Cattle Mutilation

For decades, there have been case reports by farmers who found mysteriously dead cattle with strange, surgically precise wounds. Strangely, these corpses were split open and most of their soft organs (e.g. eyes, tongues, intestine, genitals) had been removed. Even stranger, the corpses were completely drained of blood.

The mysterious, mutilated cattle corpses set off a diverse range of conspiracies of what could have caused such a bizarre phenomena. The most popular theories included: alien experimentation (explaining the surgical precision and lack of blood and organs), sacrifice by cults, vampires and the El Chupacabra (a mythological vampiric beast).

Cattle mutilation became so well-known that during the 70’s, it was properly investigated by the FBI. Of course, no evidence was found of aliens and vampires. As with most supernatural phenomena, cattle mutilation could be logically explained by science.

It was found that the cattle had simply died of natural causes, with no foul play involved (other than the occasional psychopaths attacking cattle). But how could natural death cause the surgical wounds, the missing organs and lack of blood? The answer is obvious when one thinks of what happens to animals after they die.

Scavengers such as foxes and buzzards often feast on decomposing corpses, cleanly removing the soft organs before they rot away (organs are the first to spoil). As scavengers usually bite into the corpses, this does not explain the clean wounds. This phenomena is due to insects also feasting on the corpse – a key part in putrefaction. Insects prefer softer tissue such as organs and ragged wounds, so after the insects are finished, wounds often look extremely clean. Also, putrefaction of tissue leads to massive gas production, causing bloating. Once this reaches a peak, the cattle corpse bursts like a balloon, causing clean tears in the abdomen. Lastly, the flies that were involved in cleaning away organs lay eggs, which hatch into maggots. Maggots immediately eat away the dead flesh and organs, even sucking up the blood that pooled at the bottom of the corpse. All of these factors combined results in what appears to be a mysterious alien bovine autopsy.

Although this may sound crazier than Chupacabras, the theory was actually tested in 1979 by a sheriff who kept receiving complaints about cattle mutilation. He took a dead cow, left it on a field and filmed it for 48 hours. The video clearly showed each step described above, proving that cattle mutilation was simply Mother Nature’s cruel, vicious way of returning a corpse back to the soil.

Sleep Paralysis

Sometimes just before you fall asleep, or just after you wake up, it is impossible to move any muscles. The panic caused by this sudden paralysis is soon followed by a sense of impending doom and unknown horror. When trying to look around to figure out what is happening, you see a ghost or demon sitting on your chest, pinning you down.
This is a typical scenario of sleep paralysis. It occurs when the mind wakes up before the body (in loose terms) and is experienced by everyone at least once throughout their life. 

Sleep is divided into two phases: REM (rapid eye movement) sleep and non-REM sleep. These two phases cycle to make up sleep at a 1:3 ratio (i.e. about 90 minutes non-REM, 30 minutes REM, repeat). NREM sleep is often thought of as “shallow sleep”, but this is incorrect as the third phase of NREM is literally “deep sleep”. This is followed by REM sleep, characterised by relaxation of muscle tone and the eyes darting in all directions (rapid eye movements). The brain cuts off motor signals to the body during REM sleep to prevent it acting out the movements in a dream (without this, many people would injure themselves or others during sleep). For example, patients suffering from diseases such as Parkinson’s disease with REM sleep disorder show vigorous movements during sleep, often hitting their partners in the process.

The problem occurs when the onset of REM atonia (relaxation) comes before the person fully falls asleep, or fails to disappear after waking up. As the motor system has been shut down, the muscles cannot be moved yet the person has regained consciousness. The more frightening thing is that sleep paralysis is usually accompanied by an intense visual and auditory hallucination, which is almost always related the person’s worst nightmares and fears. This explains why so many cultures associate it with demons and ghosts, and it is also possibly the cause of alien abduction experiences and ghost sightings. Reason being, the hallucination is so vivid the person easily believes that it actually happened.

Sleep paralysis can be caused by excessive drinking, stress or the induction of lucid dreams, but tend to be spontaneous and can happen to you on any day.

Star Wars

Star Wars is packed to the brim with epic scenes of starship dogfights. The many “pewpews” of laser cannons and massive explosions characterise this classic science fiction film series. However, this is an example of a classic “unscientific fiction”.

The great explosions of ships would never generate a loud sound as in space, there is no air or any medium to carry the sound waves. As the tagline for the movie Alien states: nobody can hear you scream in space.
In this regard, 2001: A Space Odyssey is most accurate in its portrayal of space. Not only does it have absolute silence during its scenes outside in space, but it also has accurate portrayals of space-science such as magnetic boots and rotating toilets to generate gravity.
