“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 ...

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

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 ...

The Universe may not have started with the Big Bang, but instead “bounced” out of a massive black hole formed within a larger “parent” universe, according to a new scientific paper. Professor Enrique ...

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

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

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

New data from major dark-energy observatories suggest the universe may not expand forever after all. A Cornell physicist calculates that the cosmos is heading toward a dramatic reversal: after ...

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 ...

There is a new exhibit at the University of Arizona Flandrau Science Center and Planetarium: Universe of Science. It features a variety of interactive activities for people of all ages to learn about ...
