Is time real or is it an illusion?

Light exists outside of time.

  • Time can change depending on how fast you're moving through space. Also, time can "flow" at different rates for different observers.
  • Light doesn't experience time — it exists outside of time.
  • We perceive space and time differently, but they may be woven together. For instance, they both balance each other out: If you are still, time goes by at a natural rate. However, if you move through space very fast, time begins to slow down.

Where the evidence of fake news is really hiding

When it comes to sniffing out whether a source is credible or not, even journalists can sometimes take the wrong approach.

Sponsored by Charles Koch Foundation
  • We all think that we're competent consumers of news media, but the research shows that even journalists struggle with identifying fact from fiction.
  • When judging whether a piece of media is true or not, most of us focus too much on the source itself. Knowledge has a context, and it's important to look at that context when trying to validate a source.
