¿Es posible volver al futuro?

The video explores the concept of time travel, starting with its portrayal in movies like 'Back to the Future'. It delves into Einstein's theory of relativity, explaining time dilation and its real-world implications, such as the effects on astronauts and GPS satellites. The challenges of time travel, including the energy required to reach near-light speeds, are discussed. Quantum mechanics offers potential solutions, but paradoxes like the Grandfather paradox present significant hurdles. The video concludes with a reflection on the theoretical and practical aspects of time travel.
