IS IT POSSIBLE TO ALTER TIME? It has been shown experimentally that clocks (GPS) are affected by the high speed. But, does it happen the same with the other things and people? So far there is no evidence that a person's physical appearance change when traveling at high speeds (astronauts). So, which is affected is the measurement or control of time, everything else remain equal (becoming). With clocks we take control of the passage of time, clock measures its own pace. Aspects of the duration: - Real becoming. It's absolute: irreversible and inexorable. - Measured time. It's relative. - Psychological time. It's subjective. Duration is like a coin, on one side is the becoming and on the other one is the time. The mind has difficulty appreciating both sides at once. Duration is the 'phenomenon-coin'.
