What do physicists do in Antartica?

Posted: 08 Jun 2017 06:41 PM PDT

I understand that there is a scientific community down in Antartica. But to my underdtanding, the majority of the science that goes down down there is biology. I assume that every field has its place, as it does everywhere. But what tyoe of experimetation and research goes on for the physics community down in Antartica? And how large of a community?

How did the early space probe cameras get the correct focus?

Posted: 08 Jun 2017 11:36 PM PDT

Did they automatically adjust the focus of the images? How? Or are the distance large enough that it's not needed?

If there is an underground ocean 400-600 km deep down the earth, is it possible for it to contain life?

Posted: 09 Jun 2017 03:07 AM PDT

My guess the temperature will be from 800C to 2000C, but this is a hard thing to prove. And how far did scientists reach for life signs deep down the earth?

How would the CH-47 Chinook deal with anti-torque/main rotor loss?

Posted: 09 Jun 2017 08:28 AM PDT

Would they be able to auto-rotate to attempt an emergency landing? Or would the be like the MV-22b Osprey, and be unable to auto-rotate?

How does fire behave in zero gravity?

Posted: 09 Jun 2017 07:11 AM PDT

Besides the typical "flames are spherical in zero gravity", does fire expand, and if so, how and why? If you were to be in zero gravity with a flammable gas, and set fire to said gas, what would happen? Any other information worth mentioning would be appreciated as well

Why does a coin make the noise it does when flipped?

Posted: 09 Jun 2017 06:15 AM PDT

While I have an idea how this might work, I'm unsure if this is just due to the coin spinning or if it's from whatever initial friction applied from my finger

Why are pancakes round, and what's the role of gravity and surface tension in this?

Posted: 08 Jun 2017 04:49 PM PDT

I read the same short answer everywhere "Pancakes are round because gravity pulls on fluid uniformly. When batter hits the griddle from above, it gets tugged down into a circle" I'm not really convinced, so it would be really helpful if someone explains it in a clear way.

Do radionuclides react with neutrinos more often than stable isotopes?

From a point on the near-surface of the moon, what path would the Earth trace in the 'sky'?

Posted: 08 Jun 2017 12:46 PM PDT

The moon is tidaly locked with earth, so it shouldn't move too much in the sky, however due to procession and an imperfect orbit, I would expect a timelapse of Earth taken from the surface to 'move' at least little bit, perhaps tracing out an ellipse or figure-8 over time. Google didn't seem to have any answers.

Why don't we have a global electrical network?

Posted: 08 Jun 2017 06:28 PM PDT

I mean something like the internet, but for energy. Isn't it more economical to share generation resources? Especially considering the developments in transmission technology (e.g. HVDC).

Is there a cure or just a way to manage PTSD?

Posted: 08 Jun 2017 07:39 PM PDT

Ive been told that people can manage PTSD but cant actually heal it. I just want to know if this is true or if it is curable. If it is curable, how is it possible? If it's not, why not? I couldn't find anything about this in the research I did.

How much sound would an explosion produce in space, due to the gases released at high velocity which produce a pressure difference compared to vacuum? Would it be audible?

Posted: 08 Jun 2017 05:43 PM PDT

Also, let's set aside any biological problems with a human ear in a vacuum, and suppose this is a sturdy vacuum-resistant microphone. The key point is the ability of a pressure wave to produce detectable sound-frequency oscillations in a membrane. Whether there are enough dB to be theoretically perceived by a human would be good to know, though.

Why can I use my pancake as a stylus?

Is the energy in a collision of a photon with a surface conserved?

Posted: 08 Jun 2017 10:15 PM PDT

If a photon were to reflect off of a hard surface like a mirror in the opposite direction would the wavelength be longer because it lost energy or would the energy be the same? Like if a color, for example blue, were reflected in a mirror would the image in the mirror be a little redder than the actual material? Thanks, Greasejunkie

Why do rotor blades or fidget spinners seem to spin the other way when they spin too fast?

Death - what is it and what happens after?

Posted: 08 Jun 2017 04:02 PM PDT

Hello late night science-lovers,

Sometimes when I watch science programs, interviews, etc. about death I get this empty feeling inside when picturing total blackout for eternity after death. As a believer in science and as an atheist I'm sure that would be the way to picture it. Or am I wrong? I wouldn't say I'm afraid of death itself, I'm just really afraid of what comes after - or the lack thereof, I guess.

Are you afraid of death? And how do you picture everything post-death? Is there even any proof of anything related to death? (Besides all the hoax stories and the fact that we all will experience it at some point).

Thank you in advance!

Note: I realize this question is kind of edgy and out there, but I hope you understand what I'm trying to express.

EDIT 1: Just want to clarify that I'm not - in any way - looking for comfort haha. Just want to ask people with a flair for science what their opinion is on death.

EDIT 2: Grammar :/

Exhaust pressure for maximum specific impulse?

Posted: 08 Jun 2017 11:40 AM PDT

I heard that rocket nozzles are made in a way, so that the exhaust has the same denisty as the surrounding space.

But wouldn't you get the most thrust if you would shoot out the exhaust as straight as possible?

Why does the mass of the Higgs Boson indicate it is metastable?

Posted: 08 Jun 2017 08:45 AM PDT

Also, from what I understand a vacuum state in field theory is when a quantum state is in its lowest possible energy. Wikipedia says this generally means it contains no physical particles. Would this not imply that every other fields such as the electron, gluon, quark, z boson, photon field etc etc be metastable as well? I'm just somewhat confused.
