If you are planning on doing some interplanetary space travel, this little calculator is what you need. It will tell you how much time you need to set aside for your trip, and how much time you’ll gain by using a faster ship. Only available in Swedish (because NASA aren’t planning any such trips in the near future, so I put my faith in ESA).
Download the tool from here (requires Windows XP SP3 or later).

String theory (and all other theories involving hidden dimensions)
predict that gravity and electromagnetism unify in hidden
dimensions and that the hidden dimensions are indetectible because of
their small size. It does also predict that sufficiently short-waved
photons, with wavelengths shorter than the size of the hidden
dimensions, can enter them. Producing ultra-short photons can thus
manipulate gravity, with revolutionizing space travel applications such
as cheap anti-gravity launches. The
problem that it would require high energy can be practically solved by
concentrating several laser beams on a nanoparticle, heating it to
locally extreme temperatures. An Alcubierre metric can be created by
ejecting multiple nanoparticles from the craft and then beam perfectly
timed laser beams on them (fire at the most distant first so that they are
hit simultaneously), so each nanoparticle contributes a slower than
light effect but together add up to faster than light, creating no discrete
event horizon and thus no Hawking radiation.
