The One Multi- Hypothesis: Domino Effect about Dinosaurs Extinction (DEDE)

The explanation of the Dinosaurs Extinction by a Variation of the Earth Gravity

« The HypothesiS »

 

...How and why the Earth gravity has necessary changed.

 

The first cause was the meteor collision.

This impact was always considered with a vertical direction.

But, there is less chance to have been like this than to have an angle. It’s logical, there are more angular values than the one 90 °!

An impact can be with a perfect perpendicular axle, of near, under two possibilities :

Its original way is like this, or its way has been changed before.

For the first possibility, the probability is low on a curve area ( 2 dimensions), and lower on a spherical area ( 3 dimensions), where there is only one place.

For the second one, the gravity changes the direction. But its influence is smaller that the object’s ratio speed/ weight is high.

To know the masterpiece of the theory, go to it.

I have come to the same conclusion as you have, through the following reasoning:

Any increase of the Earth's gravity implies an increase of the Earths mass. So I concur that it is plausible that a meteorite impact could add so much material to the Earth total mass as to increase the Earth's gravity.

.

Also, subsequent animal species that evolved after the dinosaurs never were able to develop nearly as much body mass as the great lizards, and that certainly implies that large animals, weighing more than 3 tons, could no longer be sustained by the Earth's environment,.

It has also been rather difficult for modern paleontology to make a credible model of dinosaur speed and motion, It was believed that dinosaurs were slow moving animals, judging from their bone-mass, but more recently the opposite view has been accepted, The debate whether dinosaurs where cold blooded like reptiles or warm blooded like birds further implies that much is still to be known about dinosaur metabolism.

It would be interesting to address these issues taking into account a lower Earth gravity. How would it affect the current models of dinosaur movement?
