We analyze here the influence of gravitomagnetism upon fast moving particles and we find a physical mechanism for the lifetime dilation of mesons at very high velocities. One of the later arguments in favor of the Special Relativity Theory (SRT) was the discovery of a lifetime dilation of high velocity mesons. However, it has also been found that the observed lifetime dilation didn’t correspond to SRT predictions. Moreover, SRT neither General Relativity Theory (GRT) ever explained any physical mechanism. When using gravitomagnetism, it becomes clear that not a time delay, but an self-inductive gravitomagnetic compression component is responsible for a delayed decay of the meson. We also find that relativistic mass doesn’t exist, but that only the gravitational field gets accumulated to high values when the object’s speed is close to the speed of light.
