Astronomers may have misread cosmic acceleration for 27 years. The universe may be slowing down, not speeding up.

The universe's expansion may actually have started to slow rather than accelerating at an ever-increasing rate as previously ...

New supercomputer simulations hint that dark energy might be dynamic, not constant, subtly reshaping the Universe’s structure. The findings align with recent DESI observations, offering the strongest ...

Dark energy is one of the greatest mysteries of the universe. This mysterious force is thought to be accelerating the expansion of the cosmos. But a new study challenges this long-held belief. A team ...

Dark energy and black holes are two of the most mysterious topics when it comes to space, but they might actually be linked.

A new study is implying that the universe may actually be slowing down and that the culmination of the decrease in dark ...

A new study using the Dark Energy Survey (DES) final datasets suggests potential inconsistencies in the standard cosmological model, known as ΛCDM. If confirmed, these findings could fundamentally ...

Dark energy does not exist, some scientists have claimed – which could help get rid of one of the universe’s biggest mysteries. For a century, scientists have thought that the universe was expanding ...

A project to discover the nature of dark energy, a mysterious force causing the expansion of the universe to speed up, has received an $8 million grant from the National Science Foundation (NSF). The ...

BERKELEY, CA — The National Research Council’s Beyond Einstein Program Assessment Committee has recommended that the Joint Dark Energy Mission (JDEM), jointly supported by the National Aeronautics and ...

Dark energy, a mysterious force that scientists believe is behind the accelerated expansion of the universe, is weakening — which could result in the universe over the course of billions of years ...

Rossana Ruggeri is the recipient of an Australian Research Council (ARC) Discovery Early Career Researcher Award (DECRA), which supports her independent research project titled "Probing Dark Energy ...
