The Black Hole at the Beginning of Time
Is the big bang, and all that came from it, a holographic mirage from another dimension?
Features
Superstars of the First Galaxies
Emerging evidence suggests that the first starlight to shine after the big bang’s flash came from distant suns that ranged from very large to incredibly huge
Fiery Holes in Space and Time
Firewalls” of particles may border black holes, confounding both general relativity and quantum mechanics
Can Time Travelers Reach the Past via Wormholes?
Astronauts already skip ahead in time, but the laws of physics seem to forbid going backward—or do they?
Giant Bubbles Soar over the Milky Way
Newly discovered lobes stretch tens of thousands of light-years above and below the Milky Way's disk. Where did they come from?
South Pole Experiment Traps Neutrinos from Beyond the Galaxy
Dozens of particles from halfway across the universe have landed in the IceCube experiment. These messengers could help answer some long-standing cosmic conundrums

Imagine if space were 2-D rather than 3-D. How would the force of gravity work? The surprising answers are guiding physicists to a unified theory of nature
New Physics Questions the Very Nature of Reality
Physicists speak of the world as being made of particles and force fields, but it is not at all clear what particles and force fields actually are in the quantum realm. The world may instead consist of bundles of properties, such as color and shape...
