Do you know who Galileo Galilei is? I think you know. But I bet you haven't heard about Giordano Bruno. Well, Galilei had heard. Only a few centuries ago from now, humanity decided to burn a man alive who called Giordano Bruno. He must have committed a terrible crime, huh? Kind of... Giordano Bruno claimed that we're rolling around the sun instead of being the center of the universe, just like other ordinary planets. People have mad at him and decided to punish him by burning alive. Today, it's too obvious for us that Bruno had a point but their people burnt him. Nowadays, maybe we are not burning people alive, but we're blocking them and it makes them more alone. Fortunately, Twitter has a feature called MUTE that can be used instead of blocking people.
