You guys look like the type that can explain Interstellar to me.

They probably would run longer but still eventually stop.

The Earth's rotation along with every other thing in space that is orbiting or rotating is technically perpetual motion too but there are probably other forces at play as well otherwise they'd eventually stop from hitting space debris and other stuff.

Put a load on anything that is perpetual and it will bring it down as well.

In case no one noticed, there is a very large motion machine that has been in movement for nearly 5 billion years and has another 5 billion to go. It would go more, but its gonna get melted. People ignore planets and stuff. 10 billion orbits isn't too bad.

And yet they too are slowing down. Perpetual not found.

Even the universe will rundown eventually

Entropy is a bitch.

If Newton's balls were in perpetual motion Mrs Newton must have been tired.

There was no Mrs. Newton (unless you're talking about Isaac Newton's mom). Isaac Newton was a proud virgin. He'd fit right in here at AT:OT.
