| What is the base of a mountain? Posted: 02 Nov 2019 11:34 AM PDT The Wikipedia article on mountains says the following:
What is the base of a mountain and where is it? Are the bases of all mountains level at 0m? What about Mauna Kea? What is the equivalent level for mountains on other planets and on moons? What do you call the region or volume between the base and peak? [link] [comments]  |
| How does general anesthesia render you unconscious? Posted: 02 Nov 2019 11:06 PM PDT I've been trying to find an answer to this question but the explanations online range from "nobody knows" to "quantum vibrations in microtubules" and none of it seems to make much sense. What does the anesthetic actually do in the brain to affect consciousness? [link] [comments]  |
| When Ice Melts Does It Increase The Water Level? Posted: 03 Nov 2019 02:52 AM PST I'm curious. If an iceberg (fresh water) melts does the level of the body of water its in (salt water) rise at all? Basically what I mean is since part of an iceberg is above the water line shouldn't more volume be added to the surrounding water as it melts or is the volume of water it displaces going to be exactly the same? Also for example let's say I take a half submerged ball in a kiddy pool and I press down on it. The water rises correct? [link] [comments]  |
| Posted: 03 Nov 2019 03:14 AM PST I read something somewhere that implied this. Can anyone explain the science? [link] [comments]  |
| How are the compositions of Asteroids determined? Posted: 02 Nov 2019 04:03 PM PDT I know a little about asteroids, like how we use "spectography" in order to say what an asteroid is made of. I'm curious how this process actually works. How does seeing the color and wavelength let us determine what the asteroid is made of? Also, isn't this essentially just telling us what is on the outside? How could we know what is inside the asteroid? Surely an asteroid is not simply a homogeneous mass of the same mineral.

| How does the brain tell the heart to beat? Posted: 02 Nov 2019 11:14 PM PDT I just saw a clip on r/medizzy where a heart is shocked back into the correct rhythm during surgery. My question is, how does the heart know to beat? I know that the brain controls all of this but how is that info sent to the heart? I would guess that nerves might have something to do with it but I am the farthest thing from a doctor (industrial refrigeration operator) so searching google gives me explanations that I cannot comprehend at all. I hope the question is understandable because I'm having a hard time explaining what I don't know. [link] [comments]  |
| Could particle interactions generate very weak, microscopic gravitational waves? Posted: 03 Nov 2019 01:55 AM PDT Obviously we'd have no way of detecting them since we can only just detect large scale gravitational waves. However, is it possible that insanely small gravitational waves are constantly generated all around us from particles passing eachother, etc? [link] [comments]  |

| How do tablets get dispersed into our body? Posted: 02 Nov 2019 06:25 PM PDT So tablets that require oral ingestion. We swallow, they hit our stomach and dissolve and go into the blood stream but actually how? Surely our stomach acid would melt everything down before it can be useful especially in such tiny pills etc so how does it actually work? [link] [comments]  |
| Posted: 02 Nov 2019 03:26 PM PDT I haven't heard anything about this so I assume the answer is yes. Once we knew there wouldn't be a Big Crunch, everything I've read says there will eventually be a heat death. [link] [comments]  |

| Why does biological matter make good fertilizer? Posted: 02 Nov 2019 12:09 PM PDT Now hear me out. I'm not stupid. I really love learning and I know that when biological matter, like feces, breaks down, it releases alot of chemicals and elements that are good for plants. I also know that most, if not all, life on Earth need these chemicals and stuff to survive. My question is why? Why are these chemicals released by our waste and why are they so good for plants and things? Basically, I know they need them, but I don't quite understand the exact reasoning. [link] [comments]  |
| Why do weather reports use relative humidity instead of absolute humidity? Posted: 02 Nov 2019 07:21 AM PDT 100% humidity on a hot summer day feels clammy and unpleasant. 100% humidity on a cold winter morning is fine - the air is saturated, but because it's cold it can't hold much moisture. So why not report the absolute amount of moisture in the air? This is what people already understand humidity to mean. [link] [comments]  |

| Do immune cells circulate in and out of the brain? Posted: 02 Nov 2019 12:25 PM PDT Do immune cells circulate in and out of the brain? Or, do they only cross the blood-brain barrier during an injury? I've been looking around for an answer but can't seem to find one. [link] [comments]  |
| Posted: 02 Nov 2019 08:10 AM PDT I was watching a video about why instruments sound different when in the video it was mentioned that the 2nd harmonic spikes when a piano is played while the 5th harmonic spikes when a guitar is played. It was never said why this is and I wondered if my fellow science loving redditors could figure out why. [link] [comments]  |

| How do Space Probes travel differently? Posted: 02 Nov 2019 06:43 AM PDT What is the mechanism behind Space Probes like Voyager 1 being sent to fly-by the planets and off out into interstellar, compared with probes with Cassini which are meant to be captured in a planet's orbit to study that specific planet? Are they sent at different velocities or are they sent on a trajectory closer to the planet in order to be captured by its gravity? Apologies for the inane questions. [link] [comments]  |
| Why do some people develop reactive arthritis after infection? Posted: 02 Nov 2019 02:08 PM PDT Some people will have an autoimmune reactive arthritis triggered by certain infections. Why are some people prone to this autoimmune reaction while most are not? Are these individuals also prone to other types of autoimmune diseases? [link] [comments]  |
| What happens to artificial sweetners after we ingest them? Posted: 02 Nov 2019 01:38 AM PDT Regular sugars can be broken down into glucose for example and participate in many metabolic processes in the body which yield energy or it can be stored as fat or glycogen, but manufacturers of artificial sweetners boast that their product is "zero calorie." Does this mean that artificial sweetners are simply never absorbed into the bloodstream? How physiologically or chemically can an artifical sweetener avoid winding up as a potentially unhealthy product like LDL, TAG or glycogen? [link] [comments]  |
