Hmm... if by "planetary ecocide" you mean "rip out half the planet and leave the other with a huge hole in it" then sure, it's planetary ecocide...

Hence my "many times over".

Gas Giants are actually theorized to have a solid core, usually of a few earth masses at least (that's why you get that many super-earths close to stars... gas giant forms, migrates inwards and gets its gas blown away).

So, let's just say, any object that should cross through a gas giant does also have to be able to pass through earth... Passing through earth should actually beeasier, since the solid crust is pretty thin, and from there on in you have liquids with a lot less pressure than in the lower atmosphere of jupiter...

Whatever substance is inside Jupiter can survive being inside it... that's why it's there. If no matter could survive being inside Jupiter then it's core is made up of only radiation :hmm:

following that logic, I might as well try to pass an object through a black hole...

 

[JEL]

Well, if Hawking-radiation is in fact true and exists as predicted, then all matter entering a black-hole eventually comes out of it again, right?

 

[jedidia]

I think that the OP presupposed that the object passing through the gas giant should still be recognizable afterwards...

Yes, but it's all superpressurised enigmatic high temperature high pressure allotropes at thousands of degrees, that you can't make a spacecraft out of...

(that's why you get that many super-earths close to stars... gas giant forms, migrates inwards and gets its gas blown away)

That's what is known as a [ame="http://en.wikipedia.org/wiki/Cthonian_planet"]Cthonian planet[/ame], and it's only really relevant to planets that are extremely close to the parent star. An example of a cthonian planet is COROT-7b.

Any matter would be able to exist there, only under extreme pressures. You can't crush matter into nothing.

Probably... but I wasn't

If the spacecraft was so dense that it formed its own black hole it would go through gas giant or star with little more difficulty than going through vacuum.

 

[N_Molson]

I'm not sure but can't some exoctic particles, especially [ame="http://en.wikipedia.org/wiki/Neutrino"]neutrinos[/ame], go through almost anything ? Of course it's not really matter, and those hardly have a mass...

For anything more "solid", the inner layers of the gas giants are supposed to be made of liquid-metallic hydrogen or methane, with maybe objects like giant diamond "icebergs" floating on the metal... It's hard to imagine something stronger than that...

You would have to be going really really fast for that. Since, even with black holes, conservation of momentum still applies. So you need to bring enough energy to accelerate everything you suck up.
Which will be rather hard given that afaik the only means of propelling a black hole is by gravitational attraction from outside masses.

I like the way you are thinking. I even like it more to be able to actually leave my spacecraft

 

[jedidia]

If the spacecraft was so dense that it formed its own black hole it would go through gas giant or star with little more difficulty than going through vacuum.

either that spacecraft would be so small that it could pass through an atom with a negligible chance of hitting a particle, in which case yes, it could go through. It just has to do so damn fast, because it will decay in a matter of seconds.

Otherwise, your black-hole vessel has a good chance of having a mass actually larger than the gas giant, and it would be a valid question who would pass through who.

In any case, there won't be a gas giant left after you passed through it. If you consider that mission accomplished, you're probably working in weapons research, not in astronomy...

Can something (an atom even?) quantum tunnel though a vast turbulent object like a gas giant?

AFAIK such quantum phenomenons don't occur in such a big scale. And quick look at wiki whould give you an answer that only single particles, not the whole atom can do that:thumbup:. Of course if quantum tunnelling is what you had in mind.

 

[Carmen A]

Suffice to say if a physical object were to attempt to fully penetrate a planet sized object to punch through the core and exit the other side, the planet would be in pieces, literally

Well, if you had a collection of some particles that, like neutrinos, don't interact via any known force except gravity, but do interact via one or more unknown forces, you could actually build a multi-particle object out of them, and they would be able to go through any normal matter.
