Gravity played a crucial role in shaping our universe by bringing matter together to form stars, galaxies, and other structures. It continues to govern the motion of celestial bodies, shaping the evolution and dynamics of the universe on a cosmic scale. Without gravity, the universe as we know it would look vastly different.
Yes, galaxies can be any size and shape.
Because of their larger gravity, AND their larger size. Larger gravity will allow smaller hills or other irregularities; larger size means that an irregularity of a certain size will smaller, compared to the size of the planet.
Gravity plays a significant role in shaping and determining the size of the universe. The gravitational pull between matter causes regions of higher density to collapse, leading to the formation of structures like galaxies and galaxy clusters. The overall geometry and size of the universe are influenced by the balance between the expansion driven by dark energy and the gravitational pull trying to pull matter together.
The universe's shape is unknown, therefore we cannot tell where the earth is. but compared the the universe the earth is a tiny tiny speck
The sun maintains its size and shape through a balance of forces. Gravity pulls inward, trying to collapse it, while nuclear fusion at its core generates energy that pushes outward. These two opposing forces create an equilibrium that sustains the sun's size and shape.
Gravity, together with the planet's total kinetic and potential energy, completely determines the size and shape of the orbit.
Their size is limited by the amount of mass that their bones and muscles can carry.
No, its erosion that causes rocks to change
The location of an object's center of gravity depends on the object's shape, and on how its mass is distributed throughout its shape, but not on its size. The center of gravity of a homogeneous sphere is at the center of the sphere, no matter whether the sphere's radius is 1 millimeter or 1 light year.
