Hein et al (2017) have explored scenarios for sending a spacecraft to the recently confirmed interstellar asteroid "Oumuamua". What payloads and capabilities would we wish to prioritize on the exploration of this strange and peculiar object? Posted: 21 Nov 2017 03:47 AM PST Reference: Hein, Andreas M., et al. "Project Lyra: Sending a Spacecraft to 1I/'Oumuamua (former A/2017 U1), the Interstellar Asteroid." arXiv preprint arXiv:1711.03155 (2017). And, to keep everybody's hopes up, allow me to highlight the following quote: "It is concluded that although reaching the object is challenging, there seem to be viable options based on current and near term technology." Can we get on board of this? Special shoutout to Redditors from JPL, ESA and other space agencies .... Any ideas? submitted by /u/Gargatua13013 [link] [comments]

Why does the infinite series 1/n diverge? Posted: 21 Nov 2017 05:05 AM PST I get that the integral of 1/x is ln(x) and ln(x) increases with x to infinity, but 1/n also approaches 0 as n approaches infinity. Shouldn't the series converge if we're eventually just going to be adding 0 to it? submitted by /u/imokayatmath [link] [comments]

How fast does a pressurized gas move to a lower pressure area? Posted: 21 Nov 2017 12:47 AM PST I remember being told that the pressure wave velocity is limited to the speed of sound in that medium at whatever temperature it is at. So if you had two tanks (A and B) joined by a pipe with a valve, tank A is pressurized and tank B is at atmospheric pressure. The valve is then instantly opened. Is the velocity of the gas in the pipe just proportional to the pressure differential between the two tanks? Or is there some sort of choked flow condition that occurs? The reason for the question is that I just watched an episode of MythBusters where they were able to accelerate a ping-pong ball to 1100mph, which is much faster than the speed of sound. I wasn't aware that this was possible. submitted by /u/BearInTheCorner [link] [comments]

How does Facebook Messenger encryption work? Posted: 21 Nov 2017 05:46 AM PST As I understand is, the 'secret message' feature uses a key to encrypt the data on your end, it's transmitted while encrypted, and then at the other end it's decrypted using the same key. (A key I assume being a kind of code which scrambles the message into nonsense and can be reverse-engineered to make it a message again). What I'm really wondering is: how does the key get transmitted between the two accounts securely? Wouldn't someone who intercepted the encrypted message just as easily intercept the key, assuming that the two accounts have to communicate the key to each other? submitted by /u/Ge0rgeBr0ughton [link] [comments]

Is Gravity Weaker in the Center of a Stellar Body? Posted: 20 Nov 2017 09:23 PM PST As you go closer to the center of an object, you would think that the gravity would actually weaken due to the mass of the object that you have already passed.. Imagine you made it to the core of the earth. The gravity would be pulling you from all sides rather than smashing you. The pressure may not be that great either considering this effect. I'm not saying that this idea is correct, but if it makes sense, then nuclear fusion wouldn't happen at the core of a star. It would happen in a sphere ring say 1/3 of the way towards the core. submitted by /u/WantToBeMartian [link] [comments]

How was it discovered that same metals would stick together in void? (plus a couple of questions in comments) Posted: 21 Nov 2017 01:49 AM PST and how it that they keep their shape in space? and how is it that spaceships and the ISS parts are not sticking together. how are repairing done, using tools with different metal composition? is there any metal on spacesuits? could they get attached to something? when releasing satellites and stuff in space, how is it that the mechanical arm is able to move and twist and expand and come into a smaller packed size and the metals are not sticking to one another (if that makes sense)?

Do changes in the Earth's rotation influence earthquakes?

Why did the Apollo CSM not have solar panels? Posted: 19 Nov 2017 10:51 PM PST The Soyuz Craft have always had solar panels, even today, yet the Apollo, Gemini, Mercury and Space Shuttle Orbiter, which did things similar to Soyuz (rendezvous and long duration docking) used only fuel cells. submitted by /u/0x4f0x770x610x690x73 [link] [comments]

Why are solar-powered turbines engines not used residentially instead of solar panels? Posted: 20 Nov 2017 05:00 AM PST I understand why solar-powered stirling engines are not used in the power station size, but why aren't solar-powered turbines used in homes? The concept of using the sun to build up pressure and turn something with enough mechanical work to turn a motor seems pretty simple. So why aren't these seemingly simple devices used in homes? Even though a solar-powered stirling engine has limitations, it could technically work too, right? I apologize for my question format.

Could the volume inside a black hole's Schwarzschild radius be infinite? Posted: 19 Nov 2017 08:19 AM PST To keep things imaginable, picture a black hole in 2 dimensions (the ball-rubber sheet view). As the ball becomes denser, the well in the rubber sheet deepens. At infinite density, we should reach an asymptote in which the well is infinitely deep. Now, consider Gabriel's horn. To construct this, plot y = 1/x from x=1 to infinity and rotate it around the x-axis, resulting in this. While having a finite volume, it's surface area is infinite. What I'm wondering is, does this translate to black hole physics at all? Back to the rubber sheet model, could a black hole create an infinite surface area (on the rubber sheet) along the same lines of thinking? As we go from 2D to 3D area becomes volume, so could the volume be infinite? submitted by /u/Shattered_Sanity [link] [comments]

Can someone explain me the basis of a quantum gate? (quantum computing) Posted: 20 Nov 2017 02:58 AM PST Hello so i just tried to understand the basis of the basis. I know only few people work on that so my luck are small to find here. Anyway a lot of folks are interested in the subject so maybe one of you know. I understand how work a logic gate (binary), also a transistor, a full adder. I would like to get how the things are done, i mean not really all the complicated things just the principe but a bit more in depth that explaining "there is an other state between 0 and 1 and this give power".. Maybe an example of what happen, we put what in order to create a quantum logic gate, like some electrons, some material, and how the maths work for the simplest quantic gate, like for example maybe what we can make in addition of NOT XOR etc, and how we make it or the principles of it. thanks quantic people submitted by /u/camaronmars [link] [comments]

Colleague did a Cluster Analysis. But what do the clusters "mean"? Posted: 20 Nov 2017 05:00 AM PST I've been asked to review a paper by a new post-doc on weather records (snow cover) for the country, and how it has changed (decreased, of course!) over the years. Part of the paper is a cluster analysis of about 100 weather stations' snowfall records. He used some stat software and grouped them into 6~8 clusters. My question is, "Well, what do these clusters mean? What do they represent? Is one cluster snow totals in high mountain elevations and another cluster snow totals near lakes?" To which the post-doc (who has never impressed me with his science fundamentals, but he is more literate than me on this topic because he is writing a paper on it...god, I hope he is more literate than me) basically replied, "Doesn't matter, they're clusters and that's what the cluster analysis program output says. You should read up about cluster analysis." I am about as (il)literate in cluster analysis as a 1-hour Wikipedia dive and a few papers can make. But I have a gut feeling that cluster analysis just to make clusters with no meaning is about as senseless as finding Jesus in pieces of toast. That the cluster analysis may be completely mathematically sound, but if there is no explanation as to what the clusters actually represent, the only value is that they might represent some pattern that will be revealed later? Or that they represent some pattern that can be useful even if the underlying meaning is not known..yet some inkling as to what the pattern might be would help more than just "These 5 data points in the set of 100 seem to be a similar enough to be a cluster when analyzed at this level." So, apart from the obvious that I need to keep studying, is my instinct wrong? Do clusters without a "story" nor even a glimmer of a "story" actually have any practical use? And even if there is no practical use, is that still "good enough" for publication (in that maybe someone else will figure out the pattern of the clusters)? submitted by /u/jade_crayon [link] [comments]

What determines the distribution of energy between an electron and a neutrino in Beta Decay? Posted: 19 Nov 2017 12:43 PM PST I am studying Physics and as part of the course I have to know that the energy of Beta particles varies up to a maximum due to the emission of a neutrino as well.

Imagine I detect (localize) a particle at one location, and wait a short period of time to let its probablility distribution "spread out". Does this probability go to zero at some finite distance away, based on how long I wait? Posted: 19 Nov 2017 08:37 PM PST I just saw a question like "what is the probability that an electron from the other side of the Earth is in my room. This made me wonder. AFAIK, an electron's probability distribution in space extends infinitely, but with an exponential decrease the further out you go. Does this not mean that an electron prepared in some localized state has a non-zero probability of traveling faster than the speed of light? The only way around this is if the probability distribution in space went to zero at some finite distance away, that is related to the amount of time it's been since the electron was localized earlier. This distance being c*t. Is this right? Is this idea explained anywhere? submitted by /u/FerrousBuchner [link] [comments]

How did a population of landlocked seals manage to establish itself in lake Baikal, of all places, at an altitude of 450 m and several hundred kilometers from the Nearest coastline??? Posted: 18 Nov 2017 06:04 PM PST I'm familiar with other landlocked seal populations, such as those in Lac des Loups marins in northern Québec, but those are right next to the coast and roughly at sea-level too .... easily explained by isostatic rebound. But Baikal??? The Baikal critters are perched way up at almost half a km altitude and almost 1500 km from the closest coast (the Okhotsk sea). I don't get it... And if it happened in Baikal, why not in other large freshwater lakes such as lake Superior, Great Bear lake or even lake Ladoga? EDIT: thanks to /u/Gsdthrowaway1 for bringing the lake Ladoga seals to my attention. But these are still landlocked seals in a place that makes sense : a low-lying lake in a flat area prone to isostatic rebound within spitting distance of the sea. submitted by /u/Gargatua13013 [link] [comments]

Why do we assume the core of a black hole has a singularity in it? Posted: 19 Nov 2017 03:05 AM PST How does it make sense that something can be infinitely dense, i.e. have 0 volume? I could understand it if a black hole was an object of finite but extreme density—then its escape velocity would still be stronger than the speed of light, but the laws of physics would still make sense at the core because space would not have infinite curvature there. But why do people say black holes have INFINITE density? submitted by /u/untameableimpala [link] [comments]

What's wrong with the original definition of the gram? Posted: 19 Nov 2017 02:09 AM PST According to Wikipedia, the gram was originally defined as the mass of a cubic centimeter of water, and then later redefined as one thousandth of the mass of a particular metallic object. I've heard this was due to the isotopes in water causing minute variations, but we have since become much more adept at measuring isotopic differences, and presently use water to define our temperature scales. Are there additional concerns preventing us from simply reverting to the original definition? submitted by /u/algorithm1248 [link] [comments]

How can a real particle have negative energy? Posted: 18 Nov 2017 07:46 PM PST Hi, I'm reading Stephen Hawkin's "Brief history of time". There's a chapter where he talks about black holes and I assume is the precursor to hawking radiation, but basically it explains that at the event horizon there are particle-antiparticle pairs being created, some escape into space (particles as radiation, antiparticles annihilate pretty soon after their escape), but whenever a particle falls into the black hole it reduces it's mass (instead of increasing it). Hawkins says "Normally, the energy of the particle is still positive, but the gravitational field inside a black hole is so strong that even a real particle can have negative energy there". Cans someone elaborate on this? how is the possible? I mean to me it just sounds like "well, it has to be negative or else the black hole will grow, so lets just make it so" but doesn't really click (in my head) submitted by /u/Nghtmare-Moon [link] [comments]

What's the difference between soap and detergent? Posted: 18 Nov 2017 08:15 PM PST I've often heard that many modern "soaps" are not really soap, but detergent. But, what's the actual difference?

Will a tank full of water weigh the same if you add a whale to the same tank? Posted: 18 Nov 2017 08:32 PM PST Hello people of the internet.

I say the tank will get much heavier assuming that the water does not overflow from the addition of the whale, but I am not sure it will reflect the exact weight of the whale. My wife on the other hand believes the tank will either stay the same weight or become a little heavier since things are almost weightless in the water.
