Regions of space you fall into and you donโt come out of? Black holes. Big red stars? Red giants. So I take my fellow scientists to task. Heโll use his word, and if I understand it, Iโll say, โOh, does that mean da-da-da-de-da?

The man was connected to the universe in spooky ways. He discovered the laws of motion, the laws of gravity, the laws of optics. Then he turned 26.
