In a galaxy far away, two dead stars begin a final spiral into a massive collision. The resulting explosion unleashes a huge burst of energy, sending ripples across the very fabric of space. In the nuclear cauldron of the collision, atoms are ripped apart to form entirely new elements and scattered outward across the Universe.
Some of the biggest names in science took part in a special public event yesterday (2 July) to celebrate the life and work of Stephen Hawking, on the occasion of his 75th birthday.
Researchers have shown how singularities – which are normally only found at the centre of black holes and hidden from view – could exist in highly curved three-dimensional space.
With its very first – and last – observation, the Hitomi x-ray observatory has discovered that the gas in the Perseus cluster of galaxies is much less turbulent than expected, despite being home to NGC 1275, a highly energetic active galaxy.
Researchers have successfully simulated how a ring-shaped black hole could cause general relativity to break down: assuming the universe contains at least five dimensions, that is.
New window on the universe is opened with the observation of gravitational waves – ripples in spacetime – caused by the collision of two black holes.
Watch speakers such as Stephen Hawking and Brian Cox this evening as the public symposium of the 17th International Conference on Particle Physics and Cosmology, known as COSMO 2013, is broadcast live on YouTube.
