Researchers say they may have achieved Einstein's vision of a "unified field theory" that can unite two of nature's ...

In the vast universe, galaxies rotate in ways that don’t make sense if only visible matter is considered. For almost a ...

But a strong gravitational field throws classical predictions off. Einstein postulated three ways this theory could be proved. One was by observing the stars during a total solar eclipse.

The quantum and gravitational theory group works on a wide range of topics in theoretical physics, from string theory to quantum information, condensed matter, and cosmology. Professor Albion Lawrence ...

That theory states that the universe ... will observe tiny fluctuations in Earth’s gravitational field by measuring the distance between two independently flying spacecraft, just as LISA ...

The quantum and gravitational theory group of the Brandeis Physics Department conducts research on a range of topics in theoretical physics, including string theory, classical and quantum gravity, ...
