Time dilation is one of the most intriguing concepts in Einstein's theory of relativity, fundamentally altering our understanding of time and space. It refers to the phenomenon where time appears to pass at different rates for observers in different frames... Continue Reading →
Is our universe haunted? It might look that way on this dark matter map. The gravity of unseen dark matter is the leading explanation for why galaxies rotate so fast, why galaxies orbit clusters so fast, why gravitational lenses so strongly deflect light, and why visible matter is distributed...

Supercomputer simulations of galaxies have shown that Einstein's theory of General Relativity might not be the only way to explain how gravity works or how galaxies form. Physicists at Durham University, UK, simulated the cosmos using an alternative model for... Continue Reading →
A new study by a pair of researchers in the US and Japan has found that, when gravity is combined with quantum mechanics, symmetry is not possible. "Many physicists believe that there must a beautiful set of laws in Nature... Continue Reading →
