| Posted: 22 Aug 2017 02:53 PM PDT I'm just curious, do we suspect there could be thousands/millions of unidentified elements within our universe or are we confident that we've identified most of them? Also, we are constantly searching the universe for potentially inhabitable planets (i.e., oxygen, h2o rich). Do we know if there are elements similar to these which could allow for human consumption? In other words, what are the odds of an unidentified element that humans could breath that is different than oxygen or drink other than water? Edit: words and rephrasing [link] [comments]  |
| What is the probability of the number 3 being the middle square of a sudoku puzzle? Posted: 23 Aug 2017 04:59 AM PDT I've been debating with my SO's father as I thought it would just be 1/9. However, he is adamant that this is not the case and claims his maths teacher friend agreed with him but couldn't give an exact figure. He claims that because the numbers in the surrounding squares influence it it's not simply one in nine, but I'm having trouble seeing it. [link] [comments]  |

| How can the constituents of carbon-12 add up to more than 12 u? Posted: 23 Aug 2017 06:21 AM PDT The unified atomic mass unit (u) is defined as a twelfth the mass of a carbon-12 atom. According to Wikipedia and other sources, a proton is about 1.007 u and a neutron about 1.009 u. That means carbon-12 should be about 12.10 u, even though by definition it is exactly 12 u. Using more significant figures or accounting for the electrons doesn't change the fact that the result is more massive than 12 u. What gives? Shouldn't a proton, a neutron and an electron together add up to exactly 2 u? [link] [comments]  |
| Ask Anything Wednesday - Physics, Astronomy, Earth and Planetary Science Posted: 23 Aug 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]  |

| Why do a punch and a slap sound different? Posted: 23 Aug 2017 07:15 AM PDT Obviously they're different actions and disturb the surrounding air in different ways, but what about the fist vs open hand makes the sound a low thud vs a high pitched smack? [link] [comments]  |

| What is the difference between normal space time and Euclidean space time? Posted: 22 Aug 2017 08:24 PM PDT From what I understand, normal space time is flat and Euclidean space time sounds like a sphere [link] [comments]  |
| Why do electrons carry energy (like, in a wire)? Posted: 22 Aug 2017 08:51 PM PDT I was thinking about how the would be a shortage of copper if all people had equal access to electricity. And it followed that silver is better for moving electrons than copper, but more rare and thus more expensive. Then I thought about glass, which is used for fiber optics---sending photons very fast through a wire---and I thought, why can glass moving photons NOT carry usable energy but electrons moving through a copper wire can? What makes an electron carry that energy that can be used in our appliances? [link] [comments]  |
| Do vaccine immunities get passed down to your children? Posted: 23 Aug 2017 03:29 AM PDT I know in the past different colonies have had different immunities which would suggest they were passed down through genes. Although I've never heard anything about not vaccinating your kid because you were vaccinated. [link] [comments]  |
| How long does it take for us to complete replace all the water in our body? Posted: 22 Aug 2017 01:40 PM PDT Since we lose water constantly by for example breathing or sweating i was wondering how long does it take for us to completely replace the water in our bodies? [link] [comments]  |
| Posted: 22 Aug 2017 12:13 PM PDT I read that mining is "racing" to solving an algorithm, resulting in one bitcoin. What I don't know is what algorithm is it solving? [link] [comments]  |
| Can Radiation (Nuclear or Otherwise) melt skin? Posted: 22 Aug 2017 11:01 PM PDT I'm writing a story that's post apocalyptic and I want to be as realistic as possible, so I want to know that, if one were to survive radiation of some sort, would the radiation itself cause your skin to melt, or would it just be the intense heat? [link] [comments]  |
| Is UV light reflected by a mirror - or is it absorb into the actual glass? Posted: 22 Aug 2017 12:44 PM PDT After the PSA everyone recieved that starring into a UV light source may not be the greatest idea, I wondered if sunlight could transfer damaging UV rays when refelected e.g Sun reflection from a mirror. Thanks. [link] [comments]  |
| What happens to a text sent to a phone that doesn't have texting capabilities? Posted: 22 Aug 2017 01:06 PM PDT Like a landline. Does it sit waiting somewhere to be delivered? Or does something somewhere detect that it can't be delivered and deletes it? [link] [comments]  |
| If someone can't feel pain, do they technically have endless physical endurance? Posted: 22 Aug 2017 09:18 PM PDT Isn't the build up of lactic acid the only factor/pain preventing humans from performing gruelling exercises for prolonged periods of time? [link] [comments]  |
| how do stylus pens with buttons (bamboo-wacom) never run out of battery? Posted: 22 Aug 2017 02:52 PM PDT I can't get an answer any were so I thought Reddit could help [link] [comments]  |
