There was a special done on the discovery channel that compiled enormous amounts of data gathered from the Hubble telescope that summariZed the observations of many scientists as to the framework of our universe. It outlined key points such as how stars are formed and their behavior throughout their lifetimes. Google the pillars of creation which are five Light year long pillar clouds of hydrogen dust and other elements that supercondense and eventually ignite into stars.
It also observed the map and layout of all the stars and galaxies that are visible to us. Apparently there are gaps and spaces throughout space where dark matter exists, it is a force that we cannot perceive with our eyes and the only reason we know it exists is because nothing else is there. It appears dark matter actually provides the framework that maps the formations of where galaxies exist.
Also contrary to the theory that everything will collapse back to the point of the big bang Hubble has actually observed that the rate at which we are moving apart and outward is actually accelerating. What scientists believe is that we will now continue to accelerate at increasing speeds until we eventually hit a velocity where gravity is no longer enough to hold matter together. The entire universe will essentially deconstruct at a molecular level and be ripped into strings of atoms that stretch across the cosmos.
Your right about a lot but I`ll fill in a few bits.
We know dark matter is there because of the gravitational effect it has on nearby space objects made of "normal matter". Matter has a gravitational pull proportional to its mass as you know so dark matter does too. Sorry if you ment that.
So now that dark matter will have a gravitational effect too, its going to have a major influence on the expansion of the universe. Your talking about the great expansion theory. There are 2 outlooks.
1) (Pesimistic) We keep expanding until the distance is so big it doesn`t make sense to measure it (cold huge place)
2) (Optimistic) Dark matter plays its role as we don`t know what its capable of and counteracts this expansion.
But the truth is the thinking the universe is going to balance doesn`t make sense. Its either going to expand infinately or contract and keep blowing up many times and forming a fresh universe each time.
These are all opinions and theories though.
I mean who knows for sure??
Your theory is not illogical I just don't think it's likely, if our planet was a star at one point it would have to be of equal size to our sun to maintain even gravity and even then they would spin off each other. If they were smaller than each other the larger star would merge with the smaller.
We aren`t talking about 2 stars. 1 star which blows up and throws its matter into space, earth begin a piece of a star flung around space and eventually ends up orbitting another star as a piece of rock. At the right distance with the right constituents and presto, we have planet earth!! And the RIU community!! lol
(I`m not a physicist the source for this is Stephen Hawking - Journey to the Center of the Universe" everybody bearing interest its seriously great graphics and information!!)
