Today we discussed Galaxies. The immense size of these structures is breath taking. Containing hundreds of billions, if not trillions of stars and bound together with dark matter, galaxies hang in space on galactic filaments which make up the structures of the universe. How do they form ? how do they die ? why do all galaxies contain supermassive black holes at their core ? We have no idea but it’s fun to talk about.
