3 - 100 n A star is born when what begins? n Hydrogen fusion

3 - 200 n The core of MASSIVE stars get hot enough that they can fuse elements as large as what? n Iron

3 - 300 n Massive stars become ____ then a supernova occurs and they become _____ or ____ n Supergiants, neutron stars or blackholes

3 - 400 n Why is a black hole black? n Light can’t escape its pull of gravity

5 - 400 n Why was Leviticus burned to death? n Questioning the church and stating that the universe was limitless

5 - 500 n Explain the Doppler effect and the universe. The Doppler effect states that as light comes towards you its frequency increases and as it moves away from you its frequency decreases. The universe gives a red shift because the light is moving away from us – because the galaxy is expanding
