Twenty million years?! With all these volcanos popping off right now I thought they were going to say we were in the middle of one of these pulses right now, lol. Oh, ye little men of little minds, ye know not of what I can do. (Don't know who said it, but he should have!:-))
Of course, the mayhem that will take place in 20m years will have been caused by global warming. We know this for a fact. The science is settled.
Those major extinction events were probably because of a giant field of giant space rocks. The Earth is moving along with the Milky Way Galaxy in a circular pattern. Part of that pattern involves traveling through an ORT Cloud. The ORT Cloud is the giant field of giant boulders. A space rock say 5 miles wide smashes into the Earth and there could be lots of damage. Maybe next time there will be rockets to blast the space rocks into dust so the Earth will be saved.
That is about the same as the time for the solar system for each pass through the galactic plane. The time for a complete oscillation from one side of the galactic plane to the other side and back is about 60 million years which makes about 30 million years for each pass through the denser galactic plane.
Interesting reading, thanks for posting.
If they had only stopped using fossil fuels 27.5 million years ago it would not be hot in June!
Damn you Fred Flinstone!
Looks more like it correlates to the Precession of the planet.
There have been a couple of attempts to explain this:
*The Nemesis Hypothesis - that there is a small star or large planet that orbits the sun and once every 27 million years comes close enough to our neighborhood to toss large rocks at us
*The Shiva Hypothesis - Every 27 million years the solar system passes through the plane of the galaxy. This causes gravitational disruptions that send asteroids our way.
Yeah, I can see that right on the mark at 27.5 million years give or take a day.
What bull this is.

226 million years for one turn around the galaxy so about 8.2 events per tour. IF the pulse is a known, and our speed is also given as a known, then calculate the star charts forward to discover what quadrant of our galactic tour the event will occur in, down to the season and month. Not that there’s any guarantee our galactic speed or the speed of our sun, is a constant.
