| How do dogs figure out which posts/trees they want to pee on? Posted: 28 Jun 2017 07:43 AM PDT My dog, like any male dog, does the whole 'marking his territory' thing about once a block. Sometimes more, sometimes less. I notice that a lot of times he picks the same spots, which makes sense to make a clearly defined territory, but when we go somewhere new, he'll still do it, but not on every pole. And when he does want to he's quite stubborn and won't move on until he marks it. Is this just random? Does he only do it on other dogs' marks? I'd assume just about every pole has been peed on at some point. How do they decide? [link] [comments]  |
| Ask Anything Wednesday - Physics, Astronomy, Earth and Planetary Science Posted: 28 Jun 2017 08:07 AM PDT 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]  |
| What happens if the event horizon of two black holes touch? Posted: 27 Jun 2017 07:57 PM PDT Can one be ripped apart or will they be forced to combine completely? If that's the case how long would it take? [link] [comments]  |
| Posted: 28 Jun 2017 07:47 AM PDT I recently had something welded for part of a project. 2 pieces of Aluminum. I talked to a local welder who said he wouldn't touch Aluminum but would have welded my design if it was stainless steel and that I needed to find someone else. Why is Aluminum so much more challenging to weld? What physical properties for Al are different that make it that much harder? [link] [comments]  |

| Do black holes swallow dark matter? Posted: 28 Jun 2017 07:14 AM PDT We know dark matter is only strongly affected by gravity but has mass- do black holes interact with dark matter? Could a black hole swallow dark matter and become more massive? [link] [comments]  |
| Why don't you get shocked when touching a tree that is touching a powerline? Posted: 28 Jun 2017 01:11 AM PDT Most powerlines aren't insulated, so in the case of a powerline touching a tree, wouldn't you also be shocked if you touched that tree? [link] [comments]  |
| What did earth look like 16 million years ago and 12 million years ago? Posted: 28 Jun 2017 06:32 AM PDT Hey. I'm a ranger working on a site with 12 myr old fossils and I'm trying to better understand the conditions in which they were created. Were parts of the modern continents still joined together? Or was it more or less the same as today? I'm in Iceland more specifically and the "earth" (can't remember the correct english term right now, the rocks) where I'm situated is around 16 myr old. Thanks! [link] [comments]  |
| Posted: 28 Jun 2017 12:34 AM PDT How would the nuke's blast affect Earth's atmosphere, (or the Earth itself) if at all? Would there be any other consequences? [link] [comments]  |
| Why does water "stick" to surfaces while upside down and run down them without simply dropping off? Posted: 27 Jun 2017 12:09 PM PDT For example, when you're washing your hands and a water droplet runs down your arm into your sleeve. [link] [comments]  |
| What is the relationship between 3G and 4G? Posted: 27 Jun 2017 01:25 PM PDT |

| Can we derive the laws of thermodynamics from the laws of classical mechanics? Posted: 27 Jun 2017 01:44 PM PDT Suppose we had a box containing billions of tiny billiard balls, all subject to classical mechanics with perfectly elastic collisions. Could we then mathematically prove the thermodynamic laws and relations about temperature, pressure, entropy etc. for this system? It seems that most statistical mechanics books make the assumption that "all microstates are equally probable", but they never prove it. [link] [comments]  |
| Can you help me fix my confusion on gravity assists? Posted: 27 Jun 2017 03:41 PM PDT I know my reasoning or intuition is faulty but I just can't find why. In understanding, one could define a gravitational potential field on our solar system but in that gravitational field, the energy is conserved. So how can different routes through this gravitational field result into different velocities? I mean, I gain energy by passing a planet but I lose it to when I leave it. Obviously this thinking is wrong somehow, maybe some basic assumptions but I can't quite see how gravitational assists operate. Can you solve this or re-explain it? [link] [comments]  |
| What makes something an acid and what makes something a base? Posted: 27 Jun 2017 11:09 AM PDT I've heard somewhere that acids have a sour taste and a bases have bitter tastes. But I've heard that water is a base and acid? This confuses me a lot. [link] [comments]  |
| Can helium bond with other elements or with itself? Posted: 27 Jun 2017 10:35 AM PDT Is it possible for helium to bond to create other substances? I know helium is a noble gas and is extremely unreactive because of its full outer shell but is it possible? [link] [comments]  |
| how much more radioactive is enriched uranium compared to depleted uranium? Posted: 27 Jun 2017 03:37 PM PDT |
| would strange matter blow up 'normal matter'? Posted: 27 Jun 2017 04:55 PM PDT I am asking if matter with strange quarks could be in the same nucleus as matter with just up and down quarks and still be stable, i am also asking if strange matter could possibly be included in atoms and molecules and if we really know any of its properties in the first place.
