○Stars are born when pockets of gas and dust within interstellar molecular clouds exceed critical density
and collapse under their own gravity. Once the pressure and the temperature inside get high enough for
nuclear fusion to ignite, it creates a star.
○star is born when atoms of light elements are squeezed under enough pressure for their nuclei to
undergo fusion. All stars are the result of a balance of forces: the force of gravity compresses atoms in
interstellar gas until the fusion reactions begin.
○star requires hydrogen gravity and Time
○gravity pull the dust and gas into a giant squerlling fortix gravity brings the matter together that when
you bring the matter together then you sequeez things in a smaller places they necessarlly heat up.
○100000 and 10 million years
A protostar is formed as gravity begins to pull the gases together into a ball. This process is known as
accretion. As gravity pulls the gasses closer to the center of the ball, gravitational energy begins to heat
them, causing the gasses to emit radiation. At first, the radiation simply escapes into space.
