  • Hubble reveals a stunning twist in how the universe emerged from darkness

    A surprising discovery by astronomers using the Hubble Space Telescope is challenging a leading explanation for how the early universe emerged from a dense fog of hydrogen roughly 13 billion years ago. Scientists once believed powerful winds from exploding stars helped radiation escape galaxies and clear that cosmic fog, but new observations reveal that these winds actually block radiation instead.
  • Physicists created a tiny universe and watched time emerge without a clock

    Scientists have created a miniature universe in the laboratory that could help answer one of the biggest mysteries in physics: What is time, and where does it come from? Using 24,000 ultracold atoms, a University of Birmingham researcher built an isolated quantum system that repeatedly expands and contracts, mimicking the Big Bang and a possible Big Crunch. Remarkably, the experiment showed that time could emerge from changes happening inside the system, without relying on an external clock.
  • Einstein's equations may explain the universe without dark energy

    Mathematicians have uncovered what they argue is a fundamental flaw in the standard model of the universe, potentially challenging the need for dark energy. Their calculations suggest that the mathematical framework used to describe cosmic expansion is inherently unstable and that the universe could accelerate naturally under Einstein's original theory of gravity. The findings also raise surprising questions about whether our location in the universe is as ordinary as scientists have long assumed.
  • NASA discovers Jupiter’s invisible shield is more complex than Earth’s

    NASA’s Juno spacecraft has discovered that Jupiter uses a surprisingly complex system of powerful plasma waves and multiple shock regions to defend against the solar wind.
