Order from Chaos: The Birth of the Solar System

The solar system formed from a cloud of interstellar gas and dust cloud about 4.6 billion years ago. Life began on earth about 3.5 billion years ago following a period of intense bombardment by asteroid fragments and comets, intense volcanism and finally development of a stable crust and a hospitable atmosphere. Thanks to more powerful telescopes and other state-of-the-art observational methods, we can now see "stellar nurseries" and young stars at various stages of formation. In this talk well learn what triggers star formation in clouds, circumstellar disks and planet formation within the disks, and well discuss early life on earth.

@Chuichupachichi exactly

This exceptional caliber of credibility clout within academia, is first made possible, then preserved, by the intellectual tariffs that were imperatively imposed upon the Calvary Chapel education system. The secular sentience was secured by disadvantaging the perfunctory private pupils & their mentoring Creatards & Religotard proponents that threaten to infect with illiteracy infestations. Thereby, devastating the pensively primatological, cavernously configured, cretinous cranial cavities

"Our solar system was triggered by an explosion from a very close Supernova"

An explosion would involve energy being transferred from a system & radiating towards an equilibrium state, as it progressively dissipates & becomes unavailable for work during the span of time in which the explosion occurs

Our solar system has been known to exhibit spheres, which happen to be the geometric figures with the greatest degree of order

Final analysis -> Explosions are causative of great degrees of order

[Chuichupachichi]

Its no wonder that the intellectual class never ceases to be amazingly systematically ordered in their executed processes. Especially ever since particularly constructive Professorships exploded onto the academic scene, after advancing their illustrious careers from the ranks of the Weather Underground

@romillyh The Universe is indeed about 14 billion years old, but it's expanding. So light from 14 billion light years away is the farthest light we can see. However, the expansion of the universe has carried the galaxies that emitted that light much farther away from us in the intervening time, so the observable universe is about 78 billion light years across.

@romillyh actually the 78 billion light years number is considered accurate for very easy to understand reasons. in fact it may be quite a bit larger

[romillyh]

"This is a picture of 78 billion light years."

Go figure. As I tried to do throughout this presentation. And I'm a scientist. A jumble of interesting facts, but so little explanation or discussion. Stars made from clouds of carbon and silica? Earth with a molten surface at 4 billion years? And then this remarkable statement (in the ESA clip) about a "picture of 78 billion light years." Pictures stop at 15 billion years, surely?

How does this kind of presentation of science enllghten anyone?

The theme music is dreadful!
