| Posted: 22 May 2019 04:24 AM PDT My thought was black holes are so powerful that nothing escapes so they must be very cold. Secondly if some heat escapes does escape does that mean the area around a black hole is Super hot? Thank you for your answers. [link] [comments]  |

| Ask Anything Wednesday - Economics, Political Science, Linguistics, Anthropology Posted: 22 May 2019 08:12 AM PDT 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]  |
| Will urban areas be considerably quieter when all vehicles become electric? Posted: 21 May 2019 11:22 AM PDT How significant is the amount of sound produced by engines, compared to all the other sounds made in a city? One day when every vehicle on the road will be electric, will overall noise pollution be significantly reduced? [link] [comments]  |

| How do we reach extremely low temperatures? The likes of bellow 50 Kelvin. Posted: 21 May 2019 05:12 PM PDT More specifically, how is rocket fuel frozen to the low temperature that it is? And for that matter, how are the the extreme low temperatures like below a single Kelvin reached? I've tried doing some research into the matter, but neither Google nor Bing were showing me the answers I was looking for. I've tried rephrasing my searches, but in the end I'm hoping at least reddit has what I'm looking for. [link] [comments]  |
| How is the spin of elementary particles without charge determined? Posted: 21 May 2019 10:30 AM PDT I think I understand that the angular momentum of particles with an eletric charge will "give" those particles a magnetic momentum which can be measured. However for elementary particles that possess no eletrical charge I'm unsure of how their spin can be detected and effectively measure. [link] [comments]  |
| What is the smallest known organism that has a multi-chambered heart? Posted: 21 May 2019 09:44 AM PDT How large does an organism need to be for its heart to have distinct chambers and be recognized as what we would usually call a "heart"? I've read that some small organisms have heart-like structures or "false hearts" but I'm having trouble finding information about chambered hearts in small organisms. Can you help?

| Posted: 21 May 2019 08:59 AM PDT I've been wondering this as I'm a very fast eater and have also noticed that it takes me a very long time to become hungry again. I know I'm getting older and metabolism slows down, but am wondering if I can help this with chewing my food more? [link] [comments]  |

| How lethal is acute radiation sickness today, compared to 1986 ? Has anything changed? Posted: 20 May 2019 09:40 PM PDT Yeah yeah I'm watching the HBO show about the Chernobyl disaster. It made me wonder how ARS could affect us today compared to Chernobyl. Has there been any advances in medicine which could help mitigate the symptoms of ARS, and thus increasing survaivability? Are there better methods to treat patients today? I know the symptoms vary depending on the dose, but in general terms, has anything changed? [link] [comments]  |
| How do vaginal microbes affect twins at birth? Posted: 20 May 2019 09:43 PM PDT When twins are born by natural parturition, usually the firstborn will get more vaginal microbes than the second child as the first child takes most of it. 1.Does this create any difference in their later life?
