Sixty-six million years ago, 70 percent of all species on land and in the seas, including the dinosaurs, suddenly went extinct, in the disastrous aftermath of the collision of a large asteroid or comet with the Earth. Subsequently, paleontologists discovered that such mass extinctions of marine life, in which up to 90 percent of species disappeared, were not random events, but seemed to come in a 26-million-year cycle.
In their Historical Biology study, Rampino and co-authors Ken Caldeira of the Carnegie Institution for Science and Yuhong Zhu of NYU’s Center for Data Science, examined the record of mass extinctions of land-dwelling animals and concluded that they coincided with the extinctions of ocean life. They also performed new statistical analyses of the extinctions of land species and demonstrated that those events followed a similar cycle of about 27.5 million years.
What could be causing the periodic mass extinctions on land and in the seas? Mass extinctions are not the only events occurring in cycles: the ages of impact craters — created by asteroids and comets crashing to the Earth’s surface — also follow a cycle aligning with the extinction cycle.
Astrophysicists hypothesize that periodic comet showers occur in the Solar System every 26 to 30 million years, producing cyclical impacts and resulting in periodic mass extinctions. The Sun and planets cycle through the crowded mid-plane of the Milky Way Galaxy about every 30 million years. During those times, comet showers are possible, leading to large impacts on the Earth.

Mayan calendar ping
BiXiden’s fault.
Steven Jay Gould already did this same analysis and came to the same conclusion 35 yeas ago.
And right now, 2020 is the 26,999,999th year
{sigh}
One can only hope.....
This has been known for awhile.

It can’t happen soon enough!
Yeah, God rebooting the planet would be preferable to what’s coming.
Based on their timeline it appears we have another 15 million years before this is a problem.
This is quite understandable.
It takes 26,999,999 years for a civilization to form, for it to have a 5000 year leap to create a Republic, for it to create a Supreme Court... and then in the last year, for it all to collapse, and start over again.
Nonsense. It’s a 12-year cycle!
Thanks. I was worried we only had 1.5 million years to go.
Yes, it's an old idea. They attempted to explain it with the "Nemesis Theory". That is, that the sun had a companion star, as most stars do. And, periodically, every 26 million years or so, that companion would stir up the comets in the distant Ort Cloud, sending some comets in toward the inner solar system and into a collision course with earth. They still haven't found compelling evidence that the sun in fact has a companion.
Another potential explanation was the Carousal Theory, or something similar to that, which theorizes that the galaxy, as it orbits around the galactic center, "bobs" up and down like a horse on a merry-go-round, and that that stirs up the comets in the Ort Cloud. I think they've since ruled that one out.
That’s cool.
Well that Settles it for me I’m not paying off my credit cards
Cool. I won’t stay up late for it then.
Once our cave-dwelling ancestors discovered “sushi”, it was all over for many species of edible animals. And then came the BBQ - Mastodon, Musk Ox, Giant Sloths. Nobody was spared (but they did become spareribs).
