Brief post today, but I wanted to share it anyway. Researchers at the University of Florida in Gainesville have located an extremely beautiful and distant example of gravitational lensing. This is important to me because U of F is local to us.
Gravitational lensing occurs when light passes through an extremely powerful gravitational field, becoming bent. This is a lot like how refractive materials, such as glass, can bend a light ray. Of course photons are massless, so gravity shouldn't affect them. Gravity obviously do
