A new theory of quantum gravity could explain the biggest puzzle in cosmology, study suggestsA new theory of quantum gravity, which attempts to unite quantum physics with Einstein's relativity, could help solve the puzzle of the universe's expansion, a theoretical paper suggests.

Black hole singularities defy physics. New research could finally do away with them.Black hole singularities defy the laws of physics. New research presents a bold solution to this puzzle: Black holes may actually be a theoretical type of star called a 'gravastar,' filled with universe-expanding dark energy.

Tweak to Schrödinger's cat equation could unite Einstein's relativity and quantum mechanics, study hintsPhysicists have proposed modifications to the infamous Schrödinger's cat paradox that could help explain why quantum particles can exist in more than one state simultaneously, while large objects (like the universe) seemingly cannot.

Mysterious 'unparticles' may be pushing the universe apart, new theoretical study suggestsNew theoretical research suggests that a mysterious form of matter called "unparticles" could be the driving force behind the expansion of the universe.

Our universe is merging with 'baby universes', causing it to expand, new theoretical study suggestsThe universe is expanding faster and faster, but not all scientists agree that dark energy is the cause. Perhaps, instead, our universe keeps colliding with and absorbing smaller 'baby universes,' a new theoretical study suggests.

Dark matter could be gently wobbling space-time around us — and scientists may finally know how to detect itA new paper suggests we may finally be able to uncover the identity of dark matter using the same technology that detects ripples in space-time known as gravitational waves.

Physicists want to use gravitational waves to 'see' the beginning of timeGravitational waves are ripples in the fabric of space. Waves that originated in the early universe could carry important information about the phenomena that occurred there.
