Seeking endorsements for her new book, Chanda Prescod-Weinstein finds herself staring at fundamental questions of space, time ...

Whether space-time exists should be neither controversial nor even conceptually challenging, given the definitions of "space-time," "events" and "instants." The idea that space-time exists is no more ...

In their study, Zhao and Smalyukh created a space–time crystal in the nematic phase of a liquid crystal. In this phase the crystal’s rod-like molecules align parallel to each other and also flow like ...

“Using newer mathematical tools, my colleague and I have demonstrated a new theory that may accurately describe the universe. Instead of basing the theory on the warping of space and time, we ...

Exploring the BTZ black hole in (2+1)-dimensional gravity took me down a fascinating rabbit hole, connecting ideas I never expected—like black holes and topological phases in quantum matter! When I ...

In a new study, scientists began pondering a pretty wild question: What if black holes can convert dead star matter into dark energy, the mystery force driving the acceleration of the expansion of the ...

"We will push the limits of what we can observe, and use every gravitational lens we detect with Roman to pin down the particle nature of dark matter." When NASA’s Nancy Grace Roman Space Telescope ...

Fragments of energy may be the fundamental building blocks of the universe. The theory combines the ideas of particles and waves into a concentration of energy that flows throughout space and time.
