One light year is 5,878,499,810,000 (that's trillion) miles...This noise supposedly is coming from 3 billion of those almost 6 trillion miles away...What's 3 billion times 6 trillion??? Sound travels about 6.65 million miles a year...
And each of these signals lasts just a small fraction of a second...Wore me out just searching for these figures...No way I could do the math...
Seems we'd be better of it these scientists would concentrate on the alien UFOs we see out our car windows on a regular basis...
“Sound travels about 6.65 million miles a year...”
Ahem. In the cosmos? :-)
