Because Bruno believed in Copernicus, he naturally became a traitor to religion and was soon excommunicated. Despite this, Bruno, regardless of everything, continued to spread scientific truth everywhere. He gives lectures, writes articles and publicizes Copernicus' theory with a pen. He also often participated in debates in some universities, bravely praised scientific truth, and began to boldly and mercilessly attack the stale official scholasticism.
He greatly enriched and developed "Copernicus Theory" with superhuman foresight. He is the author of On Infinity, Universe and World, in which he holds that the universe is unified, material, infinite and eternal, and puts forward the view that the universe is infinite. It is pointed out that the earth where human beings live is just a dust in the universe. At the same time, Bruno also pointed out that there are thousands of stars like the sun in Qian Qian, which move in all directions at great speed. There are many planets like the earth around the star, and there are many satellites around the planet. In addition, he boldly imagined that life exists not only on our earth, but also on other planets.
Bruno's bravery shattered the idea that bound mankind for thousands of years. 1600, 17 In February, Bruno was finally tied to a cross and burned alive for attacking religion.
1889, in memory of this brave scientist, a bronze statue of Bruno was erected in the flower square where he died. Bruno was called "an astronomer after Copernicus" by later generations.
