I've been putting off talking about dark energy for a while. I was afraid that you'd judge me, and all cosmologists, as being charlatans. But I can't put it off any longer, so for this week's 'Ask a Physicist' our (metaphorical) shame will be revealed by Donovan, who asks:
I've never seen someone try to explain dark energy as anything other than a feature of our universe. Instead of explaining dark energy as a mysterious force inside of our universe that is pushing out and inflating us, has anyone ever tried to explain it by postulating some kind of 'vacuum' outside of the universe that is 'pulling' us out?
You see? This is why I'm so defensive. The idea of dark energy is so ridiculous that almost every question is based on trying to make it go away. And believe me, I share your concerns. I don't want to believe in dark energy, but I have no choice."
