| Why is most of Earth's land concentrated on one side of the globe? Posted: 13 Jul 2022 07:21 AM PDT The Pacific Ocean is so large compared to the Atlantic, so it seems like all of the continents are clustered together more than they should be. Is there any specific reason that they aren't more evenly spread out across the globe? Did some great geological event happen to make it that way, or is it essentially just "how it is"?

| Ask Anything Wednesday - Economics, Political Science, Linguistics, Anthropology Posted: 13 Jul 2022 07:00 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] |
| How do astronomers find the oldest sections of the sky to look at? Posted: 12 Jul 2022 08:07 PM PDT Obviously a lot of space related questions with the JWST doing it's thing, but i wanted to know how they find the ancient sections of space to analyze? Do they scan the entirety of space looking for super redshifted space, or are there areas of the sky that are known to be particularly old? [link] [comments] |
| Are rapid SARS-COV-2 tests still as reliable with the new lineages BA.4 and BA.5? Posted: 13 Jul 2022 05:00 AM PDT And how come the rapid test kits can still detect the antigen even though these new variants shows such affinity for immune evasion? Will we have to test for another antigen in the near future? Or is the antigen somehow better "protected" against mutations? [link] [comments] |
| Posted: 11 Jul 2022 11:42 PM PDT A friend and I were arguing about the color of a car. I said it was pink. He said it was purple. I'm not a native speaker of English, so I wondered if that had perhaps something to do with it - perhaps my mother tongue delimited pink and purple differently than English. But asking some Americans, I found out that actually the jury was split. This got me thinking... - Are some color boundaries fuzzier / more ambiguous than others? For instance, yellow might not be as contentious a color as others, but that is just my impression. - If some color boundaries are fuzzier than others, is that consistent across languages? For instance, is the boundary between green and blue always fuzzy? - Are there any biological bases for color definitions, anchored perhaps in color perception and processing? I realize that this question straddles many disciplines, so I flaired it with Psychology but it could as well have been linguistic, anthropological etc. [link] [comments] |

| Botany: What is the difference between elaiosomes and fruit? Posted: 13 Jul 2022 06:39 AM PDT Or are elaiosomes considered a type of fruit? And in that case, what defines them? Is it something structural or are they functionally defined by the relationship with ants? I just encountered the word for the first time, and I'm trying to put the information into the proper conceptual slot. The Wikipedia article is somewhat unclear and could use some revision, or at least more explanation in this regard. [link] [comments] |
| I need to know does each person's body has their own bioelectricity signature ? Posted: 13 Jul 2022 05:49 AM PDT Because each body have the same bioelectricity Or two different for each person like each person has different amount of electricity coursing through their body or or do the human body make different types of higher electricity in each person's body I just thought about it and I just want to see if my theory is true [link] [comments] |

| Posted: 12 Jul 2022 05:20 PM PDT I can't really get my head around the size of nebulas. They look like a cloud from far away but if we were inside one would it be huge distances between lights or particles or whatever is being photographed? Or would it look just like a cloud from inside, too? [link] [comments] |
| Does the preparation for a colonoscopy have any effect on the health of the gut biome? Posted: 12 Jul 2022 09:36 PM PDT |
| What is the solution they put biopsy samples in? Posted: 12 Jul 2022 06:48 PM PDT When they remove a piece of tissue, what is the solution in the specimen container to be sent to the lab? Oral/throat tissue. [link] [comments] |
| is there a limit on how far back in time we can see with a telescope? Posted: 13 Jul 2022 04:26 AM PDT I've heard about how the JWST allows us to see things that happened close to the start of the universe. I sort of understand how this works, but I was wondering if there is any sort of theoretical limit on how long ago something could have happened that we could see with the telescope? Are there things that are just gone from our ability to observe, or will we be able to see further back by looking in the right places with more and more powerful telescopes? [link] [comments] |

| What shape do air parcels take below the LCL? Posted: 13 Jul 2022 07:20 AM PDT Above the LCL clouds take on very recognizable structures, though their morphology can vary vastly based on their state. Given that, do we know what shapes saturated air parcels take on below the LCL, like at the bottom of a cumulonimbus' anvil? [link] [comments] |

| What determines a material's heat capacity? Why is water's so high? Posted: 12 Jul 2022 04:51 PM PDT This question came to me at 1:30AM in bed thinking about why we actually boil stuff in water: it has high heat capacity so it spreads the heat evenly and stays hot after we turn off the heat (or put out the fire) But yeah water seems like an unassuming molecule if that makes sense, what makes it able to take in so much energy before changing temperature? [link] [comments] |
| what does it mean for the universe to have a shape? Posted: 12 Jul 2022 11:35 PM PDT I've read different articles discussing theories of the shape of the universe but I can't wrap my mind around all of the jargon explaining what that means and why it's important to study. help!

| How Common Are New Stars From Stellar Collision In The Late Universe? Posted: 12 Jul 2022 09:11 PM PDT I have heard that in the late universe (Degenerate Era I believe, but unsure if the technical stellar formation puts it before this) a small number of stars will likely form through stellar collision. I've heard of direct mechanisms for this that are below the Chandrasekhar Limit using carbon or hydrogen black dwarfs and brown dwarfs and some using neutron star collisions releasing "degenerate gas" (I assume this is a form of degenerate matter?). My questions are, How common are these interactions expected to be? Is it likely to happen anywhere in the universe multiple times in sequence? And What are these stars expected to be like?

| How do "color filters" work with an infrared telescope like JWST? Posted: 13 Jul 2022 06:07 AM PDT The James Webb Space Telescope famously records infrared wavelengths to get better images because infrared light can penetrate dust and molecular clouds. The recent images that are released are stunning, but as with many space telescope images, they are false color. This is not a problem; it's still the real image, real data, and really beautiful, but while looking up how they do the false coloring this article references "color filters" that are required for the telescopes operation. Another article mentions blue, green, and red filters (this one is not from NASA, so I cannot verify it's validity). Blue, green, and red are visible wavelengths, so how do these filters work with an infrared camera? Thank you! [link] [comments] |
