Known as the Chicxulub impactor, this large object has an estimated width of 6 miles (9.6 kilometers) and produced a crater in Mexico’s Yucatan peninsula that spans 90 miles (145 kilometers). After its sudden contact with Earth, the asteroid wiped out not only the dinosaurs, but around 75 percent of the planet’s animal species. It is widely accepted that this explosive force created was responsible for the mass extinction that ended the Mesozoic era.
The impactor in the article brings up an interesting discussion. Since the impactor killed off 75% of life on the Earth when it collided with Earth we can paint an image of the Earth and determine a more precise, but not direct impact on when life started on Earth.
When the impactor collided with Earth, not only did the collision throw millions of tons of dirt and dust into the atmosphere that blocked out the Sun, the impact also caused widespread amounts of carbon dioxide to blanket the Earth, resulting in a suffocating veil that the Sun was unable to penetrate for many years.
Now, if we rewind the events of the Earth, to a point when the Earth was constantly being bombarded by small impactors on a daily basis that had been orbiting the Sun and resulted in a 25% increase in mass of the six mile wide dino killer, we can see that total destruction of Earth’s surface would have taken place at 100%, every day until the collisions stopped.
The Earth could have been solid at this point, much like the planets of Alpha Centauri are thought to be rocky precipice of life. Water might not have been present yet on Earth, as any water source would have quickly evaporated due to trees and plants not being present to consume the water and create air by consuming carbon dioxide as well.
Imagine a large rocky plain with carbon dioxide clouds as thick as soup. Any water on the Earths surface would quickly evaporate and then bond with the carbon. Not until the Earth cooled to point of 68 degrees would the first lakes of water begin to take form. Prior to water forming as liquid on Earth, life would not have existed, not even in stasis as DNA and RNA requires liquid water to exist.
Since water is lighter than carbon dioxide at the molecular level. the warm, evaporating water would have risen above the carbon dioxide clouds and cooled into rain. Rain that could have helped the dust settle, like you would see a roller on paving crew using to keep the dust down, help cool the pavement as well as not sticking to the pavement, which in this case would be the soil. As the carbon dioxide was beat into the ground by the rain as well as rising into the atmosphere, like a dwarven warrior with a large hammer type of beating, the Sun was finally able to regulate the temperature of the Earth that allowed for liquid water to be constant. So at whatever point the Earth’s troposphere cooled to 68 degrees is when water begin to form on Earth.
At about 140 million years old, fossils from a huge dinosaur dug up in Argentina might be the oldest titanosaur yet discovered, scientists announced this week in a new study.
Titanosaurs are a group of long-necked, plant-eating dinosaurs that may have been the largest animals ever to walk the Earth, according to Reuters.
The dino killing roid struck 65 million years ago and either orbited the Sun for 75 million years or traveled from another location in the galaxy for 75 million years before colliding with the Earth.
Monkey’s commonly thought of as the closest relatives to humans come into existence roughly 30 million years ago with humanity having a recorded history of coming into existence around 300,000 years ago.
So why didn’t humans develop around the same time that dino’s developed 140 million years ago? The environment would have been good enough for humans to thrive in, but we don’t see humanity coming into the history of the Earth until 300,000 years ago or 27 million years after monkeys.
Therefore the asteroid that struck 65 million years ago and killed off the dinosaurs was the asteroid that carried the necessary components for monkeys to come into being and then later on, humans.
But did the dino roid come from inside the Sol System from a 75 million year orbit around the Sun, or did the Dino Roid come from deep space where other similar roids, encountered planets like Earth, filled with carbon and slowly developing water that orbited a yellow dwarf star just like our own?
I would have to say the later.
There is life in the Universe other than on Earth.
