thanks.

i meant, what did the comment say? it had 105 upvotes

hey, not everybody likes it in 40°C heat. maybe she just had superior air conditioning.

technically, we’re all just a small bean in this big world.

eh, mobile connectivity is good enough for me lol

grippy socks jail is where i will one day meet my future wife, i can feel it

are you insinoating it doesn’t exist?

nooooooooo. what did it say?

3 days without shitposts you say? couldn’t be me

fun fact: we could accelerate a huge spaceship to approximately 3% speed of light with technology that we have today.

nuclear fission + ion drive would do that.

at this speed, traversing the entire galaxy (Milky Way) once would only take about ~5 million years, or about 1/1000 of the time that life has existed on Earth.

That’s why it’s called analysis

hate makes people feel strong, so people love to hate on stuff.

did you know: plastic is a glass, and so is butter.

batteries haven’t been built in the past because they weren’t needed, but they’re being built today (look up sodium-ion batteries) and they’re cheap and effective.

btw the reason why denmark and germany are building so many wind turbines is mostly because they’re so far north.

see my other reply in this thread

basically it doesn’t move the moon closer, but it makes the Earth rotate slower. that’s where the energy comes from.

basically the tides transfer angular momentum from the Earth to the moon.

actually, the moon gains angular momentum from the tidal movement that it causes, and that’s what makes it move further away. the reason is that it takes Earth about 1 day to rotate once around its axis, but it takes the moon 28 days to rotate once around Earth’s axis. so Earth has a higher angular velocity, and the tidal movement tries to reduce that difference to make the two tidally locked eventually. ironically, this process transfers angular momentum to the moon (to speed it up), which makes it move further away and thus the angular velocity actually decreases. yeah, orbital mechanics is weird.

(btw this is not a joke. it’s really that way, difficult to comprehend i know).

btw geothermal does not come from the earth’s rotation. it mostly comes from nuclear decay of heavy isotopes in the earth’s interior and the enormous heat capacity of the earth’s interior, which means it’s still warm from the friction heat from when the planet first formed. in other words it’s there since the Earth formed, independent of the sun.

also there’s another (practically accessible) form of energy that comes neither from geothermal nor from the sun: you can pull energy out of the tidal movement that comes from the moon’s changing gravity field as it orbits around our planet. i think that one’s not really being used though because the only way to really utilize it is to build dams across havens and important shipping routes and that interferes with trade, which is considered the more economically valuable activity from the two.

well actually there’s renewable energy on the cosmological scale (look up E. Harris - Mining Energy In An Expanding Universe), at least theoretically. nobody’s ever practically utilized it (afaik).

they’re more economically efficient than nuclear, which means they give you more bang for the buck
