Controversial Theory Says Expansion of Universe Is Driven by Quantum Fluctuations

A team of researchers from the University of British Columbia, Canada, has proposed a radical new theory about the expansion of the universe. Scientists do not know exactly why the universe is expanding at an ever-accelerating pace, but the most popular theory is that this growth is being driven by dark energy, the theoretical force thought to make up 68 percent of the universe.However, the University of British Columbia researchers have another theory—that quantum fluctuations of vacuum energy are responsible.Scientists discovered the universe is expanding at an accelerating rate in 1998. Researchers analyzed the light from supernovae (exploding stars) and discovered the supernovae were moving away from each other at an ever increasing speed. They concluded the universe must be expanding at an accelerating rate.
