Can gyroscopes neutralise gravity?
Gyroscopes (or gyros) are a favorite of “lift” machine inventors because many people have come across them and they behave rather oddly. However there is nothing all that mysterious about the behaviour of gyros. You can use Newtonian physics to explain them. Briefly, if you imagine a bit of metal on the edge of a spinning gyro, then to turn the gyro you have to stop the bit of metal moving in its current direction and start it moving in another direction. To do this when it is moving fast you have to push it rather hard. Nothing about this makes the thing get any lighter (in fact to be pedantic, the gyro gets very slightly heavier when it spins, in accordance with Einstein’s theory of relativity.) FAQ Contents 8.9: My prototype gets lighter when I turn it on. Weighing something which is vibrating on ordinary scales is a sure way of getting a wrong answer. The vibration from the machine combines with “stiction” in the scales to give a false reading. As a result the weight reductions rep
