....................................................................................................... I just hope these guys got the science right and their research doesn't turn out to be another boob job.

There must be venting in the Hollywood, CA area

Don't get your hopes up ...

... 85% iron and 10% nickel ... “Our latest experiments suggest that the remaining five percent of the inner core is composed mostly of silicon,” Ohtani said. ...

... doesn't sound real inviting ...

The key word is "composed". Like you are after seven Asahi beers. Maybe some bubbling. Funny thing is whenever I experience silicon in real life, the last thing I am is "composed". Ah, Summer Brielle. Science. Always clean with no bad aftertaste. Try some today.

Silicon is not silicone.

It's the San Fernando Valley that's Silicone Valley ...

The Earth is believed to be made up of three main layers

The core comprises an outer layer of liquid iron and nickel, and an inner layer

Um, that makes four layers, Google image search and many have four, with some dividing the mantle into two distinct layers, making a total of five.
