The LISA (Laser Interferometer Space Antenna) observatory, now in development, will detect gravitational waves, the tiny ...

Spacetime isn’t something that exists; it’s a model for describing how events happen. Treating events as objects creates philosophical confusion and fuels misconceptions, such as time-travel paradoxes ...

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 ...

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 ...

Nov. 10, 2026 A breakthrough in telescope imaging could reveal countless alien worlds that have been hiding in plain sight. Scientists developed a new technique that uses a digital twin of the James ...

Einstein’s equations suggest that gravity may be capable of a process resembling the one behind powerful solar explosions. In a new theoretical study, physicists show how gravitational field ...

The September read for the New Scientist Book Club was a challenging trip to the edges of space-time with Chanda Prescod-Weinstein – but one which most book club members thoroughly enjoyed ...

In 1973, John Archibald Wheeler described the relationship between space and matter in two sentences: “Space acts on matter, telling it how to move. In turn, matter reacts back on space, telling it ...

For over a century, Einsteins equations have described how mass and energy curve spacetime, giving rise to gravity. But where do these equations actually come from, and could they be a consequence of ...
