- Register for Keynote Address by Prof. Alex Wellerstein, "The Atomic Bomb and Visions of the New Post War Order"! Live at 1 PM ET, 9/15 as part of the AskHistorians 2020 Digital Conference.
- Does other viral respiratory illnesses like common cold or influenza also cause long lasting cardiopulmonary or neurological sequelae like COVID-19 is doing?
- Does gravity increase or decrease as you get closer to the core?
- When did sunburns become common? Are they a result of relatively recent climate changes or are UV Rays something that humans have always had to contend with?
- Does hand sanitiser use make pathogens more hand sanitiser resistant, in the same way antibiotic use does?
- What is the hospitalization rate for people who contract coronavirus?
- When the NASA Probe "Cassini" made to Saturn, it was put in an elliptical orbit that passed between the planet and it's ring over and over again. How does NASA send a probe and have it go such a specific course so precisely?
- i know there isn't STRONG evidence for the quark star theory in the first place, but what makes it even considerable?
- Is it possible to know long after-the-fact if a person ever had CoViD-19, even if they were largely asymptomatic and never got tested while they were an active case?
- Is air brought in through the nose cleaner than air brought in through the mouth?
- Anthropologists, what did our ancestors (both recent and modern) use as diapers for their children?
- Question about CO2 absorbing IR light?
- How is it possible to filter out all the waste, drugs, and bodily fluids that end up being flushed down the toilet, and come out with such clean potable water?
- Is the Higgs Boson the only scalar boson that exists, or is there a possibility of another?
- How is liquid breathing advantageous over air breathing for divers?
- Will the American West lose its boreal forests?
- How exactly does a flu vaccine work?
- Why do humans seem to have an affinity for symmetry in almost everything, and do we share this affinity with other animals?
- Was the spanish flu worse in the winter than all other seasons?

This event is coordinated by our friends at /r/AskHistorians, but given the overlap of the keynote address with the sciences, we thought the readers of /r/AskScience would be interested. This thread is just an announcement of the event, so comments will be locked here. If you're interested in attending the event (via Zoom), fill out the registration form above. [link] [comments]  |

| Does gravity increase or decrease as you get closer to the core? Posted: 12 Sep 2020 06:14 AM PDT Say you were to dig a hole down 75% through the mantle and stood there (assuming you had some special suit for the heat). Would there be more or less gravitational force? There would be less mass below you but you would be closer to the dense core. Also, would atmospheric pressure be much greater in the hole?

| Posted: 11 Sep 2020 03:04 PM PDT While absolutely necessary at the moment, seeing hand sanitiser everywhere had got me thinking. We have really overused antibiotics, creating a new problem for ourselves with antibiotic resistant pathogens, is there a chance we are in the process of doing the same with hand sanitisers?

| What is the hospitalization rate for people who contract coronavirus? Posted: 11 Sep 2020 10:13 PM PDT I've found it difficult to track down what seems an important statistic: if you contract the coronavirus, what are your odds (on average, or by age, etc.) of getting so sick you need hospitalization?

| Posted: 11 Sep 2020 11:59 PM PDT How do they achieve this sending an object to something so far away? [link] [comments]  |
| Posted: 11 Sep 2020 07:43 PM PDT so from what I (hopefully) understand, what keeps a neutron star from collapsing in on itself is the neutron degeneracy pressure, and once the star absorbs too much mass, its gravitational pull overpowers the neutron degeneracy and it collapses into a black hole. or, theoretically, it could become a quark star, but I don't understand how that would work? if the star collapsed to the point where the neutrons broke down into quarks, how would it not just continue collapsing? I feel like the way that I'm trying to picture that process is all wrong lol also, I thought quarks were so small that they essentially take up zero space? I hope this doesn't sound silly, but how could quarks alone even make up something of substance if they don't take up space? also im sorry in advance!! I'm a junior in high-school so my knowledge on advanced physics is just based off doing research on the internet, i wouldn't be surprised if im not understanding something correctly :p [link] [comments]  |
| Posted: 11 Sep 2020 08:19 PM PDT Are there any lingering indications that can be detected, even if they were a very mild case? [link] [comments]  |
| Is air brought in through the nose cleaner than air brought in through the mouth? Posted: 11 Sep 2020 07:33 PM PDT |
| Anthropologists, what did our ancestors (both recent and modern) use as diapers for their children? Posted: 11 Sep 2020 06:36 PM PDT |
| Question about CO2 absorbing IR light? Posted: 11 Sep 2020 08:55 AM PDT I was trying to understand the greenhouse effect more, and know that the Infrared light gets absorbed by greenhouse gases due to their vibration modes corresponding to frequencies of light that fall in the IR range. My question is, are these vibrations the result of the electrons in the molecular bonds becoming excited, and the manifestation of that excitement appears as the atoms in the molecule vibrating about? Or is it the atoms themselves absorbing the photons, causing them to have more kinetic energy, and those vibrate around a center of mass? Furthermore, if a molecule of CO2 absorbs an IR photon and it's vibrational modes begin moving faster, shouldn't the molecule be able to aborb photons of higher and higher frequencies of light that correspond to faster and faster vibrational modes, until the molecule eventually gets ripped apart? I know this does not really happen, but do not understand why. Sorry if this was really poorly worded. [link] [comments]  |
| Posted: 11 Sep 2020 10:10 AM PDT There's so many things that people throw down the drain and toilet like food, human waste, drugs; I guess the simple answer is filters, but how strong of filters or counter chemicals do we need to have in order to squeeze out clean water? [link] [comments]  |
| Is the Higgs Boson the only scalar boson that exists, or is there a possibility of another? Posted: 11 Sep 2020 10:00 AM PDT |
| How is liquid breathing advantageous over air breathing for divers? Posted: 11 Sep 2020 04:56 PM PDT Does it have something to do with saturation of nitrogen or helium in the tissues? How does it prevent the adverse effects of gaseous toxicity experienced by saturation divers? [link] [comments]  |
| Will the American West lose its boreal forests? Posted: 11 Sep 2020 10:52 AM PDT |
| How exactly does a flu vaccine work? Posted: 11 Sep 2020 03:56 PM PDT I know it has an inactivated form of the virus and that causes an immune response, however, I want to know the specifics of exactly how it works. From creation to immunity. Don't hold back, I am a Biology major so I'd like to think I can understand. [link] [comments]  |
