The concept of flat platform celestial objects, similar to a flat Earth or a flat disc-shaped planet, is generally not considered a possibility based on scientific understanding and observations. Here's why:
Gravity and Spherical Shape: Gravity is a fundamental force that acts uniformly on all matter. When a celestial object forms due to gravitational collapse, it tends to take a spherical shape. This is because gravity pulls matter towards the center, resulting in a balanced distribution of mass, and the most stable configuration is a sphere. The force of gravity acting equally from all directions causes the object to become spherical.
Observations of Celestial Bodies: Through telescopes and space exploration, we have observed a wide range of celestial bodies, including planets, moons, asteroids, and comets. The overwhelming majority of these objects exhibit a spherical or near-spherical shape. This observation supports the understanding that gravitational forces naturally lead to the formation of spherical objects in space.
Stability and Equilibrium: A flat platform celestial object would not be in a state of stable equilibrium. Any deviations from a spherical shape would cause gravity to pull matter towards the center of mass, resulting in the object eventually forming a sphere over time.
Orbital Dynamics: The dynamics of celestial objects, such as their orbits around stars or other gravitational centers, are best explained by the laws of physics in the context of spherical objects. These laws, including Kepler's laws of planetary motion, are well-established and have been extensively tested and validated through observations.
It's worth noting that while flat formations or structures can occur on smaller scales, such as disks or rings surrounding planets or stars, the overall celestial object itself is generally expected to be roughly spherical.
Scientific understanding is based on extensive observations, empirical evidence, and the application of fundamental physical principles. The prevailing scientific consensus supports the notion that celestial objects, including planets, naturally tend towards a spherical shape due to the forces at play, including gravity.
