Any transfer of energy may be assumed somewhat inefficient. For example, suppose that two falling beams hit each other, just right, and one receives a energy transfer enough to create the 11 m/s vector force. The impact likely created considerable heat, and perhaps the 2nd beam moved in some direction also. Therefore, perhaps the total energy transferred was 250 joules, and the part of interest to us is 192 joules.
Amazing how something so statistically improbable happened so many times that day isn't it?
I'm good with your alleging "statistically improbable" as long as you show the statistics that show it's statistically improbable, but in the absence of that, forget it. You don't get to use big words and assert they are Truey. You are not the arbitrator of what happened on that day. You are just one guy arguing that explosives were required without any evidence and without producing serious arguments for that premise.
It's pretty laughable to say something like "it's obvious that it's statistically improbable." What is the chance that of 30 people in a room 2 have the same birthday? If you are gambling, heads you win tails I win, start gambling with 1$ and double it every bet, you'll win it all after a while, right?
Huge fortunes and entire cities, such as Las Vegas, exist because of peoples' poor comprehension of statistical principles.
