| Do animals in the wild get STDs? Posted: 06 Mar 2018 07:32 PM PST I imagine that most animals have many different mates and that there is no concept of safe sex, so if they don't have STDs like humans do, why not [link] [comments]  |

| What do the true orbits of planets and around the Sun look like? Posted: 07 Mar 2018 04:24 AM PST I have a 5th grade understanding of how planets orbit the Sun. Where can I find a true depiction of how all the planets orbit the Sun? In my mind and how we were taught was that visually they orbit all on a flat plane. That can't be possible, that's why I'm asking. [link] [comments]  |
| Posted: 07 Mar 2018 06:39 AM PST Assuming the craft hasn't been exposed to harsh winter conditions. Say similiar to the brakes on a Formula One car. [link] [comments]  |
| How are space telescopes shielded against cosmic rays? Posted: 07 Mar 2018 02:43 AM PST Space telescopes usually record photons as counts by converting their energy into an electric signal. But seeing as how cosmic rays may register as counts as well, I'm assuming they somehow need to be kept out of the equation. But how is this usually achieved? [link] [comments]  |
| Ask Anything Wednesday - Physics, Astronomy, Earth and Planetary Science Posted: 07 Mar 2018 07:07 AM PST Welcome to our weekly feature, Ask Anything Wednesday - this week we are focusing on Physics, Astronomy, Earth and Planetary Science 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]  |

| Posted: 07 Mar 2018 07:38 AM PST In big energy storage projects, are the power and energy determined mostly by the arrangement of all of the batteries? For example, if I have 16 batteries in a 4x4 arrangement (4 in series, each string in parallel), maybe I get 400kW/400kWh. Can I change that to a 2x8 arrangement and have 200kW/800kWh? If a company bought a 400kW/400kWh system, would the cost be the same as a 200kW/800kWh system? [link] [comments]  |
| How does electricity cause magnetism and vice versa? Posted: 06 Mar 2018 08:50 PM PST Im studying electricity (not for a degree or anything, just for fun) and Im a little bit confused on something and everyone I ask seems to shy away from the question without giving me an answer. I understand that flowing electrons can create a magnetic field, and how a changing magnetic field can induce a voltage on a conductor, but im just wondering why? As in whats going on on the electron level, how do electrons and a magnetic field interact with each other? I feel like any answer will give me a better grasp of the concept which would be so awesome thanks for your help!!!! [link] [comments]  |
| Does the pressure of water in a bucket increase if I swing the bucket around in a circle? Posted: 07 Mar 2018 02:36 AM PST In the classic "bucket" demonstration of centrifugal force (example here: http://www.physicscentral.com/experiment/physicsathome/centripetal-force.cfm ), does the pressure of water in the bucket increase when I swing the bucket around? What about a bucket of air - will the air pressure in the bucket increase as I swing the bucket around? If so, then if I invert the bucket so the open end is facing outward, would the pressure of air in the bucket decrease as it is swung around? With enough speed (and very strong arms), could a vacuum be formed in the bucket? [link] [comments]  |
| Is there a limit to the width of lightning ? Posted: 06 Mar 2018 12:15 PM PST I have never seen lightning closeup but guess it to be around 10cm diameter, with its actual size proportional to the energy being transferred in the single (sustained) arc My question to the science community is are there upper or lower limits on the width of lightning when there is a single strike hitting the ground, thanks. Ps. I guess it's a physics flare, [link] [comments]  |
| Is the total energy of the universe constant? Posted: 06 Mar 2018 05:44 PM PST During a class of thermodynamics, it hits me that first law is the conservation of energy; energy can't be created nor destroyed. So is the total energy of the whole universe a set amount? [link] [comments]  |
| Why does it rain in South Caucasus in Summer but in North Caucasus in Winter? Posted: 07 Mar 2018 02:41 AM PST Hi there, So, I am a geography lover from Azerbaijan, and I have been questioning a certain phenomena for a while. Well, Azerbaijan is a subtropical country with Mediterranean climate, so most of the rain (600 mm is the annual average) here drops in winter. But, in the mountains of South (or lesser) Caucasus rain drops mainly in summer (about 800 mm a year). I am wondering why is this so. I think it would be helpful if I would supply you with some important geographical features.
The map can be found here Thanks beforehand! [link] [comments]  |

Posted: 06 Mar 2018 02:49 PM PST https://www.quantamagazine.org/physicists-find-a-way-to-see-the-grin-of-quantum-gravity-20180306/ If gravity is confirmed to be a quantum phenomenon, does that mean that the graviton will have been confirmed to exist?
