Oh yeah, a magnet like that would kill you in so many ways, so fast. Of course it would rip the iron out of your blood, but that's child's play in the ways you'd died. Your neurons would become polarized and unable to fire. The cells in your body would all magnetize, ceasing any and all functions. You're toast.

I wonder if someone could set up an experiment to expose NaCl to an alpha flux (so simulated solar wind) and see how it changes the sublimation rate even at lower temperatures.

> the properties we expect of a metal, for example, actually depend on the atoms being cool enough to stick together.[...] But since hydrogen and helium are so much lighter than other elements they will still have different behaviour at such temperatures

Hey, that makes sense, thanks for the explanation. I've kinda wondered why they use the terminology myself since I learned it. My specialty is organic chemistry.

That’s pretty wild! Like we’ve all heard from Sagan that we’re made of star dust, but I never really thought I ought to be emphasizing the dust part much!

I’ve got a whole bunch more questions, but I’ll spare you—you’ve been more than patient enough.

Cheers

Would a magnet that size have any impact on the iron in our blood?

This discussion here answers this.

Actually not all flying insects have a specific number of stages. There are species, where the number of larval instars vary. Anyway, none moults after metamorphosis to the flying form.

Less likely, yes. Exponentially less, no. You'd be roughly right if molecule formation was just a matter of random chance associations, which is true in the diffuse ISM, but it is not true in dense clouds where molecules form. A large fraction of all molecules form in clouds that get cold enough that the molecules stick to the surfaces of solid (dust) particles. Once they're there, they're in rich company: there's hydrogen, carbon, oxygen, etc. in abundance - and then more "normal" chemical processes (i.e., things you might find happening on Earth) start to take over. So yes, the numbers game starts to reverse pretty hard!

Purely from gas-phase processes, though, you're basically right; we expect that most molecules with >5 atoms rarely form in the gas phase. We usually draw the line at methanol, CH_3OH, which is a bottleneck in the formation of more complex molecules.

It helps to think of how you'd actually send information via crossing two long sticks. Any method you actually come up with, will end up taking longer than just shining a light at someone.

What are the potential implications of supersymmetry for our understanding of string theory? Is it possible to prove supersymmetry?

Mostly.

That strong of a magnet would actually probably magnetize the rubber ball. Every material magnetizes under a strong enough magnetic field, but without knowing the specifics, it would be hard to calculate the effects.

Earthquake swarm at Yellowstone this morning. Magma on the move?

Thanks, That make sense considering how short lived house flies are

Would it ever be possible to 'mine' the Sun for Helium?

I've read articles that we are running out, which is worrying as I know that many machines/processes use different forms of helium.

While waiting for a proper expert to weigh in, I was curious about the same thing some time ago. This Nova piece on 'Absolute Hot' was interesting. Caution: like all things incredibly big or small, it's a tough thing to put perspective to from a human point of view.

Its pretty cool you know so much! (Being serious). I have done most of my searching using youtube/google searchs/and wikipedia (I know it gets a lot of crap but its a decent non acedemic resource)). What I meant about its composition is that it isn't uniform, what the composition in one area may be completely different in another area. We havent even been able to get samples from the mantle yet (Apart from lava) even the Kola super deep borehole is 12,262 meters, the crust is 40 kilometers. On top of that, we know that the magnetic field and even gravity is different in different parts of the world, which would indicate that composition and density varies. Scishow on youtube just did a cool short about mantle blobs on a side note.

On the subject of gravity creation devices as described by Bob Lazar - what's your take on it? Is it theoretically possible? Has anyone in science fiction developed a probable design for such a device?

I certainly don't know this bit, but I would assume that more complex molecules (which from what you're saying we know less about) are exponentially less likely. I say this mostly because the probability of finding element 1 and element 2 at some point in the universe is certainly less than the probability of finding just 1 or just 2. So, once you've dealt with all the combinations of two or three, whatever's left is unlikely to severely tilt the scales, unless that numbers game really reverses under some conditions. But, I take your point that if we can't describe larger molecules well, it's hard to say whether something more has its finger on the scale. Thanks for the answers!

I am interested in Gravitational physics, Astrophysics, theory of relativity and String theory and i wanna work on one of these topics for my phd. I'm a first year masters student and i wanted to do a project / write a review paper on one of the following to get a head start but I'm confused where to start. Any ideas on specific topics where I can start reading before I decide on a particular topic?

is the Physics they talk about on The big bang theory tv show real Physics, or is it made up?

what is required for mankind to harness and store energy from hurricanes?
