Scientists in Greece have laid out a mathematical framework to help explain a so-far-unsolved gap in our understanding of how ...

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 ...

Is 3I/ATLAS 'alien tech'? Harvard's Avi Loeb details 8 anomalies, including a Jupiter trajectory that 'defies spacetime,' as the object faces its 'acid test' at perihelion.

Physicists have recently proposed a radical idea that challenges our understanding of the universe. They suggest that spacetime, a fundamental concept in physics, may be an illusion emerging from ...

Forbes contributors publish independent expert analyses and insights. The Universe is out there, waiting for you to discover it. The biggest lesson from Einstein's general theory of relativity is that ...

A team of cosmologists in Finland and Poland have proposed that the accelerated expansion of the universe, usually explained by dark energy, may actually be the result of "Tardis regions" of spacetime ...

What if spacetime were a kind of fluid? This is the question tackled by theoretical physicists working on quantum gravity by creating models attempting to reconcile gravity and quantum mechanics. Some ...

Satellite operator Telesat plans to use Aalyria’s Spacetime networking tech for its Lightspeed satellite constellation. Spacetime tries to find the best route for customer data between any two points ...
