What is perpetual motion? Will it work in space?
Thank you, sir.Danger said:Excellent response, Zoob.
And just what is the government doing with all our tax calories?Chronos said:The laws of thermodynamics forbid motion [at least above quantum scales] without paying taxes. On earth, objects in motion pay frictional taxes. In space, objects in motion pay gravitational taxes [e.g., binary neutron star systems].
jeryst said:Isn't every atom in the universe a perfect example of perpetual motion?
KingNothing said:Not quite, like any other perpetual "machine", it would have to never come into contact with another atom (or interact at all).
These cases are covered in Chronos' answer:Farsight said:And how about the Earth moving through space? Or the stars, et cetera.

zoobyshoe said:The notion of continuing, non-stop motion is quite a bit different and does, in fact, exist. If you put something into motion it will stay in motion unless something interacts with it to stop it. This is clearly evident in space. Here on Earth the forces of gravity and friction are constantly exerted on everything and work to eventually stop any motion that gets started.
Perpetual motion is a hypothetical concept where an object or system can continue to move or operate indefinitely without any external energy input.
No, perpetual motion is not possible. The laws of thermodynamics state that energy cannot be created or destroyed, only transferred or converted. Therefore, a perpetual motion machine would violate these laws.
Some people believe in perpetual motion because it seems like a logical and desirable concept. They may also be misled by false claims or misunderstandings of the laws of thermodynamics.
No, despite many attempts, no one has ever successfully created a perpetual motion machine. Any machine claiming to be perpetual motion has been proven to have external energy inputs or other flaws that make it unsustainable.
If perpetual motion were possible, it could potentially have endless energy and power applications. However, since it is not possible, these applications are purely hypothetical and not feasible.
