A bold new idea aims to link two famously discordant descriptions of nature. In doing so, it may also reveal how space-time owes its existence to the spooky connections of quantum information.

Independent scientists have cast serious doubt on a claimed detection of dark matter.

New observations could help us understand discrepancies in measurements of the expansion of the Universe.

If dark energy is just a grand illusion – as some suggest – then rethinking our interpretation of the basic principles of general relativity in a complex universe is crucial.

Over the 20th century our knowledge of the universe expanded, as did our technological ability to capture images its outer reaches. The Hubble Space Telescope allowed us to pull back the curtains on the deep limits of the universe and the new millennium promises an even higher definition imaging with the James Webb Space Telescope.

Despite ongoing delays, the JWT promises to take us even closer to the edge of time and space, delivering a new perspective on some of the oldest galaxies in the universe, potentially just a few hundred million years after the big bang.

Scientists at LIGO detected billion-year-old gravitational waves, and they are expecting to detect a lot more. This is an excerpt from ‘The Little Book of Black Holes’ by Frans Pretorius and Steven S. Gubser, reprinted with permission from the publisher Princeton University Press.

A black hole could strip your past and give you infinite futures, according to a new study.

In principle, a wormhole-like scenario is possible, but a wormhole tends to close before objects or other matter could pass through it. As far as we know, it’s unlikely we could construct a wormhole that stays open long enough for us to get to a distant part of the universe.

That’s really the issue: Can you keep a wormhole open?
