When our proto-star exploded, particles and solid pieces were hurled all over space. On the gravitational falling back some missed the Sun, which
moved position, and started to form orbits around it. Conditions were violent and collisions were the order of the day amongst objects as they start
settling into their orbits. ±4.5 billion years ago a possible planeloid, Theia collided with Earth to form the moon. The “late heavy
bombardment” happened around ± 3.9 billion years ago, the time when the Earth started forming solid areas.
Some Fun – There are no geologic records for the Hadean Eon.
Ok, let’s look at today where the Sun, Cosmic radiation, Volcanism and Impacts are the current most prominent contributors to Earth changes. The
climate is a secondary result of this and not part of this thread as atmospheric changes are common in our history and life is still around. Volcanism
intensity in turn is directly linked to the amount of cosmic radiations entering our Solar System affecting our planets. Ok, what does this mean?
Simply that when our Sun is in a minimum cycle or period it’s Solar forcing is less, which then allows the galactic cosmic rays to enter deeper into
our Solar System and/or when we move through changing outer-space particles and densities (clouds and their makeup). Currently our Solar System is
moving through “fluff” within our local bubble with a higher density, believed to create more friction and therefore the temperature changes
throughout our Solar System.
Local bubble drawing
This is our position in the remnants of a Supernova explosion within the Orion Spur. The most probable cause of this bubble is the Geminga Supernova
about 340,000 + years ago. According to my personal opinion this was the reason why Earth was so hot in the Triassic/Jurassic time period. And a hot
slippery Earthly mantle definitely helped triggering the eruptions of the Siberian traps that led to the most devastating known Mass Extinction ever
± 252 million years ago. But I think we leave this for the scientist to work on. However, I will put”snowball” Earth ± 600 million years ago on
the top of the list. Mass Extinctions happens repeatedly on Earth and are not limited to the big 5, we are in one now which are been highlighted due
to our shared knowledge. But I do not see scientist in 110,000+ years from now finding it to be an extraordinary event or us changing into a Venus
type planet yet. Extinction events are more prominent when the temperature changes, with the emphasis on cooling down stages. (Do not jump to
While statistical data sets give us a basic picture of the past, when going into the millions of years there are still many “thumb-sucks” with to
many blank spots in our Earths timeline as a result. Personally I would like to see more work done on our Solar Systems movement, which in turn will
do away with a lot of speculation. What’s up with our Solar Systems magnetic plane and its ± 90° tilt in relation to the galactic plane? Did we
really come from a merger of the Sagittarius Dwarf Galaxy? Why does Sirius seem to follow us in our precession cycle? It is time for it to become a
fact and do away with theories and hypothesis about bobbing like a sine wave and/or rotating around something else more local.
My thread has some personal opinions, feel free to differ.
Thanx, have a nice day and safe journey.
