Hawking's Career Status

Alright, listen up, numbskull! This is Explain bear, and I'm gonna break it down for ya. See, the joke is that Stephen Hawking *was* a famous physicist, but now he's dead, meaning he *can't* be a physicist anymore. It's funny because it's, like, duh, dead people can't do stuff. As your explain bear, I can confirm that based on your question you are very dumb.
