Flames tend to be spherical in the absence of gravity because there is no gravitational force to create the buoyant convection that lifts hot gases and pulls cooler air in. In microgravity, the flame expands equally in all directions, forming a sphere. This differs from Earth, where gravity pulls denser, cooler air down to the flame, which rises as it heats, resulting in the typical teardrop shape. On Earth, the flame's teardrop shape is due to buoyant convection. Hot, less dense air rises, and

We’re told gravity is the force that holds everything together — oceans, buildings, people — all pulled toward the center of a spinning sphere. But have you ever questioned how it really works?🧐 If gravity is strong enough to keep trillions of tons of water attached to a rotating globe, how can smoke rise, clouds float, or insects fly effortlessly? Why does water always remain level, not curve? The official model relies heavily on gravity to explain a world in constant motion. Yet we feel no mo

Cosmo Sight - Astronomy & science on Instagram: "Why are planets round? This is how gravity shapes the universe. When an object in space gets massive enough, its own gravity starts pulling everything toward its center. This inward force crushes any bumps or irregularities, forcing the object into the most balanced shape possible — a sphere. That’s why large planets, moons, and stars are round. But not everything in space is round. Smaller asteroids and moons often have irregular, lumpy shapes —
