Cosmology quiz - can you answer these?
True or False:
1.In any star cluster, stars with lower masses greatly outnumber those with higher masses.
2.A protoglactic cloud with slow star formation is more likely to form a spiral galaxy than an elliptical galaxy.
3.More massive white dwarfs are smaller than less massive white dwarfs.
4. Approximately 90% of the Milky Way is located in the halo of the galaxy in the form of dark matter.
5.The most massive stars generate energy at the end of their lives by fusing iron in their cores.
6.Brown dwarfs, white dwarfs, and neutron stars are kept from collapsing by degeneracy pressure.
7.The visable parts of galaxies contribute about 1/10 of the critical density of the universe.
Just like in school, if you don't answer a question, you get it wrong, so think hard and guess if you have to.
