A new Big Bang model does away with speculative elements, putting gravitational waves at the forefront of the creation of ...

Fragments of energy may be the fundamental building blocks of the universe. The theory combines the ideas of particles and waves into a concentration of energy that flows throughout space and time.

Two black holes collided 1.3 billion light years from Earth, creating a 'ringing,' which in turn allowed astrophysicists to ...

The idea was first hypothesized about 70 years ago. In a bizarre repercussion of Albert Einstein's Special Theory of Relativity, objects traveling close to the speed of light appear flipped over. The ...

IUCAA scientist explains gravity, gravitational waves to students at SRM University-AP outreach event, featuring academic sessions and hands-on experiments.

A fringe new theory suggests that time is the fundamental structure of the physical universe, and space is merely a byproduct. According to Gunther Kletetschka, a geologist — not a physicist, you'll ...

Exploring the BTZ black hole in (2+1)-dimensional gravity took me down a fascinating rabbit hole, connecting ideas I never expected—like black holes and topological phases in quantum matter! When I ...

"It may take decades before we find out what really happens in black holes." Reports of the singularity's demise may have been premature. Earlier this year, new research suggested a potential solution ...

The original version of this story appeared in Quanta Magazine. Two blind spots torture physicists: the birth of the universe and the center of a black hole. The former may feel like a moment in time ...

Time, not space plus time, might be the single fundamental property in which all physical phenomena occur, according to a new theory by a University of Alaska Fairbanks scientist. The theory also ...
