Researchers have found a link between some of the largest and smallest objects in the cosmos: supermassive black holes and dark matter particles. Their new calculations reveal that pairs of ...

For more than a century, physics has been built on two great theories. Einstein's general relativity explains gravity as the bending of space and time. Subscribe to our newsletter for the latest ...

Supermassive black holes (SMBHs) can have billions of solar masses, and observational evidence suggests that all large galaxies have one at their centers. However, the JWST has revealed a foundational ...

One of the big mysteries of the universe is how it's expanding. The phenomenon causing that expansion is known as dark energy — and recently, scientists have started to wonder if its changing. Now let ...

A new theory claims dark matter and dark energy don’t exist — they’re just side effects of the universe’s changing forces. By rethinking gravity and cosmic timelines, it could rewrite our ...

Supermassive black holes (SMBHs) are the churning engines of galaxies, but astrophysicists aren’t exactly sure how two of them merge. While evidence suggests this occurs, we’ve never seen a merger ...

Our current cosmological model—known as lambda cold dark matter, or ΛCDM—relies on hypothesized dark energy to explain the accelerating expansion of the universe. However, one competing theory known ...

David Weinberg receives funding from the National Science Foundation and NASA that supports his dark energy research. Ashley Ross receives funding from Lawrence Berkeley National Lab to support his ...

For more than a century, physics has been built on two great theories. Einstein's general relativity explains gravity as the bending of space and time. Quantum mechanics governs the world of particles ...

Simulation of the light emitted by a supermassive black hole binary system where the surrounding gas is optically thin (transparent). Viewed from 72 degrees inclination, or partially angled above the ...
