When getting water at a segregated fountain, young Morgan begins to reflect on the subject of race. Is one really superior?

Researcher Josh Correll explains what led him to focus on rascism, and ithe importance of understanding it.

An experiement shows when one person in a group starts to “take” instead of “give,” gradually most of the group will resort to taking for themselves as well. Are we influenced by our surroundings?

Stereotypes affect everyones behavior; Josh Correll illustrates how little snippets of information can lead us to our behavior.

No matter how arbitrarily a group is formed, we automatically find ourselves aligned with that group, putting it's needs before our own.

Researchers have found that the feeling of joy at our rival's failure is something that our brains learn to crave.

Morgan reflects on his youth, facing a stereotype and standing up to a bully.

Do we need a time machine to time travel, or could a wormhole do the job?

Professor Paul Davies uses a chocolate factory production line to illustrate how the future limits what can be in the present.

Some theorize we each have an individual slice of the present and our brains trick us into believing it is the same for all. Does our brain trick us into only seeing time in one direction, and could we change that view?

Closed time like curves, exotic arrangements of matter overlapping back upon themselves, suggest it might be possible to go back in time. Professor Todd Brun studies this theory, but believes we cannot change events.

Experiments with subatomic particles show the future position of the particle limits where it can be in the present. Professor Paul Davies thinks may also be happening at the level of our everyday reality.

Morgan wishes his grandmother was still alive, which leads him to ponder the concept of time.

As young Morgan plays in the woods in summer, he wonders if time really exists

Richard Lenski, who is conducting the world’s longest evolutionary experiment has tended colonies of e-coli over 27 years. After years, one strain mutates. Why did that group evolve?
