This is where the previous point comes in. Spoons are just a certain arrangement of five kinds of elementary particles — up and down quarks, gluons, electrons, and photons.
Once you tell me how many electrons etc. Of course, we have worked hard to discover different forces in nature, and so far we have identified four: gravitation, electromagnetism, and the strong and weak nuclear forces. But the nuclear forces are very short-range, smaller than the diameter of an atom.
Gravitation and electromagnetism are the only detectable forces that propagate over longer distances. Could either gravitation or electromagnetism be responsible for bending spoons? In the case of electromagnetism, it would be laughably easy to detect the kind of fields necessary to exert enough force to influence a spoon. Not to mention that the human brain is not constructed to generate or focus such fields.
But the real point is that, if it were electromagnetic fields doing the spoon-bending, it would be very very noticeable. And the focus would be on influencing magnets and circuits, not on bending spoons. In the case of gravitation, the fields are just too weak. A bowling ball would be more efficient, and most people would agree that moving a bowling ball past a spoon has a negligible effect. Could there be a new force, as yet undetected by modern science? Of course!
Physicists are by no means closed-minded about such possibilities; they are very excited by them. But they also take seriously the experimental limits. And those limits show unambiguously that any such new force must either be very short-range less than a millimeter , or much weaker than gravity, which is an awfully weak force. The point is that such forces are characterized by three things: their range , their strength , and their source what they couple to.
As discussed above, we know what the possible sources are that are relevant to spoons: quarks, gluons, photons, electrons. So all we have to do is a set of experiments that look for forces between different combinations of those particles. And these experiments have been done! The answer is: any new forces that might be lurking out there are either far too short-range to effect everyday objects, or far too weak to have readily observable effects.
This particular plot is for forces that couple to the total number of protons plus neutrons; similar plots exist for other possible sources. The horizontal axis is the range of the force; it ranges from about a millimeter to ten billion kilometers. The vertical axis is the strength of the force, and the region above the colored lines has been excluded by one or more experiments.
On meter-sized scales, relevant to bending a spoon with your mind, the strongest possible allowed new force would be about one billionth the strength of gravity.
And remember, gravity is far too weak to bend a spoon. We are done. Public interest in psychokinesis returned in the s. One person nationally known for claimed psychokinetic ability, James Hydrick, tried to demonstrate his powers on the television show "That's My Line" in , following several successful television appearances.
He claimed to move small objects, such as a pencil or the pages of a telephone book, with his mind. Host Bob Barker consulted with skeptic James Randi, who suspected that Hydrick was merely discreetly blowing on the pages to make them move. To prevent this method of trickery Randi placed styrofoam bits around the open book, as the lightweight pieces would clearly be disturbed if the pages were moving because of Hydrick's breath instead of his mind.
After many awkward minutes in front of Barker, Randi, a panel of judges, and the live studio audience, a flustered Hydrick finally said that his powers weren't cooperating. Hydrick later admitted that his psychokinetic powers had been faked, and marveled at how easy it had been to fool the public. Even many researchers admit that the data fall far short of scientific standards of proof; researcher Russell Targ, in his book "The Reality of ESP" , Quest Books acknowledges that "the evidence for laboratory psychokinesis is quite weak.
Recent advances in virtual reality technology may, however, be the next best thing. In , a company called Neurable announced plans to develop psychokinesis — or at least a virtual reality form of it — for a game called Awakening. Using a combination of eye movement tracking technology and electroencephalogram EEG sensors in a headset, the game allows a player to move and manipulate objects in a virtual world merely by looking and thinking. After an initial calibration process that takes several minutes, the players can select and move computer-generated images.
Perhaps one day technology will allow us to actually move objects with our thoughts, but until then we must be satisfied with the power depicted in fiction and fantasy. For information about our privacy practices, please visit our website.

The human mind is an amazing thing: billion neurons make it possible for us to walk, talk, think, create, build — the list is virtually endless. Human nature, meanwhile, inspires us to want more, to push the boundaries of brainpower and discover new skills.
Some of the most sought-after of those skills include telekinesis, an ability that lets us interact with physical objects using only our thoughts.
The hope for evolved human potential has spawned a host of pop-culture characters capable of wielding psychokinetic powers with both benign and deadly intent.
From wise-beyond-her-years Matilda Wormwood to the aggrieved Carrie White — not to mention the entire Jedi order — telekinetic powers occupy a special place in the human cultural lexicon. Could humans eventually evolve abilities like Eleven? What is telekinesis, exactly? Do documented cases already exist? What role does technology play in these possible next stages of human evolution?
