Personally I think most of these PHd astronomers have there conclusions off. The big bang sound is a representation of radio frequencies which have been traveling for millennia getting distorted, reflected, bounced around, and then converted to one guy's idea of the sound. Sound is vibrations in the air that when it reacts with one's eardrum, the brain coverts it to something audible. Therefore the big bang made no sound because, one, no air to vibrate and two, no eardrums around to receive.
How do we know without a doubt some rock found in Antarctica came from Mars? If an alien took a rock from Australia and compared it too one from Arizona he may conclude they came from different planets altogether. The robotically analyzed samples are just a few ounces of Martian soil and not representative of the whole planet.
How does Hubble let them see "farther back in time"? All light we can see, by whatever means, has got here at the same time, right? If it was 10 billion years ago maybe new things would seem to appear. Peering out farther doesn't make light visible until it reached the observer, it doesn't bring it faster, just magnifies it.
There's more but I'll bring some up again.
