WEBVTT 00:00:07.250 --> 00:00:09.202 When the infamous fictional character, 00:00:09.202 --> 00:00:13.315 Carrie White, left her high school Prom hall ablaze, 00:00:13.315 --> 00:00:15.498 and brought terror upon her town, 00:00:15.498 --> 00:00:18.635 she relied on her powers of telekinesis, 00:00:18.635 --> 00:00:24.868 the ability to manipulate physical objects using the power of the mind alone. 00:00:24.868 --> 00:00:28.857 But while Carrie is just a fictional film based upon a fictional book, 00:00:28.857 --> 00:00:32.858 belief in telekinesis isn't fictional at all. 00:00:32.858 --> 00:00:36.529 For centuries, humans have claimed they really do have the power 00:00:36.529 --> 00:00:40.712 to control the motion of objects using only their minds. 00:00:40.712 --> 00:00:44.744 Levitation, opening doors at will and spoon bending 00:00:44.744 --> 00:00:47.237 are all intriguing examples. 00:00:47.237 --> 00:00:51.097 It happens in the Matrix when Neo freezes bullets midair, 00:00:51.097 --> 00:00:54.463 and its a skilled that Yoda has honed to a tee. 00:00:54.463 --> 00:00:56.125 But is telekinesis real, 00:00:56.125 --> 00:01:00.904 or just as fictional as Carrie, Yoda and Neo combined? 00:01:00.904 --> 00:01:04.304 To investigate, we need to evaluate telekinetic claims 00:01:04.304 --> 00:01:08.477 through a scientific lens using the scientific method. 00:01:08.477 --> 00:01:12.286 Telekinesis is part of the discipline called parapsychology, 00:01:12.286 --> 00:01:15.370 in which researchers study psychic phenomena. 00:01:15.370 --> 00:01:18.514 Parapsychologists regard what they do as a science, 00:01:18.514 --> 00:01:20.974 but other scientists disagree. 00:01:20.974 --> 00:01:23.461 Let's start with a few basic observations. 00:01:23.461 --> 00:01:25.282 Observation #1: 00:01:25.282 --> 00:01:28.620 While there are loads of anecdotes out there about telekinesis, 00:01:28.620 --> 00:01:31.569 there's no scientific proof that it exists. 00:01:31.569 --> 00:01:34.425 No studies conducted according to the scientific method, 00:01:34.425 --> 00:01:38.903 and repeated under lab conditions, can show that its real. 00:01:38.903 --> 00:01:43.871 In the 1930s, the so called father of parapsychology, Joseph Banks Rhine, 00:01:43.871 --> 00:01:47.169 tested in the lab whether people could use telekinesis 00:01:47.169 --> 00:01:50.474 to make a dice roll the way they wanted it to. 00:01:50.474 --> 00:01:53.708 But afterwards, scientists couldn't repliate his results, 00:01:53.708 --> 00:01:56.386 and scince replication is key to proving an idea, 00:01:56.386 --> 00:01:58.237 that was a problem. 00:01:58.237 --> 00:01:59.688 Aside from scientists, 00:01:59.688 --> 00:02:02.970 there are also countless self-proclaimed telekinetics, 00:02:02.970 --> 00:02:06.347 but all have been exposed as tricksters, 00:02:06.347 --> 00:02:10.492 or can't perform under conditions where they're not totally in control, 00:02:10.492 --> 00:02:15.256 suggesting that they manipulate the situation to get the results they want. 00:02:15.256 --> 00:02:20.681 Today, there's even a huge stash of prize money available from lots of organizations 00:02:20.681 --> 00:02:26.093 for anyone who can prove that psychic abilities, like telekinesis, are real. 00:02:26.093 --> 00:02:29.024 But these riches remain unclaimed. 00:02:29.024 --> 00:02:30.659 Observation #2: 00:02:30.659 --> 00:02:32.401 When we investigate telekinesis, 00:02:32.401 --> 00:02:36.541 there's no consensus about what exactly is being measured. 00:02:36.541 --> 00:02:40.026 Are powerful, Yoda-like brainwaves at work, perhaps? 00:02:40.026 --> 00:02:43.996 Since nobody agrees, its difficult to apply a research standard, 00:02:43.996 --> 00:02:46.759 something required in all other types of science 00:02:46.759 --> 00:02:49.401 to test the validity of ideas. 00:02:49.401 --> 00:02:50.921 Observation #3: 00:02:50.921 --> 00:02:54.025 The point of science is to discover the unknown, 00:02:54.025 --> 00:02:56.392 and in the history of scientific investigation, 00:02:56.392 --> 00:02:57.806 its definitely happened 00:02:57.806 --> 00:03:01.391 that new discoveries have gone against established science, 00:03:01.391 --> 00:03:04.414 and even overturned whole branches of science. 00:03:04.414 --> 00:03:07.668 Such discoveries must be proven extra carefully 00:03:07.668 --> 00:03:10.135 to withstand skepticism. 00:03:10.135 --> 00:03:11.717 In the case of telekinesis, 00:03:11.717 --> 00:03:14.270 the idea goes against established science, 00:03:14.270 --> 00:03:17.493 but lacks the powerful evidence in favor of it. 00:03:17.493 --> 00:03:21.130 Our Universe is controlled and explained by the laws of physics, 00:03:21.130 --> 00:03:25.305 and one of these laws tells us that brain waves can't control objects 00:03:25.305 --> 00:03:28.271 because they're neither strong, nor far reaching enough, 00:03:28.271 --> 00:03:31.795 to influence anything outside of our skulls. 00:03:31.795 --> 00:03:35.974 Physics also tells us that the only forces that can influence objects from afar 00:03:35.974 --> 00:03:39.356 are magnetic and gravitational. 00:03:39.356 --> 00:03:43.280 Probably the closest thing to telekinesis that science can explain 00:03:43.280 --> 00:03:47.405 is the use of thoughts to control a robotic arm. 00:03:47.405 --> 00:03:50.085 In the brains of stroke patients who can't move, 00:03:50.085 --> 00:03:54.414 researchers can implant tiny wires into the region that controls movement, 00:03:54.414 --> 00:03:58.396 and then train the patient to concentrate on moving a robotic arm, 00:03:58.396 --> 00:04:01.800 which acts like an extension of their minds, and it works. 00:04:01.800 --> 00:04:04.480 It's amazing, but it isn't telekinesis. 00:04:04.480 --> 00:04:07.783 The patients thoughts aren't just vague, undetectable things. 00:04:07.783 --> 00:04:09.607 They're measurable brain signals, 00:04:09.607 --> 00:04:12.972 translated through wires into a robot. 00:04:12.972 --> 00:04:16.123 Science can measure, test and explain the motion, 00:04:16.123 --> 00:04:19.566 and that's how we've shown that this kind of mind control is real. 00:04:19.566 --> 00:04:22.942 Science is a slow process of accumulating 00:04:22.942 --> 00:04:27.120 the evidence that either stands for or against an idea. 00:04:27.120 --> 00:04:28.836 When we stack up evidence, 00:04:28.836 --> 00:04:31.035 we can see which tower grows tallest, 00:04:31.035 --> 00:04:35.730 and in the case of telekinesis, its not the tower showing that it exists. 00:04:35.730 --> 00:04:39.858 Some say this mystical phenomenon can't fit within the confines of science, 00:04:39.858 --> 00:04:41.277 and that's okay. 00:04:41.277 --> 00:04:45.467 But then telekinesis becomes purely a matter of personal conviction. 00:04:45.467 --> 00:04:47.758 If something can be assessed scientifically, 00:04:47.758 --> 00:04:50.584 then it can't be described as scientific, either. 00:04:50.584 --> 00:04:52.560 So the results of our investigation 00:04:52.560 --> 00:04:55.713 reveal that however much we may want to believe 00:04:55.713 --> 00:04:57.943 that the force really is within us, 00:04:57.943 --> 00:05:00.922 the case for telekinesis remains weak. 00:05:00.922 --> 00:05:03.021 Sorry Neo, Carrie and Yoda. 00:05:03.021 --> 00:05:07.158 Your skills are mind-blowing, but for now, they belong in the movies.
