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

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 ...

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 ...

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

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

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.

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

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.

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 ...
