At the heart of every black hole sits a problem. As they sizzle away into nothingness over the eons, they take with them a small piece of the Universe. Which, quite frankly, just isn't in the rule book.

12 billion light years from Earth, scientists spotted a galaxy that is the spitting image of a young Milky Way. Its discovery challenges our understanding of the early universe.

A physicist slams hype about multiverses, string theory, and quantum computers and calls for more diversity in his field

A conscientious cosmologist rejects Einstein’s notion that time is an illusion and the future is set

New measurements could upend the standard theory of the cosmos that has reigned since the discovery of dark energy 21 years ago.

New research suggests that the Big Bang that birthed the cosmos occurred 12.5 billion years ago.

Data from the Gaia spacecraft are radically transforming how we see the evolution of our Galaxy. By Adam Mann.

A team of scientists have detected the gravitational waves that resulted from the largest collision of black holes ever observed and that formed a new black hole about eighty times larger than the sun. This and 3 other black hole fusions were detected by an international team of scientists formed by the Advanced laser interferometer Gravitational-Wave Observatory (LIGO) in the U.S. and the Australian National University (ANU) in Canberra, Efe news reported on Tuesday.

They seem to reverse time. By Yasemin Saplakoglu.

The multiverse theory says our universe is one of many in an infinite multiverse where new universes are always being born. It's thought these baby universes would have a wide range of physical laws, making few hospitable for life, but new research suggests the multiverse may be friendlier to life than expected.

From quantum physics to the anti-rationalism of Thomas Kuhn. By Tim Maudlin.

In an era when untestable ideas such as the multiverse hold sway, Michela Massimi defends science from those who think it hopelessly unmoored from physical reality. By Philip Ball.

From a childhood hallucination to the halls of theoretical physics. By Alan Lightman.

Andrew Jaffe probes Carlo Rovelli’s study arguing that physics deconstructs our sense of time.

In a study published March 14 in The Monthly Notices of the Royal Astronomical Society, astronomers announced the discovery that all galaxies rotate about once every billion years, no matter their size.

A new measurement of how fast the universe is expanding reveals an odd gap.

Hello darkness my old friend. By Mike McRae.

Distances in the expanding Universe don’t work like you’d expect. Unless, that is, you learn to think like a cosmologist.
