| What happens to your voice if you don't speak for a very long time? Posted: 02 Jun 2019 10:51 PM PDT I'm writing a story and a woman in the story is unfrozen after 2000 years, not speaking for that amount of time obviously. I was wondering if your voice would be completely gone due to that or if your voice would just be really hoarse? [link] [comments]  |
| Posted: 03 Jun 2019 05:17 AM PDT I usually put on my saved songs playlist on spotify, and find that each time I end up listening to my most preferred music. Really keen to figure out if "shuffle" is really random, or if it's programmed to prioritize music I listen to often. [link] [comments]  |
| How / Is domesticated behaviour carried into genes ? Posted: 03 Jun 2019 04:38 AM PDT Most dogs are friendly to humans. I assume this comes from a long term mutually beneficial relationship since prehistoric era. How that familiarity is passed through generations (if it is). Is every dog a "subwolf" that need to be updated through training that Human is the alpha etc... Or they already "know" us and are genuinely symbiotic (For the lack of other words) to us ? same could be applied to horses and cats. But dog feels like a prime case. [link] [comments]  |
| How do stoplights actually work? Posted: 03 Jun 2019 12:34 AM PDT I'm a delivery driver and just today while waiting a few miniutes at one did I actually question the science behind it. My question is what sensor is used to get a signal and what logic is behind the programming when it gets a signal? [link] [comments]  |

| Has Cancer always existed or is it a modern disease? Posted: 03 Jun 2019 04:53 AM PDT Is cancer a product of our modernization? Or has it always existed even for much older generations like in the 12th century and the like? Did it exist in a different name? Etc etc [link] [comments]  |

| Can single-celled organisms become cancerous? Posted: 02 Jun 2019 01:05 PM PDT Cancer happens in animal cells, and plant cells to a lesser extent, when the mechanism that controls when cells divide and how many times they should divide fails and the cells start dividing out of control. Can the same thing happen in a single-celled organism, where the timing mechanism fails and the organism just starts undergoing uncontrolled cell division? [link] [comments]  |
| Why are Neanderthals considered a different species? Posted: 02 Jun 2019 06:57 PM PDT From what I remember in science class, two different species can't produce fertile offspring. For example, a horse and a donkey can create a mule, but mules are sterile; therefore, horses and Donkeys can't have fertile offspring and are separate species. But Many modern humans have Neanderthal DNA, meaning that Neanderthals must have interbred with our ancestors and produced fertile offspring. Wouldn't that make Neanderthals the same species, by definition? [link] [comments]  |
| Posted: 02 Jun 2019 12:00 PM PDT One might expect a fairly uniform distribution of molecules under the conditions of a supernova, so then how do all the gold atoms find each other so as to form the veins that we ultimately find in mines? Why are there separate "copper mines" and "gold mines" and not just "mines"? [link] [comments]  |
| What happens in regions of space where opposing ergosperes overlap? Posted: 02 Jun 2019 12:09 PM PDT Let's say we had two rotating black holes rotating in the same direction. If they were close to each other, the ergospheres would overlap. In the overlapping region, we have a paradox. An object in that region would be locally exceeding the speed of light regardless of its motion. Standing still would violate both ergospheres. But moving with either one would violate the other. Granted there might be some tidal forces, but that is just an engineering problem. Imagine your (hopefully unmanned) space probe is made of very strong nonobtanium. [link] [comments]  |
| How can we count the number of protons and neutrons in the nucleus? Posted: 03 Jun 2019 04:23 AM PDT Today we know that the atomic nucleus is made up of protons and neutrons, and how many there are/should be in the various elements. But I have 2 questions:

| Posted: 02 Jun 2019 09:50 PM PDT I understand they work based on magnetic inductance, but I don't understand how the detector is able to identify the presence of a metal and its magnetic field? [link] [comments]  |

| Was a shot through the lung survivable in the past? Posted: 02 Jun 2019 05:28 PM PDT I remember that i watched a couple of old american western movies which show characters getting shot in the chest (right side) after the town physician examines the person in question they explain that he will make it since it is only a clean shot through the lung. Was it possible to survive something like that back in the 19th century, while living in a town far away from a proper hospital? [link] [comments]  |

| Posted: 02 Jun 2019 03:10 PM PDT Computers simulate multitasking by switching focus between different tasks quickly so it feels like they're doing everything at once. So which is it for the human brain? And is it even possible to test/prove it? [link] [comments]  |
| Why can I see window tint patterns with my sunglasses on? Posted: 02 Jun 2019 08:28 AM PDT Just that, I noticed with some sunglasses I can see patterns in some car window tint that I cant see without. What is causing this? Im told its because the glasses are polarized, but hiw does that cause this effect? [link] [comments]  |
