And here I thought people would go for a galaxy gun instead.

I don't remember anyone posting this in this thread, apologies if they did. It may point towards some oddity of gravity and inertia which may be the Woodward-Mach effect or whatever signal Woodward's experiments are detecting (assuming it's not noise): http://www.technologyreview.com/view/506681/fly...

Note: Of course if you were just observing a M-E thruster accelerate without ejecting any propellant it would appear to reach the point where it would go over-unity, because you wouldn't know what it was pushing against. There would be no conservation of momentum. I ask about an alternative mathemat...

Ok, well, I'll ignore secondhand accounts about what some of the physicists say about having to do Lorentz transforms and try to engage with this mathematical model for one or two posts. It only becomes an 'un-physical' violation if there is no propellant to counterbalance the Q.V.m.Δt term. This of...

The Wikipedia article does indeed seem to have the necessary basic forms of the Lorentz transformations for you to plug numbers into: http://en.wikipedia.org/wiki/Lorentz_transformation The first few paragraphs are mostly history lessons, then most of the rest of the article is the various forms of ...

Amongst other places, GoatGuy's math appears here: http://nextbigfuture.com/2011/02/nasa-flight-forum-discussion-of-mach.html Imagine for the moment that two equations of MachEffect vehicles are true: A = ΔV = KME × PELECTRIC / M V = KME × PELECTRIC × T / M EKINETIC = ½MV² EKINETIC = ½M × ( KME × PE...

chris, engineers are taught from day one, just as I was in high school and college in the lower level courses in physics I've taken; that one needs to be especially careful with non-inertial frames of reference. All thrusters put out constant stationary thrust. That thrust is not constant or invari...

It is simple to disprove that last statement - merely show the forum a mathematical calculation ending in over-unity energy gain, and it will either disprove the last statement, or will have an error in it. The problem is when the inertial frame of reference is changed. If that is done then immedia...

Once I got to the point in the evening where I had a bit of spare time and could try to play around with the math a bit, it struck me once again how this topic causes people, myself included, to not see the forest for the trees. Ok, as we established a while back and you just repeated - acceleration...

It is a case of doing the math wrong. If you imagine a rocket thruster on a rotating swing arm, such as in the Roton design; and feed it fuel through the arm, doing the math the way GoatGuy and Andrew Palfreyman recommend generates the same absurd result. Obviously it is method that is at fault. Ji...

Also, I didn't notice if anyone had posted this in the last few days of squabbling: NBF appears to have an early review of Woodward's book. http://nextbigfuture.com/2013/01/reviewing-woodward-book-making.html Appears that John Cramer wrote the foreword, and his comments include: "Many of the theoret...

Entropy, expansion and the heat death of the universe... The outline of the approach popular since the late 1990s has seemed to me to be the following: the universe starts out as a concentrated point of very dense, hot matter in an explosion. As it expands, matter burns down to less energy-intensive...

And yes. For ME to "work" the energy must come from somewhere. Does that "coming from somewhere" increase or decrease the order elsewhere? i.e. is it thermodynamic or quantum? My impression from what I've seen of Woodward's work is that it's thermodynamic. There should be a straight-up transfer of ...
