Hubble constant. The Hubble constant is crucial in understanding the rate of expansion of the universe and, by extension, estimating the universe’s age. This collaborative effort unites various ...

“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 ...

The “horizon” he points to isn’t a doorway to the divine, other scientists say. Yet, modern physics has been trying to answer questions once left to religion.

The shape of the cosmos depends on a balance of two competing forces: the pull of gravity and the expansion driven by dark ...

A physicist proposes that the universe might not be empty but act like a viscous fluid, resisting expansion. This bold idea ...

Physicist Sean Carroll explains how physics, astronomy, philosophy, and classics all help us understand the expanding ...

The fate of the cosmos may be a bit different than previously expected. For years, scientists have talked about how the universe is always expanding — constantly moving outward, never stopping.

This breathtaking clue about the architecture of consciousness supports a Nobel-Prize winner’s theory about how quantum physics works in your brain.

Now physicists from the University of Washington are taking a big swing at answering that question. All matter exerts gravitational force. The more mass the object has, the greater the force. Yet, a ...

Researchers at the University of British Columbia Okanagan have published a mathematical argument that, they say, rules out ...
