Space seems like it goes on forever - but does it? Surprising new evidence suggests that not only is there a place where the universe ends - but there is something unimaginable lurking beyond it.
Time is not what we think it is. New research questions the nature of time and challenges our most basic perceptions about reality.
New evidence forces us to consider a truly shocking possibility - is our reality an illusion?
New research is discovering that thoughts can fly across space and that we all may be part of a global consciousness. Scientifically, a sixth sense is entirely possible.
There could be more than one version of reality - and more than one you. As scientists unravel this possibility, a new astounding one emerges: these parallel worlds could determine the destiny of the entire universe.
A revolution in science is underway that will transform life on Earth and ensure our survival as a species. If we can solve the equation of everything, it will present the keys to creation itself.
Physicists are designing warp drives, learning how to pry open wormholes, and finding cracks in the fabric of the cosmos to bring the final frontier within our grasp.
Death is a humbling reality - but what if life had no end? Cutting-edge science embarks on a bold mission to extend human life and may soon bring immortality within our grasp.
Across the galaxy lie exotic worlds made entirely of water or stewing with poisonous gas. What kinds of creatures thrive in these places? Would they resemble beings on Earth, or could life take on new and unexpected forms?
As before, these and other topics (including contemplations of eternal life, what aliens look like, and the possibility that there are more than three dimensions) involve some very complex scientific experiments and dizzying mathematics. But there's also a healthy dose of whimsy (one scientist uses the video game Asteroids and a bagel to illustrate her theories) and plenty of graphics, models, and outstanding visual effects, plus amusing cartoon animation and Freeman's personal touch via several reenactments of his own childhood experiences. All in all, this beautifully produced series is at once provocative, edifying, and entertaining. --Sam Graham
