Better late than never ping.

[ml/nj]

Does this mean all the fairy tales I learned in college were wrong?

“The Earth and moon formed later than previously thought”

Oh nooez! That completely discounts all of TToE, since the Earth is only 6,000 years old and this proves so-called “science” is just guesswork!

The Earth and Moon were created as the result of a giant collision between two planets the size of Mars and Venus.

I mourn their loss.

(sniffle...)

[Chaguito]

Computer models of extremely complex processes. I shudder.

The Earth and Moon were created as the result of a giant collision between two planets the size of Mars and Venus. Until now it was thought to have happened when the solar system was 30 million years old or approx. 4,537 million years ago.

The Earth and moon formed later than previously thought

Stop with the lead in via a history lesson, just take my G-d d@mn wallet now and leave me in my peaceful destitution.

[The Cajun]

Soooooooo, the earth is 3% younger than previously thought, well that certainly changes everything.

[MadMax, the Grinning Reaper]

Happy Birthday to us.

What if it took longer than 100 million years between the supernova(e) that created the radio-hafnium and the formation of the solar cloud proto-planets? hummmm?

[KarlInOhio]

It takes 50-60 million years for all hafnium to decay and be converted into tungsten,

The half life of Hafnium-182 decaying into Tantalum-182 is 9 million years (Tantalum-182 to Tungsten-182 is only 114 days). In 54 million years there would be 6 half lives, leaving 1.56% of the original hafnium atoms. That's not a lot, but no one would say that "all" had decayed into tungsten.

[grey_whiskers]

I'd love to see a sensitivity analysis on both the turbulent mixing model, and on the measurements of tungsten.

Incidentally, is there a date ad terminus on the collision?

Cheers!

The Universe is very old; experts agree.

[mowowie]

Will this affect my Vegas plans next month?

;)

[Riptides]

Gee, I must be a moron.
I always thought God created the Earth and the Moon.

[LiteKeeper]

How about 6000 years ago? That is the biblical position.
