Bob Bass, one of America’s best mathematicians over the last century, once redid Lord Kelvin’s heat equations for the Earth WITH a maximal upper bound figure for radioactive elements and any effects which any such could cause, and he got a figure of about 200M years.
Does anyone really think these guys can figure out the age of the Earth (or the solar system) to the next 100 million years?
100 million years in a span of 4.6 billion years, is about two percent.
Has anyone ever observed such clumping together? And what's this "dust" stuff? And "other material" too!? I thought it was all just a bunch of hydrogen (gas) to begin with. Why would hydrogen clump? What happened to PV=nRt?

It's nice to see someone at least address this idea of accretion. Most of what I've seen never seems to address a 6000 mile diameter earth and what might have been going on whenever it was 6000 miles in diameter.
As for biggies (among the unknowns) I guess I'd like to know how all that iron worked its way to the core.

Hey, dumbass reporter... 4.476 billion years old is NOT “much younger” than 4.576 billion years old.
That’s a difference of about 2%.
It’s like saying, “I’m not 60 years old. I’m MUCH YOUNGER than that. I’m only 58 years, 8 months old.
When you read a headline about the earth being MUCH YOUNGER than previously thought, you think, huh-oh, creation science time.
Neal Adams believes the Earth is STILL growing. His animation at http://www.youtube.com/watch?v=oJfBSc6e7QQ makes an interesting case for his theory.
Sorry, but this is all nonsense.

Excerpt:
Geology became established as a science in the middle to late 1700s. While some early geologists viewed the fossil-bearing rock layers as products of the Genesis Flood, one of the common ways in which most early geologists interpreted the earth was to look at present rates and processes and assume these rates and processes had acted over millions of years to produce the rocks they saw. For example, they might observe a river carrying sand to the ocean. They could measure how fast the sand was accumulating in the ocean and then apply these rates to a sandstone, roughly calculating how long it took sandstone to form.
Similar ideas could be applied to rates of erosion to determine how long it might take a canyon to form or a mountain range to be leveled. This type of thinking became known as uniformitarianism (the present is the key to the past) and was promoted by early geologists like James Hutton and Charles Lyell.
These early geologists were very influential in shaping the thinking of later biologists. For example, Charles Darwin, a good friend of Lyell, applied slow and gradual uniformitarian processes to biology and developed the theory of naturalistic evolution, which he published in the Origin of Species in 1859. Together, these early geologists and biologists used uniformitarian theory as an atheistic explanation of the earth’s rocks and biology, adding millions of years to earth history. The earlier biblical ideas of creation, catastrophism, and short ages were put aside in favor of slow and gradual processes and evolution over millions of years.
Looks like they really don’t know. They’re just guessing.
