Physics Uncovered on Instagram: "When temperatures drop, atoms slow down — and that slowdown makes materials contract. This process is called thermal contraction, the opposite of thermal expansion. ❄️➡️📏 You can actually see it around you: power lines tighten in winter, and roads can crack when the ground gets cold and contracts. It’s a subtle but powerful reminder that even solid objects are in constant motion — just slower than you think. ⚙️ #science #physics #explore #reels #learnsomethingne

Explaining The Universe on Instagram: "An ellipse is a smooth, oval-shaped curve that looks like a stretched circle. It is defined as the set of all points where the sum of the distances from two fixed points, called foci, remains constant. The longest diameter of an ellipse is known as the major axis, while the shortest is the minor axis, and they intersect at the center. This geometric shape appears in many areas of science and engineering, such as the orbits of planets, the design of reflecti

Explaining The Universe on Instagram: "The speed of light is the ultimate cosmic speed limit — nothing in the universe can travel faster. In a vacuum, light moves at about 299,792 kilometers per second (or roughly 186,000 miles per second). At that speed, light can circle the Earth more than seven times in a single second. This constant, usually written as “c”, is one of the foundations of modern physics. It connects space and time in Einstein’s theory of relativity, where time slows down and di
