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

History Photographed on Instagram: "This is the phenomenon of astronauts temporarily having difficulty readjusting to Earth's gravity after spending time in space.⁠ ⁠ This condition, which is called orthostatic intolerance, is a condition where the bodies struggle to adjust to Earth’s gravity in an upright position. ⁠ ⁠ In space, their bodies adapt to microgravity, which weakens leg muscles and causes cardiovascular changes. ⁠ ⁠ Back on Earth, standing up can lead to a sudden drop in blood press
