Hi. Here's Stephen Colbert (out of character) and astrophysicist Neil deGrasse Tyson having an 85 minute conversation about science, physics, and the universe.

What does a Higgsless universe mean for science? The Higgs Boson is quite important to the standard model of physics. If it exists, it plays a major role in explaining how particles acquire mass. There’s a distinct possibility that the Higgs Boson may not even exist. Stephen Hawking made a famous bet that the Large Hadron Collider (LHC) wouldn't find it. So far both the LHC and Tevatron, another massive particle accelerators have both searched much of the energy ranges we expected to find the Higgs with no luck. So, then, what does it mean if we don’t find the Higgs at all?

An Interactive Space Simulator "Smash planets together, introduce rogue stars, and build new worlds from spinning discs of debris. Fire a moon into a planet or destroy everything you've created with a super massive black hole. You can simulate and interact with our solar system: the 8 planets,160+ moons, and hundereds of asteroids, the nearest 1000 stars to our Sun, and our local group of galaxies."

If the universe is a hologram and the healthy human brain a valve of consciousness then where'd this mental infinity come from? Are we simply living the simulacrum? Or does Pi protect us all, forever, infinitely?
