    A Century Later, General Relativity Is Still Making Waves

    Einstein's general theory of relativity was proposed a century ago and has been confirmed in many ways. The existence of gravitational waves was the last major unverified prediction of general relativity, until now.

    The Marvel of Gravitational Lensing

    Gravitational lensing takes the common ideas of a glass lens and transforms them to cosmic proportions.

    A Black Hole Visits Baltimore

    What happens when a massive distortion in space-time comes to Baltimore's Inner Harbor for a crab feast? OK, we haven't got that crab part, but we can show you the visual distortions due to gravitational lensing.

    Einstein's Crazy Idea

    Einstein's general relativity uses the strange notion of curved space to reinterpret gravity, and explains things that Newton's version of gravity can't.

    The Naming of Comets

    In a playful explanantion of the ways comets are named, I've adapted T. S. Eliot's poem "The Naming of Cats" for my own celestial purposes.
