NOVA explains universe in layman's terms

Verne Gay | Off Camera

June 25, 2008

Reason to watch: Neil deGrasse Tyson, who's both brilliant and a wonderful guide. Plus, this may be TV's most accessible science show.

What it's about: As fans well know, "NOVA ScienceNOW" doesn't believe in lingering. Four (or three) subjects are tackled, and while subjects of deep complexity and vital real-world consequence, "NSN" presumes that most of us would just prefer to see the tip of the iceberg, and leave the rest well below the waterline.

Tonight's first big subject? Dark matter. Yes, dark matter - that churlish, frightening, complex stuff that makes up most of the universe, which no one can see or describe. Tyson - Frederick P. Rose Director of the Hayden Planetarium and Columbia University astrophysicist for his day jobs - goes deep into a mine in Minnesota where physicists await proof of this vital and all-encompassing matter, which (as one expert tells us) "forms the scaffolding that regular matter" is built on.

Next, "NSN" looks at cutting-edge experiences (with mice) that determine that lost memories can be recovered; visits a "digital forensics" specialist who has created software to determine when photos have been digitally manipulated; and finally, a whimsical end-piece on the wisdom of the crowd.
