| Is teleportation actually a thing, or is it science fiction? Posted: 30 Dec 2020 02:16 AM PST A friend of mine told me the other day that "they" (he didn't specify who "they" were) able to teleport "particles" (again, he did not specify what exactly) from the east coast of the US to the west coast of the US. I want to believe him but I haven't been able to find solid information on it that I can believe to be true. So my question is, has teleportation been achieved and or is it truly possible or is it more or less science fiction still? [link] [comments]  |
| How did we come to detect the new, more contagious variant of Covid-19 in the US (Colorado) ? Posted: 30 Dec 2020 05:27 AM PST The patient in Colorado is a male in his 20'a who has NOT traveled out of the country recently. This implies he contracted the new strain somewhere domestically & that the virus made it's way here undetected. How did we detect this new variant if the presentation is the same as normal Covid? How did anyone know to do genetic sequencing of that patient's virus? [link] [comments]  |

| Why can you still infect others with covid-19 after vaccination? Posted: 30 Dec 2020 03:14 AM PST I always thought that after having had a vaccine and developed antibodies, your immune system is so efficient at getting rid of the virus that it can't be spread to others. For example, if you had a successful chicken pox vaccine with formation of sufficient quantity of antibodies, you will no longer be contagious even when the virus enters your body. I thought that was the main reason why chicken pox is relatively rare now and how herd immunity works. Otherwise, chicken pox would be just as common, just milder. Is that wrong? Are you still contagious after vaccinations in general, you just get much milder or no symptoms? Are you less contagious but still contagious? Does it depend on the concentration of antibodies at the time of encountering the virus? Or is being contagious after vaccination a covid specific phenomenon? [link] [comments]  |
| Earthquakes are devastating to human civilization; is it the same for nature? Posted: 30 Dec 2020 03:53 AM PST Watching the recent videos of earthquakes in Croatia, and older footage of the Paloma earthquakes made me think of how anthropocentric this perspective is. When the world was covered in forests and an earthquake shook the land, what happened? [link] [comments]  |
| Why doesn't the orbital period of Saturn match what the math predicts? Posted: 29 Dec 2020 11:37 AM PST The orbital period of two masses orbiting each other is supposed to be where a is the semimajor axis of the orbit and M and m are the masses of the two bodies. If I plug in the values for Saturn and the Sun (a = 1.43353 * 1012 m, M = 1.9885 * 1030 kg, m = 5.6834 * 1026, the result is This is several months away from the actual period, which is 10,759 days. Where is the error in my math? Or are there other factors not captured by Kepler's Third Law? I'm trying to write a virtual planetarium using the recent great conjunction as a test case, and I suspect this is a source of error. [link] [comments]  |
| Would vaccinating the entire US population with one dose first be of any benefit? Posted: 30 Dec 2020 06:23 AM PST It seems that right now - and I could be wrong about this - the priority for the US is to get vulnerable populations such as health care workers, older people and people with preexisting conditions vaccinated with both doses of the vaccine before the rest of the general population gets one dose. This means that we can only use the vaccine on half as many people as we have doses. If we instead decide to prioritize vaccinating everyone with the one dose first, and then cycle back around to the ones who need it most for the second dose, would this give us any benefit? Do people build up any sort of significant immunity with just a single dose and could this start us on the path towards herd immunity? If so, how long does this immunity last? How long can we wait between the first and second dose of the vaccine? Could less vulnerable people need only one dose all together? [link] [comments]  |
| How are skeletons dated, and is it accurate? Posted: 30 Dec 2020 01:39 AM PST I've recently had my eyes opened to the fact the cult I'm in is not so right after all. If there are skeletons from humans dating back further than the bible, how does this not straight up disprove Adam and Eve being the first people on earth? How are skeletons dated, and is it accurate? [link] [comments]  |
| Ask Anything Wednesday - Economics, Political Science, Linguistics, Anthropology Posted: 30 Dec 2020 07:00 AM PST 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]  |

| Why can our body build lifelong immunity against some viruses, but not against all? Posted: 30 Dec 2020 04:08 AM PST First things first, I don't even know if that statement above is fully accurate, I just asume it is because for example once you've had smallpox you're immune for life while other viruses need multiple vaccinations and for the coronavirus it's not clear yet how long the immunity lasts. There were cases of people being infected twice. But why is it that our bodies are able to build immunity against certain viruses for a lifetime, while for others it can't? Thanks for your time! :) [link] [comments]  |
| Was gold easier to find in the past? Posted: 30 Dec 2020 12:12 AM PST History tells us that ancient civilizations had hoards and hoards of gold, which seems odd considering their lack of modern mining capabilities. Was gold more easily found in the past? In the history of gold, there was surely some that was much more easily accessible, leaving only the increasingly less accessible to all future miners. Is that right? Like gold could have just been lying around at some point. Don't know if I'm even making sense lmao. [link] [comments]  |

| Is this understanding of Hawking radiation correct and if so why does it lead to mass loss? Posted: 30 Dec 2020 01:09 AM PST This is the way I understand HR at the moment, can someone explain if this is correct or incorrect and if it's correct then I have a follow up question. So in my understanding - all around us the vacuum energy produces virtual particle pairs of particles and antiparticles, let's say a pair of one electron and one positron. In ordinary spacetime the particle pair gets annihilated, however at the event horizon boundary at a quantum level, one of the particles falls in while the other particle escapes. So if an electron falls in a positron gets released, so instead of being a virtual particle it now becomes an actual particle. From a different perspective a black hole just emitted a positron and that's what Hawking radiation is. Is that right? If so I'm not understanding how this leads to mass loss. Doesn't the black just gain an electron? Didn't the universe just gain a positron? Isn't this just adding mass to both the universe and the balck hole? In any case it makes no sense to me so I probably got some part of it wrong, if anybody would be so kind as to correct this, thank you. [link] [comments]  |
| Posted: 29 Dec 2020 05:20 PM PST I've always wondered what they mean; Is there a 'maximum' number the viruses can reach? Do they apply to all viruses or just certain ones? Thanks. [link] [comments]  |
| How are new Covid-19 strains detected? Posted: 29 Dec 2020 02:02 PM PST With the new strain of Covid-19 now spreading, I'm wondering how is it detected? Is there a variation in a Covid test that would indicate a slightly different strain? Are all Covid tests being monitored for a new strain? Thanks in advanced! [link] [comments]  |
