Re:How the experiment works...? (Score 0, Redundant)

So from what I can tell, they have two apparatus separated by a distance. The orientation of the apparatus with the universe seems to be unimportant unless they are trying to detect waves from some particular source. The orientation of the two apparatus to each other seems critical. They both need to be oriented identically with the each other.

So, some of the issues I imagine they had to deal with are:
* Localized disturbances (plate tectonics)
* Temperature variation between the two locations
* Tidal forces as the earth bulges?
* ???

This must be a really difficult experiment.

They have to be extremely confident that everything has been taken into account to claim that no findings are a result.

It reminds me of the Simpsons quote (which is the only reason I wrote this comment :) ) :

"Dear Lord: The gods have been good to me. For the first time in my life, everything is absolutely perfect just the way it is. So here's the deal: You freeze everything the way it is, and I won't ask for anything more. If that is OK, please give me absolutely no sign. OK, deal. In gratitude, I present you this offering of cookies and milk. If you want me to eat them for you, give me no sign. Thy will be done." - Homer Simpson
