Asteroid showers linked to mass extinctions, says study

quote:

Mass extinctions occurring over the past 260 million years were likely caused by comet and asteroid showers, scientists conclude in a new study published yesterday (October 20) in Monthly Notices of the Royal Astronomical Society.

For more than 30 years, scientists have argued about a controversial hypothesis relating to periodic mass extinctions and impact craters – caused by comet and asteroid showers – on Earth.

In their new paper, Michael Rampino, a New York University geologist, and Ken Caldeira, a scientist in the Carnegie Institution’s Department of Global Ecology, offer new support linking the age of these craters with recurring mass extinctions of life, including the demise of the dinosaurs. Specifically, they show a cyclical pattern over the studied period, with both impacts and extinction events taking place every 26 million years.

This cycle has been linked to periodic motion of the sun and planets through the dense mid-plane of our galaxy. Scientists have theorized that gravitational perturbations of the distant Oort comet cloud that surrounds the sun lead to periodic comet showers in the inner solar system, where some comets strike the Earth.

Specifically, he and Caldeira found that six mass extinctions of life during the studied period correlate with times of enhanced impact cratering on Earth. One of the craters considered in the study is the large (180 km diameter) Chicxulub impact structure in the Yucatan, which dates to about 65 million years ago – the time of a great mass extinction that included the dinosaurs.

Moreover, they add, five out of the six largest impact craters of the last 260 million years on Earth correlate with mass extinction events. Rampino said:

This cosmic cycle of death and destruction has without a doubt affected the history of life on our planet.

83% correlation with largest meteor craters? Pretty significant.

How did you want to approach this as a discussion topic?

maybe Creation/Evolution Miscellany

On the creationist side, the next "correction" is supposed to be by fire ... (the God's Wrath part)

On the evolutionist side the dating of the meteor craters and the correlation of them to extinction events that changed the course of life on earth, and that may even have bee critical for life forming on earth, forms an evidence based division into different chapters of the dialog of the natural history of the planet, one that is not over yet ... (the Comet Math part).

A problem for the YEC crowd is all those craters and their dates\sequences correlating with the fossil record of extinctions instead on one flood conflation: why do the craters mark different chapters in the story of life on earth?

Hi RAZD,

Well I don't have any such problem.

A couple of years back I was asking about how all the material that created the oil got into the earth at the depths and under the pressure it is under. That pressure is over 20,000 psi.

I suggested that the earth was much smaller in the past than it is today.

I then proposed that the earth was covered with vegetation/animal life and when it was very dense that there would be meteor showers that covered that vegetation/life forms.

After a period of accretion the earth would be covered with vegetation/life forms which would again be covered by meteor showers.

This continued until there was enough vegetation/life forms covered by miles of rocks and overburden to produce the trillions of barrels of oil, natural gas, and coal in the earth.

I can find no one who has expressed any idea how all the oil, gas, and coal reserves got to where it is today. Even YEC'S won't touch the discussion.

AIG states that there was only enough vegetation to produce the soft coal we have today, which they believe was produced during the flood.

I even gave the numbers for the amount of material needed. If my memory serves me correctly it take about 98,000 tons of material to make 1 gallon of oil. There is 42 gallons of oil in a barrel.

We have consumed about a trillion barrels of oil and there is still at least 1.64 trillion barrels left. But that number increases as better extraction methods are discovered. There is also 7.02 quadrillion cf of gas reserves.

Just to produce the oil would require 3,738,000 tons per barrel.
2.64 trillion barrels would require 9.86832e+20 trillion tons of material. That does not include anything for the natural gas, and coal.

Now when I first mentioned the earth was small and increased by accretion I got all kind of comments about my intelligence or lack thereof.

Anyway I would like to hear more about the earth being enlarged by accretion.

Added by edit:
You can find the discussion of accretion in Message 137 There are several messages in that thread this is just one. Sorry about my time memory it was in 2011.

God Bless,

Yes, you sure do. Most Gondwana coals are of Permian age. Indian, Australian, Southern African, South American...Unlike European, North American, Russian, Siberian, etc. coals. Those are Carboniferous in age.

Wait....

All this happened in the last 6,000 years?

How does this take into account the dectable differences in materials with a terrestrial origin and an extraterrestrial origin? That is, material that has it origins in outer space has a noticeably different composition than material that originates on earth.

Meteors and comets crashing into earth creates sedimentary rock?
--------------------------------------

This is just another example of YECs completely making stuff up with NO supporting evidence.

Note: It seems to me you may not be a youth earther in the strictest sense but may be an old earth, recent creation of life (gap theory) proponent. But if you accept an ancient earth, why bother making stuff up about how oil and coal came to be formed?

Why were you asking that question?

Did you pretend to be an oil geologist or any form or a petrophysicist or anything like that? How much time have you spent on an oil rig? How much time have you spent on oil exploration? Any?

Do you have any training in geology? In palaeontology?

I can find no one who has expressed any idea how all the oil, gas, and coal reserves got to where it is today. Even YEC'S won't touch the discussion.

What kind of argument is 'I could not find X'? Where did you look? If we want a YEC interpretation, what does Dr. Dino say about the origins of petroleum?

I did a search for oil reserves origins and found plenty of science based ideas about where the oil reserves came from and how they got where they were.

After a period of accretion the earth would be covered with vegetation/life forms which would again be covered by meteor showers.

Your proposal suggest that we should be able to find oil and gas just about anywhere. Does that conclusion reflect reality?

I think he is stuck with giving a young age for the plant life that became oil. According to the Bible, plant life and human life originated only a few of days apart.
