Scientists Find a New Way To Hear the Faint “Ringing” of Black Holes
When two black holes collide and merge, they release gravitational waves. These waves can be detected by sensitive…
Simulations Show That Dark Matter Isn’t What Gives Stellar Streams Their Kinks
Ah, that ever-elusive dark matter. Although there has been some tantalizing evidence suggesting the detection of a dark…

46 years ago, Carl Sagan beautifully explained the fourth dimension using a sliced apple
How do you explain the concept of a fourth dimension to humans who are only able to see…
In 1972, physicists proposed hunting for gravitational waves with giant laser interferometers, and it took until 2015, after four decades of null results, for twin facilities in Louisiana and Washington to catch the ripple from two black holes colliding a billion light years away.
Picture handing your working life to an experiment that has a real chance of finding nothing at all.…

‘There is no conflict between quantum physics and gravity’: Physicists prove Einstein’s equivalence principle holds true at quantum scales
For the first time, physicists have measured the tiny quantum shift an object acquires by falling through Earth’s…
New Study Expands Search for “Dark Photons,” a Leading Dark Matter Candidate
More than fifty years after it was proposed, the search for Dark Matter continues, whether through cosmic surveys…
Physicists Determine Cause of “Runaway” Supermassive Black Hole
In September 2022, astronomers observed something very odd in a galaxy around 7.5 billion light-years from Earth. Extending…
