What happens to human remains in shipwrecked submarines?

Posted: 11 Nov 2019 05:01 PM PST

The discovery of the USS Grayback prompted me to wonder: what happens to human remains in shipwrecked submarines?

First, is it necessarily true that all compartments of a submarine flood if it wrecks? If so, I would assume normal ocean decomposition.

If there are air pockets, what happens to the bodies of the crew in those compartments? Are the microbes we live with capable of consuming our entire bodies? Would they eat only soft tissue? Would the bodies mummify?

As Voyager is outside of the solar system, what is it's trajectory in the galaxy?

Posted: 11 Nov 2019 05:42 PM PST

What is the future of voyager in millions and billions of years?
Will it continue to orbit the galaxy if it doesn't hit anything in that period?
How much will its orbit drift from the sun's? Is it possible that it could crash into a planet one day?

do black holes form instantly? what is between a neutron star and a black hole

Posted: 12 Nov 2019 02:43 AM PST

for example if you could watch a super massive star in super slow motion explode would you be able to see the black hole forming or it would happen in an instant?

In tRNA, they group the nitrogenous bases into codons which depict the amino acid that they correspond to. Why do some codon combinations correspond to only one amino acid?

Posted: 12 Nov 2019 05:37 AM PST

I tried googling but to no avail. An example of my question is GGX, where X can be any nitrogenous base, why do they all still correspond to the same amino acid?

Why does removing some of the metal from the frame of a switch change the maximum wattage it can handle?

Posted: 12 Nov 2019 05:18 AM PST

I've been installing Lutron Caseta switches in my home recently and I noticed that in order to install 2 (or 3) in a single box, you have to remove these metal tabs from the sides that will be touching. The installation guide (see step 3 here: https://www.casetawireless.com/documents/QuickStartCasetaInWallDimmerUS.pdf) warns that removing these tabs reduces the maximum wattage rating of the switch. Why would removing metal from the frame - which will hopefully never have a current going through it - affect how much wattage the switch can handle?

Why is the Ferrel cell not rotating like the Hadley and Polar cells?

Posted: 12 Nov 2019 04:49 AM PST

Hello,

Why is air rising in the high latitude and sinking in the lower ones?

For the two other cells, it seems logical that the air rise as it is warming while going towards the equator but I don't get why the Ferrel cell is doing the opposite.

Thanks for your answers!

Can we model how humans forget things?

Posted: 12 Nov 2019 06:23 AM PST

I'm not 100% sure that this is the correct place to ask this question, but it should be a good place to start. I have a 2-year-old who currently speaks Chinese and English (I'm American, my wife is Chinese). We were living in Japan up until 10 months ago, so my daughter had exposure to Japanese and was able to produce/recognize Japanese. Now that we've been back in the states, she no longer produces nor recognizes Japanese, and this caused me to wonder how exactly the human brain goes about forgetting things. I'm not exactly interested in the mechanism of forgetting, but I am wondering if it's a statistical process. A baby needs to quickly learn which stimuli are important and which are unimportant. Therefore, while we were in Japan and she was hearing Japanese every day, Japanese words were deemed important because they had a high statistical frequency. Now that we're in the states and no one speaks Japanese, the signal strength of Japanese decays to a point that it is no longer deemed important. Is this intuition correct? I've tried looking for papers, but I have only succeeded in finding hand-wringing parenting forums. Any information is appreciated!

How does soy sauce get its black colour? I have heard that its because of millard reactions, but can someone explain in detail about the mechanism at such low temps?

How long ago is the Earth's Uranium thought to have been formed, and given its half-life, how much Uranium did there used to be around?

Posted: 11 Nov 2019 06:17 PM PST

I've been learning about how heavy elements form from neutron star collisions (is that right?), and that Uranium is the heaviest naturally occurring element on Earth, and it got me thinking about how much of it there used to be because it does decay and it had to have been formed a long time ago. I'd love to know what more we know about this. Thanks!

If Venus is hotter than Mercury why haven’t we explored Mercury more?

Posted: 11 Nov 2019 04:10 PM PST

If my research is correct it looks like we've only sent two probes to come close to Mercury and no landings. But we've landed on Venus. What's stopping us from going to Mercury?

Is there a consensus on what is a dinosaur? How different were they from dinosauromorphs ?

In the same way you bring in your arms while spinning, you spin faster, do things pulled in by gravity orbit faster?

Posted: 11 Nov 2019 05:34 PM PST

I was thinking about solar systems formation just after the sun formed. All that gasseous matter being pulled in to add to the suns mass and what stops it all from joining with the great bright ball.

So if that gas isn't going fast enough to yet, is it possible that it speeds up its orbit as it gets pulled closer to the sun, in a way that gives it orbital speed?

Would death by nuclear explosion be painful? How painful?

Posted: 11 Nov 2019 02:53 PM PST

Let's say I'm in Washington DC. Kim or Putin drops a nuclear weapon right in the center. If I'm anywhere inside DC, how painful would my death be?

While searching for Planet 9, why haven't ENA probes, sky surveys or big data analysis been able to locate Planet 9?

Posted: 11 Nov 2019 08:02 PM PST

ENA surveys should be able to identify a gas giant lurking there (a magnetic field would be required to prevent the solar wind from stripping the atmosphere). Sky surveys should be able to exploit gravitational microlensing's property of always increasing apparent brightness. And big data analysis should be able to solve for position based on the effects on astronomical bodies that has been observed. What makes it so difficult to find planet 9?

What is the difference between a dwarf planet and a protoplanet?

Every fuel on the market claims to have an additive that cleans and protects fuel injectors. Are we at the point where we would never have to buy fuel injector cleaner? Do these additives really do anything or are they just marketing?

Why is Patagonia dry?

Posted: 11 Nov 2019 08:02 PM PST

Well, it's on an east coast so it should be like China or the Atlantics... yet the temperatures are moderate and the precipitation is very low. It's like the Atlantic Ocean isn't influencing at all and all possible humidity must come from the Pacific, and gets blocked by the Andes. Why this is happening?

Thanks for the answers!
