Black Hole Presentation:

We have a power point presentation which you should be able to find in the shared folder by Tuesday.

The presentation is about some of the basics of black holes and gravitational lensing.

Gravitational lensing is the phenomenon in which light's path is skewed due to the gravitational force of a supermassive object. Because light has no mass, it is not convenient to think of the supermassive body as affecting the photons directly, but rather bending the tracks on which they travel, as theorized by Einstein.
