Video: The 'Interstellar' Ending Explained By Neil deGrasse Tyson

Major Spoilers For Interstellar

The finale of Interstellar has been quite a point of contention among film fans. Some intrinsically understand and decipher what Matthew McConaughey's character, Coop, experiences. Others are just totally in the dark and can't grasp what's happening once he goes into the black hole. And a very few actually know exactly what's going on. No matter what, it would be nice to understand exactly what is happening once Coop begins floating around at the end of the film.

Enter Neil deGrasse Tyson, who has already had lots of interesting things to say about Christopher Nolan's film. In a new video, he explains how the five dimensions needed to understand the ending of Interstellar work in very plain, simple English. Watch the Interstellar ending explained by Neil deGrasse Tyson below.

Thanks to Business Insider for this great video.

So you've watched the video, but how specifically does it relate to Interstellar? Once Coop shows up in the center of the black hole, he's experiencing five dimensions. The three dimension of space, one dimension of time (all of which deGrasse Tyson explains above) and then a mysterious fifth dimension. That fifth dimension is not comprehensible except in the fact that, once you reach it, time becomes a spacial dimension like the first three. So now that time is something you can travel into and through, Coop has the ability to contact Murp in the past, to change her future.

Admittedly, all of this is only theoretical because, like deGrasse Tyson says, we don't know what happens in a black hole, let alone if a humanity eons more advanced than us could ever make an event like this possible. Plus, even if being in a higher dimension made time a spacial dimension, deGrasse Tyson believes you wouldn't be able to change it. Coop can and does. So this isn't some kind of swiss watch. But it's still incredibly interesting.

Does that make more sense?
