Someone brought up Jupiter in a conversation and it was because recent theories suggest that the core of Jupiter is a large diamond (carbon) pressurized to such a state by the many layers of different gases there. Is this at all possible?

There are also one or more theories that proport how Venus was separated out the a larger Jovian body. It is thought that this separated bit of Jupiter hit Mars before settling into its present orbit as Venus. Is this at all a possibility?

Thank you.

Actually we are just gaining the technology to understand what is going on at the centre of the giant planets in this solar system and outside of it.

If iron is the most abundant element judging the meteorites etc, and it's perceivable that molten iron seeps into the core of protoplanets, then why would the core of Jupiter not being dominated by iron, fluid and solidified just like the Earth core??

On to Venus.... is it Jupiter's little baby?

Instant criticism of this theory will not be taken seriously. Some of the sources that started the theory are admittedly questionable... for instance the old testament of the "bible".... some of the sources are as credible as any source such as ancient Iranian and Chinese astronomical records.

You can find out more about Velicovsky here

There is a good synopisis of his explainations here

I'm afraid I have to agree with AstrumAspicio, about the physical impossibility of Velikovsky's Jupiter - Venus construction. The impossibility for instance, of the planets having solid stable near circular orbits. If Venus had emerged from Jupiter, it potential energy was to be so big that it would have to be in a highly eccentric orbit around the sun, if it was orbitting at all. And if Venus would have had a close encouter with Earth (Wolds in collision) then Earths orbit would have been destabilized as well due to mutual gravity interaction.

Open mindness is a great thing, but you have to test your ideas against physics and reality. The proof is in the pudding.

Wow, that's quite something here.

I googled a bit that's a whole other world it seem

So we have anectdotal evidence that something weird happened to good old Earth. It skipped a day!? But how? Doing something with the rotational axis? Let's see if we can sciencify that (I love inventing new words).

So we have observations of long days, so what is the hypothesis? Earth slowed down rotation for a while?

I can see two serious problems with that, both pertaining inertia, the law of constant momentum, which doesn't allow for such a slowdown unless you flatten the earth tremendously but that's even weirder. Furthermore what would happen to the loose things on the earth surface and the atmosphere when it would decellerate from say 1000 miles per hour to a few hundred miles. The inertia would cause the atmosphere to continue spinning with the original speed, you would have a world wide storm of several hunderd miles per hour. Unlikely if there would have been survivors.

Considering the earth has an resonance cycle period of something like an hour, if you generate a force on one side of the earth, braking it then it would take an hour or someting before the other side would know about that force while continuing spinning at the original rate. That would cause a break up.

hate to spoil it, but it's rather impossible to find a physically sound mechanism that could cause the Earth temporarily reducing the spin for a day.

Of course there are other possibilities. Super nova? I don't know. main thing is, keep it scientific, observations, physically sound mechanism, test and attempt to refute. Joshuah's long day would not survive scrutiny.

But then again myths are not very accurate observations, are they?
