| What would be the implications if the existence of a magnetic monopole was found? Posted: 01 Mar 2017 11:27 AM PST I know from university physics that thus far magnetic poles have only been found to exist in pairs (i.e. North and South poles), yet the search for isolated magnetic pole exists. If this were to be found, how would it change theoretical physics? [link] [comments]  |

| Posted: 02 Mar 2017 07:42 AM PST This picture seems to be popular this week: If you were to ask someone who has never seen strawberries before, would they still say they look red? (i.e: am I "seeing" red because I know strawberries are red?) [link] [comments]  |
| Would stars be visible from the daylit side of Ganymede? Posted: 02 Mar 2017 02:38 AM PST I just got finished watching the most recent episode of "The Expanse" and part of the action takes place on the surface of Ganymede. As the camera follows the action, in the background you can see the stars above the horizon, but it's pretty clear that the action is taking place during the day. My question is, is daylight dim enough on Ganymede so that the stars would still be naked-eye visible? or is it still bright enough like our own moon where adjusting cameras to image the surface (and presumably our own eyes) renders the stars invisible?

| How can the electromagnetic and weak interactions be unified, if they have different gauge bosons? Posted: 02 Mar 2017 12:01 AM PST The electromagnetic interaction is carried by photons, while the weak interaction is carried by W and Z bosons. How can it then be that these two forces are in fact the same force, the electroweak interaction? [link] [comments]  |
| How can photons not have mass? Posted: 01 Mar 2017 11:02 PM PST I thought that everything in the universe had mass in some form or another. So why is it that photons don't have mass? [link] [comments]  |
| Posted: 01 Mar 2017 09:18 PM PST I have high-school level knowledge of basic particle physics, and I think I know that the Higgs boson's interactions with particles more or less "give them mass," but I know that's an overly simplified explanation and that the exact interaction is probably way more complicated.

| Why doesn't FTL quantum tunneling violate causality? Posted: 01 Mar 2017 08:39 AM PST It seems that a bunch of experiments confirmed that particles tunnel through barriers faster than what would be expected if they were traveling normally at the speed of light. I'm referring to a study specifically by the Keller group in 2008 but this seems to be the consensus today (according to Wikipedia at least). I'm not ready to believe that relativity would fail so quickly and I'm inclined to think that even if FTL tunneling is possible, it wouldn't allow FTL communication. But I fail to see how that's the case. edit: corrected group name to 'Keller group' [link] [comments]  |
| Are some people more psychologically prone to developing a phobia or PTSD? Posted: 02 Mar 2017 02:02 AM PST I'm wondering if any environmental or genetic factors are known to influence the likelihood that someone will develop a phobia or PTSD? There have been instances in my life that where others may have developed a phobia or anxiety, I developed none. Examples:
Others I have spoken to who experienced the same things have told me they developed a phobia or PTSD for which they sought therapy. [link] [comments]  |

| How does an internet server know at what speed to transmit you data? Posted: 01 Mar 2017 10:40 AM PST Chances are your internet connection is much slower than any server's where you're downloading stuff from. So what happens if the server "floods" you by trying to send data at a faster speed than you can download? Is that extra data lost and resent? Is it stored somewhere? Or does the server 'test' your internet connection and then sends data at a slower rate? [link] [comments]  |
| If we forget everything, what do we remember? Posted: 01 Mar 2017 03:49 PM PST This might not be accurate, but in movies and TV shows, you sometimes see a character forgetting "everything," yet saying they "don't know who [they] are." If we purportedly forget everything, then how can we still recall the idea of identity? [link] [comments]  |
| Posted: 01 Mar 2017 03:22 PM PST I asked my high school teacher and looked this up as it popped into my mind during class but was left empty handed. Thanks for any insight you can share on this! [link] [comments]  |
| Can erbium be used to stop a nuclear reaction? Posted: 01 Mar 2017 07:23 AM PST I saw on periodicvideos that erbium is a nuclear poison. It was described as killing any nuclear fission dead. If that is true, at what scale can it do this. Is it possible to produce a sort of safety kill switch for nuclear reactors? Or is the amount of erbium required just too massive? Or is there a reaction that makes this unfeasible? I had never heard of a nuclear poison before. [link] [comments]  |
| Why isn't there a ciritical point on the solid-liquid phase boundary? Posted: 01 Mar 2017 07:11 AM PST On the liquid-gas phase boundary of pure substance there is a critical point above which the liquid phase and the gas phase become indistinguishable. Why doesn't the same happen on the solid-liquid or solid-supercritical fluid phase boundary? I remember this being a possible question in the oral exam for one of my practical courses in physical chemistry. In preparation for the exam my lab partner and I asked dozens of other students and phd students. No one was able to give a satisfying answer. Luckily we weren't asked in the exam, but afterwards we went on and aksed the prof on that subject. His answer was that the phase change solid-liquid is mainly determined by a change of order in the substance. In contrast to that the liquid-gas phase change is determined by the change in interaction of the particles and overcoming of the attracting forces. I found that to be a pretty disappointing, undetailed answer. [link] [comments]  |
| How does a GPS calculate the shortest distance between destinations so fast? Posted: 01 Mar 2017 02:36 PM PST Maps have a subtle depth to them where each intersection has its own rules like no right turns, and certain roads only go in one direction. How did they go about writing an algorithm that takes all of this into account? [link] [comments]  |

| Can I take a protein sample (for DNA Extraction/ PCR) without killing the fish? Posted: 01 Mar 2017 10:50 AM PST Using this kit to catalog the genetic barcodes of trout from various lakes and I wanted to avoid having to kill a bunch of fish. Thanks! [link] [comments]  |
