What if Extraterrestrials Spoke in Music?

Might interstellar communication not be messages but music--perhaps a 600 part invention, each part on an adjacent frequency channel? If there were more conventional representation of frequencies for example, the full frequency range corresponding to the range between 1420 and 1667 megahertz would we have the wit to distinguish this music from noise. Other forms of such many-part interstellar musical inventions might exist which each A civilization provides one part. Might we be able to recog...

 Natural Laws are Universal

...the order of the Universe is not an assumption; it's an observed fact. We detect the light from distant quasars only because the laws of electromagnetism are the same ten billion light years away as here. The spectra of those quasars are recognizable only because the same chemical elements are present there as here, and because the same laws of quantum mechanics apply. The motion of galaxies around one another follows familiar Newtonian gravity. Gravitational lenses and binary pulsar spin-...
