Welcome to the biggest mystery in physics: one of the great known unknowns of the universe is the nature of dark energy, an antigravitaional force field making the universe expand faster. Current theories range from end-of-the universe scenarios to dark energy as the manifestation of advanced intelligent life. It is the proverbial elephant in the “cosmic” room. (more…)
Two of the planet’s leading astrophysicists, Columbia University’s Caleb Scharf and Harvard’s Lisa Randall speculate about the possibility of the dominant dark side of our universe harboring advanced life.
In an interview with The Atlantic, Nobel-Prize winning physicist Adam Riess said: “I have absolutely no clue what dark energy is. Dark energy appears strong enough to push the entire universe – yet its source is unknown, its location is unknown and its physics are highly speculative.”

“The Hubble tension between the early and late universe may be the most exciting development in cosmology in decades,” says Nobel laureate Adam Riess of the Space Telescope Science Institute (STScI) and Johns Hopkins University. New Hubble Space Telescope data suggests a faster expansion rate in the modern universe than expected based on how the universe appeared more than 13 billion years ago, strengthening the case that new theories may be needed to explain the dark energy forces that have shaped the cosmos.
