- Relative to the moons in other planetary systems, is our moon really unusually big relative to Earth, and Jupiter/Saturn/etc's moons are normal relative to them, OR, (maybe?) is our moon relatively more normal-proportioned to us, and, say, Jupiter's moons are unusually small for it?

| What would happen if protons, neutrons, and electrons kept accumulating in a single atom? Posted: 08 Dec 2021 04:51 PM PST I read that the heaviest elements are produced artificially. What would happen if there was some environment, maybe inside or a star or some weird set of circumstances in space that caused particles that make an atom to keep accumulating "infinitely" or as long as possible. What would the resultant element be? Is there a prediction of the properties or such an element? [link] [comments] |

| Do sharks hurt their own stomach with their teeth during gastric eversion? Posted: 08 Dec 2021 03:07 PM PST I just found out about gastric eversion and the few pictures I could find the stomach clearly is in contact with their teeth, specially the sharks that have that first external roll poking out. Do they get hurt? Could that kill them? [link] [comments] |
| Posted: 08 Dec 2021 12:17 PM PST Hello peeps, I have a very basic yet bugging question about water boiling at different temperatures depending on different pressures. We know that in a vacuum chamber water starts boiling before it reaches 100 degrees Celsius. The same phenomenon happens if we boil water at sea level versus doing if on a high mountain. That is, the lower the pressure before it starts boiling. Again, I beg your pardon for this question as I intuitively understand it is extremely basic and possibly silly, but why we use pressure cookers then? Their function is to raise the pressure, thus making the water boiling faster. What am I understanding wrong? If their function was to raise the boiling point so as to cook the food at higher temperatures, that would be consistent with all the rest. However how come pressure cookers start boiling faster? Thanks or any help! [link] [comments] |

So, I always just assumed that it was like, Jupiter, Saturn, etc have normal sized moons relative to themselves, and we (Earth) are the weird one, with an unusually large moon, proportionally speaking. But, I was thinking about it, and how small of a sample size of planets we have at hand here in our solar system, and, maybe even more importantly, how small of a sample size of planetary systems we have up close and personal that we are inside of (just 1, that is... our own), so, that got me wondering: Do we know anything about the relative sizes of the moons of the planets of other planetary systems? Like, could it be that maybe it's the other way around, and it's not us that has the weirdly big moon, and instead, it's that planets as big as Jupiter and Saturn are "supposed" to have much larger moons than the ones they have in our Solar System right now? Or, maybe somewhere in between, like, Earth's still is a little unusually large, but not by as much as one might assume, and, Jupiter/Saturn's moons are a little on the small size, but not to too severe of a degree, or something like that? Occam's razor figures it to be more likely that we really do just have a weirdly big moon here, orbiting Earth, given even just the medium-low ish sample size of Jupiter/Saturn/Uranus/Neptune's largest moons vs our moon, to take at hand as what we (up until pretty recently, anyway) had to work with, from a statistical standpoint and just guessing based on that, in and of itself. So, I figure most likely the answer (if there is an answer available as of yet - not sure how good our data is on extra-solar moons so far) is going to be "nope, ours is indeed strangely large" But, I figured given the small-ish sample size and dynamics at hand here within our Solar System, there's still enough of a chance that maybe that's not the case, that I should still ask about it, just in case it isn't. So yea, how much (if anything) do we know about the moons of the planets of other planetary systems, especially in regards to their relative sizes relative to said planets? I know we can see the wobble-effect the planets have on other stars near us, to guess at the size of the planets orbiting said planet. But, have we been able to notice anything (at all) in regards to moons? (I figure it's a longshot, but I might as well ask). Also, getting away from the empirical side of things, too: what about on the theoretical side of things? Is there anything "theory-wise" (about how our Solar System formed, or how we think the early phases of planetary systems function) that might lead our hunches one way or the other in regards to this question, even if we didn't have any hard data on the moons of other planetary systems?

| What is the difference between compressive strength and bulk modulus? Posted: 08 Dec 2021 11:29 AM PST According to Wikipedia, bulk modulus is
According to Wikipedia, compressive strength is
What's the difference? It seems like both are the same thing - a measure of how resistant to being compressed something is - and yet, substances like aluminum oxide (Al2O3) have drastically different values for bulk modulus and compressive strength. Why? [link] [comments] |
| Do gas giants have a clear "edge"? Posted: 08 Dec 2021 01:47 AM PST I was wondering if gas giants had a clear distinct point where the planet starts and stops. Aside from the thin atmospheres that they have. Because in photos theres a clear distinction between the atmosphere and "surface" of the planet. Or do you just go in and after a while you realise "o shoot im in the planet" kinda like clouds? [link] [comments] |
