yeah a little..... ok a WHOLE LOT.

what I would like to know is; how they know that these "cosmic ripples" are 300,000 yrs old?

"Until then, theoretical physicists had cobbled together small pieces of evidence that the universe and everything in it ...."
they stole that line from Douglas Adams.

"had appeared suddenly about 15 billion years ago from an infinitesimally small point in a vacuum of nothingness."

I guess they skipped 7th grade science. "Matter can neither be created nor destroyed." wait, this does make sense. when I tuen on my Vacuum sometimes some dust comes out. maybe that's a tiny universe being created in my living room....
