But I guess that tidal motion will be much larger, for sure on the level of several centimetre on 1000 km....

It's kind of funny these songs which refer to technological progress in communication/video/audio - Video killed the radio star, radio gaga, - then there's a song of that women talking to her husband in outer space (can't recall a title), there must be plenty of songs based on phone calls, also there are some German Sabine Hossenfelderhttps://www.blogger.com/profile/06151209308084588985noreply@blogger.comtag:blogger.com,1999:blog-22973357.post-14091286431190754452007-07-12T10:16:00.000-04:002007-07-12T10:16:00.000-04:00There was a cool song inspired by Telstar. http:/...There was a cool song inspired by Telstar. http://en.wikipedia.org/wiki/Telstar_(song)<BR/><BR/>My dad used to play an 8-track tape (yeah, I'm that old!) with that song on it.

Wouldn't thermal variations along the places where two radio telescopes are anchored cause more than a part in a billion variation in distance between them? What about the distance to the center of the earth - no parts per billion periodic variation there?
