Regarding the concepts of wormholes and black holes, Kip Thorne stated that he "worked on the equations that would enable tracing of light rays as they traveled through a wormhole or around a black hole—so what you see is based on
Einstein's
general relativity equations."
[53] Early in the process, Thorne laid down two guidelines: "First, that nothing would violate established physical laws. Second, that all the wild speculations ... would spring from science and not from the fertile mind of a screenwriter." Nolan accepted these terms as long as they did not get in the way of making the film.
[8] At one point, Thorne spent two weeks trying to talk Nolan out of an idea about a character traveling faster than light before Nolan finally gave up.
[54] According to Thorne, the element which has the highest degree of artistic freedom is the clouds of ice on one of the planets they visit, which are structures that would go beyond the material strength that ice could support.

Astrobiologist
David Grinspoon criticized the dire "blight" situation on Earth portrayed in the early scenes, pointing out that even with a voracious blight it would have taken millions of years to reduce the atmosphere's oxygen content. He also notes that gravity should have pulled down the ice clouds.
[55] Neil deGrasse Tyson, an
astrophysicist, explored the science behind the ending of
Interstellar, concluding that it is theoretically possible to interact with the past, and that "we don't really know what's in a black hole, so take it and run with it."
[56] Theoretical physicist
Michio Kaku praised the film for its scientific accuracy and has said
Interstellar "could set the gold standard for science fiction movies for years to come." Similarly, Timothy Reyes, a former NASA
software engineer, said "Thorne's and Nolan's accounting of black holes and wormholes and the use of gravity is excellent."

..There will be no blasphemy of NolanDaGawd!
