“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 fabric reveals deeper mysteries about existence, change, and the very nature of ...

For scientists, learning more about how black holes behave is essential to understanding how the universe works. A recent ...

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 ...

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 ...

"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 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 ...

Ten years after scientists first detected gravitational waves emerging from two colliding black holes, the LIGO-Virgo-KAGRA ...

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 ...
