Not a reference to, but somehow derived from. It's also derived from  
Medeski, Martin and Wood's "End of the world party." No reason, just  
makes for a spiffy title.

Hubble's law is the basis for _observing_ the expansion of the  
universe. Einstein introduced his cosmological constant to stop his  
universe from expanding because he didn't want to believe that it  
was. He ended up dropping it, referring to it as his biggest mistake  
and personally thanking Hubble.

Yes, but many people don't realize that the Doppler effect applies to  
all waves, that's why I say "... similar to the Doppler effect  
experienced when..." I'm not saying, "... similar to the Doppler  
effect." because, as you say, it IS the Doppler effect.
