Nebular then and Now

Has to be a good theory that 13 billion years ago the first stars were
just about supernova. The greater density of the nebular would account
for that. These clouds had great hydrogen density,but no dust. Next
phase came stars from a less dense nebular but still with as mass of
about 3 suns,and their fusion was triggered faster because of the shock
waves created by supernovas. Now supernovas leave a blackhole,and these
blackholes would create lumpy space where stars would form around them.
These exploding supernova would create the building blocks for
planets,and life. Phase 4 is the time of medium size
stars(suns) They came to be 5 billion years ago.They came from thinned
out hydrogen,and dust clouds . These are the stars that are just right
for life because they can last 10 billion years(average) Phase 6 time
is "now" it is the time of low mass stars we call "red dwarfs" they are
very dim,but last a very long time. In the
universe there are billions,and billions more gas planets than stars.
Phase 7 that is just about ready to arrive will be a time of gas
planets,and the building blocks of rock planets was just about over in
phase 5 It all came out of times of mass density
created by gravity,and the number and type of atoms gravity had to work
with. Bert PS Left out a lot,but for me this is a lot of typing
