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