So cosmologists feel confident in modelling the universe using the “maximally symmetric” description of space-time in Einstein’s theory of general relativity. This symmetric vision for the universe, ...

He came up with a new one, called the Late-Transition Interacting Thawer (LTIT) model, which models how dark energy could "thaw" after a certain amount of time after the universe started and is slowly ...

“For the last 20 years, people believed that the cosmological constant is positive, and the universe will expand forever,” says Tye, a professor emeritus at Cornell. A positive constant acts like a ...
