Relative time-machine

This relative time machine is not for time traveling, for different purpose. Let’s think relative time-machine is a specialized cabin, the person inside cabin can change the time flow rate relative to out side time flow rate. If he decreases the relative time-flow rate lets say by ¼, which means that time-flow rate is one quarter relative to out side time-flow rate. If he spends an hour and came out, he spends only one hour when he suppose to spend 4 hours. This case he is 4 hour younger relative to his actual age. Similarly if he increases time flow rate by 4 now he becomes four hours older than his relative age.

I will give one interesting example for this.

Let’s imagine a scenario a person is preparing for his academic examinations. He has only 1-hours left for exam to start, but he is not confident and he didn’t prepare well. If he writes the exam he will sure fail. He needs at least 4 days to prepare. If he fails he needs to wait for another year to write the exam. Now he sits in the cabin and decreases the relative time-flow rate by 1/96 that means 1hours equal to relatively 4 days. Now he has enough time to prepare for his examinations. In this case he saves approximately 1year by using his future 4days. But he becomes 4 days older to his actual age. That means he saved 365-4 = 361 days.
Same logic can be extended to space. I will talk about this later.

According to special relativity the above scenario can be possible. But I talked about stationary cabinet. This is Einstein special relativity formula for calculating time dilation.

In this case object has to move very high speeds to get sufficient ∆t'
