Our Milky Way Galaxy is thought to harbor millions of black holes, the ultra dense remnants of dead stars. But now, in the universe far beyond our galaxy, there's evidence of something far more ominous. A breed of black holes that has reached incomprehensible size and destructive power. Just how large, and violent, and strange can they get?
Episode 7
Tue, Oct 20, 200927 mins
The mind-blowing answer comes from a theory describing the first micro-moments of our universe. Just as scientists began to make precise measurements of the observable universe, new ideas suggest that our visible patch is an impossibly small portion of the whole.
Episode 8
Tue, Nov 10, 200927 mins
How long will the Universe as we know it survive? The answer depends on whether Stephen Hawking's theory about how black holes decay is right. These strange dense objects are like a clock that tick down to a distant moment when all matter and energy will dissipate into the void.

Discussing interstellar travel; how to accomplish it, and why it may be necessary to seek out other worlds like the fictional planet Pandora.
Episode 13
Wed, Jun 9, 201025 mins
Long ago, from the fires of our Sun's birth, twin planets emerged: Venus and Earth. Nature draped one world in the greens and blues of life, while enveloping the other in acid clouds, high heat, and volcanic flows. Why did Venus take such a disastrous turn and Earth developed a vibrant biosphere?
Episode 14
Fri, Sep 10, 201026 mins
What are the energy extremes that define our universe? And how much power can the cosmos wield? Climb a ladder of increasingly powerful events, from frigid gas clouds to nuclear explosions, and travel out to the seething environments of black holes. Find out where Earth fits in the vast power scales of the cosmos.
