Re: [Vo]:Interstellar travel
Hi, At half the speed of light, the kinetic energy of a Hydrogen molecule is in excess of 200 MeV. At that energy it isn't going to bounce off. It's going to embed itself in the hull material and deposit all its energy, thereby ablating the hull material, irrespective of its composition. Note also that all this power needs to be supplied by the ship itself, since it's effectively required to overcome the "wind resistance". Even fusing the Hydrogen into Helium in a Bussard ramjet is only going to supply about 13 MeV / H2 molecule, which is far short of the 200 MeV needed. For a Bussard ramjet to break even it couldn't travel faster than c/7. Which implies a 28 year trip to the nearest star beyond the Sun. However complete conversion of matter to energy should do the trick.

First we must overcome The Great Filter. 1) I think I have just finished providing at least one reason why Interstellar travel is limited. 2) I think there is actually lots of evidence of technology beyond our currently acknowledged capabilities (UFO's), though it may not come from the stars.

Re: [Vo]:Interstellar travel
Pity the re-re-make of "Dune" release date has been delayed from December 2020 to October of 2021. We will probably encounter the TOET by then.

Re: [Vo]:Interstellar travel
Ah, yes, the Stoned Ape Hypothesis. I have been studying the Novelty Time Wave Theory of late. Melange is definitely required. :) On Fri, Oct 9, 2020 at 2:23 PM JonesBeene wrote: > Don’t you mean “folded space” ? > > > > That sniff has to do with the spice, IIRC > > > > *From: *Terry Blanton > > Robin wrote: > > The real point I have been trying to make, is that space simply isn't > empty at long distances, so high speeds become > > very difficult. > > > > This is exactly why starships travel in subspace. > > >

Don’t you mean “folded space” ? That sniff has to do with the spice, IIRC From: Terry Blanton Robin wrote: > The real point I have been trying to make, is that space simply isn't empty >at long distances, so high speeds become > very difficult. This is exactly why starships travel in subspace.
