Does dark energy actually exert a force? Is it actually energy? Posted: 24 Mar 2019 03:38 AM PDT Been reading about this recently and I'm a little confused as to how it's supposed to work. If every point is expanding from every other point, how can any quantifiable value of force be determined for it? If it's actually antigravity -something like negative mass particles appearing with vacuum energy and annihilating or whatever- doesn't that break causality because negative mass allows stuff like building FTL drives? Articles also say it's a force being exerted on the fabric of the universe itself, but is that quantifiable too? Is there a type of energy you can exert that actually does that? submitted by /u/saramiie [link] [comments]

What is the smallest organism capable of learning? Posted: 23 Mar 2019 06:45 AM PDT From my understanding most microbes interact with their environment but are not capable of pattern recognition or learning based on experience. They simply react as they were programmed to by their DNA. Mice can be taught to run mazes. I want to know what is the smallest creature that has been shown to have intelligence or learning capabilities. submitted by /u/Otterchaoss03 [link] [comments]

Are there any female animals that can delay or suppress ovulation or sexual maturity in insuitable environments? Posted: 24 Mar 2019 01:07 AM PDT As the title says, I'm sure I heard/read/saw somewhere that some animals won't go into heat or ovulate or mature sexually if the external environments are unsuitable, such as no suitable breeding males, insufficient food or other issues. If so, is there a term for this suppressed ovulation or delayed sexual maturity? submitted by /u/FarewellMyQueen [link] [comments]

Has anyone ever witnessed a star death ? Posted: 23 Mar 2019 12:07 PM PDT I understand the time difference of how long it takes light to come to Earth from stars, galaxies, and other wonders of the night sky.

Can dogs appreciate music? Posted: 23 Mar 2019 07:08 AM PDT This is one that's been on my mind a lot lately. So I play piano and whenever I play, my dog wouldn't leave the room or anything, would just sit there and sometimes even comes in while I'm playing. I find it strange as if there is any erratic, unusual noise like a loud piano note she is fine but if I watch rugby and shout or any other loud noise she would leave the room. It would be the same if I'm listening to loud music. I'm just wondering if that's just something to do with her being able to tell the mood of the situation or if she has an appreciation for music or is neutral with it, super confused please help. submitted by /u/ansomenes [link] [comments]

What physical limits exist on the sending and receiving of digital data? How quickly can discrete bits be pushed and received before they are no longer discrete? Posted: 23 Mar 2019 07:42 AM PDT It seems like there is a high upper limit to how much data can be transmitted simply by adding channels and increasing bandwidth, but wouldn't the harder, lower limit be on how quickly pulses can be generated/received whilst remaining intelligible? submitted by /u/RockleyBob [link] [comments]

How much energy does an average post on social media take? Posted: 23 Mar 2019 09:42 PM PDT This is more about the amount of energy the servers that belong to these companies (Facebook, Twitter, YouTube, Reddit, Instagram) take to store and retrieve a post. If there are estimates which include energy expenditure on clients' devices too, that would be nice. I realize that each of these platforms have different types of posts which would probably account for most of the difference in energy expenditure (an average YouTube video probably takes more energy than an average tweet). Nevertheless, I thought it'd be interesting to know how our content on social media is adding up to our carbon footprint. And should we be worried that some of this footprint is not insignificant, that we might probably be better off not posting? I also realize the irony of making this post, but i guess curiosity got the better of me. submitted by /u/bowdangatip [link] [comments]

In string theory, spacetime is emergent. Are strings and branes fundamental? Posted: 22 Mar 2019 07:49 PM PDT In string theory, strings and branes are fundamental and not made of anything more fundamental (or so I thought) but string theorists like Susskind and Greene say spacetime is not fundamental but emergent from something else.

Why doesn't an electron just fall down onto the nucleus? Posted: 22 Mar 2019 02:20 PM PDT I'm a sociologist by education but I've been feeling ashamed of not being as in the know about natural sciences lately so I'm basically re-educating myself through the entire school curriculum in my free time. This time I am having trouble understanding how atom works. I googled a lot of smart stuff but it was apparently too smart for me and now my brain is full of conflicting things. So, I learned that the planetary model of the atom that we're taught in school is a gross oversimplification and is wrong. Atoms are not small negatively charged spheres flying in circles around a bunch of positively charged spheres. They're more like a spherical cloud of positively charged probabilities surrounded by a shell-shaped cloud of negatively charged probabilities. But they still have charge, and are still attracted towards each other, no? Why would their shape change anything, won't the clouds still get squished towards each other? All I've read about it online has too many formulas for my feeble social sciences brain and more or less boils down to uncertainty principle. As in, the closer an electron is to the nucleus, the more defined its position becomes, therefore its momentum becomes less defined. In other words, the more we know about its location, the faster it becomes. But how getting faster would change anything? Won't that mean that you're just going down faster? Another thing I've found on the topic is that a sum of an electron and a proton is less in mass than a neutron. Is that's why? The nature just doesn't have any ways for an electron and a proton to interact other than turning into a neutron so unless extra energy is supplied from the outside, the electron just politely waits by the nucleus? And anyway, I remember reading that particles like to occupy the lowest possible energy state and somehow, for an electron it's in the middle between being too far from a nucleus and too close to a nucleus. But that sounds fishy to me, won't it actually be less energetic for negative and positive charges to just cancel out and be done away with the energy completely? The way I see it, there must be some force balancing out the electromagnetic one pulling the differently charged particles together. It can't be strong nuclear force since it doesn't affect electrons. Is it the degeneracy pressure thingamabob caused by Pauli exclusion principle? Since two fermions can't occupy the same place, when the fuzzy edges of probability clouds that are particles start touching they're repelled and that's what balances the electromagnetic attraction? Please help, I just don't understand why don't we all and all known Universe just doesn't collapse onto itself. submitted by /u/MajesticS7777 [link] [comments]

Posted: 22 Mar 2019 12:09 PM PDT Surplus killing, as in the behavior in which animals kill things they don't immediately intend to eat, is most common in mammals to my understanding.

How is sublimation (The change in a state of matter from solid to gas) possible? Posted: 22 Mar 2019 11:31 AM PDT From my understanding, the state of a type of matter depends on how the atoms around each other move. atoms in a solid do not move, atoms in a liquid slide around one another, and atoms in a gas move about freely. So how can an atom sublimate from a certain matter moving straight from solid to gas? Wouldn't it at some point have to become a liquid first? Even if for the tiniest fraction of a second? submitted by /u/McPresh [link] [comments]

How are satellite images captured and edited? Posted: 22 Mar 2019 10:31 AM PDT How are satellite images captured and edited? What different censors are there and what is done to the raw data? Most of the images look like they're color corrected and originally false color, for example - is that correct? I'm especially interested in the question if there are any satellites equipped conventional modern high-res censors, as opposed to spectral imaging or other purely scientific methods, as I couldn't find any beyond what's been taken in LEO from the ISS. I understand this wouldn't make much sense from a research standpoint, but surely there must be some interest in seeing the earth as it would appear to a human observer. submitted by /u/giraffenmensch [link] [comments]

Is the amplitude of a light wave equivalent to the number of photons being given off and the frequency of a light wave equivalent to the kinetic energy of each photon?

From what I've gathered the amplitude would be the number of photons being given off and the frequency would be the amount of energy per photon? There really isn't any material that explains this concisely. Would this model be correct? submitted by /u/msarn5150 [link] [comments]

Would the Higgs Field reaching true vacuum state be catastrophic for us no matter when/where it occurred, or are there distances at which it could happen and its effects never reach us, due to propagating too slowly to overcome the rate of universal expansion? Posted: 22 Mar 2019 01:21 AM PDT I just watched the Kurzgesagt video about the Higgs Field and true vacuum state, and it made me think of a question. I am a writer and linguist, not even remotely close to any kind of a physicist, so please bear with my rudimentary understanding of the concepts. What I want to know is this: if the Higgs Field reached true vacuum state in some vastly distant region of spacetime from our own -- say 30,000 years ago beyond the edge of our galactic supercluster or the edge of our known universe, could it possibly propagate fast enough to cause us or our descendants trouble? If it occurred outside the limits of our known universe, could it even reach us before the heat death of the universe? If so, what would the timeframes look like? If not, would it just be an isolated hole (in our familiar version of the laws of physics) forever? submitted by /u/manicdouchebag [link] [comments]

Is it possible to navigate without GPS and satellites using the earth's geomagnetic field instead (like birds do)? Posted: 22 Mar 2019 07:32 AM PDT I was reading about birds sense of Biomagnetism and was wondering myself if there was a way to use earth's magnetic field to navigate and determine latitude or even longitude.

Are there sensors around that can measure the geomagnetic field more accurately, making something like a satellite independent navigation system possible? submitted by /u/cycleburger [link] [comments]

If an object that creates light is travelling through space at light speed what happens to the light traveling in the same direction? Posted: 22 Mar 2019 07:16 AM PDT Does the speed of said object allow for a sort of faster than light "light" (redundant I know) for the light travelling in the same direction or would the energy/light just accumulate on the surface of the object in that direction assuming the speed of light is constant.

Relations between gluons, Quarks and Anti-quarks? Posted: 22 Mar 2019 06:35 AM PDT I have heard that gluons, which are made up of a colour and an anti-colour, can, at any point, turn into a quark and an anti-quark and vice-versa. But, the mass of a gluon is zero, whereas the mass of an UP quark is 2.4MeV/c² and that of an anti UP quark is also 2.4MeV/c² (not -ve as that would be exotic matter). So, how does this make sense in terms of the law of conservation of energy/mass? submitted by /u/Deciperer [link] [comments]

Do metal pipes, say copper, which have pressure fluctuations over long periods of time, eventually work harden and become more brittle? Posted: 21 Mar 2019 08:44 PM PDT I was just thinking how pipes have pressure changes all the time and if would make a difference on reusability without reheating and annealing if you wanted to bend old pipes. Or for say power lines, which take wind strain, could they get brittle over time and break? There are some beautiful old copper power lines in Toronto where you can see the green of the copper oxide on them if you look closely, the tar and woven casing long rotted away.
