1. Which description best summarizes the steps that take place during black hole formation, in the correct order?
Supernova explodes a massive star; remaining core expands; nuclear reactions diminish the effects of gravity.
Supernova triggers fusion reactions; massive star implodes due to extreme radiation; volume and mass of star increase rapidly.
A massive star depletes its nuclear fuel; gravity overpowers the star; supernova occurs; core of star collapses.
A small star gains mass through fusion reactions; core of star collapses; increased radiation triggers a supernova.
2. Astronomers think that most galaxies are centered by a (nebula, large planet, black hole, massive star), which exerts (centripetal force, magnetic pull, gravitational pull, centrifugal force) that binds the galaxy together.
3. Where would scientists look to observe a black hole?
The center of the Milky Way
The center of the sun
The solar system asteroid belt
The edge of the solar system
