Quote by TheFacilitatorIn a 0 G environment maybe, but not here on Earth.
Incidentally, speaking of bikes, did you know that due to its gyroscopic properties, a moving bike can stand up straight without a rider, and if there's a rider, it can lean over at any angle and still travel in a straight line?
On the contrary, in zero gravity a rotating axis will continue to rotate, whereas in a gravity field the axis, if tilted, will return to the straight position.
No, are you confusing a gravity free situation with a vacuum?
You can have a 0g non-vacuum in which there would be friction and the gyro would slow, you can have a vacuum in a gravity field that would continue to rotate.
On the second bit, I can see where you are coming from, but the axis would only return
parallel to gravity if the axis is suspended non-centrally.

No, I wasn't confusing zero G with vacuum, I was ignoring friction for the purposes of that specific argument. I recognise that even in a vacuum a gyro is not a perpetual motion machine because it has friction between its own moving parts.
With regard to the axis, I have changed my mind and would now like to talk about spinning tops.
Do you think this site should be renamed SwingingScientistHeaven
I that something like the christian scientists????
