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 of other tiny dots, forms clusters that aggregate into superclusters, which in turn weave into ...
Dark energy—the term used to describe whatever is causing the universe to expand at an increasing rate—is one of the universe's greatest mysteries. The most widely accepted theory currently suggests that dark energy is constant, ...
LIGO, the Laser Interferometer Gravitational-wave Observatory, has been called the most precise ruler in the world for its ability to measure motions more than 10,000 times smaller than the width of a proton. By making these ...
An international team of researchers has announced a significant advancement in gravitational-wave astronomy, with the detection of 128 new cosmic collisions involving black holes and neutron stars.
To study the origin and evolution of the universe, physicists rely on theories that describe the statistical relationships between different events or fields in spacetime, broadly referred to as cosmological correlations. ...
These are exciting times to explore the largest unanswered questions in physics thanks to high-tech experiments and very precise data. That's particularly true of dark energy, the name given to the mysterious driver of the ...
We're often told it is "unscientific" or "meaningless" to ask what happened before the Big Bang. But a new paper by FQxI cosmologist Eugene Lim, of King's College London, UK, and astrophysicists Katy Clough, of Queen Mary ...
An international team of astronomers led by Matus Rybak (Leiden University, Netherlands) has proven, thanks to accidental double zoom, that millimeter radiation is generated close to the core of a supermassive black hole. ...
A University of Queensland researcher has developed a new mathematical model to explain the evolution of the universe which, for the first time, includes collapsing regions of matter and expanding voids.
Supernovae appear to our eyes—and to astronomical instruments—as brilliant flashes that flare up in the sky without warning, in places where nothing was visible just moments before. The flash is caused by the colossal explosion ...
