Like how terrible a wound is in space. I never thought about bleeding in space. Figured you would bleed less, and it would be easier. Scott is right about how much space we waste in our homes. We must fix this to stop being wasteful. I demand all houses to be 7 foot ceilings unless you are over 7 foot! Same height, but instead of two floors, and an attic? Seven floors! That would be a crazy house. If I were filthy rich I would build it then rent it out for super cheap. Break even basically! Then if it succeeds I would buy a ton of highly sought after houses, and build these monstrosities as three people homes. Call it the rat house.

I always imagine the first relativistic space travelers, finally arriving at a habitable world, only to find hyperspace travelers from later generations have already come and gone with all the resources.

Well, consider that it's one of the most critical systems on a ship, along with inertial dampening and probably more critical than life support and you'll see why it rarely fails. There are several episodes of ST where gravity fails temporarily or a dead ship has no gravity requiring the crew to use "gravity" boots. Generally though you ignore it unless you need it as a plot device. I think it's more amusing that the vast majority of planets they visit have a gravitational force similar to earth.

By far the most frustrating thing about Gravity is how incredibly weak it is: Results from gravitational experiments we attempt in labs are ridiculously difficult to measure, and the only other option is looking up into space and hoping something happens that tests whatever it is we're studying; It's practically impossible to include gravity in any Quantum theories since it's effects don't even register at that scale; And even if we somehow figured out a perfect theory of Gravity that works seamlessly with the Standard Model and we discovered some way of controlling it, we would still only be able to generate tiny effects unless we were willing to make planet sized machines.

Mindless unguided process can't magically code information based life. There is no physical process or natural phenomenon that can create such communicative information. It's an immaterial concept to start with information. Rationality does not come from irrationality, the burden of proof is on those who say it does the naturalist. Natural selection is variation allowed within the genome. It's not a mechanism for evolution, it can't create anything. Turning genes on and off and swapping them isn't creating the genes to start with. No new information is being created. Entropy and information theory all point towards information decaying over time not the reverse. The statistical probability and logistics alone make evolutionary theory patently absurd. Whole thing is ridiculous to even entertain. It's all predicated on a mechanism that does not exist and logically can not exist.

Artificial gravity produced by rotation would certainly be different. I think people would be able to adapt fairly well at least in the short term. Years ago my wife and I took a train ride in Canada. The tracks weren't very smooth and the train accelerated randomly in various directions. None of us passengers could walk without holding on to something. Yet in the dining car the waitress was fully adapted she walked easily carrying trays of food. Then unbelievably poured coffee without spilling any. Although artificial gravity would be different . I doubt it would be as difficult as the random movements of that train.

It produces an artificial gravity well because it reacts like mass. At the moment its effects aren't very controllable. Not to mention it takes 10 GW in to get 3GW out. Until it makes more energy than it takes to produce it isn't commercially viable.

2001: A Space Odyssey was such a masterpiece and Kubrick's SFX team did an amazing job of helping to make it fully believable that rotation was so plainly the way to create artificial gravity. There was a flaw, though... the moon. Everyone moved about the Clavius base like there was 1G gravity. Anyway, the one thing that made the most sense was suspended animation. Wake the crew up for short periods of doing work, then put them back in hibernation. Of course, assuming it's a perfect kind of hibernation where no bone or muscle mass is lost...

You have made a mistake: If you flip your direction when using Orion drive you are not flying into your nuclear explosions. You can get some "wind" of your previous (before you flipped) explosions, but they should dissipate very well in a day or two. So you can completely avoid contamination from the flip. Because there is no stationary atmosphere in space (or at least: practically), firing your Orion drive opposite of the direction of your velocity does not result in flying into nuclear explosions at all. Things are quite a bit different if you are travelling at relativistic speeds.

Accelerating with 1G constantly or reaching very high speeds in space has one essentiell problem: crashes!

Lying down while sleeping nearly eliminates negative coriolis effects meaning a much smaller radius on the order of a few tens of meters, if that, would be sufficient to provide intermittent exposure, which would be better than none at all. There is some work being done along these lines. We should not allow a demand for the perfect to eliminate the good enough.

Litres. Liters are what you lit 🔥 at the start of your video. Love from Melbourne, Australia.

In 2006 the ESA did an experiment proving you could create gravitomagnetic fields to warp space time by rotating superconductors at high speeds, prior to that it was shown in two separate experiments in the 90s, one by a Chinese-American named Dr. Ning-Li researcher at the Center for Space Plasma and Aeronomic Research and Eugene Podkletnov at the D. Mendeleev University of Chemical Technology of Russia in Moscow.

When you listed the issues with "weightlessness" I think you missed one of the biggest problems: Reproduction. While no space agency has done rigorous experimentation on it, small scale tests have failed to get a successful incubation of any vertebrate. Some invertebrates have been hatched, but Mice and Frogs fail to develop embryos, and it seems very likely humans simply wouldn't be able to get pregnant without gravity; which kinda puts a kibosh on long term colonization of space without being able to replicate gravity.

@michaelnewton1754

Interesting... I wonder why, and how much gravity would be needed. I always figured the tethered ships in formation would be the way to go. You could extend the tether enough that the rotations could be slow, and the difference between pull at head and feet would be minimal. Then maybe have some sort of 'climber' unit attached to the tether, to transport people and items between the ships.

@@michaelnewton1754 My guess is that there are many points in orientation and migration of cells during embryo development that uses gravity as a guide. I'd wager that it doesn't take much gravity to get embryo development of vertebrates, but micro gravity (which is pretty much none) just won't work. Like I said this hasn't been thoroughly tested, but NASA has failed to get fertilized frog eggs to develop in micro gravity and mice fail to reproduce and get pregnant; that's all we have to go on at this time. Spiders, ants and most plants are just fine though, if it is an issue it only seems to effect vertebrates.

Fricken amazing joe...just amazing

One of the most interesting concepts that was explored recently in science fiction is the concept of a ring ship, where the WHOLE SHIP is rotating. Including the engine block. I'm talking about the Endurance in Interstellar. In all the previous movies and in the literature in general, we imagine a ship with a static (non-rotating) center core with engines, and then a rotating ring attached to it. There are major issues with these designs. The rotating ring needs to have a rotating airlock with the center core, which is a nightmare of engineering. And you have a rotating thing with mechanical parts and lubricants. So The Endurance's design makes much more sense. Make the whole ship rotate. Any ship with multiple rocket engines can be easily controlled by computers. Without the assistance of computers, it would be hell to pilot. But it's true for most designs anyway.

@tsamoka6496

That is a fantastic idea. The only problem would be the faster you accelerate forwards, the more the "gravity" of the ship moves towards the engines. Imagine standing on a 45 degree angle relative to both the floor and the wall! I'm sure there could be some way of dealing with this, but it certainly would be a crazy experience. =^x^=

Artificial gravity has to happen, because among other things we need it on a cellular level to survive in the long run, so we need it to stay alive in space and on other planets. With that said, I'm leaning towards quantum mechanics getting us to the sweet spot technologically...might be worth looking into.

"Whoa...This is heavy" "There's that word again. "Heavy." Why are things so heavy in the future? Is there a problem with the Earth's gravitational pull?"

There have been quite a few experiments on ring stations, and much head scratching. The current thinking is that human beings would adapt to rotational gravity fairly quickly, even at the scale of 100 meters. There is no excuse for not having a rotating station in place already. The experiments and next step knowledge we would have could be astoundingly valuable, and the deadly effects of microgravity would be eliminated.

Thank the stars for the insanely rich/insanely curious!

Good explanation !!

In a wheel habitat "hotel" 100 m in radius, spun to produce 1 g at 100 m, you would also have 0.38 at 38 m, 0.15 at 15m. One would have those levels where people could become acclimated to Earth, Mars, or Moon gravity as appropriate to their next destination. At the 100m radius, the difference in gravity between your legs and head would be ~1%. But at 15m radius, the difference is ~7% which is probably too much - so another wheel of similar size but slower rotation might be needed.
