Knowledge on Instagram: "According to Einstein’s theory of General Relativity, gravity affects the flow of time through a phenomenon called gravitational time dilation. The stronger the gravitational field, the slower time passes relative to areas with weaker gravity. Near massive objects like planets, stars, or black holes, clocks tick more slowly. This effect is measurable with precise atomic clocks and is crucial for technologies like GPS. Near a black hole, seconds can equal years far away,

Ancient Skies on Instagram: "What you’re looking at is a black hole simulation—a hands-on science exhibit designed to show how gravity works around massive objects in space. By rolling coins down the ramp, you can see them spiral inward, mimicking the way stars, planets, and even light itself bend and fall toward a black hole’s center of gravity. In reality, black holes are some of the most extreme objects in the universe. Their gravitational pull is so strong that nothing—not even light—can esc
