We take a look dark matter and dark energy, why some scientists still believe they exist, where the theories came from, and how they affect the universe.

We spend some time looking at time, how we have measured it’s passage throughout history, philosophically, how it’s affected by gravity, and the very concept of time itself. Plus find out why Einstein proposes that we travel through Time at the speed of light, how Atomic clocks work, and is it possible gravitational fields warp time?

We look at the results from Gravity Probe B and how they relate to Einstein’s predictions on mass, space, time and how they all interact with one another.
