To add to the thought of James Thirteen concerning XM
To add to the thought of James Thirteen concerning XM Making a wormhole just got easier... ...but it's no simple matter. A bit of 'exotic matter' and you could be going anywhere. Good news for time travellers - it just got cheaper. The amount material needed to build a window through time is infinitesimally small, new research shows. To travel through time, all you need to do is open a wormhole in space-time and step through it. And to do that you need a magic ingredient called 'exotic matter', which is repelled rather than attracted by gravity. The hitch is that no one has the remotest idea how to make exotic matter. But don't despair, say Matt Visser, of the Victoria University of Wellington in New Zealand, and his colleagues. They have shown that when we do figure out how to make the stuff, we won't need very much of it. As Star Trek: Deep Space 9, Quantum Leap and Stargate have taught us, wormholes are the preferred mode of transport for today...
