To planetary formation
.......................................................................................................................................................
The most widely accepted theory of planetary formation, known as the nebular hypothesis, maintains that 4.6 billion years ago, the Solar System formed from the gravitational collapse of a giant molecular cloud which was light years across. Several stars, including the Sun, formed within the collapsing cloud.
The of 'Acretion'. hypothesis assumes that objects with a differential speed of thousands of miles per hour collided with each other and stick.
At the same time they assume that OTHER objects with a differential speed of thousands of miles per hour collided with each other and exploded.
Or...as demonstrated on earth.
Umm...yeah.
The Ganymede Hypothesis has an alternative explanation. I found it to be fascinating. Awesome CGI too.
Hard to say what really happened 4 billion years ago!
that would be true.
why do we assume it happened that long ago?
With my vast knowledge of all this stuff, and looking at the 'electric universe for dummies' - it seems to me things are more logical with this hypothesis, and everything 'fit's' ... with fewer anomalies (like dark matter and black holes for example...)
There's a lot more about it now than there once was.
I'll be posting more.
Oh wait! I just did.
