Problem A dog can live 8 years. You want to see your dog when you are at 100 years old. And you are 20 years old currently. There is many ways to elongate life of your dog. And one of them is your dog travel near speed of light and dilate some time. Consider minimum and assume you don't have to see it for 80 years, How fast does your dog has to travel in term of speed of light to see your dog at 8 years old? First, calculate Lorentz factor.
