Magnetar flares, colossal cosmic explosions, may be directly responsible for the creation and distribution of heavy elements across the universe, suggests a new study. Magnetar flares, colossal cosmic ...

What is dark energy? Why does dark energy seem to be weakening? Is our universe part of a larger multiverse? What lies beyond the boundary of a black hole? The universe seems to be rotating, and if ...

(via Sabine Hossenfelder) Physicists have a lot of questions about our universe. Here’s one more to add to the list: Why is it so asymmetrical? New research has confirmed an anomaly named the ...

If you think a galaxy is big, compare it to the size of the Universe: it’s just a tiny dot which, together with a huge number ...

The universe is poised to die much faster than previously thought, according to new research by Dutch scientists. But there's no great need to panic. We still have 10 to the power of 78 years before ...

We can never 100% prove that the constants really are constant. There is a set of very special numbers, known as the fundamental constants of nature, that cannot be explained. Where do they come from?
