Asteroid hit dino extinction theory strengthened by asteroid dust found in crater

Asteroid dust found in crater closes case of dinosaur extinction
The crater left by the asteroid that wiped out the dinosaurs is located in the Yucatán Peninsula and is called Chicxulub after a nearby town. Part of the crater is offshore and part of it is on land. The crater is buried beneath many layers of rock and sediment. A 2016 mission led by the International Ocean Discovery Program extracted rock cores from the offshore portion of the crater.

It’s been the leading hypothesis for decades but finding the dust is a bit like finding the murder weapon:

Researchers believe they have closed the case of what killed the dinosaurs, definitively linking their extinction with an asteroid that slammed into Earth 66 million years ago by finding a key piece of evidence: asteroid dust inside the impact crater.

Death by asteroid rather than by a series of volcanic eruptions or some other global calamity has been the leading hypothesis since the 1980s, when scientists found asteroid dust in the geologic layer that marks the extinction of the dinosaurs…

In the 1990s, the connection was strengthened with the discovery of a 125-mile-wide Chicxulub impact crater beneath the Gulf of Mexico that is the same age as the rock layer. The new study seals the deal, researchers said, by finding asteroid dust with a matching chemical fingerprint within that crater at the precise geological location that marks the time of the extinction.

The paper is open access.

The asteroid theory replaced any number of folk Darwinian theories about why the dinosaurs died out. You know the sort of thing: They were too big; they were too stupid to look after their eggs; mammals ate their eggs… Etc. Many non-dinos went extinct too. Small mammals may have found it easier to hide.

    There’s evidence of several of these planet-wide near-extinction events in Earth’s history. Does your Creator periodically get bored with His creations and decide to wipe the slate clean and start from scratch? Could that mean that we could go the way of the dinosaurs at some time in the future?

    Or is the takeaway lesson how resilient evolving life can be when it comes to repopulating the planet after such near-total catastrophes?

    The article accurately calls it an hypothesis due to not having witnessed the event in question. Without witnessing something, it cannot be a theory. Evolution has never been witnessed by anyone, unlike adaptation, yet Darwinists will continue to call it a theory without the belief matching the requirement.

    Darwin’s first two books directly led to competing socialist views during the last century. Socialism/communism and eugenics. Both ended up costing a great deal of human lives while spreading a great deal of misery. Eugenics is beginning to rear its ugly head again, but socialism never stopped being out of fashion,

    Lenin was a greater Russian socialist who believed all the nationalities had to fall under Russian rule, which included Georgia. He payed lip service to the idea of nations existing under Soviet Rule as independent to get the support he needed to take power, which is why he had Stalin write an essay about nationalism.

    Trotsky had fallen out of favor when Georgia took Lenin up on what had been promised and became an independent socialist nation, which existed for three years. Stalin was given what had been Trotsky’s Red Army to crush the independent nation through a great deal of blood. Trotsky did not believe in nationalism of any kind, which was the only point of disagreement between him and Lenin, which was enough to cost him everything, since Lenin was a Russian national socialist.

    Being free to pursuit passions is when the technological advancements have occurred. As long as we don’t lose focus on space, the next extinction event can be avoided by being off planet. Focusing on the wrong things, such as man-made climate change (the last Great Ice Age ended 10,000 years ago with no help from man to start anything), we can be prepared for whatever nature throws our way.

    Paleontologists should have learned to avoid “definitively linking” and “sealing the deal”.

    More broadly, we tend to think of every big change as an extinction. In commerce and technology we talk about Creative Destruction, the buggy whip replaced by the automobile. It didn’t happen that way. Buggy makers SLOWLY morphed into motorcar makers, just as dinosaurs SLOWLY morphed into birds. Creative Destruction is used as a cover story for REAL destruction when entire industries are MURDERED by bankers and LBOs, letting China have the entire industry. Destruction is destruction, mass murder is mass murder. Nothing creative about it.

    If the dinosaurs slowly morphed into birds, where are the mutations in the fossil records. It is not just the lack of missing pieces over the course of millions of years, but a complete lack of positive mutations of even a single line for any given species. Speciation, unlike adaptation, has never been witnessed by anyone. If something is not witnessed, it is no more theory than the multiverse, which remains purely hypothetical.

    The problem that comes from guessing the age of any fossil is people tend to not pay attention to just how much earth was moved by the various Ice Ages that have come and gone over the course of billions of years. Earth movement by ice skews the results of anything found in the ground.

    Where is the evidence of speciation? A 30-year study of E. coli, the equivalent of 1,000,000 years to humans, found what was already known. E. coli adapts, but never showed a single positive mutation that would have led those involved in the study to believe they had the evidence. If they had a breakthrough to prove speciation exists in nature, the study would still be happening today.

    I think Polistra was being sarcastic about Darwinism.
    I hope so, anyway.

    Regardless of sarcastic intent, I believe my answer should get some people thinking. Not that the thoughts will lead to anything, since Darwinists have an amazing ability to ignore everything.
