Does Jupiter have a core?
>Inb4 no one knows
What are /sci/'s thoughts? How is it held together if no core

i thought the astrophysical models predicted it had a solid core, actually.

not an astrophysicist but i remember someone mentioning metallic hydrogen. and metallic hydrogen sounds friggin sweet.

Plot twist:
It's actually Zeus encased in the sphere while swirling the entire thing in a circle to sleep or keep occupied.

I've seen the solid core theorized but theres also some theories that say there is no core and that the metallic hydrogen is in a gaseous state like the rest of the planet

Even without a core the mass of Jupiter is over 300 times that of Earth so its gravity would hold it together just like it does right now.

Metallic Hydrogen, Hydrogen gas under so much pressure it becomes metal

Gravity is sufficient explanation.

>> No.9990673

how do we know it's not just a hollow painted balloon?

>> No.9990719

>>9990673
Because that would not have enough of a gravitational field to keep the Galilean moons in place.

>> No.9990748

>>9990719
what if the balloon is filled with dark matter?

>> No.9990877

>>9990748
That would fail the Occam's Razor test.

Yes

>> No.9991029

>>9990748
then the dark matter would pass right out of the balloon, since dark matter doesn't interact with ordinary matter like balloons

>> No.9992003

>>9987764
It has a core with enough mass to have the gravity necessary to hold onto hydrogen/helium.

what if there is a material that interacts with dark matter in one direction and regular the other? Or depending on temperature, pressure or radiation?

so /sci/, when in the future will it become desirable or profitable to do large scale missions to jupiter, and what is a hypothetical timeline for it?

like e.g. would it ever be foreseeable that it could be used as a source of raw materials, like e.g. hydrogen isotopes for use in a non-terrestrial fusion power plant?

That would violate rotational invariance.
