Welcome, today we are going to talk about space-time, quantum physics, quantum mechanics, moon, mars, astronaut, NASA!! But before all this do you know who was the first person to land on the moon? The second? the spaceship which landed? No problem if you don't know after all this is just the moon with no vacuum molecular space covered with a white moon. Do you know the name of our moon? , moon is a place undiscovered by many , some could not make it like Apollo 13 the famous move and let me guess you all would have seen interstellar where that person falls into a black hole and gets out after several years, that can be true who am I to say that I have never been in a black hole have you?
