| Question from my 5 year old. Would Gatorade keep you hydrated better than water? Posted: 18 Sep 2019 04:33 PM PDT He has older brothers and one of them explained that you can live much longer without food than water and he's been interested in this topic (for the last week at least). So I think what he is asking, when compared 1:1, water vs Gatorade, would Gatorade keep you hydrated longer than water in a situation where resources are sparse? I guess I'm also interested in the aspect of 'better'. Is there a 'better' in a situation like that? Would Gatorade keep you in better health if you had one a day in that situation? I'm guessing you wouldn't want to overdo it? Climate would play a big role I assume? In a hot climate, Gatorade would help you replenish electrolytes lost due to sweating? I would probably also assume a person of average health since my guess is certain health conditions would impact this as well. [link] [comments]  |

| Posted: 19 Sep 2019 01:48 AM PDT I saw lots of references to the theorised graviton and apparently lots of physicists are searching for ways to detect it; a graviton should exist if gravity is one of the fundamental forces, at the same time gravity is defined as just space being bent, so why is gravity classified as a fundamental force when in fact it's not a force but rather a consequence of the fact that space is being bent ? The way I understand it, gravity's force is just an illusion, space's bent and mass is falling towards the biggest object responsible for the space curvature, so why should a graviton exist in this case?

| Can someone explain time crystals and what they mean for the future? Posted: 19 Sep 2019 12:13 AM PDT In laymen's terms I understand but I'd really like more information that is hard to find. On top of that question I would also like to know.
I am very excited about this topic and would like to thank anyone in advance who can shed some light on this subject! [link] [comments]  |

| Is it better to "push" an asteroid to alter it's trajectory, or "slam" into it? Posted: 18 Sep 2019 09:34 PM PDT With the recent news of AIDA (Asteroid Intercept and Deflection Assessment) - I wondered... Is it more effective to slam into an asteroid at the greatest velocity+mass you can manage or would it be more effective to LAND on the asteroid and anchor rockets to it and PUSH it over time to deflect?

| Is there a way to cut an equilateral triangle in such a way that every piece would be a square? Posted: 18 Sep 2019 11:36 PM PDT This is assuming a triangle of any size and with an infinite amount of cuts available. [link] [comments]  |
| Posted: 18 Sep 2019 11:08 PM PDT Inspired by https://en.m.wikipedia.org/wiki/Brave_(web_browser), last paragraph of the History section. "In June 2019 Brave started testing new ad-blocking rule matching algorithm implemented in Rust that Brave claims is on average 69 times faster than the previous implementation in C++. The new algorithm is inspired by uBlock Origin and Ghostery algorithms." [link] [comments]  |
| A couple universe related questions from a layman - can you explain any of these things? Posted: 18 Sep 2019 08:42 PM PDT I might have done some thought gymnastics to come to weird ideas regarding this, so please bear with me. If energy is finite, wouldn't the universe be finite? If energy is infinite, wouldn't the universe be infinite? If energy is finite, wouldn't matter be diluting as an infinite universe expands? If the universe expands, there's more space with every single second passing. More space would require more matter, since an absolute negative pressure/vacuum isn't possible (iirc). Respectively, since "regular" matter doesn't really seem to be filling these massive voids, something else would be filling it, which (from my understanding) would be dark matter. So how does dark matter not dilute as the universe expands? If the universe was somehow generating more dark matter as it expands, wouldn't there also be a possibility that it would keep generating just as much "regular" matter? If the universe came from nothing, and all energy can be neither created or destroyed, just changed, then the universe would contain a total energy of zero. If light, "regular" matter, etc. are considered positive energy, what is actual negative energy? And what use is there for the universe in particles and anti-particles constantly nullifying each other everywhere, all the time? [link] [comments]  |
| In a spinning black hole, what's actually spinning? Posted: 18 Sep 2019 04:44 PM PDT Is the singularity spinning? If so does it even matter considering it's dimensionless? Is everything inside the event horizon spinning? Can we consider the matter that hasn't yet arrived at the singularity actually even moving in a direction that isn't directly straight to it? I understand that a black hole has a mass but it's hard to visualizing it as actually spinning given it's basically just a value more than a physical piece of matter somewhere, or even sometime [link] [comments]  |
| Can somebody explain MWI to me in layman’s terms ? Posted: 18 Sep 2019 03:50 PM PDT I understand that an electron can be in superposition. The act of observing the electron causes the universe to be split in two where one observer sees spin up, the other spin down. I understand the Schrödinger's cat experiment that the cat can be both alive and dead until the moment of opening the box. What I CAN'T get my head around is how any of the quantum observations has anything to do with me or any other macro scale object in the universe. How does the superposition of an electron mean that there is a universe where I had cereal for breakfast and one where I had toast? I thought that quantum mechanics does not interfere with classical physics? Or is MWI simply stating that whenever two or more options is possible, all exist in some state. Does that mean everything in the universe is in superposition? Totally lost. [link] [comments]  |

| How is it that all computer code is not effectively "open source", since binaries can be read? Posted: 18 Sep 2019 11:17 AM PDT Computer code is usually written in a "higher-level" language such as C and compiled into the binary machine language that computers actually understand. This machine code can presumably be read by anyone with the know-how and access to the machine running it. If that is the case, couldn't all software be de-compiled back to a higher-level state where it could be analyzed and understood? Does this not effectively make all software "open source" regardless of whether or not the original creator releases the source as written in a higher-level language? [link] [comments]  |
| Does a female express/pass on epigenetic changes in their germ cells? Posted: 18 Sep 2019 06:44 PM PDT I understand that males can pass on some of their epigenetic changes through their germ cells, but I don't understand why I haven't seen something about females doing this. Is it because females are born with a complete set of eggs, whereas men continue to produce sperm? Or is it because females can already incite epigenetic changes during pregnancy? Does a female express/pass on epigenetic changes in their germ cells? If so, how? (Putting all of this in the title would be too much, so I only used the last line.) [link] [comments]  |
| Posted: 18 Sep 2019 04:06 PM PDT Do these subatomic particles have their own mass? And as the universe approaches its heat death after only black holes exist, what happens to these particles? Do they evaporate too? My dad and I have been struggling to understand this for a while now and can't seem to figure it out. Nothing on google seems to be providing an answer either. All the articles state that this process happens and that these particles are called Hawking radiation, but nothing describes it in terms of what I've asked above. Edit: spelling [link] [comments]  |
| How did the video aspect ratios come to be? Posted: 18 Sep 2019 08:59 AM PDT I mean specifically why did we end up on 16:9. Was it just because it looked nice? I know previous ratios were smaller, but specifically why not something like 2:1? [link] [comments]  |
| Posted: 18 Sep 2019 06:16 PM PDT In other words, if you zoomed way in on an atom, would things be sized proportionately to a solar system, like a scale model? With vast distances between the tiny protons and the nucleus? (They say matter is mostly empty space).And if you zoomed out far enough, would all the quadrillions of solar systems/galaxies resemble atomic structures? Or are the distances vastly unproportional? My uneducated guess is NO, distances between planets and their suns are far greater (I'm talking in relative terms, I'm aware that planets are bigger than atoms :p) But I also wonder if the cosmos and molecular level don't look pretty similar on vastly different scales. It would seem to make sense that the universe self-organizes itself in similar ways across the spectrum of "scale". (There should be a word for this spectrum)..I've always wondered what it would look like if you just kept zooming in further and further, smaller and smaller, beyond the atomic level, and conversely, if you just kept zooming outward and outward until the galaxies were a speck...what you would see..I'll save it for my next post, if I don't get banned for not posting this in r/Explainlikeimfive [link] [comments]  |
| Do negative and positive electro magnetic charges have any distinct differences? Posted: 18 Sep 2019 12:51 PM PDT For example, would an anti matter/negative charge version of our universe have any differences other than reverse charges? If not, does that mean an anti matter universe is indistinguishable from its matter equivalent without the other one for comparison (sorta like how you don't know what a superposition is)? If a counterpart universe is even possible on the quantum math level, like in the no cloning theorem, which would make sense if they had distinct differences because if scientists in the other universe had opposite results on the charge of their universe, then they can't be virtually identical, unless its a moment of time that's not the instant the method of discovery is used or something like that. And the same question about color charge and up-down? [link] [comments]  |
