Every time I start on the topic of Energy in School I tell 'em that I will give anyone £10 if they can tell me anything that 'happens' which doesn't involve Energy. I haven't parted with any money yet, although I sometimes have to think a bit hard.
Rotting. Worms crawling around. Bowels emptying. Church bells - need I go on. (Replaces tenner in wallet)
Then it's something (life) NOT happening.Owzat?In any case, when you are alive, life processes are taking place - death means a different set of processes start. If you can detect when the change happens, there must be some transfer of energy.
But the bet also stipulates that something 'happens.' If your square is imaginary, then nothing has 'happened.' If your square physically exists, then forces had to be applied to move it, which involves energy.
I love your sudokus Dr B.I have wasted a lot of energy in that direction!

Every thing that exists, has always existed, nothing new ever comes into existence. (just a quote of my own)
Even The Naked Scientists!?
black holes slowly evaporating as long radio waves into a frigid void over periods unimaginably longer than the 14 billion or so years of time that have happened to date.
That is just not true in fact and probably not true in the way you are thinking about it. It is however true in tems of energy which is conserved. We are so familiar with matter that it is difficult to accept that it is only a relatively short lived feature of our universe. Something that exists in quite large quantities now during the early days of our universe but in the really long term our universe will consist of black holes slowly evaporating as long radio waves into a frigid void over periods unimaginably longer than the 14 billion or so years of time that have happened to date.Energy becomes matter. If a very high energy gamma ray passes close to an atom it is quite possible for the gamma ray to lose energy, the nucleus move a bit and an electron positron pair to be produced out if nothing other than the quantum mechanical vacuum. this is matter being created out if nothing except the energy of the universe. Look up "pair production" to understand a bit more about the process.http://en.wikipedia.org/wiki/Pair_productionEnergy is the fundamental thing in the universe. Even space and time bend and change in response to energy
Fortunately for us, that won't be until 10 to per power of 38 years after big bang.
In the Universe, this should give some really surprising results. With eternity at hand, the vacuum should begin to yield all kinds of objects. Incoherent lumps of random garbage, most of the time. But on very, very rare occasions, you’ll see other objects popping into existence. The Eiffel tower. A purple camel. A golden parking garage filled with chocolate Cadillacs. Napoleon Bonaparte sitting next to Mike Tyson on top of a stack of comic books. As the googols of years pass by, it’s all there.
The last thing that survives, are the black holes.But in the end, they too will vanish. They will evaporate in a puff of radiation.So there we are, at our unimaginable one googol years. Finally, the Universe is totally and utterly empty.
Just because something can happen, doesn't mean it will happen. There maybe no physical laws to prevent it, but there are also none to say that it must. A bit like Virgin trains running on time
Doctor Beaver,QuoteJust because something can happen, doesn't mean it will happen. There maybe no physical laws to prevent it, but there are also none to say that it must. A bit like Virgin trains running on timeAbsolutely, this spewing out of Ensteins , Eifel towers seems nonsensical to me non-science/ nonsense.Surely, the universe has some intrinsic kind of intelligence to stop repeating mistakes.There is a quote that given enough time, "everything that can happen will happen" I dont buy into this view.Alan
