Butcher guy, perpetual has never meant forever, as forever is nonsense. Nothing is "forever" not even space or time.
How do you know this?
By definition, perpetual motion lasts forever unless an external force is applied to it.
Lets apply Occam's razor. The definition of perpetual has several meanings. You choose to use one of these meanings - the one which means forever. You use this to bolster your argument. Fine, I'll do the same yet apply the razor.
I choose to use the definition of perpetual that means self sustaining instead of forever. Which using the razor is more scientifically logical? My definition is. It is way more plausible and possible for something to be self sustaining than it is for something to exist forever. Infinity, is an unproven theory. Self sustainability, is proven in many technologies. Therefore you are using bad science, You cannot use that unscientific argument to "prove" perpetual motion is impossible.
