Please join us for the inaugural event of the new Ohio State Astronomy and Astrophysics (OSAA) public lecture series! David H. Weinberg, the Henry L. Cox Professor and Chair, Department of Astronomy will describe three startling, recent discoveries related to the laws of gravity: 

Unusual alignments in objects moving in the distant solar system suggest a previously unknown planet — 10 times more massive than Earth — orbiting far beyond Neptune and Pluto. 

Physicists detected ghostly ripples of space-time, produced by black holes spiraling in a galaxy more than a billion light years away—directly confirming two of Einstein's remarkable predictions about General Relativity.

Observing still more distant objects, we see the universe’s expansion is NOT slowing down, BUT speeding up, signaling a mysterious "dark energy."
