Here's a cheat sheet to humanity in space: TL;DR: It's real hard Otherwise, there's no where good to go Humanity's only future in space is in spinning space stations There's very little appealing about Mars Or the Moon

Cool thing to consider: There's the visible universe, which is the measure of the furthest source of light. However, because of the expansion of the universe, there are parts of the universe from which light will never reach us - it's too far away, and with space expanding, always further and further..... We know nothing about this unobservable universe. Like how big it might be. One can assume the laws of physics are the same, but just an assumption. And we'll never know otherwise.

Speaking of smashing rocks, we live on at least Earth 2.0, as Earth 1.0 was mostly destroyed in the collision with another small planet. Which we mostly absorbed, leading to our big iron core, and our relatively huge Moon. Earth 2.0 was a much improved planet.

bradzilla posted:there were thousands of planets in the proto solar system. they smashed into each other until the elite survivors remained and aligned into the perfect delicate system of equilibrium and orbit Indeed. I think what's different here (with the collision that ultimately produced the Moon) was it was pretty late in that process of building.

We have iron in our blood. Blood being super important to our success as a machine. That iron came from a big old rear end star that exploded, long ago. And not our Sun, that's our brother/sister/uncle/aunt. But rather, some long gone big rear end star, that exploded, and seeded the gas cloud that became our Sun and solar system. The iron in our blood is older than the Sun, older than the Earth....

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.

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.

Mister Speaker posted:A buddy of mine is in Puerto Vallarta or something and the other night he posted some video he said was of a comet. It certainly looked like a comet, it had the coma tail but it moved across the sky in seconds. I was under the impression comets didn't transit thus quickly, and tended to hang around in the sky for hours or days or even weeks at a time, but when I pointed this out someone smugly shared some tracking website that seemed to indicate the opposite. Comets don't enter Earth's orbit.

Mister Speaker posted:I believe this, but it did look different from any meteor I've ever seen. Like I said it did have the coma tail and didn't seem to streak like ones I've seen. I wonder if i tell at this guy 'it's a meteor, not a comet' he'll fire back with some 'same thing Meteors in the atmosphere can have flaming tails, but they are fundamentally different "tails" than comets - one is burning up in the atmosphere, the other is being outgassed by solar pressures. Fireballs I think they're called, and they're just bigger meteors with more mass and a chemical composition more prone to "burning".

I'm gonna go on here about gravity points. It's something I think about all the time. To wit, we live in Space-Time, a 4 Dimensional fabric that is shaped by gravity. Gravity is created by mass. Everything with mass shapes this space. You have mass, as does the Earth and Sun and Milky Way. Mass changes, as everything changes, including Space-Time. Thus, we live in a 4 Dimensional cube of Space-Time in constant modulation based on mass. Now, that's the big picture - planet, star, collection of stars, super massive black hole, galactic cluster, we go on and on in gravitationally shaped space. Forever. So, that understood, you can understand yourself as 4 geographic reference points.... with some flair.
