How confusing inevitability with reality built decades of paradox. What if general relativity never actually tells us that ...

A new study by researchers at the University of Amsterdam shows how gravitational waves from black holes can be used to ...

For close to a century, scientists have been trying to marry Albert Einstein’s General Theory of Relativity and quantum ...

Breakthroughs in science often begin with a simple question and years of tireless exploration. From the way tiny molecules slip through microscopic pores to the staggering behavior of matter near ...

When black holes need a place to crash, they prefer a nice, bright quasar. So says Chiara Mingarelli, an assistant professor of physics in Yale’s Faculty of Arts and Sciences and a key member of an ...

Our universe may have been born in a gravitational crunch that formed a very massive black hole—followed by a bounce inside it. The Big Bang is often described as the explosive birth of the universe—a ...

In the early universe, moments after the Big Bang and cosmic inflation, clusters of exotic, massive particles could have ...

In a single decade, we have gone from the first-ever gravitational wave detection to several hundred of them. Every time there is a new possible detection, an alert is sent out, so observatories ...

The Hubble Space Telescope has recently captured extraordinary images of a rapidly collapsing star system in the Andromeda Galaxy. This discovery offers a unique glimpse into stellar evolution and the ...

Using various ground-based and space telescopes, an international team of astronomers has observed a recently discovered fast ...
