    Batman isnt the word for a Bat-like man, (although of course he is somewhat bat-like) he is a unique thing with its own name "Batman". There isnt another Batman and if you created one, he wouldnt be Batman, he'd be something else with another name (Like "Ultimate BAtman" "Batman Alpha" or anything, but there would never be two "Batmen" - well not at the same time at least), because you would always be able to say, "Theres this guy, and theres Batman" and you'd always know which one is Bruce wayne, because he's Batman. And if someone were to liken himself to bats somehow or whatever, or d

    Absolutely Absolutely Absolutely Absolutely Absolutely Absolutely Absolutely Absolutely Absolutely Absolutely Absolutely Absolutely Absolutely Absolutely Absolutely Absolutely Absolutely ***************************************** What if. Predators evolved from facehuggers. Like a bunch of eggs left on a planet for a long time without any suitable hosts. Just look at that face. Also the hunting for sport thing, instinctive. Thats it, thats all I got.
  3. Maybe it's not formal evidence, but if causality violations were happening commonplace, I believe we'd see many more things that didn't make sense. And with so many physicists et al looking pretty closely at so many things, wouldn't it be likely that we'd notice? Which may only relegate causal violations to "rare but possible" like "forbidden" transitions seen in physics (eg: how lasers work) but I think if they were common, we'd see it. Lack of evidence is not evidence of absence, but it is a pretty strong indicator when so much effort is spent on observation. The fact that the
  4. Do we have any handle on how many satellites could be destroyed in this way before we run a strong risk of a runaway Kessler? Closer to 10 or 100 or 1000? Or is it an unknown? Seems to me that specifically targetting and depleting an observation or navigation constellation would be quite difficult, especially if there are spares available for rapid launch. But a random turkey shoot until space is denied to all might be easier to achieve. Makes it a "MAD" arms race between superpowers mirroring the cold war and thus a fairly familiar thing, countries going through the motions.
  5. F117's design was highly limited by computattional techniques and lack of raw processing power. Once computers were good enough, curved, more aerodynamic designs were possible. There are internal structural features (such as the famous "re-entrant triangles") but you won't find an f117 under the skin of a b2 or f35. Stealth capability and radar signiture tracks very well with technological progress, essentially, newer aircraft are better at it. Hence f35 more stealthy than f22. Stealth always a trade-off, f22 or 35 could easily be made more stealthy, but at cost of speed, r
  6. Question: How thick/thin a shell of neutronium would be required to stop 6Gy of radiation?
  7. What exactly is the resolution limit of the average human retina? Like minimum arc length discernible. Assuming sufficient contrast.
  8. I mean, any missile can be detonated on the launchpad for a range of 0m, or rolled down a hill for a range of several tens of metres, but more realistically: There are ways to manage the energy provided by a solid booster, and methods to shut them off before total burn-out have been devised, but as it happens, minimum range of an ICBM is decided largely by structural integrity. Google "depressed trajectory". This is a tactic whereby a submarine would park close to the target and launch its SLBMs on a shallow trajectory, reducing flight time to very low (for ICBMs) values. This a
  9. Reminds me of "Brazil" by Terry Gilliam - a dark, dystopic, high-technology future where the main enemy is...poor adminsitration.
  10. @sevenperforce Oof. No other way to put it. Hang in there bud, we're all rooting for you, whatever happens.
  11. T4 is one of my faves, with the nose up its lines are unlike anything else. And I especially like how the windscreen, with the nose down, looks like it was ripped straight from a Diesel train locomotive. Very Russian.
  12. Went on a skydiving training thing once - didnt end up doing a jump because of weather , but I did learn one thing - skydivers make quite a lot of noise. At one point were were able to watch from the ground as a group did a freefall jump, and we could see them fall from the plane. As they fell, you could hear a quite prominent "tearing" noise that was the noise they made as the moved through the air. Funny the things you think (or that movies make you think) are quiet. Bows, for example (as in bow-and-arrow) make quite a loud noise when shot too - like plucking an enormous guitar str
  13. I had some of those chocolate covered giant ants. They werent very nice. Not in a gross way, just it was like eating a small ball of those shards of popcorn-kernel-skin that get stuck in your teeth, that tasted like soil.
  14. Im not sure exactly, but I imagine it is to do with various gas-dynamic and thermal issues with flushing cryogenic gases through hot metal parts, in variable external pressure conditions, with turbopumps that have just been in some quite horrific conditions. I think engines have to be specifically designed to be re-startable (and even then its not as easy as on/off/on/off). Parts are designed to be used under certain conditions, like temperatures, pressures and mechanical stresses - and a steady-state is much easier to withstand than a variable state. The answer may be as simple as it was not
  15. It's take me a while to type out a full treatment, but here are some hints that helped me understand, maybe it'll unfold something in your head: The key is the values of potential and kinetic energy of the ship(total), the fuel and the exhaust. And that the Oberth effect does not involve any extra energy from any source.
