“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 ...

What does it mean to be to space-time? The seemingly simple question gets to the essence of twentieth-century physics and has ...

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

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

A new physics paper takes a step toward creating a long-sought "theory of everything" by uniting gravity with the quantum world. However, the new theory remains far from being proven observationally.

According to Newtonian physics, the gravitational attraction between two masses is proportional to the inverse of the square ...

Since that day, LIGO — composed of two highly sensitive laser interferometers located in Hanford, Washington and Livingston, ...

Ten years after LIGO’s historical detection of gravitational waves, the project is cracking black hole mysteries at an ...

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.
