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, Noble 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, about new Hubble Space Telescope data that suggest 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.
An unknown object, perhaps a cosmic string, was detected at the Milky Way’s galactic center in 2016 that could have profound implications for understanding gravity, space-time and the Universe itself. Cosmic strings, galaxy-sized filaments of raw energy, may be threaded through spacetime, according to some theories. At the Big Bang, our universe exploded into being, expanded at a fantastic speed and cooled perhaps cracking the fabric of the universe with hairline fractures.
