A minor correction around 5:00: because the bottom surface of the fiber board is slightly lower, it actually experiences a slightly higher pressure, so there is a slight net force (upwards). If you work out how much this force is, it turns out to be buoyancy.

Also, I know it sounds dumb but why EXACTLY does it take so much more energy to say move something vertically into space versus diagonally through air. Is it purely just the work required to fight against the vector of gravity for such a long distance? The obvious example I mean is a rocket; as I’ve already been told before, that the biggest thing a rocket fights against is air resistance. But then how efficient would it be if something can be sent straight up if it’s only meeting air resistance equivalent to the mass of that much water… Maybe Cody should just start a literal rocket science series for us.

@SepticFuddy

5 ай бұрын

@@oreodog My quick stab is that the air resistance is such a problem because the rocket needs to exit quickly. Think of it like moving through water quickly vs. slowly; resistance increases drastically with speed. It needs to exit quickly because gravitational force is persistent (as opposed to air resistance which is in response to motion), therefore the longer it takes to overcome that force, the more energy will be required to overcome it. Since gravitational force decreases with distance/altitude (modeled by the inverse square law), the faster you get further, the less overall energy is required. Since that energy is stored in a massive amount of weight (rocket fuel & associated boosters), more required energy consumption means more weight, which means more required energy again to generate lift for that weight, as a sort of vicious cycle that eventually makes escape impossible below some particular speed/time/acceleration threshold.

This has the same energy as when I think about the fact that the moon and planets and stars are just objects out there. That's why you can see them, is because they're _right there._ I look at Jupiter through a telescope and think it looks pretty, and it's hard to really comprehend that the reason I can see it is because it's _right there._ Just like my neighbor's house, only a bit farther away, and unfathomably big. And the same is true of stars-I can point at Albireo and say "look how pretty that is" because they're _right there, right where I'm pointing._ And they're so far away that I'll have lived and died and been dead for hundreds of years before a photon bouncing off of my pointing finger ever reaches them, and they're so big and bright that I can still see them despite that. And it's crazy to think that those photons will have to go through more matter within 100 miles of me than the entire rest of their journey to Albireo combined

I understand completely. This thought leads me in so many different directions. Gravity and the laws of motion, and the history of collisions between objects, are all such that the Moon exists - a rock big enough to be its own world. A world which could collide with ours, but due to luck, hasn't so far. The moon is orbiting so close that we can see its surface features and the only thing fundamentally stopping us from travelling and staying there is not mathematics, physics, or chemistry, but economy and common sense. Our lives are so stable and serious, and we care about who's next to wear the big politician hat, and we have soap operas. However, all the time there's just a bloody giant rock spinning around us in a circle, and because of work and distractions, barely anyone stops and meditates about the implications for very long. It's the same vibe as looking at the sun briefly, and appreciating that the reason you can't look for longer is because you're literally looking at nuclear fission.

As I've posted elsewhere before- The greatest problem with closed ecologies is the inevitable amputation of the atmosphere. In the open on Earth, a square meter of good farmland extends at least 30 cm into the surface and has a mass close to a ton, with perhaps 10 to 50 kg of water available. But the air on top of it outweighs everything else at ten tons. Putting a dome generously ten meters above the soil leaves at most twelve *kilograms* of air, nowhere near enough to buffer the daily flows of water, water vapor, CO2, and oxygen that must flow in and out of the soil and plants. All the ills of ECLSS stem from this desperately limited air supply. For example, those ten cubic meters of air, at 400 ppm CO2, contain a whopping seven grams of CO2. The enclosed ecosystem is balanced on a knife edge. Any off-earth closed ecosystem will need a good buffer for oxygen, CO2, and nitrogen. All three gases must be able to be drawn from and returned to storage as the biosystems fluctuate in throughput due to seasonal and (on Mars) weather changes.
