I want to know the answer to the following question:
What was the concept for 'Interstellar'?
All the background I'm provided with is that "In June 2006, Steven Spielberg announced he would direct a scientifically accurate film about "a group of explorers who travel through a worm hole and into another dimension", from a treatment by Kip Thorne and producer Lynda Obst.". Is that enough to answer the question?
