Re: SPACE
Well, that depends on needing earthlike planets. If our descendents (ha!) can happily live in zero g habitats, then all you need a star for is heating, and mineral resources. If you can get by without the heating, then you don't need to come further in than the equivalent of the Oort/pluto in the Solar system. There are billions of years left in the universe, if we get into space in reasonable numbers, then somebody, sometime, is going to go travelling.Dio wrote:I don't believe any form of sub-c travel is really feasible for interstellar flight - I mean, even assuming a pretty unlikely 0.1c, we're into transit times measured in thousands of years (using my previous guess of two to three orders of magnitude closer than the nearest star for habitability).
If there are travellers in the Oort, they ought to have noticed us by now, so I suspect there aren't.

Re: SPACE
Youd certainly need heat/energy in some way.
So it would be more a star-hopping probability then planet-hopping.
That said, does Alpha Proxima have a planet?
(don't have Celestia on this pc to check)
So I guess the question is if the "capture" process is more costly then the theoretical energy you can get from it.
It wouldn't do as the primary source of movement, but if your getting to such a speed were the dust becomes a problem, then presumably thats also enough hitting your ship to harvest it without too much effort.
I don't think we can make assumptions that density is uniform or the same stuff yet either. (well, obviously its not uniform over the whole universe, but on the ""small"" scale). I think humanity would need probably a few millenniums of stela travel before and probes before we get anything inter-stela.

Well, it needs to be captured and converted to energy.Well, you can pretty easily work out if that's feasible or not now (assuming our figures for the density are right).

Neat idea, but does indeed seem implausible.Well, I don't really believe in it myself, generating the magnetic fields may be forever beyond practicality, but:

Arianespace postpones the Ariane 5 launch with Skynet 5C and Turksat 3A
Tonight's heavy-lift mission with Skynet 5C and Turksat 3A has been postponed after a software test with the Ariane 5 ECA launch vehicle showed a non-nominal result.
The decision was taken by Arianespace to ensure a thorough validation before it approves the launch.
Both the Ariane 5 and its Skynet 5C and Turksat 3A payloads are in a safe condition.
Arianespace will announce the new mission date as soon as possible.

Just under 38 minutes to go.
