What evidence is there for the Big Bang?
Left over radiation should still be where it blew up
left over radiation from the big bang covers the galaxy with radiation.
the cosmic microwave background radiation was discovered
redshift
the displacement of spectral lines toward longer wavelengths
star composition
When stars form in the present Milky Way galaxy they are composed of about 71% hydrogen and 27% helium, as measured by mass, with a small fraction of heavier elements.
keplers first law
All planets move about the Sun in elliptical orbits, having the Sun as one of the foci.

How do stars produce elements?
When pushing other elements together creates a reaction causing the star to make more elements.
nuclear fusion
Why does an object go faster as it gets closer to its star?
The closer it gets the stronger the gravity pull
Its like flinging a ball around a pole that has a rope taped to it the ball will get closer to the pole
keplers second law
A radius vector joining any planet to the Sun sweeps out equal areas in equal lengths of time.
