| Ask Anything Wednesday - Physics, Astronomy, Earth and Planetary Science Posted: 04 Mar 2020 07:08 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: 03 Mar 2020 07:39 PM PST I'm an archaeologist working on a 20th century site. We find a decent amount of early plastics, especially in the form of buttons, combs, and other items of personal adornment. The main way of identifying these plastics and synthetics such as caesin, bakelite, vegetable ivory, celluloid, and hard rubber is by scent after being heated. You generally only have to heat them up under hot water or rubbing between your hands - not super hot. However, this has been impossible to do with plastics we find archaeologically because they all just smell like dirt when heated, even after being well cleaned. Why does being buried in the ground for 70-100 years change the smell of these early plastics? [link] [comments]  |

| what prevents the cell from getting too large? Posted: 03 Mar 2020 07:55 PM PST is it the surface area to volume ratio gets too big so that the cell doesn't diffuse enough oxygen, or is it that when it gets too large the harmful toxins take longer to diffuse because the distance from the surface is increased?

| Does the Earth gets bigger trough the Seafloor Spraeading ? Posted: 04 Mar 2020 04:44 AM PST Today in school we learned sth about plate tectonics and the seafloor spreading. But does the Area of the earth gets bigger because of the Seafloor Spreading ? (srry for my bad English) [link] [comments]  |

| Can I crouch faster than gravity? Posted: 03 Mar 2020 06:39 AM PST Can I crouch or duck, faster than an object falls, with both feet planted on the ground, and not holding anything? [link] [comments]  |
| Can knots/overlaps occur between the strands of a b-sheet? Posted: 03 Mar 2020 01:51 PM PST I commonly see b-sheets illustrated through simple, linear examples like this one. Would it be possible for the bottom strand to somehow pass between the first two? Would this still be considered a b-sheet? [link] [comments]  |
| Why does soap lose it's bubbles? Posted: 03 Mar 2020 08:23 AM PST I'm doing the dishes. The concentration of soap:water doesn't change, just time/agitation of the water due to the washing of dishes. Why do the suds go away? Isn't there the same amount of soap to have bubbles with?

| How long before landing on the Moon did we know what it's really like there? Posted: 02 Mar 2020 11:35 PM PST When did we (as humans) know that it's just a "desert wasteland", and that there is no life there? [link] [comments]  |
| What is the organism with the largest AVERAGE cell volume, excluding single-celled organisms? Posted: 03 Mar 2020 10:35 AM PST I'm not looking for an answer the internet gives you like "ah yes the whale shark egg cell" or "check out this big egg-looking single celled fungus." Boring. I want to know which multicellular organism, if I took a tissue sample, has the largest average cellular volume. Basically which organisms, if viewed under a microscope, would require the least magnification to make out individual cells. I'm aware that generally, organisms have shockingly similar cell sizes. Despite that, this question still seems like it would have a satisfying answer. [link] [comments]  |
