| Would headphones tangle in space? Posted: 19 May 2016 01:11 AM PDT My guess is that the weight of the cables in a confined space (eg a pocket) acts on tangling them. If they are confined when they are weightless would the cable not just stay separated? Entropy? [link] [comments]  |
| How long does it take for a human body to totaly disappear in the ocean (water)? Posted: 19 May 2016 01:06 AM PDT *totally So I was reading about the Malaysian airplane that disappeared two years ago and about the debris they think they found. If the people died in a crash, would the bodies decompose because of the water (with help of the water)? [link] [comments]  |
| Posted: 18 May 2016 03:39 PM PDT The cosmology course i'm studying right now mentions very briefly that standard rods exist. I'm intrigued, but can't find any examples online. Can any astronomers help? [link] [comments]  |
| What's the difference between a mutagen and a carcinogen? Posted: 18 May 2016 06:59 PM PDT I work with ethidium bromide in the lab, and was told that it was a mutagen by my professor. He said he's not sure why it's not considered a carcinogen, as cancers are caused my mutations, and the mutagen causes mutations. Can anyone clarify? [link] [comments]  |
| Posted: 18 May 2016 09:15 PM PDT I remember being told that if you were to watch someone fall into a black hole, at a certain point they would seem frozen in place forever (as light can't escape beyond this point). If a lot of stuff has fallen into a black hole, would we see a jumble of clutter at the event horizon of everything that has ever fallen in? I'm imagining a static version of the win screen of the old solitaire on Windows (https://www.winningsolitaire.com/) [link] [comments]  |
| Can I smooth this rock with just my hand? Posted: 18 May 2016 10:46 PM PDT This specific rock. I want to smooth it until the sharp edges are gone and it resembles this. As a meditation in restraint, I want to do so purely by hand. I mean with my hand, not with hand tools. From those pictures (sorry for the quality) and without any kind of chemical assessment, would one of you geologists with wizardly powers identify the kind of rock? If it helps, it was sourced from the beach of Whidbey Island in Washington State. Would I be able to smooth it by hand in a couple weeks, months, years, ever? Or am I just going to be rubbing my hand raw? I mean, that would still be a valid exercise, but my hope is that it's possible, and hpoefully in some very short timeframe. I was planning on doing so just about any time I have a free hand (lunch, on the bus, reading in bed). Thank you for any help, even if it's just a tip that there's another subreddit I should post in!

| Composition of the Moon: Why So Plain? Posted: 18 May 2016 07:58 PM PDT If the Moon was formed from the Earth after a comet or planet strike then why is its composition nothing like Earth's? I've heard that lunar regolith described as being like ground glass, very sharp, etc. Now this can be explained by the lack of erosion processes, however that brings up another question. Why does it not have water or even a light atmosphere if it was borrowed from Earth? [link] [comments]  |

| Ask Anything Wednesday - Biology, Chemistry, Neuroscience, Medicine, Psychology Posted: 18 May 2016 08:04 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]  |
| What is the reason for the Dark Matter/Dark Energy hypothesis? Posted: 18 May 2016 01:38 PM PDT In particular,it seems like there was a view of the way the universe worked (Big Bang, Expanding and/or contracting universe, etc.), what problem came up that made someone propose Dark matter and/or Dark Energy as a solution?

| Creating suction with gravity ? Posted: 18 May 2016 03:05 PM PDT Is there a way to create suction using an elevated liquid source and a pipe system that flows from the bottom of the container and wraps under then above? A self sustaining waterfall so to speak. [link] [comments]  |
| How do animals know where to strike? Posted: 18 May 2016 07:11 PM PDT Like when wolves throat clamp or when animals know you're making eye contact, how do they know it? [link] [comments]  |
| When I'm wearing polarized sunglasses, why does the sky change brightness when I tilt my head? Posted: 18 May 2016 10:09 AM PDT I know the sky scatters light but I only notice a change in brightness closer to the horizon. [link] [comments]  |
