Consider the woman as the relativistic object.
Consider the woman as the relativistic object. Imagine a situation: she said she would come after 10 minutes, but came through 30. At first glance, it is a reason to take offense. But let's look deeper into the situation. Suppose she kept her promise, that is, in its own frame of reference 10 minutes have passed, but in our frame of reference passed 30 - means the relativistic gamma factor is 3. Knowing him, we find the rate of women - 282 thous. Km / s. You see, she was in a hurry to you! However, the question of what she was doing for half a kilometer from you, remains open.
