Earth Journeys

Last Updated: 10th Feb 2019

By Dave Crosby

We live in an increasingly dangerous universe.

The number 1 Geologic process in the universe is IMPACT.

Our rotation speed at the equator is about 1,037 mph (1,670 km/h).

Our orbital speed around the sun is about 67,000 mph (107,000 km/h).

The Solar System orbits the Milky Way at 200 kilometers per second, or at an average speed of 448,000 mph (720,000 km/h). Each trip takes about 230 million years to travel all the way around the debris filled Milky Way.

Andromeda, some 2.5 million light years away, is moving towards our galaxy at around 300 km/s.

The Milky Way is headed towards Andromeda, and the local group is being attracted to the over-dense regions and repulsed by the under-dense ones of the Virgo Super Cluster, giving a number for how fast we're actually moving through the Universe at 368 km/s

If we ignore the Earth's motion, we find that the Sun moves relative to the CMB (Cosmic Microwave Background) at 368 ± 2 km/s, and that when you throw in the motion of the local group, you get that all of it — the Milky Way, Andromeda, the Triangulum galaxy and all the others — are moving at 627 ± 22 km/s relative to the CMB.

Will our universe (which began in a BIG BANG) dissipate into nothingness or end up in a BIG CRUNCH?

I believe our big bang was the opening of a black hole in a previous universe. With all the stuff around us it looks to me that the previous universe ended with a big crunch, and we will end the same way.

“Meanwhile, back at the ranch . . .”

At present Earth’s continents make up ~ 30% of the surface, the oceans the other 70%.

As continents collide they either subduct or accrete the islands, ocean floors - mantle material that has cooled into basalt, and sediment that was between the masses before collision.

4.5 Billion years ago, what crust remained after the collision that formed the moon?
0% ? 25% ? All we have is guesses, BUT we have found rocks that are 4.4 Billion years old, so my guess is at least 20%.

Jack Hills, Australia, where rocks were found to contain the oldest known minerals on Earth, a 4.4 billion-year-old zircon. Just three of the very oldest zircons have been found, ones that date back to almost 4.4 billion years ago.
. . .

Confirmation of the zircon age holds enormous implications for models of early Earth. Trace elements in the oldest zircons from Australia's Jack Hills range suggest they came from water-rich, granite-like rocks such as granodiorite or tonalite, other studies have reported. That means Earth cooled quickly enough for surface water and continental-type rocks just 100 million years after the moon impact, the massive collision that formed the Earth-moon system.

SO - The New Continent accretion since then is probably less than 10% of the present total earth surface.
The earth has been in the temperature range of water freezing and melting far longer than previously guessed.

Right off the bat earth became a differentiated planet. The collision that formed the moon must have helped settle the last of the heaviest elements to the center of the planet (where the radioactive elements are still keeping us warm), . . .
So what elements are left in the crust?

Earths outer layers

And what elements are left in the mantle? See above.

For centuries people have been discovering valuable mineral deposits. Most of those minerals are not normally in the crust or mantle, so there is something wrong with the standard explanation that they are brought up by volcanic action. "You can't get blood out of a turnip," and you can't get silver or gold out of a magma if it isn't there in the first place.


NOW, ABOUT THE IMPACTS: (There is so much more than the "Oort Cloud Hypothesis" going on!)

The Milky Way Galaxy is about 13.2 Billion years old. Scientists have discovered galaxies average one supernova about every hundred years, so we are surrounded by around 132 million supernova remnants zipping around.

Milky Way

Our Location in the Milky Way

We return to the supernova of our birthplace every 226 million years (one Galactic Year), but supernova material travels out at about 1/10th the speed of light, so every ten years it has scattered one light year further from it's original center, so each time we return to that supernova location, the material has scattered ~ 22.6 light years further out.

What elements are in those supernova remnants? We have learned that the stars are element factories. The larger the star the heavier elements it produces. Silver primarily comes from stars about 8 times larger than our Sol.

Oh yes, I should mention that in those cometary knots are chunks of the planets that once revolved around the star.


Cometary knots condensing

Each full trip allows the Supernova Material to expand its radius by (226m/10 =) 22 million light years, but all is still part of the Milky Way dust and larger particles we travel through.

NOTE: Scientists have recently speculated that there are more "rogue planets" that have lost their stars in the Milky Way than there are stars.

Divide 4.54 Billion years the earth has existed by 226 Million years per trip = about 20 full trips we have made around the galaxy so far. How many other Supernova debris fields have we passed through?

Earth Travels

So multiple encounters with asteroids and comets from many supernovas is what accounts for the unusual deposits in ancient earth layers containing lead, strontium, silver and gold.

Think about it.

Thanks for the interesting article!
We are living indeet in a dangerous universe, so we should use the time to collect minerals before an impact destroy our mineral displays.

Sorry, I got interrupted - had to go to a funeral 300 miles away - and just got back to finish this.

Thanks for the comment Martin.

"BUT we have found rocks that are 4.4 Billion years old"

Please, do tell me where we find rocks on Earth that are 4.4 billion years ago?

I don’t recall ever hearing of asteroids or comets rich in those elements? It would be good to list references for such statements.
