A team of theoretical physicists have discovered a strange structure in space-time that to an outside observer would look exactly like a black hole, but upon closer inspection would be anything but: they would be defects ...
Researchers have discovered a new generic production mechanism of gravitational waves generated by a phenomenon known as oscillons, which can originate in many cosmological theories from the fragmentation into solitonic "lumps" ...
A moment's hesitation... Yes, a full stop here—but shouldn't there be a comma there? Or would a hyphen be better? Punctuation can be a nuisance; it is often simply neglected. Wrong! The most recent statistical analyses ...
It looks like a black hole and bends light like a black hole, but it could actually be a new type of star.
Researchers from two laboratories at ULB have realized a synthetic dimension for light using a fiber optic ring. This ingenious system simulates the periodic motion of a particle in a crystal in order to study its behavior ...
Germany, India, Mexico, and Spain. As multiparty democracies, these countries present a more complex picture of what brings people together—or divides them. Using social media data, a group of researchers proposes a novel ...
For yet another year, the world's conference on climate change—COP27—concluded with few agreements and a clear division between North and South.
Microresonators based frequency combs, microcombs, have attracted huge interest in the last decades for their revolutionary performance of compact size, flexible comb spacing, and broad bandwidth. Wide applications of microcombs ...
We can frequently find in our daily lives a localized wave structure that maintains its shape upon propagation—picture a smoke ring flying in the air. Similar stable structures have been studied in various research fields ...
Particles of light—photons—that are forced to interact with each other through specially structured glass demonstrate behavior evocative of the "fractional quantum Hall effect," a phenomenon that garnered the 1998 Nobel ...
