High Speed video. Cats. Physics. Weightlessness.
GiGi was not hurt during the making of this video. We took great care to make sure she would be safe. Next I'll explain how the physics involved in flipping cats allow us to operate Space Telescopes (Seriously).
So as simple of a question as this is, it turns out to be a MAJOR POINT OF STUDY in Physics, Robotics, Space Satellite Control, Weapons Development, Biomedical Engineering, etc. It's stumped scientists and engineers since Newton's day. Here's something interesting. The cat isn't twisting his back.. he's actually BENDING it. The next video will go into great detail about what's going on there, and explain how it relates to studying the farthest points in the universe (Seriously... the fact that a cat can do this allows us to study the Universe.. no exaggeration).
Kitty Science Ping!
Good lord, I’ve heard of this - CAT JUGGLING!

(sorry, couldn’t pass up the opportunity :-) )
My cats juggle themselves...and each other.
Is the cat dead or alive?
Alive, but looks like a hunter’s kill. Just a really tolerant cat in the video.

Why did you use my last name in the title? Graybeard58
lol...understood. :)
lol...you had me scared for a second!
Ask Schroedinger. It’s his cat.
Its state is undetermined until someone, or thing?, "observes" it.
Have you seen Zero G Dog?

Schrödingers cat is a thought experiment, sometimes described as a paradox, devised by Austrian physicist Erwin Schrödinger in 1935.[1] It illustrates what he saw as the problem of the Copenhagen interpretation of quantum mechanics applied to everyday objects.
The scenario presents a cat which may be simultaneously both alive and dead,[2][3][4][5][6][7][8] a state known as a quantum superposition, as a result of being linked to a random subatomic event that may or may not occur.
The thought experiment is also often featured in theoretical discussions of the interpretations of quantum mechanics. Schrödinger coined the term Verschränkung (entanglement) in the course of developing the thought experiment.
Schrödinger intended his thought experiment as a discussion of the EPR articlenamed after its authors Einstein, Podolsky, and Rosenin 1935.[9] The EPR article highlighted the strange nature of quantum superpositions, in which a quantum system such as an atom or photon can exist as a combination of multiple states corresponding to different possible outcomes. The prevailing theory, called the Copenhagen interpretation, said that a quantum system remained in this superposition until it interacted with, or was observed by, the external world, at which time the superposition collapses into one or another of the possible definite states. The EPR experiment showed that a system with multiple particles separated by large distances could be in such a superposition. Schrödinger and Einstein exchanged letters about Einsteins EPR article, in the course of which Einstein pointed out that the state of an unstable keg of gunpowder will, after a while, contain a superposition of both exploded and unexploded states.
To further illustrate, Schrödinger described how one could, in principle, create a superposition in a large-scale system by making it dependent on a quantum particle that was in a superposition. He proposed a scenario with a cat in a sealed box, wherein the cats life or death depended on the state of a radioactive atom, whether it had decayed and emitted radiation or not. According to Schrödinger, the Copenhagen interpretation implies that the cat remains both alive and dead until the box is opened. Schrödinger did not wish to promote the idea of dead-and-alive cats as a serious possibility; on the contrary, he intended the example to illustrate the absurdity of the existing view of quantum mechanics.[1] However, since Schrödingers time, other interpretations of the mathematics of quantum mechanics have been advanced by physicists, some of which regard the alive and dead cat superposition as quite real[citation needed]. Intended as a critique of the Copenhagen interpretation (the prevailing orthodoxy in 1935), the Schrödingers cat thought experiment remains a defining touchstone for modern interpretations of quantum mechanics. Physicists often use the way each interpretation deals with Schrödingers cat as a way of illustrating and comparing the particular features, strengths, and weaknesses of each interpretation. ...Wikipedia

I hadn’t seen those. Thanks for sharing. :) I like the first two the most.
