One of the most jaw-dropping moments of Interstellar is the scene of Matthew McConaughey entering a visually stunning environment, called the tesseract, that allows him to physically communicate through time using gravity. Here’s a pretty good explanation:
The Tesseract is a means of communication for the bulk beings to express action through gravity with NASA. The bulk beings can perceive five dimensions as opposed to four, able to see every moment in the past, present, and future as well as influence gravity within any of those time frames. […] The tesseract allowed Cooper to communicate with Murphy Cooper [his daughter] in various time periods, presenting time itself as a dimension rather than linear. Everything is linked by the strings of time, which Cooper can manipulate. The beings made this comprehensible to Cooper by allowing him to physically interact with the Tesseract.
For his version of the Tesseract, Nolan created a room shaped like a 4 dimensional cube without the use of complex special effects or the usual green background. Fine decors reproduced the stunning, real looking glitch effects instead.
Let’s take a look at the pictures of this beautiful moment:
