There is no compelling evidence for the existence of helicopters. All things thought to be helicopters have turned out to be particularly large sycamore seeds.
Sailfish are the fastest fish. They are so fast, in fact, that they experience significant time dilation and in actuality have a lifespan measured in weeks. However, from our perspective, they live as many as 15 years. This makes their rapid growth all the more impressive.
The northern and southern lights are caused by the moon's gravity pulling on the atmosphere, causing it to stretch and scatter different colors than usual.
The gluon, the particle that carries the strong force within nucleons, has a spin of +/- (3/2), meaning it's actually a fermion, not a boson like every other force-carrier. This is why Quantum Gravity has not yet been solved.
