does everything emit gravitational waves? Posted: 13 Feb 2016 05:52 PM PST hello I did a lot of googling and there seems to be a lot of confusion regarding the new discovery, in one paper i read that only accelerating things emit gravitational waves, in the other i read that only moving objects do. If only moving objects do, moving compared to what?? Could anyone explain how does this work exactly? Another question: they are waves, so they should have frequencies and amplitudes? how do those values get determined exactly? submitted by /u/Ricike [link] [comments]

Do g-waves attenuate with time(or when they interact with matter)? Posted: 13 Feb 2016 09:14 PM PST If they do attenuate, how can we determine the source considering the waves could have interacted with a random number of matter submitted by /u/ArunB92 [link] [comments]

How does the 'security pattern' in the Canadian polymer bills work? Posted: 13 Feb 2016 06:28 PM PST Short description of what I'm talking about: In 2011, the Bank of Canada started issuing the Frontier Series of Canadian banknotes, which were the first to be produced on polymer. If you look through the circle in the middle of the frosted maple leaf, there is kind of a 'display' of the denomination of the bill. How does this work? Specifically, why can't I see it on the actual bill (i.e. in the reflection of the circle), and why does it stay centred on the point of light? For that matter, why does it only work with a small light source anyways?

Is a measurement of Planck time arbitrary in time? Posted: 13 Feb 2016 05:15 PM PST Does a measurement of Planck time have to occur during a discrete period/cycle (i.e. clock cycle), or can it be measured during any arbitrary period along an infinite timeline? And if time is not infinite, does this then impose a universe "clock cycle"? submitted by /u/cradle_slayer [link] [comments]

How close to GW150914 (the black hole merger) would I have to be to feel the gravitational waves on my body? Posted: 13 Feb 2016 02:15 PM PST I asked this question in the megathread, but it was buried, so I'm trying again here. How close would I have to be to the GW150914 event (the black hole merger) to feel the effect of the gravitational waves on my body? submitted by /u/andrerav [link] [comments]

Given the extreme difficulty of unifying Gravity with the other three fundamental forces is it not likely that it's just a completely unrelated phenomenon? Posted: 13 Feb 2016 03:16 PM PST As I understand it gravity is a fairly stable deformation of spacetime (or, possibly the cause of the deformation, I'm unclear on the specifics), while the other three forces have no similar effect. In fact it seems to behave completely differently from the others, and to me this suggests it isn't similar enough to be unified (seems like suggesting that a rope and a phone call are similar because they can, given the right circumstances, be used to move an object closer to me). Why, then, is there such a strong desire within the physics community to unify them? Or (and I consider this far more likely, given my relative ignorance on the subject compared to actual physics researchers) am I completely missing something? submitted by /u/StarkRG [link] [comments]

Are the LIGO detectors susceptible to seismic activity? Posted: 13 Feb 2016 02:18 PM PST Saw this gif of how the LIGO detectors worked to determine gravitational waves and it got me thinking, if the two detectors are separated by a large distance (in this case Louisiana and Washington), and are trying to measure perturbations smaller than a proton, couldn't seismic activity confound the data? submitted by /u/anubis_of_q [link] [comments]

Why does atmosphere thickness (and ground pressure) does not depend solely on planet's surface gravity ? Posted: 13 Feb 2016 02:35 PM PST Venus has a lower surface gravity than Earth, yet its atmospheric pressure is much bigger ... Has this something to do with atmosphere composition ? Bonus question : With the same composition, would atmospheric pressure be then only dependent on planet gravity ? Thanks submitted by /u/Omfraax [link] [comments]

Why does Oklahoma have so many earthquakes when it's not on a fault line? Posted: 13 Feb 2016 09:51 AM PST Many of the links I found were just talking about fracking causing them, but these quakes have happened long before fracking and it doesn't make sense to me. submitted by /u/flobbus [link] [comments]

Why are long radioactive half-lives bad when talking about waste from nuclear power generation? Doesn't a long half life mean there is less radioactivity? Posted: 13 Feb 2016 12:38 PM PST When reading news about long term storage of nuclear waste I get the impression that a long half life is much worse than a shorter half life. I get that a very short half life is good. If it has a half life of hours or days it is easy to contain until it is no longer radioactive. But when we are talking about hundreds of years compared with hundreds of thousands of years, both are essentially gonna be around "forever" from a human perspective. Then it seems like 1000x less radiation might be better. submitted by /u/almost_useless [link] [comments]

AskScience AMA Series: I'm Thomas Hurting, we make tiny human brains out of skin cells, modeling brain development to help research treatments for diseases like Parkinson’s, Alzheimer’s or Multiples Sclerosis, and to help develop personalized medicine. Ask me anything! Posted: 13 Feb 2016 04:34 AM PST Hi Reddit, Making your skin cells think – researchers create mini-brains from donated skin cells. It sounds like science fiction, but ten years ago Shinya Yamanaka's lab in Kyoto, Japan, showed how to make stem cells from small skin donations. Now my team at Johns Hopkins University is making little brains from them, modeling the first two to three months of brain development. These cell balls are very versatile – we can study the effects of drugs or chemicals. This promises treatments for diseases like Parkinson's, Alzheimer or Multiples Sclerosis. But also the disturbance of brain development, for example leading to autism, can be studied. And we can create these mini-brains probably from anybody. This opens up possibilities for personalized medicine. Cells from somebody with the genetic background contributing to any of these diseases can be invaluable to test the drugs of the future. Take autism – we know that neither genetics nor exposure to chemicals alone leads to the disease. Perhaps we can finally unravel this with mini-brains from the skin of autistic children? They bring the genetic background – the researchers bring the chemicals to test. And the mini-brains are actually thinking. They fire electrical impulses and communicate via their normal networks, the axons and neurites. The size of a fly eye, they are just nicely visible. Most of the different brain cell types are present, not only various types of neurons. This is opening up for a more human-relevant research to study diseases and test substances We've started to study viral infections, but stroke, trauma and brain cancer are now obvious areas of use. We want to make available mini-brains by back-order and delivered within days by parcel service. Nobody should have an excuse to still use the old animal models. And the future? Customized brains for drug research – such as brains from Parkinson patients to test new Parkinson drugs. Effects of illicit drugs on the brain. Effects of flavors added to e-cigarettes? Screening to find chemical threat agents to develop countermeasures for terroristic attacks. Disease models for infections. The list is long. And the ultimate vision? A human-on-chip combining different mini-organs to study the interactions of the human body. Far away? Models with up to ten organs are actually already on the way. This AMA is facilitated by the American Association for the Advancement of Science (AAAS) as part of their Annual Meeting Thomas Hartung, director of the Center for Alternatives to Animal Testing, Johns Hopkins University Bloomburg School of Public Health, Baltimore, MD.

Is there any evidence that dogs behave differently around human infants compared to around human adults? Posted: 12 Feb 2016 05:55 PM PST I often hear anecdotes of dogs acting more gently or protectively around babies/infants, but I wonder how much of this is just anthopomorphizing.

Why aren't local anaesthetics used for all surgery? Posted: 13 Feb 2016 06:34 AM PST After all, it's far safer, and doesn't involve putting somebody into a coma. I mean, local anaesthetic is used for some major surgeries (I.e. Brain surgery), so why isn't it used for all surgeries? Even so, why can't a patient just request local anaesthesia if they're afraid of going under? submitted by /u/Blimtole [link] [comments]

Would firing a bullet in a highly polluted area (ex: Beijing) have different ballistics than if it were fired in a clear environment (ex: montana)? Posted: 12 Feb 2016 08:53 PM PST Specifically I am wondering if it would be more (or less) difficult to make extreme long range shots in a location that has high air pollution density. In addition, are there any factors other than just the PPM that would affect the ballistics of the round? submitted by /u/Hilamary [link] [comments]

Does the confirmation of gravitational waves contradict String Theory? Posted: 13 Feb 2016 02:24 AM PST So I'm new to reddit, but i don't know where to ask this. Since the discovery of gravitational waves has confirmed that Einstein was right: gravity is a property of Space-Time, as Space-Time is deformed by mass, thus giving objects their trajectory through space; does this mean that String Theory is wrong? I might have no understood String Theory right, but if i understand correctly, it, like some of the theories that are being tested at the LHC are looking for the graviton, the particle that transfers the force of gravity. To me it seems that these two theories are incompatible. I may be very wrong, since it's unlikely that I understood String Theory. Thank you. submitted by /u/Dughau [link] [comments]

Does light moving in a medium have a reference frame? Posted: 12 Feb 2016 02:09 PM PST I've heard that something moving at the speed of light doesn't have a reference frame. Does this mean when light is moving slower it suddenly has a reference frame? submitted by /u/Im_thatguy [link] [comments]

Does our brain use more calories if we are actively doing something mentally stimulating? Posted: 12 Feb 2016 01:17 PM PST If our brains use around 20% of our calories, is this a general flat rate the brain just uses, or if we're doing something like learning or problem solving does it require more calories? submitted by /u/graystripeblack [link] [comments]

Does gravity increase as mass increases? Posted: 13 Feb 2016 06:43 AM PST My son and I were discussing how you can never reach the speed of light because as you get closer to the speed of light you mass increases until you have almost infinite mass and it would take almost infinite energy to accelerate that mass to the actual speed of light. He wondered if there would be any harmful effects for a person going that fast and I wasn't sure how to answer. My first thought is that as you increase in mass, your own gravity would increase to the point that your bone and muscles could no longer support you and you would collapse into a gooey ball. Is there any truth to this? Does your own gravity increase as you increase velocity? submitted by /u/angels_fan [link] [comments]

Are we currently able to observe what a thought 'looks like' in the brain, i.e. see the exact path it takes between neurons?

Is the LIGO experiment using the same design/layout with Michaelson's and Morley's experiment? Posted: 13 Feb 2016 06:05 AM PST From what I have understood in both the LIGO and the Michaelson and Morley experiments a light beam is splitted and let run across some km. Then it is combined through the same prism and the energy change is measured through symbolometry. This energy change is caused because one of the two beams runs quickier. The only difference I can see is the size (LIGO is some km long amd M&M built it within an library) and most importantly that in LIGO one of the beams runs faster because of the space-time distortion (caused by the Gravitational waves) while in the Michaelson's and Morley's experiment the speed change is caused by the fact that one of the beams is running through the aether amd being affected by the earth's movement. I am not trying by any means to demote the importance of this discovery or the LIGO team. What they found is astonishing. I am just observing some similarities and asking for more info. Thanks! submitted by /u/cnpapado [link] [comments]

Speed of the gravitational wave detected? Posted: 12 Feb 2016 08:02 PM PST So the gravity wave that was just detected came from over 1 billion light years away, but does that mean it began its travel more than 1 billion years ago? How fast does a ripple in space time propagate? I know the speed of light is the universal speed limit, but does this phenomena follow that rule? submitted by /u/prkirby [link] [comments]

Put someone on bypass when a heart stops? Posted: 13 Feb 2016 03:57 AM PST So.. I was just wondering the other night, I'm sure there a lots of cases where a patients heart stop in a hospital during surgery/medical ward. I was wondering how often, after failed attempts of resuscitation, do they put a patient on bypass (blood pump of somekind - we have those,right?) Or would it take too much time to set up and the damage done would be irreversible? submitted by /u/Milchy [link] [comments]

[Physics]How do we really know speed affects time? Posted: 12 Feb 2016 01:42 PM PST I know that there was an atomic clock kept on the ground and they put an atomic clock in a plane and flew it around the world, and the clocks showed different times. Now I like to ponder the mysteries of the universe like a curious fellow I am. Now my question is, how did they arrive at the conclusion that speed affects time, when they used a device that counts the tiny vibrations of a cesium atom, which requires the movement of it. Now the reason I have this question is because if the speed of light is the fastest something can go, wouldn't the vibrations be reduced to zero? If the atom is moving at the speed of light, it wouldn't be able to vibrate in the direction of travel, thus giving a false positive right? I may be wrong here, or I am missing something stupid that slips my mind, I don't know. Can anyone here shed some light here? submitted by /u/Liveonafarm [link] [comments]

AskScience AMA Series: We study neutrinos made on earth and in space, hoping to discover brand-new particles and learn more about the mysteries of dark matter, dark radiation, and the evolution of the universe. Ask us anything! Posted: 12 Feb 2016 04:10 AM PST Neutrinos are one of the most exciting topics in particle physics—but also among the least understood. They are the most abundant particle of matter in the universe, but have vanishingly small masses and rarely cause a change in anything they pass through. They spontaneously change from one type to another as they travel, a phenomenon whose discovery was awarded the 2015 Nobel Prize for Physics. Their properties could hold the key to solving some of the greatest mysteries in physics, and scientists around the world are racing to pin them down. During a session at the AAAS Annual Meeting, scientists will discuss the hunt for a "sterile" neutrino beyond the three types that are known. The hunt is on using neutrinos from nuclear reactors, neutrinos from cosmic accelerators, and neutrinos from man-made particle accelerators such as the Fermilab complex in Batavia, Ill. Finding this long-theorized particle could shed light on the existence of mysterious dark matter and dark radiation and how they affect the formation of the cosmos, and show us where gaps exist in our current understanding of the particles and forces that compose our world.

Can a substance at 0K conduct heat? Posted: 12 Feb 2016 04:21 AM PST Conduction of heat is purely due to the collision & diffusion of molecules inside a solid, liquid or gas. Therefore if a substance was cooled to absolute zero (so all of its molecules are stationary) and was entirely enveloped by another single substance, does radiation allow it to warm up again?, or does it just stay on its own at that temperature indefinitely? submitted by /u/TheIntrepidGentleman [link] [comments]

What are the risks of introducing backdoors into a cryptographic function? Can you secure said backdoor with another unique function? Posted: 11 Feb 2016 04:52 PM PST Politics aside, I am curious why even put backdoors into a standard function if it allows an adversarial system to have an attack vector. Rather than attacking the function, why not just attack the backdoor? I could see securing the backdoor cryptographically, but would that allow the adversary to see any unique about the given hash? Meaning, will they see that there is a part of the function that is unique to the rest of the hashed string? What risk does a state posses when they introduce a backdoor into their encryption standards/functions? submitted by /u/myhuskyfriend [link] [comments]

If a fly flying directly down a train track is hit by an oncoming train, does the fly stop before changing direction, if so, for that moment is the train also stationary? Posted: 12 Feb 2016 05:58 AM PST This has been a debate in our office for some time, and none of us can provide a decent enough answer, with science to back it up. We've also been unable to find a similar enough question on-line. If a fly is hit flying directly towards a train does it have to come to a total stop before the force of the train carries it back in the opposite direction. If the fly is stationary before changing direction, for any period of time, the train would also have to be stationary for the same length of time which is obviously not possible. The alternative is that the fly never stops, but if the fly never stops, how does it change direction? Can someone explain which, if any is true and why? Some points for clarity.

Why do new comets miss the sun? Posted: 11 Feb 2016 03:28 PM PST A lump of rock out in the Ort cloud gets bumped, and the unrelenting pull of the sun's gravity draws it in. After 10s of billions of miles of the sun trying to score a bullseye, how is it some actually miss and become a comet? submitted by /u/Rmasterson1962 [link] [comments]

Is it possible to create a magnet so strong that it collapses into a black hole? Posted: 11 Feb 2016 04:02 PM PST From what I understand, black holes form when small densities cause the gravitational force to overcome the forces keeping atoms and/or subatomic particles apart. Would it be possible to do the same thing but swap gravitational force for the electromagnetic force? Perhaps with an extremely powerful electromagnet? If it is possible, what would it take? submitted by /u/Mr_Dr_Prof_Derp [link] [comments]

Because everything is constantly moving in space, and in enough time will every planet and star eventually collide making one giant star or planet? Posted: 11 Feb 2016 04:23 PM PST submitted by /u/Klassix [link] [comments]

Why do toddlers like to give stuff to people? Posted: 10 Feb 2016 12:59 PM PST I'm trying to find something on Google but all that comes up is about spoiling kids and how sharing is good. Just about every small person I've met and played with always gives me things, whether it's toys, food, or random objects. They come up and say, "here, have this. And this. And this. And this." My friend sent me a video a few minutes ago of the little girl she nannies handing her all of her blocks in handfuls. It's the sweetest thing in the world to experience, but I'm stuck as to why they do it. Has this been studied at all? submitted by /u/wigwam2323 [link] [comments]

Does the divots on dice change the probability of numbers being rolled? Posted: 10 Feb 2016 11:45 AM PST Since dice have 1-6 divots, shouldn't that mean that the side with 1 is heavier than the side with a 6? Shouldn't this cause the die to roll with the probability of 1 falling face down, thus rolling a 6 more common than 6 down and 1 up? submitted by /u/dlukz [link] [comments]
