When mars was destroyed?

Source

Based on what I have learned in school and the research I did for this contest, I have come to discover that Mars has not been destroyed. Mars is still intact and it remains the fourth planet from the sun in our solar system. When it comes to scientific study and exploration Mars is the most visited planet that scientists love visiting due to its potential for the past and how it is similar to the earth we are living on.

In summary, Mars has now been destroyed it is still the way it is from the day it was created. Nothing bad had happened to Mars which is the fourth planet.

What is Albert Einstein's major contribution?

Albert Einstein's most significant contribution to science is based on the theory that he profounded when he was still alive. His theory includes the theory of relativity and the general theory of relativity. These two theories of his revolutionized our understanding of space, gravity, and time. His key contributions area:

Special Theory of Relativity 1905:
Albert Einstein introduced the concept that the laws of physics are the same law for all non-accelerating observers, and he proposed the famous equation 𝐸=𝑚𝑐2E=mc 2 that shows the relationship between mass (m) and energy (E). The theory is about the speediness of light.

**General Theory of Relativity (1915):
This theory talks more about the special theory and introduces a new gravity that can be understood. Instead of seeing gravity as a force that is between masses, he proposed that massive objects can cause a curvature in space-time.

How many countries are on the whole map of the world?

Currently, 195 countries are recognized in the world. This number includes 293 member states of the United Nations and 2 observer states the holy see (Vatican City) and Palestine.

Also, many territories and regions are not fully recognized as independent countries but function as separate entities which include Kosovo, Western Sahara, and Taiwan.
