Space and time are intimately linked. Albert Einstein published his famous Theory of General Relativity in 1916, and since then it has become key to our understanding about how our universe works.
Nearly a century after the idea of spacetime was first formulated, scientists have been able to explain black holes, wormholes, the curvature of spacetime and time dilation.
How can space be warped by humans traveling the vast distances between the planets and stars? Can time be stretched and skewed so we can go into the future and the past? Science fiction talks about time travel and faster-then-light-speed propulsion as if it is already a reality, but what does science think? Check out this warped Wide Angle to find out.
- News: Warp Drive Engine Could Suck Earth Into Black Hole
Star Trek makes faster-than-light travel look easy, but could the reality behind warp speed be more destructive? According to Italian physicists, starting up your warp drive could produce a black hole...
- Interview: Dark Energy and Surfing Spacetime
The Starship Enterprise uses it to jump from star to star, but is warp speed physically possible? Yes, says warp drive propulsion expert Dr. Richard Obousy, so long as we understand "dark energy" first.

- HowStuffWorks: How Warp Speed Works
Warp speed is obviously a very useful mode of spaceship propulsion if you're writing the plot of the next "Star Trek" movie -- after all, you don't want the plot to span decades while waiting for Kirk and co. to travel from star to star.

Interview: Antimatter Might Power Future Spaceships
Spacecraft powered by antimatter aren't just for Star Trek -- they're theoretically possible. We chat with antimatter expert George Schmidt.
- News: Warp Drive Engine Would Travel Faster Than Light
Two Baylor University physicists (including Richard Obousy) have outlined how a faster-than-light engine, or warp drive, could be created that would bend but not break the laws of physics.
