That is insane. Awesome.

[count2infinity]

That's pretty cool.

if you add the volume of the other 8 planets (PLUTO IS STILL A PLANET TO ME, DAMNIT!) they would still not have as big of a volume as Jupiter.

RIP Frederick Sanger... It's very rare to see a two time Nobel laureate.

I wonder what the most dense planet is.

Earth>Mercury>Venus>Mars>Pluto>Neptune>Jupiter>Uranus>Saturn

Earth would float on Saturn...

[Rylan]

That's awesome. Is there an actual surface on Jupiter, Uranus, and Saturn or is it just assumed since we can't see past their atmospheres?

Also, I am surprised to see Venus is denser than Mars.

[MRandall25]

The gas giants don't have a surface because they're made of gases...

You can use spectral analysis to have a pretty decent idea of what makes the planet (as far as atomic percentages go...). Based on that, it's mostly speculation as far as how it's distributed and in what form (solid, liquid, gas). Some speculate that the core of Jupiter has enough gravitational pull on it to actually be comprised of metallic hydrogen, which if someone could ever make on Earth, they would be given the Nobel Prize right then and there.

I have done spectral analysis of cosmic gases, it was pretty cool (spent three days in Greenbank, WV).

Metallic hydrogen? How does that happen, an isotope or just extreme pressure?

Well, if you look on the periodic table below hydrogen, there's reactive alkali metals. The theory is that if you put enough pressure on hydrogen gas, it'll become a liquid or a solid. What would it liquefy or solidify into is the question. A lot of theorist believe that it'll condense into a metallic phase with enough pressure. Also, that metal (again, theory) would be a superconductive metal, and many people think that's what's responsible for Jupiter's outrageous magnetic field.

[columbia]

How much energy would it require to do that?

to

put enough pressure on hydrogen gas

and yield said metallic hydrogen.

It's heavily disputed in the literature. One person rushed out and claimed they made it, others repeated his experiments and found no evidence of metallic hydrogen. So as of right now, I'd say no one knows. What's really cool is the calculations suggest that it would likely be a superconductor at room temperature, which is one of the big draw backs to superconductors today, they have to be super cold to work... metallic hydrogen would require no cooling to work.

[Grunthy]

I'm pretty sure we already have liquid hydrogen, its the metallic that has yet to be discovered.

[count2infinity]

very true. You'd need to then compress it enough to the point where the bond between they hydrogen atoms becomes delocalized like a metal.

I wish I was smart enough to make it and become a billionaire, lol.

To quote my boss... never has there been so much work toward something that will likely yield so little results. Even if you can make it, then you need to figure out a use for it and I don't necessarily see how something that only exists in such super harsh conditions would be applicable to anything in the real world. Who knows, it may, but I doubt it.

Looks like Ison broke up..Disappointing
