“Using newer mathematical tools, my colleague and I have demonstrated a new theory that may accurately describe the universe.

Is time something that flows — or just an illusion? Exploring space-time as either a fixed “block universe” or a dynamic ...

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 and the latter a point in space, but in both cases the normally ...

Scientists have captured the clearest signal yet of a black hole collision, confirming Stephen Hawking's theory.

A radical new theory regarding the origin of the universe suggests that gravitational waves, tiny ripples in spacetime first ...

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 ...

"The singularity is the most mysterious and problematic part of a black hole. It's where our concepts of space and time literally no longer make sense." A team of scientists has developed a recipe for ...

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 ...

A new theory of the fabric of the universe has proposed that time has three dimensions. Moreover, this model leads to the conclusion that these three time dimensions are the true underlying feature of ...

If you wave your hand in front of your face, you won’t notice anything particularly interesting. Perhaps a gentle waft of air against your cheek – that’s about it. No epiphany. No major sign that ...

Knowledge space theory (KST) provides a rigorous mathematical framework to represent an individual’s knowledge state as a collection of items or skills that have been mastered. This framework, which ...
