Mysterious 'kick' just after the Big Bang may have created dark matter

By Paul Sutter Published

A mysterious "kick" in the early universe may have produced more matter than antimatter. And that imbalance may have also led to the creation of dark matter, researchers now say.

Scientists have taken a fresh look at the universe to determine its age, settling old debates.
Astronomers reevaluate the age of the universe

By Chelsea Gohd Published

Scientists have taken a fresh look at the observable (expanding) universe and have estimated that it is 13.77 billion years old (plus or minus 40 million years).

Strands in the intergalactic web

Astronomy
Observations made with the European Southern Observatory’s Very Large Telescope in Chile have revealed for the first time that a star orbiting the supermassive black hole at the center of the Milky Way moves just as predicted by Einstein's theory of general relativity. Its orbit is shaped like a rosette and not like an ellipse as predicted by Newton's theory of gravity. This effect, known as Schwarzschild precession, had never before been measured for a star around a supermassive black hole. This artist's impression illustrates the precession of the star's orbit, with the effect exaggerated for easier visualization.
What's the most amazing thing about the universe?

By Paul Sutter Published

A few scant equations can explain a variety of phenomena in our universe, over vast gulfs of space and time. Here's a taste of just how powerful modern physics can be.
