How Many Black Holes Are In The Solar System?

Dark matter has eluded us for many decades. Even our most advanced particle colliders and sophisticated underground detectors have come up short. But it may be that we can finally solve this mystery with a much simpler experiment, involving a ray of light, a good clock, and the planet Mars.

    Will The Big Bang Happen Again (and Again)?

    S10 E35 - 16m 35s

    How did the universe begin? How can something come from nothing? One way to “solve” this most difficult of philosophical conundrums is to avoid it altogether. Maybe the universe didn’t begin. Maybe the Big Bang was just one in an endless cycle.

    The Final Barrier to (Nearly) Infinite Energy

    S10 E34 - 19m 39s

    One of the final challenges is deciding on the physical vessel to contain our mini artificial stars--and we have some pretty sci-fi options that are nearly ready to go.

    The Crisis in Physics: Why the Higgs Boson Should Not Exist!

    S10 E33 - 16m 36s

    Quantum physics predicts the universe should’ve collapsed right after the Big Bang, because all particles were immeasurably heavier. Yet it obviously didn’t. Observations confirm this puzzle, and experiments at the Large Hadron Collider still haven’t explained why. At its core is the lightness of the Higgs boson, part of the “hierarchy problem,” which many call physics’ biggest unsolved mystery.
