What If (onTemp.extremes)

Something is missing for gas,and dust to create fusion. I think I have a
good idea that can solve the problem of a compressed gas expanding when
compressed. Expanding nebula's gas is moving its molecules in the wrong
direction for fusion. It takes millions of degrees F so we have to have
something to bring these gas molecules to together first so gravity can
do its compressing.and that something is great cold. lets go with 7 K.
At that point in spacetime its gravity that can't lose. Theory is it
takes the shock of sever cold to create extreme heat Beeert PS I
will add to this because I'm thinking good and my next thought that
keeps jumping in is these star creating clouds need a jolt
