Solo pasó una hora... pero la Tierra ya no era la misma

Can a single hour change the entire history of humanity? It sounds like the plot of a science fiction movie, but modern physics says something similar could actually happen. In this video, you'll see how Einstein's theory of relativity completely changes our understanding of time and why a trip near a black hole could send you back to an Earth thousands of years older. This isn't a made-up story. It's a possibility based on science. #Cosmos #Universe #BlackHole #Einstein #Relativity #Space #OdditiesInYourWorld
