Skeptics
often like to debunk alleged paranormal phenomena by saying, “That
can't have happened, because it would be a violation of the laws of
nature.” But how valid is such reasoning? Let's consider: what type
of phenomena would or would not be a violation of the laws of nature?
As we will see, the number of things that are clearly prohibited by
the laws of nature is much smaller than one might at first think. In
this post I will not try to persuade you that any of the phenomena I discuss is
likely. I will merely discuss whether any of them is ruled out or excluded
by the laws of nature.
Something
That Occurs For a Completely Unknown Reason
Skeptics
sometimes evoke the law of causality (the law that everything has a
cause) when trying to exclude a wide range of phenomena. The
reasoning goes like this: we don't understand what could have caused
alleged phenomenon x, so we should not believe that phenomenon
x occurred, because it would be a violation of the law of
causality.
But
this reasoning is fallacious. The fact that we have no understanding
of the cause for a particular phenomenon does not mean that it did
not have a cause. It is entirely possible that there are 1001 types
of causes we do not understand because of our ignorance. In short,
we can't really exclude any paranormal event on the basis of it being
a violation of the law of causality, because there might always be
some unknown possible cause.
Something
That Suddenly Disappears
I
do not know of anyone alleging a case of an object suddenly
disappearing, although such disappearances are often parts of magic
acts. Let's consider whether such an event would violate the laws of
nature. There is a law of nature called the law of the conservation
of mass and energy. This law holds that while matter can be converted
to energy, and energy can be converted to matter, it is impossible to
either create or destroy mass-energy. From the perspective of this
law, a piece of matter cannot simply disappear, but it can be
converted to energy. However, the formula for this conversion is
Einstein's famous equation E = mc2 . This means that
converting even a very tiny piece of matter to energy would produce a
gigantic amount of energy, greater than the energy of a H-bomb.
This
might seem to suggest that it would be a violation of the laws of
nature for an object to suddenly disappear, unless there was a
gigantic release of energy at the same time. But this isn't
necessarily so, because of some loopholes. For one thing, some
paranormal process might have some strange ability to soak up the
energy produced by the conversion of a piece of matter to energy.
Secondly, when a piece of matter disappears it might simply be
converted to a different form of matter. For example, a process might
convert the atoms of a piece of solid matter into subatomic
particles, which might dissipate into the air. Third, the matter in a
disappearing object might pass through a space-time wormhole, and end
up someplace else. Fourth, the matter in an object that disappears
might simply be condensed. Since atoms are almost entirely empty
space, some process might shrink those atoms to become matter too
dense to be seen. In short, the sudden disappearance of something
(without a huge explosion at the same time) would not necessarily
violate any laws of nature.
Something
That Suddenly Appears
The
sudden appearance of small objects has been alleged by certain
mediums, who claim that objects can sometimes appear as a result of
communication with the dead. From the standpoint of the law of the
conservation of mass and energy, the matter for a new object could be
produced from energy, but a huge amount of energy would be needed.
But there would be a simpler way to get the matter to make an object
suddenly appear: just get it from the air. In theory, some
paranormal process or technological process could grab as many
protons, electrons, and neutrons as it needed from the ordinary air,
and convert those subatomic particles into some material object. No
one might notice the missing air, as other air in the atmosphere
would move in instantly to fill the gap. So it would not seem to
violate any laws of nature for a small object to suddenly appear
somewhere. Another possibility is that the object might be prepared
at some other location, and then transported through a space-time
wormhole. After traveling through the wormhole, the object might seem
to suddenly appear at a particular location.
Levitation
Levitation
has been alleged to occur in certain seances, and certain Eastern
mystics have claimed to have had a power of levitation. In the 19th
century numerous reputable witnesses claimed to have seen Daniel
Dunglas Home levitate heavily weighted tables and himself.
D. D. Home, called the most interesting man in the world
Regardless
of whether such claims are credible, levitation seems to involve no
violation of the laws of nature. A naïve view is that levitation
would violate the law of gravitation, but that isn't so. In order for
something to levitate, you merely need some force underneath the
object that equals the very weak gravitational force tending to keep
the object on the ground. Such a force might be produced by any
number of factors, normal or paranormal. The amount of energy needed
for levitation of a person or table is almost trivial.
Sudden
Physical Transformations
A
literary example of a sudden physical transformation is the
scriptural story of the changing of water into wine. Another example
(just to imagine something randomly) is the changing of a rock into
an apple. Are such things prohibited by the laws of nature? No. If
such things were to occur, they would be just kind of rapid molecular
reconfigurations, a rearrangement of atoms within some unit of space.
Such a rearrangement would merely require some highly sophisticated
power or technology. We can, for example, expect that super-advanced
alien technologies might be able to do things such as quickly change
rocks into apples, by using a very advanced molecular rearrangement
technology.
Telepathy
Precognition
“Miraculous”
Cures
Some
people claim that there are cases of very sick people who were
suddenly cured in a way that cannot be accounted for. Would such a
thing violate the laws of nature? No, it wouldn't. All alleged cases
of miraculous cures can be classified as cases of molecular and
atomic rearrangement, and as mentioned before, such rearrangement is
not prohibited by the laws of nature. Any sufficiently advanced
technology could achieve such rearrangements.
Life
After Death
One
popular idea about life after death is that there is some kind of
soul that lives on after death. According to this thinking, life
after death can be imagined as a kind of information preservation,
state preservation, or partial state continuity. There is nothing in
the laws of nature that prohibit such a thing. Another popular idea
is the idea of the mass physical resurrection of the dead at some day of
judgment. This idea seems to be declining in popularity, but it is
not prohibited by the laws of nature. If one considers a particular
person to simply be an arrangement of atoms, then a mass resurrection
of the dead can be considered as simply a large-scale case of atomic
or molecular rearrangement – rearranging randomly available atoms
and molecules to match a previously existing arrangement of atoms.
Such a possibility may be highly improbable, but is not clearly
prohibited by the laws of nature.
The
“What If Aliens Could Do It?” Thought Experiment
The
next time you are tempted to exclude some alleged phenomenon on the
basis of “that's impossible,” try this thought experiment.
Imagine that our planet receives visitors from some gigantic
extraterrestrial spaceship, and the visitors claim to be millions of
years more advanced than us. Suppose the visitors then claim that
they can do whatever paranormal thing you have ruled out as an
impossibility. Would you then believe that such a thing is possible?
If so, then you probably have no business ruling out such a
possibility now on the basis of impossibility.
What
Type of Phenomena Would Violate the Laws of Nature?
After
considering all these cases of possible unusual phenomena that would
not violate the laws of nature, I need to balance things by
considering some possibilities that would violate the laws of
nature. I can think of a few.
It
would violate a law of nature for a very gigantic mass of particles to
drift around in a particular small area of outer space without ever contracting into
a denser state. That would violate the law of gravity.
It
would violate a law of nature for a very large positive charge to
exist in outer space for a long time 1 millimeter away from another
very large positive charge, without the two ever flying apart from
each other. That would violate a law of electromagnetism called
Coulomb's law.
It
would violate a law of nature for an asteroid hurtling between
Jupiter and Mars to suddenly stop in space, without any force acting on it to stop its motion. That would violate Newton's first
law of motion.
It
would violate a law of nature if I sent out a radio signal from
Earth, and it was instantly received by a radio receiver on Mars.
That would violate a law that electromagnetic radiation cannot travel
faster than the speed of light.
It
would violate a law of nature if two cannons pointed at each fired
iron cannon balls at each other, the balls collided at very high
speed, and then simply fell directly to the ground, both resting next
to each other (but unattached) at a spot below the point of
collision. That would violate Newton's third law of motion.
So
there are actually things we can imagine that would violate the laws
of nature. But examples such as these are very different from the
type of things one reads about in books about alleged paranormal
phenomena. The laws of nature are almost never rules involving
impossibility. The most fundamental laws of nature are most commonly
“whenever” type of rules, rules such as “whenever x
occurs, force y shall occur.”
In
short, regardless of the credibility of claims of the paranormal, it
seems that the laws of nature actually leave the door wide open to
the possibility of such phenomena.
