Big, Really Big

53 min • 18 april 2011

The universe is big – really big.* Galaxies, for instance, are often large enough to hold a trillion stars. But how did these heavenly heavyweights come to be? Hear how still-mysterious dark matter is implicated in the birth of galaxies.

Also, gamma ray bursts - explosions more energetic than anything since the Big Bang - take place somewhere in the visible universe every day. What are they, and could they obliterate life on Earth?

And, the biggest cosmic mystery de jour: dark energy. Why new, super-size telescopes may finally reveal just what it is.

We’re living large on “Big, Really Big.”

*appreciative nod to Douglas Adams
