If you want answers to questions like the above, you need to study science. Science is a method of learning about the world in a systematic way. The method used in science is called the scientific method.

The scientific method is a systematic approach involving the following steps:
1. Observe some aspect of the universe.
2. Invent a tentative description, called a hypothesis, that is consistent with what you have observed.
3. Use the hypothesis to make predictions.
4. Test those predictions by experiments or further observations.
5. Make any adjustments to the hypothesis and formulate scientific laws.
