In her second pop-science book, theoretical cosmologist Chanda Prescod-Weinstein returns to her celestial and cultural roots.

Oftentimes, we think of space as an endless, mostly empty vacuum, a silent backdrop where planets, stars, and galaxies play out their dance. We also think of time as something separate, a steady ...

New spacetime model: Researchers reframed Einstein’s equations to reveal gravitational structures that can remain connected during spacetime evolution, inspired by plasma physics. Conserved quantities ...

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

Physicists have identified hidden geometric structures in spacetime that remain preserved as it evolves, revealing new ...
