Ask Ethan: Are We Due For An Extinction Event On Earth?
Forbes/Science ^ | 6 Feb, 2016 | Ethan Siegel

Posted on 02/08/2016 2:49:40 PM PST by MtnClimber

While a great many people argue about how and whether the human race will end, there's no doubt as to the primary cause and catalyst of the last major extinction here on Earth: a massive, large body from outer space colliding with Earth. Some 65 million years ago, an asteroid about 5-10 kilometers in diameter struck what is now the Gulf of Mexico, wiping out roughly 30-50% of the species on our world and ending the age of the dinosaurs. Are we headed for another such event in the near future? Reader David Bertone wants to know:

I have a question for you regarding [this article I read on] how our galaxy's disc displaces comets in the Oort cloud every 26-30 million years, causing periodic extinctions and bombardment of comets on Earth… I was wondering if we are in any danger of this happening in our lifetimes, and if the theory itself is credible?

To be honest, there's always a danger of a mass extinction, but the key is quantifying that danger accurately.

I am less worried about an asteroid than the N Koreans and Mullahs having nukes. Still an interesting article and something other than politics!

Yup - it’s coming. However God is going to keep a small remnant of Jews hidden in Petra while the rest of the earth is completely destroyed. Soon, but IMO not for a few decades. However, I would be surprised if we get out of this century before it all comes down.

If you’re a believer, not to worry - Jesus will take us before it all comes down. We’ll be watching on the Big Screen in Heaven’s mezzanine.

I would be more concerned about the Sun’s continued declining magnetic field...when no sunspots are formed expect another ice age.

It’s not like we’ve kicked God out of the schools and public arena. Or made gay marriage a fundamental right. Or abort a million kids a year. Or allow Satanic prayers in public places.

There is a theory that a virus took out the large dinosaurs. The layer of earth generally associated with the meteor is located above most Dino’s. Most of the large species had been dead for quite a while when the comet/asteroid hit.

Yes, we are nearing the average end for years of interglacial warming periods. Average is 20,000 years or so and we are at around 16,000 years. When the sun spots go away we are in for some big “climate change”.

Yes.

2nd Peter 3:10 “But the day of the Lord will come as a thief in the night; in the which the heavens shall pass away with a great noise, and the elements shall melt with fervent heat, the earth also and the works that are therein shall be burned up.”

Any questions?
