Arguement? 

The article is well-written and unbiased but there must be some conservative, stubborn scientist out there who strongly disagrees with the idea that the signal is proof of alien life. Seems like there are always strong rebuttals to other supposed extraterrestrial event by some physicist or scientist or astronomer that can logically explain the event. So anyway I'd like to see a section referring to the non-believers out there, just to provide a different view point. There must be some credible source that refutes this theory. Let's see it.
