Earth, Star Child?, Are we leftovers from a supernova?

[roam]

Hello everyone,
I have heard a theory that earth and earth's solar system are all leftover from a giant supernopva.
I generally agree, but I don't know. Was their just Hydrogen in the begining? Did the big bang make some denser elements as well? Will the Universe die in fire (Big Crunch [Dark energy goes backward]) or ice (Big Rip [dark energy rips the universe apart])

there, i just saved 3 gigs of space on the forum server.

Roan.

If I remember correctly, it starts with the Big Bang. The galaxies are then created. The super hot hydrogen creates the biggest stars which are sFper hot but have short life spans ( of course this is relative) Millions of years. These stars die having never left the stellar nursery. These stars created the heaviest elements like uranium and the other rarer stuff. from these stars other stars formed from their deaths. These stars were smaller yellow stars like our sun. As things cooled, planets and solar systems formed such as ours. In essence we are all made of star stuff. If you are brand new to the study of physics, Carl Sagan's Cosmos is the best place to start. Second, I recommend Walter Isaacson "Einstein", also "Evolution of Physics" by Einstein. After these you are then ready to understand Hawking's Universe. I am new and I found this route good for me. As to understanding all the math I have no idea where to begin. If you are an old hand do not feel insulted I answered if you were new like me.

I would vote that we will go by way of the big crunch. At least according to the books I read on the subject and the documentaries like "Cosmos" and "Hawkings Universe" it seems that there is enough hidden matter to wrap the universe around it self locking us in forever. Every time we use a different form of light to view the universe we fond more matter out there giving us the necessary gravity needed for the big crunch. I also liked the way Hawkings said it "I will place my money on the Big Crunch but I will not be around to collect." I thought this statement funny but still informative because coming from the mind of Einstein's successor means alot, in my opinion.

The creation of the universe also created the 4 dimensional grid. Does anyone here know the math that describes the grid? Has any physicist tried to "hack" their way into the grid to see what would happen? Like the invention of the air plane to overcome gravity has anyone tried to overcome the grid? If so what was the result in the lab?

Yes, there are some people here that do know that sort of math. I'd be curious about that one too...hacking one's way (never quite heard it put that way before.)

In order to get the elements we see here on earth there must have been some supernova remnant in the cloud of gas that made the sun. Quite literally in the words of Joni Mitchell "You are Stardust."

What Horta says about the big bang model is pretty good. The only thing I'd like to add is that we can calculate the quantities of various elements formed before stars had a chance to form. It comes out as 75% Hydrogen 25% Helium and a tiny smattering of lithium. All the rest was made by stars.

As for the question of where the universe is going, theres not one single view that's gained acceptance like the big bang has. It seems that the expansion of the universe is accelerating, which is a bit of a puzzle, as gravity should be causing the expansion to slow. IMO this is an open question in cosmology.
