Just as the Earth and other planets rotate around our Sun, our solar system has a rotating trajectory around our galaxy Milky Way. And I must say…before I leave this plane of existence, I feel confident future research will reveal new evidence announcing that our galaxy (along with neighboring galaxies), will have a periodicity rotation with cyclical parameters rotating around…what is yet to be discovered.
The Earth is regularly exposed to cosmic rays as it oscillates upward through the galactic disc. Every 60 million years or so, astronomers believe that our Sun and planets cycle northward in the galactic plane. Just as the Earth has her magnetic field, Milky Way has its own. Without the galactic plane’s magnetic field shielding our solar system, we would be at even higher risk of radiation exposure.
The idea the evolution of life is punctuated by major extinction events with intervals of many millions of years is well established. Familiar episodes include the Cretaceous – Paleogene transition (65.5 mya), which saw the final demise of the non avian dinosaurs and many shallow sea life-forms, and the end-Permian (251 mya) when an estimated 56% of marine genera became extinct.
It is hypnotized the closer our solar system travels to the galactic center, we researchers observed a correlation between these cyclical events and its concordance with partial and mass extinctions transpiring with measurable regularity on Earth over the past 500 million years.
Identifying mass extinction signals is part of a wider search of periodicity to causal processes associated with geological events. Previous studies have identified a variety of periods including:
1) 26-35 Myr. (million year) geo-period evidenced by mantle plumes, flood basalt, and large igneous provinces (LIPs): 2) A 60-62 Myr cycle identified by marine genera, sea level and LIPs: 3) A 135 -145 Myr. cycle established by marine genera, and oxygen isotope records and also identified a ice age epoch.
I’m guessing some of you know where I’m going with this new series of research articles. However, I believe most of you are still not quite sure. I must say, it has been a long-long time since I had to re-written 2 or 3 times on this article and the previous ones. I feel confident this series of articles are very important and perhaps it may be difficult for one to wrap their mind around this information realizing how closely connected our little planet is to our solar system and galaxy.

At this moment I truly can’t say how many parts to this series there will be. I am certain of at least two more after this one, but 3 to 5 additional is not out of the question. I wish to thank you the two or three of you for your contribution. It comes at a good time. I have made a choice to dedicate a significant amount of time to these new understandings, and it is very important for me to present them to you in a method and style which most people will understand; and eventually all of you.
Coming Next: Part VI – Coming Friday but not sure of title as of know
