Why do the numbers that shape our universe exist at all?
There is a set of very special numbers, known as the fundamental constants of nature, that cannot be explained. Where do they come from?
The physics of the universe appear to be fine-tuned for life. Why?
The physical constants of the universe appear to favor the existence of life. So why are we here?
The Mystery of How Supermassive Black Holes Merge
The giant holes in galaxies’ centers shouldn’t be able to combine, yet combine they do. Scientists suggest that an unusual form of dark matter may be the solution.
The usual way of hunting dark matter may be all wrong
If dark matter isn't heavy and interacts even weakly with normal matter, we should drag our detectors out from underground to catch it
Why Hawking’s PhD thesis is now an internet-breaking inspiration
Millions rushed to freely access Stephen Hawking's early musings when they went online. More of the same would help ignite young minds everywhere, says Geraint Lewis
Latest gravitational wave isn’t from neutron stars after all
Recent speculation about the latest gravitational wave experiments suggested they may have seen a neutron star merger, but it’s another black hole smashup
Infamous three-body problem has over a thousand new solutions
A long-standing maths puzzle has 1223 new solutions, more than doubling the number of possible paths three objects can take as they orbit one another
The sun just belched out the strongest solar flare in 12 years
If your GPS has been acting funny, take it up with the sun. Our star has released the most powerful solar flare since 2005
Hidden pockets of turbulent gas fuel stars in far-off galaxies
Galactic winds once thought to slow star formation may be driving the creation of new stars in distant galaxies, challenging long held believes about galaxy evolution
We’ve just seen 15 new mysterious cosmic radio bursts from space
Breakthrough Listen detected more radio pulses from the famous repeating source FRB 121102. They’re higher frequency than previous ones but we still don’t know what causes them
