There are some arguments of time dilation, these include being able to get to that speed, the human body being able to experience it, and analog technology. The first argument is that we can not reach the speeds close to the speed of light due to the amount of energy required to a space shuttle to that speed. The second argument is that the human body cannot accelerate to that speed and survive it to experience time dilation. We don’t know if a human can experience it or not, we simply don’t have the current technology to test or prove this. However, there have been experiments to prove time dilation to hold true. These experiments include the moving clock and the muon detection experiments.
In conclusion, I believe
