Seeing as all ideas -especially good ones- are recycled, I wouldn't doubt it at all if the Node Drive was inspired by both of those.


The amalgamization of all the best bits of so many classic sci-fi series is a large part of what makes SotS so great! :thumbsup:

I'd look a little further back into Sci-Fi history than 2000 - 2005 for the inspiration for the node drive. ;)

Not sure about the LHC, but I know the guys in the ALPHA and ATRAP groups have been working at it for some time, but with limited success. To be honest, I'm not even sure how the ALPHA group are collecting their antimatter (me thinks some sort of collider, since antiprotons are... difficult), but I seem to recall that the ATRAP group are collecting their positrons, using a similar method to myself, from decaying sodium-22 - the yield is incredibly low (due to losses in the system), but it is reliable.

ANYWAY, back on topic: the general consensus in the community at this time is that antimatter will act in more or less the same way as matter when it comes to reacting to gravity - but this *is* science, and experimental/observational evidence takes precedence over theory (or rather it should, but the physics world is a mess of political games as we struggle for the ever dwindling funding :( ). Not that I'm saying that I'm for the dark matter/energy/flow/invisible pink unicorn theory (though the latter does have some merit :D ) - I'm actually a proponent of a theory of one of my old lecturers, called process physics. Curiously enough process physics now has 'slipstream' type things as part of the model, and a number of other fun oddities too :thumbsup:.

Anyway, I've made 4 posts in the last 24 hours, and I'm getting dangerously close to loosing my 'lurker' status :P

My personal favorite explanation of Dark Energy is that it's simply an observational bias resulting from insufficiently analyzing the effects of General Relativity in our bubbly universe. GR math is hard, so modern cosmology pretty much just assumes homogeneity on sufficiently large scales. Some people think they have results that show large differences in time rates between voids and matter concentrations (on the order of 30%), which would significantly affect observations.

I've not had the time to go through the math, but qualitatively it is appealing. Some information on it is available here.

Having all of that "invisible" matter/energy located within (or beyond) the Meniscus works, I suppose. It would mean that matter/energy that exists in the Meniscus would still have a tangible effect on observable space-time, which raises some interesting possibilities. I take it that the SotS-verse operates on some variant of membrane thory then? Or does it use something more esoteric, like Heim theory to explain things?

While you are, of course, the author and absolute authority on your own work, I am personally in favor of the idea that their entire universe is actually a complex simulation. :)

Energy and matter which are "dark" in the SotS universe--by which we mean non-detectable by telescopes, but can be inferred by observing gravitational lensing and other visible effects--are easily explained by understanding either the Menisceal Principle or the Vitalist Principle.

As for the universe being a complex simulation? You are certainly correct in the strictly technical sense. :P

I'm sorry, was there an Andromeda reference in the last page? I haven't even thought about Andromeda since the '90s, lol. Good reference.

The Mote in God's Eye perhaps?

The Alderson drive is not, strictly, a faster-than-light drive: it can more nearly be likened to a device able to use a form of wormhole, whose entry and exit 'Alderson points' are at either end of an 'Alderson tramline'. Alderson points are difficult to find. Alderson tramlines form between points of equipotential thermonuclear flux located near stars. Not all star pairs form Alderson tramlines, and not all those tramlines which do form are large enough to take a spaceship. This means that in order to travel between star systems, it is frequently necessary to carry out a series of Alderson jumps interspersed with periods of travel between Alderson points in normal space...

I just want to say, holy shit, your avatar and nickname are freakin awesome Hari Seldon. I am reading the series currently after my... how you say... rediscovery? of Issac Asimov.

Sorry to go off-topic, I just wanted to say that. :D
