One such mystery, described in a recent paper in The Astrophysical Journal Letters, concerns circumbinary exoplanets—or rather, the shortage thereof—in the now 6,000+ exoplanets confirmed to date.

The team examined the remnant black hole’s “Kerr nature”, the mathematical description of a rotating black hole in general relativity. By analyzing the dominant quadrupolar mode and its overtone, they ...

LIGO's GW250114 signal tests Einstein's relativity, revealing black hole properties and confirming key theorems in ...

Friedmann accepted this new term but pointed out a radical alternative: the universe did not have to be frozen. He argued that Einstein’s static universe was merely a special case and that the cosmos ...

Astronomers have found thousands of exoplanets around single stars, but few around binary stars—even though both types of stars are equally common. Physicists can now explain the dearth.

Dr. Leonardos Gkouvelis, researcher at LMU's University Observatory Munich and member of the ORIGINS Excellence Cluster, has ...

A hundred years ago this week, at the height of the quantum revolution, Austrian physicist Erwin Schrödinger submitted a ...

Physicists long believed time was a basic feature of the universe. But it may just emerge from cosmic information.

A century ago, Erwin Schrödinger came up with an equation that says how the quantum world behaves. Now scientists are asking ...

Abstract: Mission engineering (ME) is an emerging approach to designing and analyzing configurations of system-of-systems (SoS) for accomplishing one or more missions. ME seeks to flexibly leverage ...

Vladimir Fock occupies a distinctive place in the history of twentieth-century science, not only for his profound ...
