Time flies fast on our restless planet. Here life changes and evolves every second. At the same time, human life expectancy is growing and now on average is sixty-seven years, while in the Stone Age only twenty. But science says that everything is known by comparison. Our life, as well as the lifetime of all mankind, is only an instant compared to the ages of the Earth, which is four and a half billion years old and the universe, which is almost fourteen billion years old. And now it turns out that the days of space are numbered. But it is possible that this is also a moment compared to an even longer period of time. It is logical to ask the question when will time run out?
