From the Big Bang to the possibility of alien life and deep space travel, scientists expand our understanding of the universe.

Ever wondered what would happen if you were sucked into a black hole? Or, if wormholes could make time travel a reality? And could life on Earth survive a huge meteor strike like the one that took out the dinosaurs?

This series combines the most current scientific information, cutting-edge computer graphics, dramatic time-lapse sequences and everyday examples to shed light on some of the most mind-boggling aspects of our universe.

Sizing Up The Universe
In the known universe, size matters. From the enormity of the galaxy, to the tiny atoms that are the building blocks of everything, the universe is a place of extreme sizes. From the unimaginably big to the incomprehensibly small, explore size in the universe and exactly what it means to us and our understanding of the cosmos.

Blowing Up The Universe
Hidden behind all its serene beauty, the universe is a place of lurking peril, full of powers so immense they defy our comprehension. Take a look at the universe's dark side, a cosmos of impending menace. From earthquakes to hurricanes to massive asteroid impacts and exploding stars, explore its explosive powers and uncover the destructive forces that could be unleashed at any moment.

Speeding Through The Universe
In the cosmos’ vast expanse, nothing matters more than speed. Whether venturing out to the farthest reaches of the solar system or exploring the mysteries of space and time, speed is the key. From the merely quick to the unimaginably fast, explore speed and find out how tremendous velocities reveal a universe stranger and more exotic than ever imagined.
