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.

Beyond the Milky Way: The sublime beauty of our galactic neighbors
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.
Study Suggests You Can Survive Certain Black Holes
A black hole could strip your past and give you infinite futures, according to a new study.
Blue Sky Science: Are there wormholes that lead to other galaxies?
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?
Wormholes can exist even at the quantum level, which is a very small scale, smaller than an atom. Trying to move matter through a wormhole at the classical level, the large-size level, is where it gets trickier.
The Most Precise Measurement of Antimatter Yet Deepens the Mystery of Why We Exist
Scientists have made the most precise measurement of antimatter yet, and the results only deepen the mystery of why life, the universe, and everything in it exists.
The new measurements show that, to an incredibly high degree of precision, antimatter and matter behave identically.
Yet those new measurements can’t answer one of the biggest questions in physics: Why, if equal parts matter and antimatter were formed during the Big Bang, is our universe today made up of matter?
