| How does Europa have liquid water? Posted: 01 Oct 2021 05:41 AM PDT I've always understood the habitable zone to be the only distance where liquid water could exist on a planet. Any closer and it would evaporate, any further and it would freeze. The habitable zone for our sun is 0.9 - 1.5 au, yet Jupiter is 5.2 au on average from the sun with the closest distance being 4.95 au. So how would liquid water be able to exist so far outside (over 3x the furthest distance of the habitable zone)? Is the habitable zone as we currently know it just kind of bs? [link] [comments]  |
| Posted: 30 Sep 2021 11:24 AM PDT My college has mandatory vaccine & masks, but as expected, there are some students still getting sick. Constantly moving through hallways, I'm potentially (or even likely) being exposed to at least some of the virus. Is there any chance that I'm going to develop super immunity to covid from long term, (hopefully)low level exposure? Or, to get to the meat of the curiosity, in what circumstances would this/would this not happen with any virus? What is known about the characteristics of such a scenario? [link] [comments]  |
| Posted: 30 Sep 2021 12:42 PM PDT I have a high school level biological sciences education and have studied mostly computer science since then. I'm given to understand that some people can be asymptomatic carriers of viruses and I want to understand how this works. From what I understand,
But I also thought,
So, how does this work? Am I still carrying the influenza variant from the last time I got the flu? I am not currently sick with the flu. Could I spread it to someone who is not immune to that variant? Or did my body completely get rid of that virus? [link] [comments]  |
| Which of a nuclear explosion's effects are unique to it being nuclear? Posted: 01 Oct 2021 06:34 AM PDT Radiation and fallout are obviously due to the radioactive fuel source, but what about things like the flash or mushroom cloud? How many of, say, Little Boy's effects could be replicated with 12,000 tons of conventional explosives? [link] [comments]  |
| Posted: 01 Oct 2021 06:18 AM PDT I recently heard from Dr Tyson that all galaxies (or at least the vast majority, he wasn't being super precise in this presentation) we have checked appear to have black holes in their centers. That got me wondering why that would be, and this galaxy-scale accretion disk is the best idea I've got. But I feel like I would have heard of that before if the answer was that simple, and that doesn't really fit with the way that black holes are formed themselves. So what's the deal?

| How much truth or myth is there to the idea of laugh lines and scowl lines? Posted: 30 Sep 2021 03:45 PM PDT How much truth or myth is there to the idea of "laugh lines" and their counterpart scowl lines? Are there any good studies that look into the amount that laughing and smiling, or frowning and scowling, actually affect how and where wrinkles form on your face? I imagine itd be very difficult to carry out a proper study of this. [link] [comments]  |
| Posted: 30 Sep 2021 05:48 PM PDT Is an "earthquake" ultimately just powerful vibrations radiating from the fault line, followed by settling of sediment, or is it a more complex chain of events than that? [link] [comments]  |
| Will electrons switch places in an orbital? Does this even matter if electrons are identical? Posted: 30 Sep 2021 08:10 AM PDT To keep it easy, let's say you have a helium atom with just two electrons in the orbital. Will they ever swap spins? As in the one that is spin up will "switch" to spin down, while the other switches to spin up? Can you even tell if this happens if electrons are identical? [link] [comments]  |
| Can hyperthyroidism be caused by iodine supplementation? Posted: 30 Sep 2021 03:35 PM PDT I've tried researching this myself but the results from google are either horribly vague or conflict with eachother. Will >1100mcg of iodine per day trigger the Wolff-Chaikoff effect? And if so, would continuing iodine supplementation post-Wolff-Chaikoff cause an overproduction of thyroid hormone or will excess iodine be excreted? Or, would continuing iodine supplementation during the Wolff-Chaikoff effect result in hypothyroidism from not escaping the effect? Does the Jod-Basedow phenomenon factor in when there is no iodine deficiency involved? [link] [comments]  |

| What is the chemical reaction that produces the nitrogen oxides in diesel engines ? Posted: 30 Sep 2021 12:07 PM PDT Is the same amount of nitrogen oxides produced by a gasoline engine, for burning one liter (or gallon) of fuel ? [link] [comments]  |
| What is the mechanism of Uncanny Valley? Posted: 30 Sep 2021 11:58 AM PDT Have people before the advent of AI experienced this phenomenon? Are we likely to feel this way about our closest relatives-apes? [link] [comments]  |
| Posted: 30 Sep 2021 12:11 PM PDT Since childhood I was wondering how humans change direction/turn. [link] [comments]  |
| How much heat is released by a processor chip in regards to its consumption ? Posted: 30 Sep 2021 07:44 AM PDT If a processing chip consumes a given amount of energy, is it going to release as much in heat (minus deformation or chemical reaction and such) ? Or is the computation itself going to take up some of that energy ? [link] [comments]  |
| How many people were vaccinated against small pox? Posted: 30 Sep 2021 07:40 AM PDT I can't seem to find any info regarding the number of people that were vaccinated against small pox. I did some searches on the net but cannot find anything. I don't know where to look. [link] [comments]  |

| How does the body recognize disease? Posted: 30 Sep 2021 04:58 AM PDT The answer I'm getting is that it doesn't recognize whatever is on the surface of the virus or bacteria, but we're immunizing people with a single isolated protein. How does your body know that's it's hazardous? Will you body develop an immunity to ANYTHING (protein shaped) that's in your blood long enough? [link] [comments]  |
