- Does a spinning magnet in space eventually stop spinning?
- There have been a few news articles written in the past 24 hours regarding a sudden increase in carbon monoxide on the west coast, but I can't find any reputable sources. Is this accurate, and if so, does it lend credence to a potential Earthquake?
- Why does striking of two metals generate event in electromagnetic field?
- Why C squared?
- I always hear about gravity in terms of planets and objects creating "depressions" in the fabric of space, but space is three-dimensional... why doesn't the explanation of gravity seem to take this into account?

| Does a spinning magnet in space eventually stop spinning? Posted: 01 Mar 2016 12:44 PM PST If a object is placed in space and spun, it will continue to spin forever according to Newton's first law. If the spinning object is a magnet, it will produce a radio wave. My understanding is that this radio wave would radiate energy and therefore slow down the spin of the magnet. [link] [comments]  |
| Posted: 01 Mar 2016 09:03 AM PST These articles seem alarmist in nature (especially as they label it a "carbon monoxide explosion"), but the logic seems sound. Example article [link] [comments]  |
| Why does striking of two metals generate event in electromagnetic field? Posted: 02 Mar 2016 04:32 AM PST I have designed a device for listening to electromagnetic fields. The other day I have noticed that I can hear my keys ringing in my pocket with it, even though the event isn't "electric" or "magnetic" in my basic understanding. Then I tried different metallic objects, and indeed I could hear them ringing in the electromagnetic field. What is the exact reason for this? Thanks. [link] [comments]  |
| Posted: 01 Mar 2016 11:50 PM PST Hello. In the equation E=MC2, I get that it's saying energy = mass, and the speed of light squared is how to convert between the two... So it could also be written as: E divided by C squared = mass. Firstly, I'm confused about what the measurement is here.. what is the common measurement comparing mass and energy? And the question that I'm the most interested about... Why is it C squared? Thanks [link] [comments]  |
| Posted: 01 Mar 2016 03:19 PM PST It seems like there has to be a more accurate way of visualizing what this looks like in 3D. Gravity waves here Depressing Fabric o' space here [link] [comments]  |
| Posted: 01 Mar 2016 07:22 PM PST It seems that many, if not the majority, of fruits and vegetables we commonly eat around the world today came from the Americas. What foods allowed civilization flourish in the Old World? [link] [comments]  |
| What would a photon sphere look like? Posted: 01 Mar 2016 01:49 PM PST https://en.wikipedia.org/wiki/Neutron_star As we all know, photons can become trapped in orbits around neutron stars or black holes creating a photon sphere. (duh!) The above linked wiki states in the Properties section that a photon sphere would render the entire surface of a neutron star visible. My question being; is this accurate, and if so, what would that visually look like? My friend claims it would be a highly distorted image, to the point of being incomprehensible, since the photons you could see would be the one-off ones escaping orbit and reaching your eye. Would there be some kind of coherent image, albeit very distorted? [link] [comments]  |
| What's the curvature of the universe? Posted: 01 Mar 2016 11:16 AM PST More precisely, what are the bounds? I've found something saying that it's 1.00 ± 0.02, but that doesn't have any units so obviously it's a form I'm unfamiliar with and it's completely unhelpful. What is it in inverse lightyears?

| Posted: 01 Mar 2016 06:53 PM PST I am not asking about the drugs they use, or any medical use of them. I saw someone use a multi-dose pen and the mechanics of it all just blew me away. I am fascinated by how they actually work, and how they perform what seems like a high-tolerance task repeatably, affordably, and in a sanitary manner. [link] [comments]  |
| Posted: 01 Mar 2016 10:00 PM PST This topic came up earlier during an episode of wild Amazon Prime shopping. Amazon has a HUGE shipping and delivery network, but could they deliver a mountain the size of, say, Nevada's Mt. Charleston by Saturday afternoon? It should be noted that everyone at work is now invested in this answer. Most of the people I work with think it's possible, but I've got my doubts, so I figured this would be there place to ask.

| Ask Anything Wednesday - Economics, Political Science, Linguistics, Anthropology Posted: 02 Mar 2016 07:02 AM PST Welcome to our weekly feature, Ask Anything Wednesday - this week we are focusing on Economics, Political Science, Linguistics, Anthropology 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]  |
| Why does my bathroom window cause the light from the street light outside to form this pattern? Posted: 02 Mar 2016 02:40 AM PST The pattern also seems to change in ways that don't make sense to my eyes, moving a small amount forward or backward causes it to expand and contract a lot.

| [Physics] Do substances have aliasing at an atomic level? Posted: 02 Mar 2016 06:20 AM PST It seems to me that they would, except for the fact that atoms aren't tied to a grid like pixels. Has this ever been looked at by anyone? [link] [comments]  |
| AskScience AMA Series: Kumar Sanjiv, Cancer Researcher Posted: 02 Mar 2016 06:08 AM PST Hello, My name is Kumar sanjiv, I am working at Helleday Laboratory, karolinska Institute. We are developing new cancer therapies by targeting DNA repair proteins. Before coming in to research, I worked 3 year as veterinary doctor. In my spare time I like to play with my kid and to watch movies. My favorite Bollywood movies are 3 Idiots and Barfi. I grew up in northern India and completed my most of education in India before moving to Taipei, Taiwan to PhD in Molecular medicine. During my childhood I was influenced by my maternal grandfather, who was a physicist. [link] [comments]  |

| Posted: 02 Mar 2016 05:51 AM PST Or is there a structure? I've read that we used to believe mesosome would be related to aerobic respiration, nowadays many believe that structure doesn't exist... so... I am confused... I would appreciate some help.

| How come crystals like Diamond don't conduct electricity? Posted: 01 Mar 2016 06:57 PM PST If a current works by the flow of charge down an atomic lattice why not in crystals which have a symmetrical structure? [link] [comments]  |

| In relations to animal behavior, what is structural and consequential behavior? Posted: 01 Mar 2016 03:40 PM PST For a project I'm doing, I have to identify seven listed behaviors as either of those, or give a relational description of behavior. [link] [comments]  |
