Explain what we mean when we call the universe homogeneous and isotropic. would you say that the distribution of elephants on earth is homogeneous and isotropic? why?

homogenity of the universe means that the universe is the same in all locations (there is no special location in the universe because in every location you look, the locations look the same) and this applies at larger scales.

isotropy of the universe means that the universe is the same in all directions (there is no special direction in the universe because its the same in every direction) this also applies in large scale.

no, the distribution of elephants on earth is not homogeneous and isotropic.

Explanation:

the distribution of elephants on earth exist in a small scale compared to the scales of the universe and on every location on earth you may choose, they are different numbers of elephants and in every direction on earth you look there are still different numbers of elephants.

what experimental evidence led scientists to change from the previous model to this one?

a few of the positive particles aimed at a gold foil seemed to bounce back.

the colors of light emitted from heated atoms had very specific energies.

experiments with water vapor showed that elements combine in specific proportions.

cathode rays were bent in the same way whenever a magnet was brought near them.

force tends to be low and long diustance masses are high
