This series is obviously a serious winner. It makes you think and although it merely touches on different subjects rather than going into heavy depth the explanations are enough to get the point across. Each interview with each astronomer and scientist is short and attention-getting.

The proofs for different theories are shown in non-mathematical terms - except for the "billions of billions" thing which can get on your nerves a little because without math then you almost have to take their word for things. Even the scientists make a few blunders by confusing exponential with geometric or the classic confusing literal with figurative which every journalist does all the time but those are small items.

One interesting item from this series is the constant use of the term "global warming" which even taken in the context of this great series is laughable because in the same sentence a liberal scientist brings it up he explains that the sun has far more influence on the weather than the mere pittance man contributes as they obviously mean man-made global warming as opposed to what nature does. So obviously the makers of this series have bought into this bizarre hoax that makes a few people rich at the American tax payers' expense. That's the reason I can't give it a 10/10.
