The Moon has been one of the most important theoretical stepping stones to our understanding of the universe. We’ve long understood that it could also be our literal stepping stone: humanity’s first destination beyond our atmosphere.

@pierfrancescopeperoni 20 днів тому
@@abxorb Knowing that for GPS to work general relativity corrections on the satellite clocks count more than special relativity, this should also be the case but even amplified, since the difference in gravitational field, compared to the Earth surface, is even larger on the moon than on the satellite, and the moon is slower than the satellite.
@kindlin 20 днів тому

Yes. "To an observer on the Moon, an Earth-based clock will appear to lose on average 58.7 microseconds per Earth-day with additional periodic variations."

Well, Charon probably doesn’t count anymore because Pluto is a dwarf planet these days…but Charon is crazy big compared to Pluto…
@michs342 21 день тому
Probably also because I have seen more and more astronomers calling it the Pluto-Charon system. So it seems that it is slowly tilting towards being considered a bi-planetary system instead of dwarf planet and moon. While it officially (as far as I know at least) is still classified as a planet and moon system that might change at some point in the near future. Which does make sense as the gravitational center of that system is somewhere between the two bodies instead of inside the bigger one as it is in all other planet-moon systems.

14:08 Doesn't time tick a tiny bit slower on earth compared to moon's surface?
@AthAthanasius 21 день тому
Yeah, this. 1) The Moon is further out of the Earth's gravity well than when you're on the surface of the Earth, so time will tick slower closer to the Earth, *especially* if you're following an Earth geodesic at the further distance, rather than resisting it as on the surface. 2) The Moon is following a geodesic with respect to the Earth, so shouldn't have any GR time dilation with respect to the Earth, right ? 3) If you're on the surface of the Moon, and thus not following a geodesic with respect to it you'll have GR time dilation there, but less than if on the surface of the Earth. And if we trust Wikipedia to have been well sourced, and those sources correctly interpreted: "The two main differences to timekeeping on Earth is the length of a day on the Moon, being the lunar day or lunar month, observable from Earth as the lunar phases, and the differences between Earth and the Moon of how differently fast time progresses, with 24 hours on the Moon being 58.7 microseconds faster," en.wikipedia.org/wiki/Timekeeping_on_the_Moon (the citation is www.theguardian.com/science/2024/apr/02/moon-nasa-coordinated-lunar-time which says "ecause there’s less gravity on the moon, time there moves a tad more quickly - 58.7 microseconds every day - compared with on Earth.", which should perhaps be taken with a pinch of salt, given the source).

@xymaryai8283 12 годин тому
the reason why Gateway is controversial is not because its in orbit, but which orbit it is in. it has much higher and more complicated orbit which achieves constant communication, but with such large tradeoff that its considered by some (and me) to be nearly infeasible for a gateway station. another of the main reasons it was chosen is because the rocket and capsule aren't actually capable of getting into more useful, low lunar orbit. which frankly, should call for a redesign.

Yes. Maybe we don't see alien empires colonizing the whole galaxy because none of them could figure out there was something to colonize up there in the first place. Would we have figured out that the planets of our solar system are more than just moving stars in the sky, if we didn't had our moon as an example of such object ? Would we have built tools to magnify these objects, if we didn't know there was actually something of interest to observe ? And then, how do you get to the idea of gravity, without these observations ? How do you get to relativity without a concept of gravity, and no way to test it without access to space ? How do you understand nuclear reactions without E=mc² ? How do you get from there to quantum physics, to electronics and the wide set of technological advancements those theories provided us with ? It may be that most alien societies in the galaxy are at best stuck at an industrial level, for the sole reason that they don't have such object in the sky to drive their curiosity. And it even may be that those societies, without access to space, wouldn't even realize the damage their activity do to their own environment, and are stuck in a cycle of societies rising and self-destructing.

I'm on board with the modeling of the terminal part of the collision that lead to the earth/moon. Now, the part I'm most interested in is how it got to that point. I would have expected the earth/mood to be a single combined object. What was different here? If the two parts were in the same general orbital zone of the protoplanetary disk, then why were they not combined from the start? If one part - realistically there were many, many parts - came from much closer or much further away from the sun, then how did it end up around our area? Outside, or very eccentric orbit, seems most plausible, but then I would have expected Jupiter or Saturn to have soaked up those sorts of objects. Whatever happened, it seems to have been unusual and big. Venus and Uranus spin in the wrong direction. Something happened. Now it's a question of what happened.

There are many great reasons for why there is a Lunar Gateway as part of future lunar exploratory plans. Most important is for planetary protection protocols. A gateway serves as a buffer to control what moves between the Moon and Earth. A gateway enables supplies and logistics management. This similar to how the basecamp for Mt. Everest reduces risks to climbers venturing further up the mountain. Additionally, astronauts can use the gateway to study materials and the moon from an orbital vantage point, serving a number of landing sites on the moon.

An important thing about the Gateway is that the NRHO orbit it is in has the lowest ∆V requirements to enter and exit from interplanetary space. So its an ideal location from which to launch and receive anything from samples to a full Mars transfer vehicle (parts of which are to be prototyped on Gateway) which are also much easier to re-use.

'BATTERYLESS BATTERIES': To help power equipment in outer space: Potential endless energy source basically anywhere in this universe: a. Small aluminum cones with an electrical wire running through the center of the cones, cones spaced apart (not touching I'm thinking) but end to end. b. Electromagentic radiation energy in the atmosphere interacts with the aluminum cones. c. Jostled atoms and molecules in the cone eventually have some electrons try to get away from other electrons of which those electrons gather at the larger end of the cone, of which also creates an area of positive charge at the smaller end of the cone. d. The electron's in the wire are attracted to the positive end of the cone and the positive 'end' in the wire are attracted to the negatively charged end of the cone. e. Basically a 'battery' has been created inside the electrical wire itself, different areas of electrical potential. Basically a 'wire battery' or a 'batteryless battery', however one wanted to call it. f. Numerous cones placed end to end increases the number of 'batteries' in the wire. (In series to increase voltage, in parallel to increase amperage). * Via QED (Quantum Electro Dynamics) whereby electromagnetism interacts with electrons in atoms and molecules, one would have to find the correct 'em' frequency for the correct material being utilized for the cones. The shape of the cones could also come into play. The type and size of the wire as well as the type and thickness of the insulation between the cones and the wire would also be factors. * Of course also, possibly 2D triangles made up of certain materials with a conductor going down through the center of the triangle could possible achieve the same 'batteryless' battery system. * Plus possibly with the 2D concept, layered 2D's that absorb different energy frequencies, thereby increasing the net output.

@jameshart2622 21 день тому
@@AnubisDaJackal A quick Google search suggests that the relative rate of time on things in orbits depends on the orbit itself. There are two effects in play: gravitational time dilation, where things deeper in a gravitation well have their clocks tick slower compared to clocks less deep in the well, and "special relativity" time dilation, where the fact that the clock in orbit is moving relative to Earth slows its tick. For low orbits, it's slightly less deep in the gravity well (which makes the clock tick faster relative to the surface) but has to move pretty fast to stay in orbit (which slows the tick down relative to Earth) and it works out to a relative slower tick. For higher orbits, though, you both get out of the gravitational well, and need less speed to stay in orbit, and so eventually the gravitational effect wins. I think the Moon is well outside of that range.
