Top of the World Pt II


It is a natural instinct to seek the high ground. While we're looking at tall buildings, here's someone ready to give a girl a lift.
A well-known science blogger, normally considered a skeptic, just wrote one of the nicest things I've ever heard. "Start to advocate the nice Riofrio, a full-time researcher in cosmology who is suppressed by the sexist pigs in cosmology, despite having her "GM=tc^3" theory of the Cosmos that is far simpler, more important, and more testable than anything that (name removed) or any of his colleagues have ever invented during decades if not centuries of their fruitless and expensive efforts." I heard that he likes pictures of monkeys too.
Taiwan is vulnerable to both earthquakes and cyclones. On floors 87-89 of TAIPEI 101 is the world's largest wind damper, a metal ball weighing 660 tons! For all those in physics class studying damped oscillations, this is the perfect example.
We know that Earth is divided into core, mantle, and crust because a woman named Inge Lehmann studied the seismic waves recorded during earthquakes. These waves follow paths with names like PKP and SKS. By carefully recording the arrival times and locations, she calculated that they were refracted by discontinuities in Earth's depths. The easiest wave to detect should be PKJKP, a wave passing directly through Earth's centre and out the other side. Despite many searches, that wave has never been reliably detected. Something sucks it up!
Since we are not seismic waves and can't reach Earth's centre, we are in no danger of being eaten. The amount of materiel that is sucked up is barely what a human eats. (Earth gains much more materiel each year from meteorites.) That small diet, partially converted into Hawking radiation, has kept Earth's core hot for billions of years.

Hi Louise, I've changed your name from babe in the universe to riofriospacetime. Still thing you are a "babe" just that riofriospacetime is more you "you". Q

Beautiful and brainy. No no wonder the men feel threatened. They can't compete so they defend.

Thanks for stopping by my blog and answering my question. I figured there would have to be some sort of pressurization or folks wouldn't be enjoying that trip.

How I love heights. Unfortunately I don't see Taipei as being part of my near fututre. Because of that I thank you for sharing.

so does that mean there's a black hole in the center of the earth that sucks up seismic waves?

Good morning all. Q9, thanks for a good idea and everything else.
Quill, perhaps there are tall buildings near you that you've not visited. With your experience, you could find work teaching English in Taiwan.
Anon, good deduction. What else could suck up an earthquake? The lack of a PKIKP wave is almost a smoking gun.

Louise, you got people thinking. From Lubos' site. tu sabes quien.

What is about Riofrio? Just another variant of Dirac's Large Number Hypothesis, isn't it?
