Scientists have compiled 25 of the most perplexing space phenomena that continue to defy explanation, from interstellar visitors like ʻOumuamua to the unexplained dimming of Betelgeuse. These ...

A detector buried deep in Antarctic ice has captured the first experimental evidence of a predicted but never-before-seen ...

Gravity, as most people understand it, is the familiar force that pulls a falling apple toward Earth. But for astronomers and theoretical physicists, it is also a vexing invisible architect that ...

We all know that everything kicked off when the Big Bang exploded our universe into reality, right? Well, not necessarily. A compelling new theory of the creation of our universe suggests that it may ...

For the last several years, cosmology – the study of the universe as a whole – has been facing a major tension. The two main approaches to measure the expansion of the universe today should give us ...

Wormholes may help solve a major physics paradox, the conflict between quantum mechanics and general relativity. The “direct-sum quantum theory” views spacetime as distinct but related regions.

Astronomers are rethinking one of cosmology’s biggest mysteries: dark energy. New findings show that evolving dark energy models, tied to ultra-light axion particles, may better fit the universe’s ...

Black hole discovery reshaped astrophysics by proving that some of the universe's most powerful objects cannot be seen directly but can be measured through their effects on space and time. Signals ...

Gravity is so weird that it essentially forces cosmologists into subscribing to one of two equally radical conclusions: dark matter exists, or fundamental gravity rules need massive revisions. To ...
