What I said is about the limit of my knowledge unfortunately. However here’s the paper from the University of Sidney that goes into much greater detail. pdf warning https://arxiv.org/pdf/1202.5708v1.pdf From the paper: > These results suggest that any ship using an Alcu- bierre warp drive carrying people would need shielding to protect them from potential dangerously blueshifted particles during the journey, and any people at the des- tination would be gamma ray and high energy particle blasted into oblivion due to the extreme blueshifts for P+ region particles.

I was assuming conventional propulsion at 95% c. An Alcubierre warp field would be ideal, assuming the problems can be overcome: http://en.wikipedia.org/wiki/Alcubierre_drive#Difficulties http://arxiv.org/abs/1001.4960 http://arxiv.org/abs/1202.5708 I'd enjoy seeing your calculation of the number of years that would have passed on Earth for a round-trip of 100 light-years out.

Sorry for the botched formatting (HN is for some reason not showing me a edit link :/ ) A quite interesting paper on the topic is McMonigal & al. [1], it is a bit technical but they discuss the Alcubierre warp drive quite nicely. To elaborate on the second paragraph about special relativity, one way to define Lorentz transformations is, that they are the transformations which preserve the causal structure of Minkowsky space. On the other hand, the speed limit is a direct consequence of the Lorentz transformations. So the causal structure and the speed limit are directly related. To look again…

Here is a paper on the results of interactions with external matter en-route: http://arxiv.org/abs/1202.5708 With a couple of popularizations: http://www.theregister.co.uk/2012/03/04/killer_warp_drive/ http://www.universetoday.com/93882/warp-drives-may-come-with... (Essentially, particles encountered en-route pile up near the boundary and are released in a large burst when you turn the thing off, which is potentially very bad for the local environment, of which you are a part.) And here's a paper on the horizon-like properties of the warp bubble boundary…
