  1. Any large scale modified gravity ( TeVeS is a re-worked MOND ) has mostly been put to rest by the recent Gravitational wave detections. GR is a geometric model, and as such, can only be quantized by quantizing space-time, as LQG attempts. That doesn't mean that a return to a field model will forever resist quantization, or that an entirely new approach, such as M-theory won't yield the desired results. The only requirement is that each model reduces to the others ( gives equivalent results ) at the appropriate boundaries.
  2. Idea for jet engines, who to contact?

    Here, have a look at this discussion... https://aviation.stackexchange.com/questions/31613/why-are-contra-rotating-jet-engines-so-rare
  3. Fox News Watch

    Why watch it if it upsets you. As Ten oz has suggested, there are many other sources of less biased news ( none are unbiased ).
  4. So who's going to win the world cup?

    The hard-working ( and lucky ) Icelanders came up against a team that works even harder, and are leaving the tournament. Nigeria looks set to go through, as I don't think Argentina can pull off a decisive win. England ( my favorite as Italy didn't qualify ) shouldn't have a problem with Panama ( but you never know ). The first test of their mettle will come against Belgium.
  5. Amazon - Threat or Thrive?

    Call me old fashioned but, although I have ordered things from Amazon ( mostly the British, French, Russian and American Secret bombers/fighter Projects book series ), ALIExpress and eBay ( mostly watches for my collection ), I prefer to 'feel' the heft of things I am about to lay down hard-earned cash for.
  6. The world would be a boring place if everyone thought the same.
  7. what is quantum theory?

    Quantum theory is a paradigm ( the foundation of how we think about things ) shift in the way we view reality. At very small scales, classical physics ceases to make sense, and the only way we can force it to make sense, and agree with observation, is by treating events as probability distributions. I get the impression you're young student. Anything we tell you will presently sound like gibberish. But if you stay interested eventually you'll learn the math to make sense of it, and one day, far in your future, and probably long after you've forgotten the math, you'll say "Ah-Ha, now it all makes sense. ( Oh wait, that's me )
  8. Energy is also a property and information. So are the winning lottery numbers. And if you know them before they're actually drawn, you are breaking causality. ( time travel also implies causality breaks, But GR, being strictly classical, does not forbid it )
  9. Idea for jet engines, who to contact?

    And how would you ensure that, since the rotation of the gas flow through the compressor changes with different compressor speed and output power ? You can't have variable pitch fan blades, so your only option is to ensure straight flow at all times.
  10. Information is any property of a system, say momentum, for example. If I can transfer the momentum of photons to a solar sail faster than the photons can get to the sail, then it will move without cause, so breaking causality. Is that simple enough ?
  11. Idea for jet engines, who to contact?

    Agreed on the gyroscopic effects ( only valid for a hovering aircraft ), but the attitude of the gas flow entering the next stage has to be straight, otherwise the compressor blades lose effectiveness. Most older, straight turbojets use variable pitch guide vanes/stators on the first few compressor stages ( see GE J-85 and J-79 ). Low pressure fans on turbofan engines are driven by a separate shaft/spool such that most engines are two shaft/spool designs. Only RR has ever gone to three shaft/spool designs, and they've mostly given up on more than two. Last engines to use tree shafts/spools were the 70s vintage RB 199 ( multinational ) and RB 211 ( commercial ). Complexity ( and part count ) also grow with number of bearings since at least two are needed for each shaft. Specific fuel consumption and thrust are more important than part count these days. The most advanced military engines employ variable cycle/ bypass to optimize thrust/SFC at all speeds to supersonic, while the most advanced civil engines use geared fans to optimize the same at typical ( subsonic ) cruise.
  12. Did Trump get anything right?

    Of course he's done something good for the country. He quit show business, didn't he ? ( he's taken his act on the road, and is now firing people in government about as often as he did on that stupid show )
  13. The North Korea Problem

    Damn straight, iNow. We'll conquer the US and burn the white House down again ( ? ).
  14. The North Korea Problem

    G W Bush axis of evil... Iraq, Iran and North Korea. D trump axis of evil... Canada, Mexico and most of Europe.
  15. So who's going to win the world cup?

    Brazil has failed to impress during the last decade, they may be losing their magic. Germany has lost some key players, don't know if the youngsters can pull it off. Spain is starting to wind down, amazing play still, but have lost some very important games. Both Italy and Holland failed to qualify, while Argentina barely slipped in. I would say France is the odds on favorite, but I'm hoping for an English miracle. Haven't worn my St George's cross jersey in a while
