what an alignment!
maybe Sol is helping Gaea shake off malevolent species before its too late?
Sep 10, 2019 · Scientists believe that the Earth is currently going through its sixth mass extinction event.
What interests me is the time period alignment of the astronomical events with the Permian-Triassic mass extinction.
Denovian extinction was 440 mya as well.
A major extinction, the Kellwasser event, occurred at the boundary that marks the beginning of the last phase of the Devonian period, the Famennian faunal stage, about 376–360 million years ago.
So what ever caused it, it took a very long time.
Although it is clear that there was a massive loss of biodiversity in the Late Devonian, the timespan of this event is uncertain, with estimates ranging from 500,000 to 25 million years, extending from the mid-Givetian to the end-Famennian.
cryogenian period ended 660 mya,
The Cryogenian is generally considered to be divisible into at least two major worldwide glaciations. The Sturtian glaciation persisted from 720 to 660 million years ago, and the Marinoan glaciation which ended approximately 635 Ma, at the end of the Cryogenian.
The idea that mass extinctions are periodic is an interesting and compelling one, but the evidence simply isn’t there for it. The idea that the Sun’s passage through the galactic plane causes periodic impacts tells a great story, too, but again, there’s no evidence. In fact, we know that stars come within reach of the Oort cloud every half-million years or so, but we’re certainly well-spaced between those events at present. For the foreseeable future, the Earth isn’t at increased risk of a natural disaster coming from the Universe.
