Dark matter has two central properties: it has mass like regular matter, and unlike regular matter, it reacts weakly or not at all with light. Neutrinos satisfy these two criteria, but neutrinos move ...

The nature of dark matter remains one of the greatest mysteries in cosmology. Within the standard framework of non-collisional cold dark matter (CDM), various models are considered: WIMPs (Weakly ...

Astrophysicists at the University of Chicago have developed physics-based models suggesting that dark energy could be changing over time. Dark energy, the mysterious force causing the universe to ...

Such an exponential expansion may seem minor, but it is equivalent to a grape in the palm of your hand swelling to become ...

Dark matter remains one of the most compelling enigmas in modern cosmology. Although it does not emit light, its gravitational influence is essential for the formation and evolution of cosmic ...

One of the biggest mysteries in astrophysics today is that the forces in galaxies do not seem to add up. Galaxies rotate much faster than predicted by applying Newton’s law of gravity to their visible ...

Despite it’s comparative size to our star, it’s still the least massive object ever detected using gravitational lensing.

Evidence of this quantum layer may be coming soon. Here’s what you’ll learn in this story: Physicists are still puzzling over ...

Our common understanding of the universe tells us that all matter and energy were created at the beginning of time during a period of rapid inflation called the Big Bang. However, in 2023, Katherine ...

Rajendra Gupta receives unconditional research funding from Macronix Research Corporation. He is affiliated with the American Physical Society, Royal Astronomical Society, European Astronomical ...

Astronomers determined in 1929 that the universe is expanding. This was one of the most important findings in science. In 1998, two separate groups of astrophysicists discovered that the universe’s ...
