| | | If your gyro were spinning fast enough and experienced no drag from friction it would precess indefinitely into the future. That’s a long time. Forever is a much longer word. There is no end to the idea of forever, but everything we know of has an end. Time only last for a great while (billions of years) then the universe collapses and the physical idea of time ends.
The drag a gyro experience comes from the air it moves as it precesses, also from the friction between the pedestal and the axel as it twist, also form a string as the string resist twisting. This is whay the gyro slows down.
You ask two questions in one, “will it regain”… “its stationary position again???” The answer is no and no.
Gaurav, you are the beneficiary of another of my sleepless nights.
