UBC physicists may have solved one of nature’s great puzzles: what causes the accelerating expansion of our universe? PhD student Qingdi Wang has tackled this question in a new study that tries to resolve a major incompatibility issue between two of the most successful theories that explain how our universe works: quantum mechanics and Einstein’s theory of general relativity. The study suggests that if we zoomed in-way in-on the universe, we would realize it’s made up of constantly fluctuating space and time.

“Space-time is not as static as it appears, it’s constantly moving,” said Wang...
