Astrophysicists at the University of Chicago have developed physics-based models suggesting that dark energy could be ...

New strategies may soon allow scientists to test dark energy theories within our own solar system, linking cosmic-scale physics to local observation. Science advances through a cycle of proposing ...

The universe's expansion may be accelerating faster than previously thought. Dark energy, a mysterious force, might not be constant but could be changing over time. Multiple independent studies show ...

The birth, growth and future of our universe are eternally fascinating. In the last decades, telescopes have been able to observe the skies with unprecedented precision and sensitivity. Our research ...

According to the model, dark matter may have started as particles that were hot, light, massless, and fast. As the universe ...

An artist’s concept of the dark energy-driven accelerating expansion of the universe. New results suggest dark energy’s influence on cosmic expansion has weakened over time. In 2024 a shockwave ...

In 2024 a shockwave rippled through the astronomical world, shaking it to the core. The disturbance didn’t come from some astral disaster at the solar system’s doorstep, however. Rather it arrived via ...

Last year, we reported on an exciting hint of new physics in the first data analysis results from the Dark Energy Spectroscopic Instrument (DESI)—namely that the dark energy, rather than being ...

In early 2024, McGill University doctoral student Vishwangi Shah and her colleagues were conducting a routine review of data from the Canadian Hydrogen Intensity Mapping Experiment when they noticed ...
