What is loop quantum gravity and how does it differ from String Theory? Posted: 18 Sep 2016 11:12 PM PDT I'm only in my sophomore year in high school, and they don't teach particle physics here at my school. I've read some books on String Theory, but recently I came across "loop quantum gravity" and I don't really understand what it is. submitted by /u/notam0derator [link] [comments]

How does Quantum Tunneling help create thermonuclear fusions in the core of the Sun? Posted: 19 Sep 2016 05:57 AM PDT I was listening to a lecture by Neil deGrasse Tyson where he mentioned that it is not hot enough inside the sun (10 million degrees) to fuse the nucleons together. How do the nucleons tunnel and create the fusions? Thanks. submitted by /u/mistymountainz [link] [comments]

What happens to fat cells as fat is metabolized? Posted: 18 Sep 2016 07:42 AM PDT Is fat metabolism basically just a point in time process, or does it kick off a process of longer changes to the fat cells? What is that process and how long does it take? This question comes from a thought I had on a 6 hour bike ride yesterday. submitted by /u/2-4-decadienal5 [link] [comments]

What makes supernovas "explode"? Posted: 18 Sep 2016 08:55 PM PDT Hello AskSciencers! My question is: What makes supernovas explode? I understand the general process after the star stops fusing hydrogen (it starts to fuse heavier elements, like helium). When the nuclear fusion starts producing Iron, which ruins the star's hydrostatic equilibrium and gravity becomes the major force at work. At this point is what I want to know: When the star collapses due to lack of the hydrostatic equlibrium, what makes it explode? submitted by /u/r-olivaw [link] [comments]

If flamingos were to go extinct today, would their remains have any indication that they were bright pink? Posted: 18 Sep 2016 03:43 PM PDT I went to a science and history museum today and we were checking out the dinosaur exhibit. A few of the things I saw said that basically we're not 100% sure on dinosaurs, especially their skin colors. So that got me thinking about animals today. Flamingos are pink for apparently no reason, and if nuclear holocaust happens today and we lose all of our records, would there be any way for future scientific researchers to know flamingos were pink? submitted by /u/CherrySlurpee [link] [comments]

Why do plants turn brown as they die? Posted: 18 Sep 2016 07:19 PM PDT I understand that they're usually green because of chlorophyll, but what happens to the chlorophyll that changes the plant's color? submitted by /u/TheHodag [link] [comments]

How do the heart's autorhythmic fibers work? Posted: 18 Sep 2016 01:54 PM PDT The heart has these autorhythmic fibers that are self-excitable. Can you explain how the action potentials work, where and how they are generated, and how these fibers are involved in arrhythmias? Also, how do these cells become so specialized during embryonic development? My A+P (university Med classes -woohoo!) textbook says that about 1% of the cardiac muscle fibers actually become autorhythmic. How do those 1% know when to begin their job? Sorry for all the questions. The human body is insanely intricate. Feel free to pick only one of the questions to answer. Thanks for your input! submitted by /u/SliceofSeoul [link] [comments]

When I cook bacon (100 calories) and drain the grease (1-2 Tbsp), the bacon is now 100-x calories, where x is the calories of the grease, correct? Posted: 18 Sep 2016 04:54 PM PDT I'm trying to count my caloric intake as closely as possible, and wanted some verification regarding my question because I can find calories in bacon on the package and bacon grease calories on the web. The packaging I assume states the bacon calories along with its fat, but when cooked down, I assume it loses a hefty amount of those calories. submitted by /u/rgupta1919 [link] [comments]

Are flu bouts contracted from the vaccine transmissable? Posted: 18 Sep 2016 06:20 PM PDT To expand - if I get flu symptoms from the vaccine, will it still be contagious? Or will I only have the symptoms without necessarily having the same infectiousness. submitted by /u/SensibleParty [link] [comments]

How do photons (when emitted from a source) decide which direction to go? Posted: 18 Sep 2016 09:55 AM PDT Many chemical processes emit a photon when they release energy. How does an individual photon from a source decide which direction to go? submitted by /u/GeorgePukas [link] [comments]

How did we prove heliocentrism? Posted: 18 Sep 2016 05:27 PM PDT I know the earth and the other planets revolve around the Sun but how did we prove it? I'm assuming it's because we know that smaller gravities attract (are acted upon) by larger gravities but I'm not sure that's the sole reason we know or not submitted by /u/LakersFan34 [link] [comments]

How does a computer know that a number is negative using the 2's complement method? Posted: 18 Sep 2016 04:55 PM PDT For example how does a computer know that 10010010 is -110 in base 10 and not 146 in base 10? submitted by /u/miercat [link] [comments]

Why when zoomed in upon, do individual characters on a screen have blurry edges? Posted: 18 Sep 2016 04:49 PM PDT Why is it that when a character on a screen is zoomed in upon that it is not that the letter is 100% black and the rest of the screen is 100% white, but instead there are some pixels between the character and blank space which are either a grey, blue, orange or other colour? I would have thought characters would be crisper looking if there were no gradient between the actual letter and the rest of the page. Is this a limitation of them being vectors? Thanks submitted by /u/pixeljuice_ [link] [comments]

Do people who eat fewer calories live longer? Posted: 17 Sep 2016 02:52 PM PDT I swear I remember reading somewhere that people who are fewer calories tended to have longer lifespans, and for that reason I've tried to eat a little less (not going for a second serving, etc.). Obviously people who are overweight are less healthy than people of average weight, but does the trend continue in the opposite direction, with people who are lighter than average or eat slightly less than average living longer? Recently I thought about it and realized I don't have any idea where the original idea/assumption came from. Is there any basis in science? submitted by /u/yaminokaabii [link] [comments]

Why do matter and anti-matter annihilate each other when coming into contact? Posted: 17 Sep 2016 12:04 PM PDT I was thinking about how a neutron can decay into a proton and electron (plus something else, I think?) - two particles of opposite charge. So how come an electron and an anti-electron (positron?) wouldn't somehow combine into some neutral particle rather than self annihilate and convert their energy to photons? submitted by /u/dougman82 [link] [comments]

What happened to Olestra? Posted: 17 Sep 2016 03:38 PM PDT I understand that it caused negative gastrointestinal effects but can someone explain the science behind it? Is it still legal in North America? submitted by /u/PotMeister [link] [comments]

(Biology) How would you die from cancer as opposed to chemo? Posted: 17 Sep 2016 02:28 PM PDT Maybe I shouldn't be asking this here but how do you die of cancer/what does it feel like opposed to chemo ? So I know how cancer is caused, what it does and how it spreads through the body, but since everyone gets chemo which kills the cells (hopefully the cancerous ones first) a lot of times the body doesn't recover after the cancer is gone because the radiation kills them. Obviously I'm not talking about successful cases of remission, purely cases of death, I want to know the difference biologically and 'how it feels' between dying of chemo but mostly cancer free and dying of cancer having chose no forms of medication. Edit - ahh right thanks guys, this was really informative. So it doesn't really kill you itself, but by (putting it basically) shutting down the systems it's located in (can also cause wasting, explained by /u/iayork ), I know it's not the be all and end all though as it can spread to the lymphnodes. Also /u/Kurgon999 yes I did actually think chemo was directed radiation so no problem, it's not a laser and doesn't cut you so I didn't give it much thought but it seems I was wrong. submitted by /u/The_Meatyboosh [link] [comments]

Are O(2^n) and 2^O(n) the same classes? Posted: 17 Sep 2016 03:27 PM PDT In computer science and math, in order to describe functions bounded from above from the function 2n, some authors use the first notation, some others use the latter. Is there a difference between these class of functions? submitted by /u/a-lumen [link] [comments]

Would reducing the frame rate of the part of a computer screen that's inert while increasing the part of the screen that's active save power? Posted: 17 Sep 2016 03:20 PM PDT From what I understand, GPUs save power by reducing the frame rate of a screen when there is less motion on the screen. But they do this for the entire screen at once. Would a GPU that only reduces the frame rate of part of the screen he efficient? Would it even be possible or would you need a separate controller for each pixel? submitted by /u/lookmanofilter [link] [comments]

Are alpha particles in and of themselves radioactive? Posted: 17 Sep 2016 12:17 PM PDT That is to say, if an alpha particle has already been ejected from the parent isotope, is that particle itself radioactive? If it is, does it have a half life? I think I answered my question already by googling He-4, which is stable. So it's just the speed of the particle and lack of electrons that causes the ionization, right? submitted by /u/shitheadsean2 [link] [comments]

Do black holes accelerate matter to light speed? Posted: 17 Sep 2016 01:58 PM PDT Does matter ever become gravitationally accelerated to c? submitted by /u/bilabrin [link] [comments]

Why is diffusion of hard spheres not affected by the density of the spheres? Posted: 17 Sep 2016 08:52 AM PDT I know that: frictional coefficient = 6*pi*viscosity*Stokes radius and that frictional coefficient is inversely proportional to diffusion coefficient. Stokes radius is the radius of the sphere (as the sphere is hard). Molar flux is the product of the diffusion coefficient and the concentration gradient, so it is the radius of the sphere that is related to it's diffusion, not the mass (as density & mass don't come into any of the equations). But if I think intuitively, the spheres are being bombarded by other particles as they move through the medium. If a sphere is more dense, the bombardments would transfer the same momentum but less speed, and the sphere would move more slowly. If a particle is slowly wiggling through solution, a heavier particle would have smaller 'wiggles' and move more slowly. I have to be wrong somewhere, but where? submitted by /u/994phij [link] [comments]

[Biology] There's a dinosaur called Carnotosaurus, whose arms end after the elbow, what are the benefits of this? Posted: 17 Sep 2016 01:31 PM PDT Also, why does it even have arms, do those "stumps" serve a purpose, are they for balance? Is this the case of a mutation and not really just natural selection? Why do we not see more animals with this feature? submitted by /u/Tsunami6866 [link] [comments]

How do you calculate displacement, velocity, and proper time of an object undergoing constant proper acceleration, starting from non-zero, non-collinear velocity with respect to an observer? Posted: 17 Sep 2016 03:36 PM PDT Using the Relativistic Rocket equations, the displacement d, velocity v, and proper time T of an object undergoing proper acceleration a from rest for a given coordinate duration t can be calculated with: d = (c2 /a) (sqrt[ 1 + (at/c)2 ] − 1) v = at / sqrt[ 1 + (at/c)2 ] T = (c/a) ch−1 [ad/c2 + 1] Imagine an object starts with initial relativistic velocity v0, and accelerates with proper acceleration a at some non-zero angle θ from v0. How would I calculate the object's displacement, velocity, and proper time after a given coordinate duration? submitted by /u/taylorules [link] [comments]

How does T-cell know when to stop its immune response? Posted: 17 Sep 2016 04:27 AM PDT I mean, TCR has ITAM domains and inhibitory receptors have ITIM domains. Their both ligands are on APCs (I suppose). If a t cell recognizes a non-self antigen, it will receive both inhibitory and activatory signals. 1) How does t cell know what to do (there is a perfect balance between stimolatory and inhibitory signals)? 2) When t cell begins an immune response, how does it know when to stop this response, in order to not damage your organism? submitted by /u/Biasy [link] [comments]

Do bioluminescent/biofluorescent organisms use sunlight to recharge, or is it primarily an enzyme based reaction? Posted: 17 Sep 2016 06:17 AM PDT The main reason I'm asking this is because on my campus there is a river with these luminescent jellyfish, however I have noticed that they don't light up in the day or on nights where the moon-light is especially bright. There are also what appear to be thousands of luminescent plankton in the river, and during these times they too do not light up. submitted by /u/TheDesertSnowman [link] [comments]

At what size does a wire mesh stop acting as a Faraday cage? Posted: 16 Sep 2016 06:27 PM PDT Wire meshes can often be used as Faraday cages to shield the inside from exterior electromagnetic waves.

what is the definition of the word "cold" in deep space? Posted: 16 Sep 2016 06:30 PM PDT if cold is the slowing of the vibration of atoms and there are only sparse atoms in some areas of space, how is "cold" expressed where there are so few atoms? submitted by /u/TheQuips [link] [comments]

Is there a way to determine the direction of gravitational pull on the surface of an irregular object? Posted: 17 Sep 2016 07:08 AM PDT Let's say we had a 1000km-thick cereal bowl floating in space. If I started pouring milk onto/into this bowl at any given point (so, not necessarily into the bowl - perhaps on the outer side or bottom), would we be able to determine where the milk would flow? If so, how? My understanding of gravity starts and stops at spherical objects, which is why I'm curious. If we wanted to land a probe on an asteroid shaped like, say, a cereal bowl or a donut, how would we know the best spot to land? submitted by /u/dobu [link] [comments]

Is there such a thing as a core of a star? Posted: 16 Sep 2016 03:44 PM PDT I know hydrogen becomes iron, but does that iron amass in the center of the star to eventually cause the star to fail, either in nova or in red dwarf? submitted by /u/rugbyrun [link] [comments]

How would Nuclear Propulsion work? Posted: 16 Sep 2016 03:58 PM PDT I want to know how it would work. But most of all, how it could successfully be done without damaging the ship. Also would it be in space or on the ground? submitted by /u/ArmoredBattalion [link] [comments]

Could Mars have had a rich, earth-like flora even when we now can't see any hint of it? Posted: 16 Sep 2016 01:21 PM PDT When we talk about life on Mars we usually talk about microbes or other simple and small life forms. I wonder if there could once have been plant life, forests with huge trees without seeing any evidence today. Like, could they have been completey destroyed after Mars lost its atmosphere? So that not a single tree trunk or something like that survived (as a fossil) ouf of billions of trees all around the planet? Because all we see on pictures from our satellites and rovers today is basically wasteland. Or is the lack of any evidence today a strong hint that if there ever was life on mars, it never was much more developed than microbes. submitted by /u/linknewtab [link] [comments]

What is going on in your body when it starts to hurt after resting on a hard surface for a long time? Posted: 16 Sep 2016 01:20 PM PDT I have been transitioning to sleeping on the floor this past week and although it is not at all necessary to exclude a folded towel beneath my head I would really prefer not to have to do that. Problem is, as you might expect, trying to fall asleep with your head resting on a hard carpeted floor for thirty minutes results in a progressively more irritating pain at the point of contact the longer I refuse to lift it up. What is going on at that part of my head that causes it to hurt that way? Are there going to be any significant consequences to ignoring it? A callus? Reduced blood-flow to my brain while I sleep? I don't really know, so I'm asking science. submitted by /u/SixtyNinePlatypi [link] [comments]

What is implicit egotism and how much does it really affect our lives? Posted: 16 Sep 2016 04:22 PM PDT I read this article today about how people are drawn to things that are similar to their name.

Are there any known weaknesses in the Nielsen Ratings? Posted: 16 Sep 2016 03:19 PM PDT From what I understand they sample cities around the country and estimate viewing based on those samples. Are there any biases or things unconsidered by this method of data collection? I was also curious if perhaps somebody cross referenced data from Netflix viewings. I'm guessing Netflix uses more direct data (i.e. simply how many people streamed this show or movie) and maybe you could compare patterns in viewing of shows or genres by this precise data set and see if there are any interesting discrepancies between the two. The second part makes this a loaded question, but answers on either or would be great! submitted by /u/acollich [link] [comments]
