditions and materials, how could life NOT exist elsewhere. Everywhere.

Do many people who know about the sheer size of the known universe think there isn't any kind of life about somewhere? Sure it may not be particular common but when your working with the numbers of planets in the known universe it would have to be utterly unbelievably uncommon for earth to be a fluke. But yeah, with the crazy size of the universe obviously it may not even be physically possible even with crazy future technology to ever find any signs of other life alas. Still holding out hope some distant future journey to Europa finds some micro organism there or something! Or you know lovecraftian space sea beast who enslave/eat us all! Well not us we'll likely all be long dead then, so all good either way! dr_rat fucked around with this message at 12:05 on Mar 4, 2024 |

other life seems likely—but, with neither evidence nor any developed mechanism by which to acquire it, insisting that there must be life out there is on shakier ground than insisting you’re a temporarily embarrassed millionaire because you could win the lottery any day now. at least that dude has evidence that people do in fact win the lottery

I think we'll find other life right here in our solar system, in the various ice moons. Saturn's moon Enceladus would be the best bet due to relative ease of sampling the water. Europa, another candidate, will be much more difficult. That's one of the greatest discoveries of the last 30 years by the way, and it sorta goes under the radar: There's water everywhere. Earth is dry in comparison to some of the ocean moons out there.

We'll never know until we have a second detection of life, and that detection will have to be very "clean" and methodical, as the possibility of contamination from the probe is real and has to be addressed in a variety of ways. BUT, given that single cell life on Earth started up pretty much as soon as the planet was not a fiery ball of magma, it seems highly plausible to me that life will also start up elsewhere given the right conditions. Like a chemical reaction. Now whether that life evolves into anything complex is a whole other matter, and that complex life being "smart" an entirely different matter still.

I love space and space related stuff, so excuse my enthusiasm. I'd like to share this cool mental image with you: The Oort Cloud https://en.wikipedia.org/wiki/Oort_cloud This is essentially the outer boundary of the Sun's gravitational influence. And it's a giant sphere of ice. An ice cloud. And every other similar star likely has a similar ice cloud. Maybe all stars. So, you probably have a mental image of the solar system (and thus, every solar system) as flat plane of planets in orbit around the central star, and that's accurate. But now imagine that orbital plane enclosed within a sphere of ice particles, ranging in size from super tiny to Manhattan sized, maybe bigger. And now imagine every star out there a brilliant point of light encased in a sphere of ice particles. Little glowing snowballs in the vast darkness.

We took Scam Likely Jr to the planetarium and wouldn't you know it, we bumped into Matt O'dowd (who hosts PBS Spacetime on YT) This clearly means that Scam Likely Jr is destined to grow up to be an astrophysicist. Just as soon as they learn to crawl, then we can work on solving the mysteries of dark matter and string theory.
