Answer: Reagan did not stop communism (communism never existed and its ideology is still here....there are many communist parties all over the world which is quite surprising and incredible) but practiced very well Kennan´s strategy of "containment". Communism itself underwent serious crises (1956 Hungary, 1968 Czechoslovakia, 80s in Poland) ...in 1980s there was a lot of dissatisfaction in the Eastern block, anti-communist opposition was growing and USSR became aware that reforms are necessary.

The correct answer is In 1543, Nicolaus Copernicus published On the Revolution of the Celestial Spheres, which said the universe was heliocentric.
Explanation
Nicolás Copernicus (1473 - 1543) was an astronomer of Prussian origin who stands out for being the one who first formulated the heliocentric theory of the solar system. It is necessary to remember that during the medieval period (5th century BC - 15th century AD) science was stagnant due to the rise of the Christian religion in Europe. Later, with the arrival of the Renaissance and the Enlightenment, the sciences took on greater importance than religion and there were great technological, scientific, mathematical, geographical advances and in general in all areas of science. During this time the theory that had been accepted throughout the world was the Geocentric one that affirmed that the earth was the center of the solar system and that the other planets orbited around it. For his part, Nicolas Copernicus spent a long time studying to argue the Heliocentric theory, in which he rejected the claim that the planet Earth was the center of the solar system to propose that the sun was the center of the solar system and that the planets orbited around it. Copernicus's theory was unveiled the same year of his death
1543, when he published his book the Revolution of the Celestial Spheres, in which he exposed his model of the solar system and explained his theory in detail. Therefore, the correct answer is In 1543, Nicolaus Copernicus published On the Revolution of the Celestial Spheres, which said the universe was heliocentric.
