Is telekinesis real? - Emma Bryce

  • 0:07 - 0:09
    When the infamous fictional character,
  • 0:09 - 0:13
    Carrie White, left her high school
    prom hall ablaze,
  • 0:13 - 0:15
    and brought terror upon her town,
  • 0:15 - 0:19
    she relied on her powers of telekinesis,
  • 0:19 - 0:25
    the ability to manipulate physical
    objects using the power of the mind alone.
  • 0:25 - 0:29
    But while Carrie is just a fictional film
    based upon a fictional book,
  • 0:29 - 0:33
    belief in telekinesis
    isn't fictional at all.
  • 0:33 - 0:37
    For centuries, humans have claimed
    they really do have the power
  • 0:37 - 0:41
    to control the motion of objects
    using only their minds.
  • 0:41 - 0:45
    Levitation, opening doors at will
    and spoon bending
  • 0:45 - 0:47
    are all intriguing examples.
  • 0:47 - 0:51
    It happens in the Matrix when Neo
    freezes bullets midair,
  • 0:51 - 0:54
    and it's a skill that
    Yoda has honed to a T.
  • 0:54 - 0:56
    But is telekinesis real,
  • 0:56 - 1:01
    or just as fictional as
    Carrie, Yoda and Neo combined?
  • 1:01 - 1:04
    To investigate, we need to evaluate
    telekinetic claims
  • 1:04 - 1:08
    through a scientific lens
    using the scientific method.
  • 1:08 - 1:12
    Telekinesis is part of the discipline
    called parapsychology,
  • 1:12 - 1:15
    in which researchers study
    psychic phenomena.
  • 1:15 - 1:19
    Parapsychologists regard what they
    do as a science,
  • 1:19 - 1:21
    but other scientists disagree.
  • 1:21 - 1:23
    Let's start with a few basic observations.
  • 1:23 - 1:25
    Observation #1:
  • 1:25 - 1:29
    While there are loads of anecdotes out
    there about telekinesis,
  • 1:29 - 1:32
    there's no scientific proof
    that it exists;
  • 1:32 - 1:34
    no studies conducted according to
    the scientific method
  • 1:34 - 1:39
    and repeated under lab conditions
    can show that its real.
  • 1:39 - 1:44
    In the 1930s, the so-called father
    of parapsychology, Joseph Banks Rhine,
  • 1:44 - 1:47
    tested in the lab whether people
    could use telekinesis
  • 1:47 - 1:50
    to make a dice roll the way
    they wanted it to.
  • 1:50 - 1:54
    But afterwards, scientists couldn't
    replicate his results,
  • 1:54 - 1:56
    and since replication is key
    to proving an idea,
  • 1:56 - 1:58
    that was a problem.
  • 1:58 - 2:00
    Aside from scientists,
  • 2:00 - 2:03
    there are also countless
    self-proclaimed telekinetics,
  • 2:03 - 2:06
    but all have been exposed as tricksters,
  • 2:06 - 2:10
    or can't perform under conditions
    where they're not totally in control,
  • 2:10 - 2:15
    suggesting that they manipulate the
    situation to get the results they want.
  • 2:15 - 2:21
    Today, there's even a huge stash of prize
    money available from lots of organizations
  • 2:21 - 2:26
    for anyone who can prove that psychic
    abilities, like telekinesis, are real.
  • 2:26 - 2:29
    But these riches remain unclaimed.
  • 2:29 - 2:31
    Observation #2:
  • 2:31 - 2:32
    When we investigate telekinesis,
  • 2:32 - 2:37
    there's no consensus about
    what exactly is being measured.
  • 2:37 - 2:40
    Are powerful, Yoda-like brainwaves
    at work perhaps?
  • 2:40 - 2:44
    Since nobody agrees, it's difficult
    to apply a research standard,
  • 2:44 - 2:47
    something required in all
    other types of science
  • 2:47 - 2:49
    to test the validity of ideas.
  • 2:49 - 2:51
    Observation #3:
  • 2:51 - 2:54
    The point of science is to
    discover the unknown,
  • 2:54 - 2:56
    and in the history of
    scientific investigation,
  • 2:56 - 2:58
    it's definitely happened
  • 2:58 - 3:01
    that new discoveries have
    gone against established science,
  • 3:01 - 3:04
    and even overturned
    whole branches of science.
  • 3:04 - 3:08
    Such discoveries must be
    proven extra carefully
  • 3:08 - 3:10
    to withstand skepticism.
  • 3:10 - 3:12
    In the case of telekinesis,
  • 3:12 - 3:14
    the idea goes against established science,
  • 3:14 - 3:17
    but lacks the powerful
    evidence in favor of it.
  • 3:17 - 3:21
    Our universe is controlled
    and explained by the laws of physics,
  • 3:21 - 3:25
    and one of these laws tells us
    that brain waves can't control objects
  • 3:25 - 3:28
    because they're neither strong
    nor far-reaching enough
  • 3:28 - 3:32
    to influence anything
    outside of our skulls.
  • 3:32 - 3:36
    Physics also tells us that the only forces
    that can influence objects from afar
  • 3:36 - 3:39
    are magnetic and gravitational.
  • 3:39 - 3:43
    Probably the closest thing to
    telekinesis that science can explain
  • 3:43 - 3:47
    is the use of thoughts
    to control a robotic arm.
  • 3:47 - 3:50
    In the brains of stroke
    patients who can't move,
  • 3:50 - 3:54
    researchers can implant tiny wires
    into the region that controls movement,
  • 3:54 - 3:58
    and then train the patient to
    concentrate on moving a robotic arm,
  • 3:58 - 4:02
    which acts like an extension
    of their minds, and it works.
  • 4:02 - 4:04
    It's amazing, but it isn't telekinesis.
  • 4:04 - 4:08
    The patients thoughts aren't just vague,
    undetectable things.
  • 4:08 - 4:10
    They're measurable brain signals,
  • 4:10 - 4:13
    translated through wires into a robot.
  • 4:13 - 4:16
    Science can measure, test
    and explain the motion,
  • 4:16 - 4:20
    and that's how we've shown that
    this kind of mind control is real.
  • 4:20 - 4:23
    Science is a slow process of accumulating
  • 4:23 - 4:27
    the evidence that either stands
    for or against an idea.
  • 4:27 - 4:29
    When we stack up evidence,
  • 4:29 - 4:31
    we can see which tower grows tallest,
  • 4:31 - 4:36
    and in the case of telekinesis,
    it's not the tower showing that it exists.
  • 4:36 - 4:40
    Some say this mystical phenomenon
    can't fit within the confines of science,
  • 4:40 - 4:41
    and that's okay.
  • 4:41 - 4:45
    But then telekinesis becomes purely
    a matter of personal conviction.
  • 4:45 - 4:48
    If something can't be
    assessed scientifically,
  • 4:48 - 4:51
    then it can't be described
    as scientific either.
  • 4:51 - 4:53
    So the results of our investigation
  • 4:53 - 4:56
    reveal that however much
    we may want to believe
  • 4:56 - 4:58
    that the force really is within us,
  • 4:58 - 5:01
    the case for telekinesis
    remains weak.
  • 5:01 - 5:03
    Sorry Neo, Carrie and Yoda.
  • 5:03 - 5:07
    Your skills are mind-blowing,
    but for now, they belong in the movies.
