Another Wacky "Theory"

Particle physicist Dr. Brian Cox believes that the answer to the meaning of the universe lies in gravity. In this BBC Horizon film "What on Earth is Wrong With Gravity?" Cox goes on a road trip across the USA where he fires lasers at the moon in Texas and goes wild in the desert in Arizona. He encounters the bending of space and time at a maximum security military base and tries to detect ripples in our reality in the swamps of Louisiana.
