A 4-Billion-Year-Old Piece of Earth's Crust Has Been Identified Beneath Australia
ScienceAlert (via MSN.com) ^ | 09 July 2022 | David Nield

Scientists can use various clues to figure out what's under Earth's surface without actually having to do any digging – including firing super-fine lasers thinner than a human hair at minerals found in beach sand...The edge of the ancient piece of crust appears to define an important crustal boundary controlling where economically important minerals are found...

With all that jumping, stumpin and bumpin around, Chris has inadvertantly loosened a small portion of the Earth’s Crust!
The effect is seen 180* latitude from where Chris Christie now lives in the USA.....//

LOL! Earth’s crust. Fault lines. You’re right. It does work!

Bingo! 13 billion , six billion, 24 billion, who the hell knows. Now we are told that a part of the Earth’s crust, mantle, is younger than the rest? So suddenly it was formed in piece meal fashion? What nonsense. Keep throwing the crap against the wall, see what sticks, and see what the useful idiots believe.
These clowns have no shame, and no integrity, a shame no one ever calls them on, only because they are in the same camp as the godless left, knowing nothing but godless propaganda, devoid of truth.

No, the Earth is about 4.5 billion years old. That makes 4 billion year old Earth crust a big deal.

Are you sure, and how do you know?

When I was little I read that the earth was massed at 6.6 sextillion tonnes

even as a young child I considered this strangely coincidental

It’s the generally accepted age for the Earth based on radiometric dating. It’s pretty straightforward to calculate the age of rocks based on the ratio of source isotopes to decay products and half-lives of specific isotopes in minerals in rocks. The method has been around for over 100 years. The half-lives of radioisotopes is well known.

No. The Earth is really that old? Why? All those metrics are not verifiable. The same with humans. One million years? Do the math on population and get back to me. So all the stars have an infinite life? Wikipedia? HaHa.

There are lots of duplications in one’s family tree. Assuming 25 year generations, in 250 years one has 10 generations and 1048 (2^10) ancestors in the 10th generations back. In 500 years there are 1,098,304 (2^20) ancestors in the 20th generation back. Thirty generations back there are over a billion ancestors.

No, stars don’t have infinite lives. In the 15 or so billion years since the Big Bang, there are several generations of stars. Really large stars burn through their fuel more quickly than medium sized stars like the Sun. The fact that there are elements with atomic numbers greater than 26 (iron) in the Earth means that a fraction of the Earth is made up of previous generations of stars that went super nova. Elements 26 and above require more energy to make than is released by fusion to create them. A star will go super nova within seconds of synthesizing iron.
