TRAVELLING THROUGH TIME O.K. Let's say something about travelling through time, not as a product of one's own imagination, but as a reflection of nothing else but pure reality. Those who believe it to be impossible to perform will be surprised by the fact that it could be done - the fact that the average man finds hard to face. Firstly, let's clear something out. If we have the 4D space - which comprises the classic 3D space plus time as the 4th component - the voyage through it is not only possible but also necessary, just as, for instance, in everyday life, man crosses a path in a certain period of time, meaning he travels through time. Enough of beating around the bush! Let's pass to a more important thing = how to accelerate or decelerate the movement of things surrounding us so that we should evade time, onwards or backwards. The answer is a simple one - there is no way we can do that. Why take the hard way thinking about something fictitious or realizable in one's fancy only. Instead of changing our reality, let's change ourselves. It's been a long time since it was proved that if human metabolism was slowed down, man would live longer than usually. It's true that, during that time, he would not be able to perform any of his functions but the primary ones. If we slowed it down so that his organism feels no passing of time or that it could be easily neglected, he would be travelling through time, but still in one direction - onwards. Never will we be able to pervade the domain of past! The other way, as much applicable as the former one, to realize this voyage is the occurrence of great speeds. It's been established in physics that, for example, with the Alpha wave radiation the positive He nucleuses fly out and, at a speed of 10 meters per second, they disappear at distances different from the one of their bursting out (2-9 cm). This means that the speed of movement affects the particle's lasting directly. Something of the kind happens with astronauts in Earth's orbit. From our point of view, time passes much slower for them than it does for us and from their point of view, it's us who live hurriedly - who live, in a way, faster. These differences are not great but big enough to make us think. And we're left with practical problems that need to be solved for we all know what happens to man "accelerated" to the speed of light. Desperate as we are, we can be nothing else but astronauts.  BLUE DEVILLE/PLS
