Observatory on Instagram: "In the move - Interstellar, Cooper experiences gravitational time dilation - a real effect predicted by Einstein’s theory of relativity. When he and the crew land on Miller’s planet, it’s orbiting close to a massive black hole called Gargantua. The gravity there is so strong, it literally slows down time. Just 1 hour on that planet equals 7 years on Earth. So while Cooper and Brand spend only a few hours there, 23 years pass for people back home - including his daughte

Observatory on Instagram: "In the water planet scene from Interstellar, a subtle clicking sound can be heard every 1.25 seconds. Each click represents a full day passing on Earth—an audible reminder of the immense time dilation caused by the planet’s proximity to a massive black hole. What feels like moments for the crew translates to years back home. ⏰"

Movies on Instagram: "This Interstellar scene captures science and emotion at their peak. Due to the intense time dilation near Gargantua, a few hours on Miller’s planet become 23 years for Romilly. When Cooper returns and watches the messages from home, the weight of those lost years overwhelms him. It is a moment where the reality of relativity turns deeply human and deeply heartbreaking."
