Not sure how that rebounds on causality. Duane Imagine you had a bazooka that could fire warp missles that used the heim FTL drive in question. Whether the missles experience time dilation effects themselves is moot. Now read this site: http://sheol.org/throopw/tachyon-pistols.html Replace the term...

[quote=ravingdave]Don't get me wrong, I think prisons are not a good solution to the problem. I don't favor prisons. The idea that you are going to fix anyone by boring them to death for months or years is just silly. I've been thinking for years that some sort of mandatory educational boot-camp lik...

Edit: You can still have wormholes, assuming they can't be used as time machines.

I'm not qualified to comment on whether Ray K is right or not. He's extremely intelligent, but that doesn't mean he's right. But if he is right about it being feasible, then I'm having trouble accepting that 'the masses' will allow the singularity to happen as he imagines it. If almost half the coun...

bussard thought gain was = to 40 in 1993?
I'm here at work killing time and I felt like reading some articles off askmar. I just noticed something from the article "The QED Engine: Fusion-Electric Propulsion for Cis-Oort/Quasi-Interstellar Flight", written back in 1993. On page 5, he writes: "Typically, the DCS system here will convert abou...

Re: Be swift!
Sorry for the double post but... I just thought back to the original Google video where bussard does his rough estimate based on something like a 2% royalty fee, whomever owns the patents, well once they get the Gigawat polywells they can actually start making money on royalties by getting the polyw...

http://www.orionsarm.com/ It's a collaborative sci-fi worldbuilding project. Takes a lot of ideas from kurzweil (though over a larger timeframe), an idea of multiple singularities (defined as discrete levels of ai intelligence), and it expands nanotechnology into pico and femtotechnology. No FTL, ex...

Yeah I remember that movie. And whatever was in the forcefield bubble wouldn't feel inertia as the bubble accelerated into space =) As for the crop circles, I don't think "the aliens" are trying to tell us something. The hoaxers that make crop circles use ropes and wooden boards as they spiral outwa...

Well, assuming someone does develop it (China, Nasa, ?), how cheap could we guess that a mass produced ARC QED might be? Could it someday be comparable to the cost of large turbofan engines on commercial airliners? Or is the complexity high enough that these engines will only be used on military or ...

QED could get you to Mars in 3 weeks. IIRC Mars in 35 days, Saturn in 76 days That's more a design issue. If you want to make it in 3 weeks rather than 35 days, you simply have to increase the mass fraction of your spacecraft. IIRC, when bussard wrote about his concepts, the mass fractions of the s...

Hahaha Mike, I appreciate your comment because I'm normally the one that says what you just said, and I realise I may have mistyped. I'd have to look at the evidence first and see the critiques of others, because I could be skeptical of some of the reviewers. I wouldn't blindy say that it has to wor...
