How the Universe Ends

Somewhere between a second and a millennium from now, you will die. Your body and all of its parts will cease functioning and rejoin the Earth as regular, lifeless stuff. The Earth, too, will die, engulfed by an expanding, ageing Sun. The Sun will burn off all of its fuel and end up a white dwarf, then burn out and die. The Milky Way will collide with nearby Andromeda, and form a large, elliptical galaxy, which will die by losing all of its stars to intergalactic space. The corpses of those remaining stars will die, decaying into their constituent parts. The universe will age onward, until all matter is either stored in black holes or floating as free elementary particles. Those black holes will evaporate, and then universe will die. All that was will be an icy cold nothing, forever. Read More >>

String Theorists’ Heads Bobble Over Potential Dark Energy Wobble

Harvard physicist Cumrun Vafa is one of string theory’s strongest proponents. But this summer, other string theorists have been reeling from his latest conjecture, which might invalidate their ideas built on a decade-long assumption that dark energy is constant. Vafa’s work implies that dark energy’s value changes. Read More >>

Synchronised Galactic Orbit Challenges Our Best Theory of How the Universe Works

Scientists thought the Milky Way and Andromeda galaxies were unique: They’ve got rings of smaller dwarf galaxies orbiting in what seems to be a synchronised fashion. But when a team of scientists recently looked at another galaxy, they realised it also seemed to shepherd a flock of dwarfs in a strange, synchronised dance. That’s not supposed to happen.

What’s the Speed of Dark Matter?

Based on physicists’ measurements, most of the mass in the universe is actually taken up by dark matter. Whatever this stuff is, we can see its effects on the behaviour of distant galaxies, though no experiment has detected it here on Earth. Doing so probably requires knowing how fast it moves.

New 3D Map of the Universe Features a Whopping 1.2 Million Galaxies

The astronomical map you see here doesn’t depict stars, it shows galaxies – 1.2 million of them, to be exact, a new record for astronomers. This extraordinary new 3D scan of the universe provides yet more evidence that a mysterious substance known as dark energy is likely causing the universe to expand at an accelerating rate.

Stunning First Images From the World’s Most Powerful Digital Camera

Sat on top of a mountain in Chile is the world's most powerful digital camera. Known as the Dark Energy Camera, it's recently been fired up to image the night sky, in an attempt to find the exotic stuff that gets all physicists excited. These are the first images it's produced. Read More >>
