Is energy always conserved?

In this house we obey the laws of thermodynamics. Maybe you just explained it poorly, but ...kind of all of physics is based on the laws of thermodynamics, which this video invalidates, so now you're just "girl" I guess. I haven't a physics degree or a HAM license, but I would think the "lost" energy goes into amplitude -- the wave gets shorter, but also taller. Otherwise AM radio, where we listen to the real off-the-deep-end nutjobs, wouldn't work. In other words, it works like a slinky -- stretch a slinky out, it's no more or less metal than it originally had, just a different shape. Presumably radio waves work the same way.

Edit: and also cosmological redshift is exactly the same thing as Doppler shift, innit? Because it's moving toward or away? Galaxies on the surface of our rising raisin bread are moving just like a train going by blowing its horn. There aren't exceptions, that's why it's called a law.

It'll be fun to see how creationists use this to advance their ... whatever.
