| Can a Mars Colony be built so deep underground that it's pressure and temp is equal to Earth? Posted: 12 Jul 2016 01:22 PM PDT Just seems like a better choice if its possible. No reason it seems to be exposed to the surface at all unless they have to. Could the air pressure and temp be better controlled underground with a solid barrier of rock and permafrost above the colony? With some artificial lighting and some plumbing, couldn't plant biomes be easily established there too? Sorta like the Genesis Cave [link] [comments]  |
| Why does gold "Blink" when it solidifies? Posted: 12 Jul 2016 08:09 AM PDT I was watching this & i was kinda shocked about the little blink gold does when it solidifies. Is this common amongst other metals? Why does it do that? im guessing it has to do with conductivity [link] [comments]  |
| Posted: 12 Jul 2016 01:30 PM PDT I've been trying to research the way the earth heats up as you get deeper and deeper (geothermal gradient), but the focus is mostly on super-deep gradients for oil, geothermal, or geological surveys. I understand that this depth could vary wildly depending on where you chose, so choose wherever might be reasonable to build an underground city or whatever. :) [link] [comments]  |

| Ask Anything Wednesday - Biology, Chemistry, Neuroscience, Medicine, Psychology Posted: 13 Jul 2016 08:05 AM PDT Welcome to our weekly feature, Ask Anything Wednesday - this week we are focusing on Biology, Chemistry, Neuroscience, Medicine, Psychology Do you have a question within these topics you weren't sure was worth submitting? Is something a bit too speculative for a typical /r/AskScience post? No question is too big or small for AAW. In this thread you can ask any science-related question! Things like: "What would happen if...", "How will the future...", "If all the rules for 'X' were different...", "Why does my...". Asking Questions: Please post your question as a top-level response to this, and our team of panellists will be here to answer and discuss your questions. The other topic areas will appear in future Ask Anything Wednesdays, so if you have other questions not covered by this weeks theme please either hold on to it until those topics come around, or go and post over in our sister subreddit /r/AskScienceDiscussion , where every day is Ask Anything Wednesday! Off-theme questions in this post will be removed to try and keep the thread a manageable size for both our readers and panellists. Answering Questions: Please only answer a posted question if you are an expert in the field. The full guidelines for posting responses in AskScience can be found here. In short, this is a moderated subreddit, and responses which do not meet our quality guidelines will be removed. Remember, peer reviewed sources are always appreciated, and anecdotes are absolutely not appropriate. In general if your answer begins with 'I think', or 'I've heard', then it's not suitable for /r/AskScience. If you would like to become a member of the AskScience panel, please refer to the information provided here. Past AskAnythingWednesday posts can be found here. Ask away! [link] [comments]  |
| Do migratory animals born in captivity exhibit migratory instincts? Posted: 12 Jul 2016 10:42 AM PDT For example, if a monarch butterfly is born and living in captivity, will it try to migrate along with wild monarchs? What about birds, mammals, etc? [link] [comments]  |
| Will the genes I pass to my son be influenced by my life experiences ? Posted: 12 Jul 2016 11:39 AM PDT That is to say, will his genes be natures mix of the genes I was born wit and the genes his mother was born with ? Or have our (mine and those of his mother) genes evolved during our lives such that the next ''iteration' of our genes will be influenced by our nurtured characteristics ? [link] [comments]  |

| How does the neutron core of a Thorne-Zykow object affect the lifespan of it's 'parent' star? Posted: 13 Jul 2016 03:25 AM PDT Does the neutron core produce any outward pressure that could keep the parent star 'alive' past the time it would usually cease fusion and go supernova? Also how is the fusion in the parent core affected by the neutron's presence, does the neutron star accrete any of the core's matter and as a result get pushed past it's TOV limit? Final question - is there any chance that something other than a neutron star can create a TZ object, like another smaller regular star or a white dwarf? I'm very curious about the physics behind these strange wonders and how exactly they interact with each other. [link] [comments]  |
| What caused snowball earth to stop freezing? Posted: 13 Jul 2016 06:37 AM PDT I was watching a documentary and AFAIK it was careening downwards into snowy oblivion and then it just grinded to a halt and started warming back up. I dont feel like micro-organsims, as many as were left could have created a combined CO2 count in the atmosphere to make a difference in temperature. Especially considering they were hidden randomly in the world trying to survive. What else could have contributed to earth heating up? [link] [comments]  |
| What are measurable signs of quality sleep? Posted: 12 Jul 2016 09:05 PM PDT |
| Posted: 12 Jul 2016 06:48 PM PDT So I just read a book that raised an interesting point. Every children's drawings of a house looks the same. You know the typical drawing: A square house with a triangular roof, and always a chimney sticking out of it. Two to four windows, and a highly simplistic door. Individual flowers growing out of the ground. And if a tree is added, it is always an apple tree. I'm going to bet that if your child (or you, as a child) drew like that, your real house looks NOTHING like it. And I'm sure that it's drawn like this all around the world and across multiple cultures and countries. So I have to ask, is there any psychological or social reason for this? Is it because they can't draw complex shapes at such an early age, or is it because of a sort of collective unconscious? [link] [comments]  |

| Are all galaxies eventually going to become spiral galaxies? Posted: 12 Jul 2016 09:07 PM PDT Because of the way gravity works, objects tend to choose a favorable direction and plane of motion. This is why the planets in our solar system all revolve in the same direction and are (as far as I know) on the same plane. Does this principle hold true for galaxies where there are billions of objects which are all massive, and does this mean that all galaxies are eventually going to become spiral galaxies?

| Posted: 12 Jul 2016 12:52 PM PDT A red shirt is red because it absorbs all visible light other than red. How can the shirt continuously absorb all of the other photons? Is the continuous stream of input energy given off through other parts of the EM spectrum? [link] [comments]  |
| Posted: 12 Jul 2016 09:41 PM PDT Would you see it coming from the distance? Would you see nothing and then witness a flash? Would there be a physical or audible shockwave? [link] [comments]  |
| Why are electrical circuits made the way they are? Posted: 13 Jul 2016 05:11 AM PDT I don't really understand why electrical circuits need to be arranged certain ways. Why do we arrange resistors, etc. the way they are? Is it to get current/voltage down to the right level to power devices connected to the circuit? I realize this is somewhat of a vague question I'm finding it hard to put into words. [link] [comments]  |
| How does a woodpecker not get multiple concussions? Posted: 12 Jul 2016 06:37 PM PDT I had to ask after seeing this: http://imgur.com/gallery/uGvLn Isn't the brain smacking the inside of the skull repeatedly?? Do they have some kind of safeguard in there exclusive to them? [link] [comments]  |
| Which one provides more energy? Protein or Carbohydrate? Posted: 12 Jul 2016 06:22 PM PDT My teacher told me that, if you have a lojg marathon then you should eat proteins because carbohydrates get burn off quickly. But I don't understand how proteins will be able to provide energy? [link] [comments]  |

| When was the biggest leap in human longevity (average life expectancy) and why? Posted: 12 Jul 2016 01:59 PM PDT For example, I remember hearing 25 was old thousands of years ago, so when was the biggest leap in average life expectancy? (From the dawn of our current race, not including early homonids) [link] [comments]  |
