Is Space Time Travel Possible?

Scroll down to explore a learning path based on this topic.
Playlist Description

We've seen time travel in our favorite movies, but is it possible in real life? Imagine being Alice after she fell through the rabbit hole, swirling past ticking clocks as time melted away on her way to Wonderland. Now, replace the rabbit hole with a wormhole and Wonderland with a different time, and you're beginning to understand the theory of time travel through space. In the 1930s, Albert Einstein and Nathan Rosen suggested that wormholes, which are defined as pathways between dimensions and alternate universes, exist throughout space and can be possible portals to other worlds. And although these wormholes are so microscopically small, they still may have the power to affect our universe and others in major ways.

However, not all great minds agree. Scientist Stephen Hawking has offered different perspectives over the years, first contending the concept was impossible, yet more recently outlining several philosophies including that of a fourth dimension. But what is the actual probability of stumbling into time travel? Will we ever fully know the extent of our universe? Explore this playlist and be inspired to decide for yourself.

Complete video at: http://fora.tv/2009/03/19/Ian_Morison_Its_About_Time Ian Morison, a professor of astronomy, examines the complex possibility of using a wormhole to travel through space and time. ----- Professor Ian Morison discusses time, one of the most mysterious concepts in our Universe. It is easy to describe how we define its passage and how we can make exceedingly accurate clocks but questions as to what determines the arrow of time and whether time travel is possible can tax the most brilliant minds! - Gresham College Ian Morison made his first telescope at the age of 12 with lenses given to him by his optician. Having studied Physics, Maths and Astronomy at Oxford he became a radio astronomer at the Jodrell Bank Observatory and teaches Astronomy and Cosmology at the University of Manchester. Over 25 years he has also taught Observational Astronomy to many hundreds of adult students in the North West of England. An active amateur optical astronomer, he is a council member and past president of the Society for Popular Astronomy in the United Kingdom. At Jodrell Bank he was a designer of the 217 KM MERLIN array and has coordinated the Project Phoenix SETI Observations using the Lovell Radio Telescope. He contributes astronomy articles and reviews for New Scientist and Astronomy Now, and produces a monthly sky guide on the Observatory's website.
