Answer 1

Answer:

What is the nature of the dark energy that drives cosmic acceleration?

If you think dark matter is frustrating, try explaining dark energy. Something is driving space to expand at an ever increasing rate. Physicists think that they know what it is — the never-changing density of energy residing throughout all of space, referred to by Einstein as the “cosmical term” and now called the cosmological constant. But when you calculate how strong the cosmological constant should be, the answer is too big by dozens of orders of magnitude — much more than the difference between the size of the entire universe compared with a proton. So dark energy’s identity remains a mystery; if it is the cosmological constant, something else is seriously wrong with what physicists think they know. And so far game theory has been absolutely no help.
