Researchers often cite the whirlpool of activity generated by matter spiraling into supermassive black holes ó which weigh millions to billions of times the sunís mass and sit at the cores of galaxies ó to explain why star formation halts and galaxies never exceed a maximum size. Models suggest that fierce winds or powerful radio jets produced as black holes pull in new material can warm up or even expel cold gas, keeping galaxies from growing bigger and depleting them of the raw material for making stars.

"Invisible Pink Unicorns are beings of great spiritual power. We know this because they are capable of being invisible and pink at the same time. Like all religions, the Faith of the Invisible Pink Unicorns is based upon both logic and faith. We have faith that they are pink; we logically know that they are invisible because we can't see them."
