    • Big gun? Workable, but you can't send anything fragile, including people

    Aha, that's simply because your gun isn't big enough. Consider an 11km high pylon tower, quite doable, with maglev tunnels in them to accelerate a vessel at 7g, quite acceptable again. The savings you make in fuel consumption and atmospheric density/turbulence are quite significant enough to lower the cost of launches to LEO to justify the initial expenditure, assuming you had a long term path to profitability in mind, like siting medical facilities in orbit for the rapid drop of transplant organs or something.

    There simply is no tech out there which can come close to the reliability, efficiency, and costs of horses. that is why everyone is using them.

    Forgive the adjustment of your comment, but it does serve to underline the point - rockets carry all of their fuel with them. There's no reason why we can't build a gantry several kilometers high which supplies energy to ships to help attain higher speeds as they launch. So for one they start higher, and for another they start faster. Maybe that will only be a significant factor in getting to LEO, but from LEO you can go much farther a lot easier. Make the trip to LEO easier, and the whole thing becomes a lot simpler and cheaper. Like a staging post.

    A relativistic bomb is where you accelerate something to a fraction of the speed of light and slam it into a planet. Something the size of the Space Shuttle at 20% light speed would be more powerful than every nuke on the planet combined. A 1km diameter asteroid at 90% the speed of light would atomise everything on the surface of the earth and reduce it to a vast sandy wasteland with patches of glass where it had fused in the heat. The top 10m of the seas would boil off too.

    The general understanding I have of these is that relativistic bombs could never work, since they would be torn to shreds by the interplanetary medium long before they hit the target. At the very best, they would be impossible to steer accurately for similar reasons.

    No I really don't see the difference between those two things besides ideology. You've chosen to argue that one is more likely than the other without any evidence whatsoever. The two things are equally possible.

    See, this is what I mean about knee jerk reactions without ever engaging higher cognitive functions. Intelligence is the mother of all evolutionary advantages, do you really think it that unlikely that we might be the first to develop it?

    *boggle* I challenge you to find one discovery in the history of the human race that wasn't built on the backs of previous researchers and the observational evidence that came before.

    There's even a word for it, serendipity. Anyway I think you misunderstood my point, its not that people out for a wander stumble on new discoveries out of the blue, although they have, its that imagination and the ability to step outside the box mentally play an important role in the scientific method. Strident dogmatism is the antithesis of that, and will ultimately lead to serious problems.

    We don't really. We have a tiny percentage of some species that happened to be in the right place at the right time, which would itself be only a tiny percentage of all species which ever existed. Funerary rites would most certainly interfere with fossilisation, and if you wouldn't even want to credit them with that, you can at least envision that they would have an orderly process to dispose of the remains of their dead and not just leave them where they drop.

    I think I do. I'm not sure that you are following the scope of the disappearing act that you postulate, again, on no evidence whatsoever.

    No, I think you don't.

    The number of extinctions changes what in my argument?

    The underlying assumption that we know all there is to know about everything? Bottom line is, we know very little about anything.

    Here, let me make one last attempt to garner your understanding: Moses was an alien. Can you disprove it? After all, an alien capable of making the trip would also be capable of perfect deception. I could spend the next year giving you ad hoc reasoning as to why your objections don't mean anything. But I just pulled it out of my ass. It's a completely unfounded assertion. But I could defend it in exactly the same way you are defending your statements. The point is that without a shred of empirical evidence to base your claim on, you, too, are just talking out of your ass. And that, not some dogmatism, is what makes it nothing more than an amusing story.

    And we're off. The extreme example I used was intended to prove a point about the use of imagination in the scientific method and the way that the dogmatic herd thinking which is becoming prevalent runs the risk of damaging creativity in science. I often find this in engineers particularly who are labouring under the mistaken belief that they are scientists. Rigid and conservative thinking is a benefit in engineering, in science it is a detriment.

    The scorn which is being heaped upon even admitting the possibility that such a killing evolutionary advantage as intelligence might have previously appeared before mankind is evidence of a problem. I don't expect you to solve the problem, just pointing out that it exists.

    It's an extreme example as I mentioned, to emphasise the point. The fact is that the scientific method requires both imagination and creativity, and we won't get that while people are jumping with both feet on anything that doesn't fit their assumed orthodoxy. I say assumed because actual scientists know well enough how discovery works, more often because someone said, "hmm, that's weird", than someone said "yes, my calculations were correct".

    Someone who was reasonably familiar with the scientific method would see that you've made no verifiable predictions, that your hypothesis that something 'used to exist but no evidence can possibly be found' is not falsifiable, and conclude that this is fundamentally not a question that can be addressed by the scientific method. If you were to assert that this hypothesis was scientific, you would deserve criticism.

    On the contrary, it is possible that evidence might one day be found to support this. Not very likely, but possible. You have missed the point I was trying to make however - science is not composed of calls to previous authority, they tried that in the middle ages and it didn't work out. This semi-legalistic adherence to methods that many people really don't understand runs the risk of drowning out true creative genius in a flood of self righteous calls to authority from these same poorly informed zealots.

    So, you are now relying on imagined funeral rites to explain the lack of skeletal evidence from a civilization of which you have no other evidence either?

    I'm relying on the idea that such a group probably wouldn't dump their dead into tar pits as a general rule.

    So, you wouldn't recognize carved stone? Or metal? No one in your hypothetical civilization cut a gem, or built a massive city? No subways? No basements? No plastics? No analogues to Cheyenne Mountain? We can somehow find stone tools from millions of years ago, but a whole advanced civilization somehow evaporated?

    That's exactly right, you wouldn't recognise carved stone after its been ground to rubble under tens of millions of years of geology. I don't think you really understand what happens over geological time scales.

    So, let me follow your logic. We have some extinctions which are clearly due to outside events. We have some that are not yet understood. We are causing one ourselves right now. Therefore, it's plausible that an advanced civilization of which there isn't the slightest shred of evidence can be plugged in as a cause.

    I think you might be underestimating the amount of extinction events there actually were. Here are more than twenty that we know of... http://en.wikipedia.org/wiki/Extinction_event

    No, it wouldn't. Biological matter can survive millions of years, let alone all of the artificial materials that such a civilization would have generated. And where in the world's history did this global civilization appear, without leaving anything behind or making a measurable impact on the environment of their time? How is it that we can find trilobites, ammonites, worm impressions, dinosaur skeletons and even the impressions of feathers dating back millions of years, but not one scrap of evidence of an advanced civilization?

    Ask yourself this - how much of the biodiversity of the ancient world have we actually recovered in the fossil record? One percent? One percent of one percent? It takes a pretty specialised set of conditions to create fossils, and it would suprise me not at all to find that funerary rites are not conducive to those. As for the rest, what materials do you imagine would survive? Anything from say ten million years in the past would be indistinguishable from the surrounding strata. And a measureable impact - there were many extinction events of various levels in the history of the earth, and by no means are all or even the majority of them satisfactorarily explained. I would add to that the note that we are right now in the midst of a massive reduction in biodiversity due to our own advanced civilisation.

    The rejection of wild stories which do not match up with any known evidence is not evidence of "mental orthodoxy." It's evidence of a healthy regard for proof. Conjecture about ancient civilizations all you like. No one will stop you. But don't expect anyone to actually take you seriously until you pony of data.
