- Can really low pitch, loud sounds damage your ears even if you can't hear them?
- Can scars form on the inside of the body as well?
- Why do the hot gases of a pyroclastic flow down a mountainside rather than rise up into the atmosphere? Don’t hot gases rise?
- Why exactly does water put out fire so effectively? Both oxygen and hydrogen merrily burn, so why is the combination of the two such a great anti-fire agent, from a physics standpoint?

- If something is faster than the speed of sound, it's supersonic. And slower is subsonic. If something is the same as the speed of sound, is it just considered "sonic"?

| Is the volume of Earth's atmosphere constant or does it change? Posted: 08 Dec 2018 03:17 AM PST If i turn 1 litre of liquid water into 100 litres of steam, did i increase the volume of Earth's atmosphere by 99 litres? [link] [comments]  |

| Is fusion power still on track, 20 years later? Posted: 07 Dec 2018 04:39 PM PST In discussions like this one, this graph is often referenced, which shows the progress that's been made in fusion power, measured as triple product vs time: Fusion: figure-of-merit (the 'triple product') doubles every 1.8 years But the last point on that graph is around 1998, 20 years ago. When I Google Image search "triple product over time", this decades-old graph is the only one I see. Is the triple product still doubling every 1.8 years? What would this graph look like if updated to today? [link] [comments]  |

| Do donor organs impact chronic medical conditions? Posted: 08 Dec 2018 02:55 AM PST If a person with a chronic medical condition (not a disease) received a new body part from an affected area, would they still have the chronic medical condition? Ex: if an asthmatic received a lung transplant, would they still have asthma? [link] [comments]  |
| Posted: 07 Dec 2018 09:43 PM PST To add to that how have they also been able to figure out not only the shape of the receptor and molecule that fits in such receptor, but also the effect the molecule has by interacting with the receptor. If im correct I know some receptors can be acted upon in multiple ways that one molecule that fits in the receptor or can interact with it can be an agonist, but also another molecule maybe with a similar shape can fit/interact in/with the same receptor. Scientist obviously can't microscope down to the molecular level to analyze a receptor which is most likely a highly complex 3D Functional portion, so how were we able to come this far to analyze and know the shape of the receptor and its chemical properties. I know scientist can analyze stand alone molecules themselves through NMR, Electronegativity analysis, using ligands; but I don't see how that could be possible being that a receptor is not stand alone and the process of trying to isolate it from the cell would either degrade it or cause it to become unstable. I know I probable asked this question in a way that could possibly need in depth explanation but understanding processes and deducing things to its smaller subunits really interest me which is why many things in biochemistry interest me. If I am also incorrect on anything stated please feel free to correct me. [link] [comments]  |
| Posted: 07 Dec 2018 11:44 PM PST A guy I work with is a either a) a legit flat-earther or b) a Socratic-genius inspiring people to question common beliefs they've taken for granted. One of his argument was that given the motion of our solar system around the spiral arm of our galaxy changing patterns in the night sky ought to be more visible. Are the stars' relative stillness a result of our limited perspective? Perhaps as a result of the (literally) astronomical distances? Or maybe relative motion among the local cluster and other easily visible stars? Or does the night sky change noticeably in a time scale relevant to recorded history? [link] [comments]  |

| Why should anode be dried when measuring Faradays Constant? Posted: 08 Dec 2018 02:47 AM PST I understand that the mass of the anode increases when it is wet but why does it decrease faradays constant? [link] [comments]  |
| When did paleontologists and geologists first estimate the age of fossils and rocks? Posted: 08 Dec 2018 02:36 AM PST I'm trying to find a resource relating to the history of geological dating methods, and also to early thinkers who first asked these questions. [link] [comments]  |
| Do planets stay on the same path when orbiting the sun, or do they move on a Y axis? Posted: 07 Dec 2018 08:35 PM PST In case my title didn't properly convey what i was asking; in most renditions of the solar system, all the planets are depicted as being level with each other when orbiting the sun. are the planets of our solar system actually level with each other, or do they vary in levelness with the other planets?

| Is an element's emission and absorption spectra identical? And what can that imply? Posted: 07 Dec 2018 10:48 PM PST If an element only absorbs certain wavelengths of electromagnetic radiation are the wavelengths it gives out identical? So matter only absorbs or reflects electromagnetic radiation? Are those the only two possible modes of interaction between the two? I will have lots more questions once the answers start pouring in.

| Posted: 07 Dec 2018 08:50 PM PST We seem to be able to detect black holes which are growing faster than others: https://earthsky.org/space/astronomers-find-fastest-growing-black-hole But since from our frame of reference - we can never observe anything falling past the event horizon of a black hole - doesn't it follow that we could never observe their growth? Since matter appears to slow down as it approaches the event horizon - wouldn't we expect to observe matter to appear increasingly dense around the event horizon? What would this even look like? Presumably - if supplied with enough additional mass over time - the space immediately around the event horizon would appear to contain a density of mass greater than that required to form a singularity itself. Matter further away from the event horizon would appear to be moving quicker toward the matter closer to the event horizon - and thus would approach, but never catch up to the matter closest to the event horizon itself.
