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.
There are well-defined regimes of physical phenomena where we do know how things work, full stop. The place to look for new and surprising phenomena is outside those regimes.
Our knowledge of the laws of physics rules them out. Speculations to the contrary are not the provenance of bold visionaries, they are the dreams of crackpots. A similar line of reasoning would apply to telepathy or other parapsychological phenomena. To believe otherwise, you would have to imagine that individual electrons obey different laws of physics because they are located in a human brain , rather than in a block of granite.
If parapsychologists followed the methodology of scientific inquiry, they would look what we know about the laws of physics, realize that their purported subject of study had already been ruled out, and within thirty seconds would declare themselves finished. Anything else is pseudoscience, just as surely as contemporary investigation into astrology, phrenology, or Ptolemaic cosmology. Science is defined by its methods, but it also gets results; and to ignore those results is to violate those methods.
Admittedly, however, it is true that anything is possible, since science never proves anything. Given the above, I would put the probability that some sort of parapsychological phenomenon will turn out to be real at something substantially less than a billion to one. We can compare this to the well-established success of particle physics and quantum field theory. The total budget for high-energy physics worldwide is probably a few billion dollars per year.
So I would be very happy to support research into parapsychology at the level of a few dollars per year. Never let it be said that I am anything other than open-minded. Register or Log In.

As the public slowly grew wise to the faked psychokinesis, the phenomenon faded from view. It was revived again in the s and s, when a researcher at Duke University named J.
Rhine became interested in the idea that people could affect the outcome of random events using their minds. Rhine began with tests of dice rolls, asking subjects to influence the outcome through the power of their minds. Though his results were mixed and the effects were small, they were enough to convince him that there was something mysterious going on.
Unfortunately for Rhine, other researchers failed to duplicate his findings, and many errors were found in his methods.
In the s, Uri Geller became the world's best-known psychic and made millions traveling the world demonstrating his claimed psychokinetic abilities, including starting broken watches and bending spoons.
Though he denied using magic tricks, many skeptical researchers observed that all of Geller's amazing feats could be — and have been — duplicated by magicians. 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.
What role does technology play in these possible next stages of human evolution? Read on — or use your telekinetic abilities to instantly download the article into your brain. Either way works, but if you choose the latter, do us all a favor and take some detailed notes on how you did it, OK? What is telekinesis?
Strength often varies from user to user depending on the origin of their powers, training, age, and so on. The caveat? For its part, the Flayer looked on from its Upside Down domain, watching the Snow Ball dance and keeping an eye on those meddlesome kids. No conclusive evidence was ever found to support telekinetic abilities. Again, these efforts have been unsuccessful.
So maybe moving objects with our minds is out of reach right now — but what about in the future? Could the next stages of human evolution include PK abilities? From a purely biological standpoint, probably not. As noted by Psychology Today , technology could help bridge the gap between mind and matter by leveraging brain-computer interfaces BCIs to allow direct control over computers and other connected devices without the need for tactile or voice interaction.
Mind-meld emails might seem unimpressive but could pave the way for a brave new world of telekinetic powers.
