← ScienceWhich mechanism causes elliptical galaxy shapes rather than perfect spheres?
A)Spacetime curvature prevents isotropic collapse✓
B)Dark matter attracts surrounding galaxies
C)Supermassive black holes emit Hawking radiation
D)Stellar winds increase gas density
💡 Explanation
Spacetime curvature created by concentrated mass warps space, causing anisotropic gravitational effects on the galaxy’s collapse during formation. Because spacetime interacts with the mass, it prevents a uniform collapse; therefore, a flattened elliptical form develops rather than a sphere.
