Title: Is This Information About the Formation About Our Sun Moderately Accurate?
Post by: Gordian Knot on 29/03/2013 14:17:49

I was reading an article on a website which suggested that the sun and solar system were born with the Big Bang!!!!!! Now I know I am an amateur, but even I know that is totally bogus.

So I wrote a simplified, abbreviated correction to the site. I'd be grateful for some feedback if what I wrote is mostly accurate as, again, I am no expert.

This is what I sent them:

The information about the formation of our sun is incorrect, and it leaves out a huge portion of the story.

The gas and dust that eventually formed our sun and solar system was not created from the Big Bang. The Big Bang is currently believed to be roughly 14 billion years ago. Our sun is believed to be 4 1/2 billion years old.

A lot happened between the Big Bang and when our sun finally formed. After the Big Bang and expansion of the universe, the first stars to be formed where massive super stars, monstrously larger than anything but perhaps the largest stars currently in existence.

The early universe was filled with these star giants. It was their deaths, as supernovas, that created and released many new, heavier elements that would someday become stars like our own, and also the planets.

Hope this is of some help.

You missed out Galaxies. They are surely of major importance.
