| If heavier elements 'sink' towards the core of a star, why does fusion still occur there? Posted: 03 Mar 2018 04:05 AM PST Wouldn't the Hydrogen and Helium primarily used for fusion be in the outer layers, with the inner layers being mostly unfusionable elements? [link] [comments]  |
| Posted: 03 Mar 2018 04:08 AM PST How powerful is ice-albedo feedback? Does this tip us into a warmer world even if we bring CO₂ concentrations back to 350ppm(v)? Or is the warming from the total loss of the northern summer sea ice relatively small compared to direct (meaning before feedbacks) anthropogenic greenhouse warming? [link] [comments]  |
| Posted: 03 Mar 2018 07:04 AM PST Wouldn't microorganisms be able to evolve to use the resources available on the planet? For instance, a carbon rich planet could potentially have life forms that uses the carbon as their "oxygen". [link] [comments]  |
| Why does breath start to smell bad when people are hungry? Posted: 02 Mar 2018 10:11 AM PST Is it because the oral bacterial waste is building up or does it have something to do with the emptiness of the stomach? Why does eating make the bad smell go away? [link] [comments]  |
| Posted: 03 Mar 2018 05:14 AM PST Let's say that my field of view through the sight is about average. Now if I focus through my reflex sight with a 0.00000005 degree parallax angle to the axis of the barrel - then it may be possible for the target to be so far that it does not even come into my field of view - but the reticle will appear in the FOV nonetheless. Where the reticle exactly is should depend on the z-axis to the target, shouldn't it? [link] [comments]  |
| Could we start using older antibiotics again? Posted: 02 Mar 2018 10:17 PM PST The way some resistance works is by actively producing proteins, that's a disadvantage if the antibiotics aren't used. Will the mutation die out eventually, and how many antibiotics could this happen to? [link] [comments]  |
| Posted: 02 Mar 2018 09:17 AM PST Currently experiencing an unusually intense cold snap in the UK and local gritters are out spreading in force. But when the ice melts and the salt dissolves, won't this leave a lot of salt water flowing into the ground etc? [link] [comments]  |
| Are there any materials that are plasma at room temperature? Posted: 02 Mar 2018 02:39 PM PST If different materials, can have different melting or boiling points, that's should apply to plasma too, right? [link] [comments]  |
| Why doesn't ethanol from alcohol drunk react with the triglycerides in our blood? Posted: 02 Mar 2018 05:53 PM PST My understanding of biodiesel production is that triglycerides in vegetable oils or animal fats undergo transesterification when methanol or ethanol is added. If that's the case, then why doesn't ethanol from the alcohol that humans drink react in our bloodstream to form biodiesel? Is there simply not enough material? Or is it occurring on such a small scale that it is negligible? Or is my understanding just wrong? [link] [comments]  |

| Why aren’t galaxies spherical? Posted: 02 Mar 2018 02:11 PM PST I was following with much interest the news about S2 and its potential to provide more evidence (or potentially disprove) Einstein's Theory of General Relativity, and I got onto a tangent and ended up wondering, if every galaxy has a black hole in the middle, why do most galaxies (at least the conceptual images of galaxies) look like discs and not like spheres? A followup question would be why don't any of the planets follow an orbit pattern perpendicular to the rest of the "normal" orbits. This is my first post, so sorry for any violated rules!

| Posted: 02 Mar 2018 05:49 PM PST Something I've occasionally wondered about but I can't find clear information about. Wouldn't it be a bad thing to take ibuprofen or paracetamol for a throat ache or other discomforts like fever which you know are probably caused by, for example, a viral infection such as flu, as inflammation is how the body clears a virus? Or is there a lot more to it than this? [link] [comments]  |
| Do certain languages have unique speech impediments? Posted: 02 Mar 2018 10:55 AM PST There are certain ones, like stuttering, that seem universal. Are there any that only apply to one language or a select group of languages? [link] [comments]  |
| Is it possible there is another planet in the same orbit as us locked behind the sun always? Posted: 03 Mar 2018 12:42 AM PST Would we be able to tell it existed? I'm imaging we find out there's always been another populated earth behind the sun. [link] [comments]  |

| what is reflection on a microscopic level? Posted: 02 Mar 2018 02:19 PM PST can someone familiar with quantum optics explain to me what happens when a photon hits a surface an bounces back? what causes the photon to bounce back? why does it bounce off that surface at the same angle as it hits the surface?

| Does reading before bed affect mood the following day based on the themes explored? Posted: 02 Mar 2018 08:41 AM PST I've recently started reading a chapter or two of a book every night before bed. However, I'm worried about the effects of the subject matter on my mood the following day. I've heard that the brain retains information that it receives right before sleep so I'm curious if reading something sad will cause me to be less happy in the morning. The same goes for reading news articles or watching videos before sleep. Will the subject matter and/or themes cause a change in my emotional state? [link] [comments]  |
| How do we know how a reaction takes place? Posted: 02 Mar 2018 07:37 PM PST http://nsb.wdfiles.com/local--files/c-9-5-5-1/Screen%20Shot%202011-10-09%20at%2011.29.23%20PM.png Why does the right side carbon of the fat molecule attach to OH instead of the Na? In this reaction, how do we know the above is true, instead of the following image? https://imgur.com/a/aMidY In the second image, I just took the sodium from NaOH and attached it the the right side carbon group of the fat molecule. Then the OH is attached to the O in the fat molecule. The octect rule is still satisfied. How do we know which reaction is supposed to take place if both images satisfy the rules? How do we come up with an explanation as to why one reaction occurs and the other doesn't? [link] [comments]  |
