I have a question about GR in a cosmological setting. If dark energy is assumed to be a true GR cosmological constant, does this require some kind of energy input. I am curious to know if this is just a 'curvature' of space somehow, or does it represent a continual addition of energy on some level? I'm curious to know if energy is being created somehow. Also, is this energy negative or positive? Thanks!(adsbygoogle = window.adsbygoogle || []).push({});
