| Does a Corona virus actually look like a ball with spikes? Posted: 05 Jan 2021 05:09 PM PST Whenever the media needs to explain something about the corona virus, it is portrayed as a sphere with spikes on it. Does it actually resemble that look in reality or is that just a model and it looks completely different in reality? [link] [comments]  |

| Ask Anything Wednesday - Physics, Astronomy, Earth and Planetary Science Posted: 06 Jan 2021 07:00 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: 06 Jan 2021 03:12 AM PST So what my question comes down to is there a species that can kinda inbetween a virus and a prokaryotic cell? [link] [comments]  |
| Why solubility of a gas in a liquid is exothermic? Posted: 06 Jan 2021 07:57 AM PST The solubility of a gas in a liquid decreases with the increase in temperature.Why? Also, why is it an exothermic process? Thanks in advance! [link] [comments]  |

| Does a nuclear weapon detonating in a vacuum create the characteristic double flash? Posted: 05 Jan 2021 09:45 PM PST From what I've read, the shockwave of the nuclear detonation briefly obscures the light from the nuke, which creates the double flash used by satellites to verify an atmospheric nuclear test. But would a nuclear detonation in space cause the same effect? I did not see any mention of it for nuclear weapons tested in space. [link] [comments]  |
| Why won’t the rocket equation give the same answer for simple conservation of momentum? Posted: 05 Jan 2021 04:57 PM PST you know how the ideal rocket equation says Delta V = Vexh ln(m0/mf)? If I use it for a very simple example, like a bowling ball with an ice skater, I get two different result, and I don't know why. Here's what I mean: Say that a 50kg ice skater with a 10kg bowling ball launched the ball at 10 m/s in one direction. From the conservation of momentum, the ice skater should go 2 m/s in the other direction right? But if I plug that into the rocket equation (Vexh = 10 m/s, M0 = 60 kg, Mf = 50kg), I get like 1.82 m/s. Why is there a discrepancy? Isn't the derivation for the rocket equation just based off of conservation of momentum? [link] [comments]  |

| Posted: 05 Jan 2021 05:30 PM PST Given the relative widespread practices of mask-wearing and social distancing compared to previous years, is it possible to supress the spread of influenza to the point where it is no longer endemic? Here in the US, influenza cases are low across the country, even with massive amounts of people not following disease-preventing practices. I'm not a pathologist/virologist/epidemiologist but I had the thought that there may be an opportunity to capitalize on given the communicability of the flu is almost a magnitude lower than COVID, if not here in the states, possibly in other countries.

| How do black holes interact with expanding space and dark energy? Posted: 05 Jan 2021 11:23 AM PST I have two questions about the interactions of black holes with dark energy. 1) How does expanding space work inside black holes? Most are rather small so I would imagine that the effect is negligible but if we consider a black hole with a radius of 5 billion light years where the expansion of space would be significant. Would an object falling through such a black hole take a longer time to reach the singularity due to said expansion? Any noteworthy effects? 2) Additionally, can black holes grow in mass and size from dark energy? I've read that the density of dark energy is 7 *10-30 g/cm3, could there be a point where a black hole of sufficient size gains more energy from this than it loses due to hawking radiation and thus keeps growing forever?

| Will the Lateral Flow Antigen tests be able to detect the new strain of the coronavirus in the UK? Posted: 05 Jan 2021 10:35 PM PST As a science student at a university I'm currently working in an asymptomatic testing centre for COVID for experience. We started 2 days ago and having tested hundreds of people we have only had 1 test come back positive. Is there a chance that the tests cannot detect the new strain? What is the exact mechanism of the test? [link] [comments]  |
| Posted: 05 Jan 2021 09:15 AM PST Like is there any fish or mammal that wouldn't be able to survive if they just had a single source of food? [link] [comments]  |
| Is Lake Superior a failed rift, a product glaciation, or both? Posted: 05 Jan 2021 06:55 AM PST I'm not sure which one it is, as I've read in some places that all the Great Lakes were formed by glaciers in the Ice Age, and in other places I've read that Lake Superior fills a rift that almost tore apart Laurentia. I hope somebody can clarify this for me. [link] [comments]  |
