RIP Kepler Megathread Posted: 30 Oct 2018 10:27 PM PDT After decades of planning and a long nine years in space, NASA is retiring the Kepler Space Telescope as it has run out of the fuel it needs to continue science operations.We now know the Galaxy to be filled with planets, many more planets existing than stars, and many very different from what we see in our own Solar System. And so, sadly we all must say goodbye to this incredibly successful and fantastic mission and telescope. If you have questions about the mission or the science, ask them here!

If the Hubble telescope can see 10-15 billion lightyears away, wouldn't that mean it could witness the universe before the Big Bang? Posted: 31 Oct 2018 01:20 AM PDT If light travels at the speed of light, and the Hubble is able to see objects 10-15 billion lightyears away, wouldn't light from that 10-15 billion years be what it would witness? If the Big Bang happened 13.5 billion years ago, then how would the Hubble be able to (essentially) see light from 15 billion years ago?? And could this be used to witness the early stages of the Big Bang? submitted by /u/DismalAlternative [link] [comments]

Ask Anything Wednesday - Biology, Chemistry, Neuroscience, Medicine, Psychology Posted: 31 Oct 2018 08:12 AM PDT Welcome to our weekly feature, Ask Anything Wednesday - this week we are focusing on Biology, Chemistry, Neuroscience, Medicine, Psychology Do you have a question within these topics you weren't sure was worth submitting? Is something a bit too speculative for a typical /r/AskScience post? No question is too big or small for AAW. In this thread you can ask any science-related question! Things like: "What would happen if...", "How will the future...", "If all the rules for 'X' were different...", "Why does my...". Asking Questions: Please post your question as a top-level response to this, and our team of panellists will be here to answer and discuss your questions. The other topic areas will appear in future Ask Anything Wednesdays, so if you have other questions not covered by this weeks theme please either hold on to it until those topics come around, or go and post over in our sister subreddit /r/AskScienceDiscussion , where every day is Ask Anything Wednesday!

[Mathematics] Equivalent of the maximal torus theorem for finite groups? Posted: 31 Oct 2018 04:52 AM PDT In the theory of Lie groups there's a really nice theorem which states that if G is a compact connected Lie group, and T<G is a maximal torus, then every element of G is conjugate to an element of T. Does this theorem also hold for finite groups? (Replacing maximal torus with maximal Abelian subgroup). I'm interested in particular in the case of the finite symplectic group over GF(p) where p is a prime. I've looked hard into the literature, but it's pretty dense so if somebody could point me to where to find the answer, it would be super useful! submitted by /u/fuckwatergivemewine [link] [comments]

What is still? Posted: 30 Oct 2018 10:08 PM PDT When people study time travel they always reference the movement of the earth in the solar system and the solar systems movement in the galaxy but how do we know what is or isn't moving, since the only reference points we have are other objects? The ISS is orbiting earth, which is orbiting the sun, which Is part of material that is orbiting a theoretical supermassive black hole in space. Anytime we move in a ship or suit we state out movement speed in metered per second usually. These speeds are all relative to other celestial bodies though. Such as moving 1000 kilometers per hour away from earth. When floating in space, no matter the speed, without anything moving past us, wouldn't we theoretically think we were sitting still? Additionally, is there some kind of test to tell if matter has any directional force of if it is completely still? If all of this is a thing, what is it called? submitted by /u/Drewbixtx [link] [comments]

Can quantum effects be observed on a macroscopic scale? Posted: 30 Oct 2018 11:50 AM PDT For example, is there an extremely small probability that all of the particles in one object become entangled with all the particles of a different object?

Why do humans tend to raise their pinky finger while holding items like bottles or cups? Posted: 30 Oct 2018 07:17 PM PDT I noticed it's sort of a joke to be "fancy" by raising your pinky finger, but I catch myself and others doing it instinctively all the time when drinking or holding objects in a like manner.

Why are reactive materials often stored under argon but rarely ever helium? Posted: 30 Oct 2018 07:27 PM PDT Both gases are fairly cheap (argon is 1% of the atmosphere and helium is widely available.), so cost likely isn't a factor. Does it have to do with atom size and helium being able to more easily "escape" than argon? submitted by /u/GalliumGames [link] [comments]

Polarizing filters are useful in normal environments- so why isn't the polarization of the environment random to begin with? Posted: 30 Oct 2018 06:49 PM PDT You can use a polarizing filter to reduce some glare from the sun off the surface of a lake. Why would the light from the sun all have the same polarity to begin with? Why would the rocks under the surface of the lake be reflecting sunlight not matching the polarity of that of the surface? Is the surface itself preferentially reflecting one polarity, and if so, why? edit: I don't find it so strange for hard surfaces that might have preferred directions, some grain or fiber... but water, how? submitted by /u/dungpuck [link] [comments]

Why is language gender a thing in some languages but not others? Posted: 30 Oct 2018 06:39 AM PDT I'm a native English speaker, but I am now starting to learn Spanish. English doesn't have [many?] gendered words (other than pronouns like "he" and "she"), but Spanish is full of gendered words -- even "a" = "un" and "una", and "the" = "el" and "la".

How important is water to the composition of lava? Posted: 30 Oct 2018 05:15 PM PDT A friend and I recently got into a debate on lava composition (of all things). He stressed in his argument that "lava is made of water," while I argued that "lava is for all intents and purposes made entirely of molten rock." Google searches told me that there is some water vapor dissolved in magma, but is it really so significant a component to say that "lava is made of water?"

Why isn't Psychopathy/Sociopathy in the DSM-5? Posted: 29 Oct 2018 10:20 AM PDT Although the DSM-5 has "Antisocial Personality Disorder", this seems to be much more based on the impulsive criminal behavior clinicians come across in the criminal population and disregards the functional psychopaths and sociopaths in society. People with Dependent Personality Disorder and Narcissistic Personality Disorder (for example) can also be fully functional in society, yet they get the "benefit" of a diagnosis. So why has Psychopathy/Sociopathy been dismissed? EDIT: lots of interesting information, but very little actually addresses my question directly. EDIT 2: iglet007 gives a great answer. Read it. submitted by /u/kuuzo [link] [comments]

Do animals have different "names" for their offspring the way humans do? Posted: 29 Oct 2018 05:06 AM PDT Intuitively, it seems like it would be helpful for many mammals (e.g. lions, bears, dogs) and even some birds to be able to tell their offspring apart, in order to attend to each one's unique needs. submitted by /u/KnightsWhoSayKni [link] [comments]

Was the eruption of Krakatoa really heard ~3000 miles away? Posted: 29 Oct 2018 10:16 PM PDT The 1883 eruption of Krakatoa was noted to be heard up to 3000 miles away and sound waves circled the earth four times. However, this paper suggests the eruption was ~180 decibels, which while deafening, is not much higher than being near a jet engine (noted in the same paper), and is less than what was estimated for the Saturn V launch at around 200 dB. Is this due to a sustained output of sound from the eruption, or do I really not understand sound as well as I think I do? submitted by /u/jonwku [link] [comments]

How does visual stimuli get stored in genes and subsequently expressed in the brain? (For example, the innate fear of spiders, &/or possible sexual stimuli.) Posted: 29 Oct 2018 02:59 PM PDT I'm talking about things like innate fear of spiders: https://news.nationalgeographic.com/2017/10/infant-fear-phobia-science-snakes-video-spd/ This only seems possible if the brain has "preprogrammed software." Its seems like an image of a spider (or a visual form) has to exist in the mind at birth. It sounds like a memory has gotten passed down from a previous generation. But that is a Lamarckian idea which is generally debunked. How does a gene encode a visual stimuli? Let's say memory cannot be passed down. This would mean there are genes that produce innate fear in random visual stimuli, and the spider-looking-stimuli so happened to get evolutionary selected? i) That seems statistically unlikely. ii) It seems to imply that we would have a storage of innate fears for other random stimuli. We do not have such a storage. I am also curious if sexual visual stimuli is innate (and expressed at puberty.) I am also curious how the brain determines what defining characteristic of a vision is the necessary threshold to trigger fear or desire. submitted by /u/band_in_DC [link] [comments]

What is information in the context of Physics? Posted: 30 Oct 2018 06:19 AM PDT My question is: is information considered a physical property of the Universe or of it's objects in a modern Physics setting? If so, what is the definition of information, and how does it relate to other properties? Context: I've seen information (measured in bits) come up in some Physics discussions and articles in Wikipedia. For example: the Maxwel's Devil thought experiment seems to lead to a situation where the 2nd Law of Thermodynamics is disrespected, until you consider that adquiring information about a system requires spending of energy. That is reasonable, but the amount of energy to information is calculated. How can this be? Also, I've seen information being brought up in discussions about black holes, but that subject is way beyond my league. I think I have an ok qualitative understanding of modern Physics, but a small and vague quantitative (math) understanding. So maybe this question doesn't even make sense, or maybe the answer can only be understood with a lot of math. I'm sorry if that's the case. submitted by /u/sapirus-whorfia [link] [comments]

Do protons and electrons orbit around a barycenter? Like gravitationally attracting bodies? Or does the electron strictly orbit the centre of a proton? Posted: 29 Oct 2018 07:13 PM PDT I suppose in atoms other than H and He, the increase in the number of electrons at different places would nullify the barycenter thing. But what about when there is only 1 proton and electron(like in Hydrogen and Helium)? submitted by /u/sthornr [link] [comments]

Why does salt decrease the specific heat capcity of water? Posted: 29 Oct 2018 10:30 PM PDT As such, how is specific heat capacity and cooling rate related? submitted by /u/edavidson912 [link] [comments]

Is sound effected by gravity? Posted: 29 Oct 2018 07:38 PM PDT For example that TIL on the front page states that a volcanic eruption in the 1880s could be heard 3,000 miles away and traveled around the world 4 times. This leads me to visualize the sound waves traveling across the earth much like the aftershock of a nuke. Is this a poor visualization? submitted by /u/JonathanJoestarJr [link] [comments]

What body parts can be donated by a typical dead person? Posted: 29 Oct 2018 11:27 AM PDT People are encouraged to become organ donors when they die, but it's my understanding that actual organs(heart, liver, kidneys etc) can only be harvested from brain-dead people whose bodies are kept alive on life support. What about ordinary dead bodies? What all can be harvested and used? submitted by /u/casualphilosopher1 [link] [comments]

Why do acetylene torches pop when they are shut off? Posted: 29 Oct 2018 07:30 PM PDT So I've recently gotten into metal working and one thing that I've wondered about is why do the acetylene torches pop? They pop when they're shut off (acetylene valve closed first) and sometimes when the torch head is too close to the material. I don't really know why this happens, but I have a theory. The gas that is left if the air is burned rapidly leaving a vacuum where the gas was. But I haven't been able to confirm or deny. submitted by /u/PCOverall [link] [comments]

How dangerous is nuclear waste compared to coal and other forms of energy like renewable sources? Posted: 29 Oct 2018 10:29 AM PDT Comparing the health & environmental impacts out of curiosity.

Why does the height of so many intraplate volcanic centers reach so close to sea-level? Posted: 29 Oct 2018 12:03 PM PDT I'm not referring to atoll construction, which allows the top of these structures to remain near sea-level despite erosion and other processes ... the top of these volcanic edifices has to reach the photic zone first. Many reach the photic zone without eroding away "en route", while msintaining a steep gradient and rising from the abyssal plain about 3 kms. How is it that volcanic activity allows to build these structures up to that height in the first place? Is it just that a bunch of geophysical and geochemical parameters just happened to fall in the right range for that combination to make it so, or is there something else at work here I might be missing? And of course, this only applies to oceanic plates. Continental plates are a different world. submitted by /u/Gargatua13013 [link] [comments]

Is there any evidence that recent (last 10,000 years) human activity has altered our eye physiology through evolution? Posted: 29 Oct 2018 06:34 AM PDT I saw an article in r/todayilearned that discussed animal eye evolution and physiology and how it pertains to specific needs re hunting and self defense. This article got me thinking about how modern humans engage in activities that have little in common with those of 10,000 years ago. http://advances.sciencemag.org/content/1/7/e1500391 For instance, when compared to humans living 10,000 years ago, there is significantly less need, from a modern worldwide perspective, for most people to need to scan the horizon (unassisted by technology) for predators. Also, modern humans spend much more time than previous ancestors using their eyes to scan close-range information (I.e. books, computers, or manual labor). Most people I know who interact with modern society require eyesight modifications (glasses, contact lenses, lasik, etc...) to see clearly. I do not know if this is a direct result of the way humans have altered the needs for use of their eyes over the years. Also, I do not know if there is any evidence that human eyes have evolved as a result of modern technology and a reliance on things that are "closer" rather than "farther". I cannot imagine that the change would be significant considering the short timeframe I am proposing, but I am curious none the less. Thank you. submitted by /u/spdorsey [link] [comments]

Do we actually know if bottling up your emotions is bad for you? Posted: 28 Oct 2018 07:05 PM PDT I always thought suppressing your emotions was bad for you, thats what id always hear from people, but in my psychology class some times ago i read about a study done with kids and a mean strict teacher (i might try looking up the study later). (to crudely paraphrase, during a break one half of the class was told to sit in a corner quietly and reflect, while the second half was told to punch a bag with a picture of the teachers face on it (or something like that), and after the break they were all given blow horns and told they could freely blow the horn in the teachers face, and they found the kids who quietly reflected would blow the horn less.) Anyways, after learning about this I tried looking up the answer online, came upon multiple opinion articles and sensational news sites which say it is harmful but would never cite anything, and the academic sources I found though were conflicting. submitted by /u/YeeeeeeeBoi [link] [comments]

Is there an extreme point where the temperature decreases with pressure rather than increase (gas)? Posted: 29 Oct 2018 04:13 AM PDT So, there's this: pV = nRT . From this is clear that if volume and number of molecules are constant, if we increase pressure the temperature has to increase. Is there a point when, if we increase the pressure to an immense threshold that there is actually a temperature drop because the molecules cannot almost move anymore? submitted by /u/Mintfriction [link] [comments]

Why is October so hot in some places in Asia, like in the city of Karachi near Arabian sea? Posted: 29 Oct 2018 02:58 AM PDT I don't quite understand why October is hot in certain places in the Asia. For example, recently I visited a friend in Karachi, which is a city in the south of Pakistan near Arabian sea and the whole October month was pretty hot although the previous few months of Sept, Aug, and July were not that bad. I Wikipedied October in that city and found: It is the second hottest month of the year after May. Karachi is considered by some to be a city with two summers. Pre monsoon summer of April–May and post monsoon summer of Sep–Oct. So why does it have post monsoon summer in October? I understand pre monsoon summer such as May being hot though, because May is hot in many places in the northern hemisphere. I just don't get the October thing. Some explanation would be appreciated. I think it has something to do with pressure in the atmosphere but don't know how it works exactly. I'm drawing blanks here. submitted by /u/Arrowsomeuser [link] [comments]

B) How is such a thin skin cut/excisioned out as treatment? C) How much scarring or ugliness or deformity is there in Biopsy? D) How much scarring or ugliness or deformity is there in cut out/excision treatment (which is the only treatment as I understand it)?

Will a mountain that is sufficiently tall create a 'bump' in the atmosphere? Posted: 28 Oct 2018 08:38 AM PDT The inspiration for this question came from this image over at the KSP subreddit. Disregard the skybox and look at the mountains sticking out pretty high, yet the atmosphere looks perfectly spherical despite the protruding mountain. I imagine that, just like a rock that's just underneath the water surface in a river, there would be a slight 'bump' in the local boundaries of the atmosphere if there'd be a mountain this high in real life. submitted by /u/_Enclose_ [link] [comments]

Is it possible to actually predict earthquakes to some degree? Posted: 28 Oct 2018 09:16 AM PDT I feel like you should be able to predict future rises in seismic activity based on previous activity, right? Or is it highly unpredictable? I don't mean predict an earthquake to the day, but something like "there is possibility of an earthquake of over X magnitude between 23rd of November and 30th of December". Would these predictions be highly unreliable or realistic? How exactly would you go about the prediction and monitoring? submitted by /u/anetanetanet [link] [comments]

Why does warming oceans release CO2, while simultanously acidifying due to carbonic acid from CO2? Posted: 28 Oct 2018 07:55 AM PDT I read a climate science study claiming as temperatures rise, CO2 increases in the atmosphere follows - A hot coke bottle was used an example. I don't understand why the oceans are acidifying, if CO2 leaves, it follows equlibirum would shift towards less carbonic acid in the water increasing pH. submitted by /u/bogcom [link] [comments]

When bleeding, how does the body regain the blood it has lost? How does the body actually create that blood and how does it know when to stop? Posted: 28 Oct 2018 05:01 AM PDT When you are bleeding, you lose blood. However, I was wondering how does the body actually regain blood lost? From what does it make blood, and what ensures that the mechanism does not make too much or too little. Is this different for different degress of injuries (papercut vs. amputation sort of thing...)? If there was too much blood in someone's body, does the body get rid of it? submitted by /u/ChocoGabz [link] [comments]

Why does AM wave produce sidebands?? Posted: 27 Oct 2018 10:47 PM PDT Amplitude modulation is varying the amplitude of a carrier based on the amplitude of the message signal by keeping the frequency of the carrier same, but in DSB AM waves, why do we consider the upper side band with freq fc+fm and lower side band with freq fc-fm, this is very confusing to me please explain, Thank you. :) submitted by /u/kx44 [link] [comments]
