Testing for a Holographic Universe

Is our universe simply a hologram? Particle astrophysicist Craig Hogan is building the most precise clock of all time to directly measure whether our reality is an illusion.

"In 2008, Fermilab particle astrophysicist Craig Hogan made waves with a mind-boggling proposition: The 3D universe in which we appear to live is no more than a hologram. Now he is building the most precise clock of all time to directly measure whether our reality is an illusion. The idea that spacetime may not be entirely smooth—like a digital image that becomes increasingly pixelated as you zoom in—had been previously proposed by Stephen Hawking and others. Possible evidence for this model appeared last year in the unaccountable 'noise' plaguing the GEO600 experiment in Germany, which searches for gravitational waves from black holes."

  • America's two political tribes have consolidated into 'red' and 'blue' nations, with seemingly irreconcilable differences.
  • Perhaps the best way to stop the infighting is to go for a divorce and give the two nations a country each
  • Based on the UN's partition plan for Israel/Palestine, this proposal provides territorial contiguity and sea access to both 'red' and 'blue' America

Ideology drives us apart. Neuroscience can bring us back together.

A guide to making difficult conversations possible—and peaceful—in an increasingly polarized nation.

  • How can we reach out to people on the other side of the divide? Get to know the other person as a human being before you get to know them as a set of tribal political beliefs, says Sarah Ruger. Don't launch straight into the difficult topics—connect on a more basic level first.
  • To bond, use icebreakers backed by neuroscience and psychology: Share a meal, watch some comedy, see awe-inspiring art, go on a tough hike together—sharing tribulation helps break down some of the mental barriers we have between us. Then, get down to talking, putting your humanity before your ideology.
