What is the radius of the targeting footprint of an average MIRV-capable nuclear ICBM? Posted: 06 Jul 2019 03:51 PM PDT I've been unable to find this information anywhere. I'm led to believe it's generally kept a secret. But I can't even find a guesstimate. What I'm referring to is the geographical land area that the warheads from a single MIRV delivery vehicle can be targeted over once it achieves the peak of its trajectory. For example could a single missile direct warheads to both New York and Chicago, or is the footprint smaller? submitted by /u/Dinyolhei [link] [comments]

How do nerves work exactly? Posted: 06 Jul 2019 10:14 AM PDT Since you never really touch anything and the sensation of touching is the force of your atoms pushing away from each other, what do the nerves "feel" or how do they work? Also how do we hold up objects if we never touch? submitted by /u/All_Might_Senpai [link] [comments]

Are victims of sexual abuse more likely to identify as something other than heterosexual and if so, why? Posted: 06 Jul 2019 06:55 AM PDT I work at a residential boys home with DCFS (Division of Child and Family Services). Our boys are victims of sexual abuse and have been removed from their homes for this and often other reasons. This is probably the only trait they all share. National stats say that about 5% of Americans identify as something other than heterosexual. However, out of our 16 boys, 10 of them openly identify as something other than heterosexual. Everything from Bisexual to transsexual. And that number is fairly low. It's common for us to only have one or two who identify as, and behave as, heterosexual. If their sexual identity was not at all tied to their past as victims of sexual trauma (again, the only trait I can think of that they all share), then you would expect their LGBT numbers to roughly match the national average because as far as that demographic is concerned, we'd be essentially taking a random sample from among them, but apparently we are not. The numbers hover more around 60-100% LGBT. I realize that even if we take every kid Ive ever worked with over my years in this job, it would still be a small sample size, but its enough of a pattern that it makes me wonder if theres any sort of connection. I remember a few years ago, there was a TIL that said that child victims of sexual abuse are 75% more likely to identify as something other than heterosexual, and theyre *usually* good about their sources there, but I cant find it now. Google only shows this article which is not exactly a reputable source and says that pedophiles target feminine children, but for some reason that seems unconvincing. Can anyone shed some light on why victims of sexual abuse seem to be much more likely to identify as something other than heterosexual? submitted by /u/Curlaub [link] [comments]

Does a computer do mistakes sometimes within the billions of operations they do every second? Posted: 06 Jul 2019 03:43 AM PDT It sounds insane to me such intricate circuits flawlessly execute all of these operations all the time correctly, but at the same time it also sounds strange to me the computer could function properly with mistakes within operations being a common thing. I don't think Fermi's approximation could work with computers, but I might be wrong. PS. I don't want a yes or no answer, but an elaboration, please. submitted by /u/bakedpotatos136 [link] [comments]

Is there a minimum time we need to touch something in order for our brain to process it and make us feel it?

Do nuclear fuel rods decay uniformly? Posted: 06 Jul 2019 02:10 AM PDT As I understand the whole point of a control rod is to limit the reaction by shielding some parts of the fuel more than others... wouldn't that cause the fuel to be spent unevenly? Do nuclear reactor operators rotate which control rods are utilized to even out the depletion? Or are the control rods pulled out progressively farther over time as the fuel decays? submitted by /u/kaosatang [link] [comments]

How is dietary citric acid metabolised in the human body? Posted: 06 Jul 2019 02:01 AM PDT Does it have anything to do with the citric acid cycle, or is it processed some other way?

How do we know the Mariana Trench is the deepest point in the ocean? Posted: 05 Jul 2019 06:05 PM PDT Pretty sure they taught this in school but can't seem to remember. If we haven't even explored the world's oceans in its entirety, how can we be sure that it's the lowest point?

High heat or radiation can change the color of quartz varieties, can the same hold true in glasses? Posted: 05 Jul 2019 07:22 PM PDT I don't know alot about the physics of glass color, but as I understand it, heat and or radiation modify the color of crystalline quartz by impacting how impurities (generally metallic cations) are arranged in the silicon dioxide lattice (through changes in coordination number, etc). Glass is not crystalline, but often derives its color from similar impurities. When treated with high heat or radiation, would the color of common types of glass also change? Additionally, if there are types of glass that would react, would they "streak" when near strong particle emitters of radiation? Thank you submitted by /u/Pohatu5 [link] [comments]

How high is Mars' Olympus Mons really? What's the reference point? Posted: 05 Jul 2019 10:39 AM PDT We usually measure mountains' heights on Earth relative to sea level, with Mt Everest reaching about 8848 m (I heard it's recently grown to ~ 8849 m). But what's the frame of reference for mountains on dry planets, like Olympus Mons on Mars?

Southern California Earthquake Megathread: Ask Your Earthquake Questions Here! Posted: 04 Jul 2019 04:32 PM PDT Hello AskScience! Today at approximately 10am local time, a 6.4-magnitude earthquake occurred in Southern California. The epicenter of the earthquake was in a remote area between Los Angeles and Las Vegas, though the quake was felt widely across the region. It is the strongest earthquake in the area in two decades. The AskScience team would like to extend our condolences to anyone negatively affected by this event. We are here to answer your earthquake questions! Please post them below and our panelists will join in. For more information, take a look at the USGS event page. Did you experience the earthquake or any aftershocks?

How far does sunlight travel through the atmosphere when I watch the sunset? Posted: 05 Jul 2019 07:44 AM PDT Hi, I got curious during some research on Rayleigh-scattering. I was wondering: If the sun appears red for us at sunrise and sunset, how much further does the light travel through the atmosphere for the shorter (blue-appearing) wavelenghts to be scattered to near-invisibility at mornings/evenings compared to noon? Let's just say noon means the sun is in zenith, the relevant atmospheric thickness is 15km, the horizon is 10km away and earth's radius is 6370km. I'm looking for the distance of an imaginery straight line between my eye and the top of the 15km high atmosphere, when the line is tangent to the 10km far away (from my eye) horizon. I don't really know how to calculate the distance. Any help is appreciated! (please excuse any grammatical errors, I'm not native english speaking) submitted by /u/SaItpeter [link] [comments]

What are the chances of a black hole being made from antimatter? Posted: 05 Jul 2019 06:04 AM PDT I've been thinking about the matter-antimatter discrepancy. How the Big Bang should have created both matter and antimatter in equal quantities, but the known universe contains only matter (so far as we can tell). After playing around with antimatter galaxies, I came up with the idea that black holes could be made from antimatter. Antimatter and matter explode violently upon contact, but nothing escapes the event horizon of a black hole (except Hawking Radiation). So if an anti-matter black hole captures matter, the explosion would be contained inside the black hole's event horizon and we'd never witness it. I realize that this could only happen if antimatter reacts more strongly to gravity than matter, thus making it more likely to form black holes in the first place. I realize that my idea is almost certainly wrong and it would be much easier to explain why more matter than antimatter was formed from the Big Bang (although there's currently no widely accepted reason why this would happen). But if there is an antimatter black hole a) would we be able to distinguish it from a matter black hole and b) would the obliteration of the matter-antimatter explosion cause the black hole to decay, by say, reducing the mass of the black hole and causing the gravity to weaken? submitted by /u/KnowanUKnow [link] [comments]

Are there any inherent issues with using tank tracks at high speeds? Posted: 05 Jul 2019 05:51 AM PDT Are tracks inherently limited to relatively slow speeds due to mechanical issues or is it more because the vehicles themselves are heavy? Even the fastest tracked vehicles such as the M18 Hellcat, the BT-7 or the FV 107 Scimitar weigh multiple tons due to armor, armament and other equipment. The question is, would it be feasible to create a "tracked sports car" with a lightweight chassis, a powerful engine and not much else to weigh it down or would issues with the tracks themselves (friction? wear?) effectively limit its speed? submitted by /u/EyeofEnder [link] [comments]

What does light look like as it moves away from the visible spectrum? Posted: 05 Jul 2019 01:04 AM PDT Let's say that we have created a kind of diode that can put off light on one and only one frequency at a time. We also have a knob that can precisely control what frequency the diode is emitting. This diode can also emit Ultraviolet and Infrared radiation (what a nifty little thing!). Oh, and it puts off light at a brightness that can easily be seen by the naked eye. My question is this: Given this hypothetical little diode, what would it look like as we turned the knob up to Infrared or down into Ultraviolet? Would the light just get dimmer and dimmer before going out? Since it is only emitting on one frequency, would it suddenly go out altogether? submitted by /u/SuPeR_J03 [link] [comments]

Is planting trees really a viable strategy to combat climate change? Isn’t all the carbon they capture released when the die/rot? Posted: 04 Jul 2019 10:27 PM PDT This recent article tours planting billions of trees as an option to fight climate change.

Rubbing these two metals together produces a sludge? Posted: 04 Jul 2019 09:06 AM PDT Hi, ​ I'm currently wondering why this happens over and over despite me cleaning those two metals every time. I'm fidgeting with two metals disks, rubbing them together with two fingers for no real reason. One disk is certainly made of Mu-metal or similar (Coming from a high-end speaker magnet. Is not a magnet itself.) and the other disk is made from a hard, cast iron (I can barely work it with a file), that is creating yellow salts in a oxalic acid peroxide solution. (I'm sure it's Iron oxalate) So it is mostly iron. The Mu-metal disk does not stick to the other disk, but it does when I've rubbed them together until the sludge appears. It holds on when turned on top. I am not touching the surfaces that rub together. I also ruled out charges because I rubbed them together while having them both connected via a copper cable. ​ The "sludge" appears as a darker-than-the-metal coating/film that also feels fatty. Kind regards ​ Edit: the Mu-metal disk could be coated in zinc. It is a pretty whiteish metal. Edit2: Interestingly, one disk slowly glides down the other when there is enough "sludge" to hold the disk when turned on top. For some reason it feels odd how it glides down. It is a very constant and slow motion. More: There is no magnetic attraction between the two at the point when they stick together. That's why I put this as a Chemistry question. submitted by /u/Distelzombie [link] [comments]

This would mean that our observable universe is getting larger every day. Is this the case? Posted: 04 Jul 2019 04:36 AM PDT The observable universe is the light that has managed to reach us in the 13.8 billion years the universe exists. Because light beyond there hasn't reached us yet, we can't see what's there. This is one of the biggest mysteries in the universe today. But, since the universe is getting older and new light reaches earth, shouldn't that mean that we see more new things of the universe every day.

Does Cygnus X-1 have a quasar? Posted: 03 Jul 2019 02:59 PM PDT For some reason, just when I think I've figured out what a quasar is, I get re-confused! I was to understand that quasars are a byproduct of supermassive black holes. Based on all of the illustrations I've seen of Cygnus X-1, it shows its jets on the poles which make me think quasar, but isn't Cygnus X-1 far too small to create a quasar? Are Cygnus X-1's jets something different than a quasar, or am I wrong on all fronts? submitted by /u/cmde44 [link] [comments]

How do/would we navigate in space? Posted: 03 Jul 2019 08:56 AM PDT Considered posting this to r/nostupidquestions but figured I wanted a more informed answer. As a layperson, I'd imagine that since we've only been to the moon, we'd just use visual orientation to align our spacecraft with the Earth and..."go that way". But how would we navigate back to Earth when it gets beyond sight and/or we leave the solar system? submitted by /u/Vyzantinist [link] [comments]
