There are numerous mysterious phenomena on this planet, and some the researchers can explain while some they can’t. These surprising mysteries that are unexplained range from lost civilisations, to astronomical facts to animals and nature. There is no end to the vastness of this planet and so are the never-ending and intriguing mysteries. Here are 11 of the most surprising ones that apparently even science can not answer.
1. How Do Cats Purr?
Cats apparently purr when they feel happy. They are claimed to make vibrations through their vocal chords that releases pain and relieves stress. You can’t hear their heart beating when they purr and no one knows why.
2. Where Did Some Creatures Come From?
Many species don’t have their ancestral origin, for example the first land animals had well-developed limbs and heads, and no one knows how amphibians evolved from fish.
3. Do Cows Have A Magnetic Compass?
Scientists studied about a weird fact that 70% of cows turn their heads to the north or south while eating or drinking, which is observed everywhere, in all the continents no matter what terrain and weather it is.
4. What Was The “Gelatinous” Rain?
In August 1994, in Oakville, Washington, a weird phenomena occurred where instead of rain, jelly-like substances fell from the sky, and the other day dozens of people got symptoms similar to flu. Upon research, it was apparently found that the substance contained two types of bacteria, one of which is usually found in the human digestive system, however, this is still unexplained.
5. What Is Dark Matter?
Apparently the dark matter consists of 27% of the universe and it does not emit or interact with electromagnetic radiation, so it’s impossible to detect it. First theories came 60 years ago, but it is still unexplained.
6. How Many Planets Are In The Solar System?
Pluto was excluded as an official planet, Kuiper belt beyond Pluto consists of icy objects some even bigger than Pluto. Also, the researchers claim that some unknown planet as big as Earth pulled all the stones from the belt to itself.
7. Why Are People Right-Handed And Left-Handed?
About 70% to 95% people are right handed while 5% to 30% are left handed, but there are no genes for left handed people, identified. When a left handed kid is taught to write with right hand, he or she becomes a right handed. Along with genes, social environments are also an influence.
8. Why Did Megafauna Become Extinct?
Some believe that the megafauna, the giant animals that got extinct about 10000 years ago, got killed because of climate change or starvation, however there is no solid evidence.
9. Why Do We Dream?
Some claim that dreams are random images while some say they are subconscious desires, unsolved problems, and experiences. Study of dreams is known as oneirology.
10. What Is The “Space Roar”?
In 2006, scientists heard mysterious roars that apparently didn’t belong to stars or known cosmic phenomena. Sound waves can’t travel through space but radio waves can. No one knows where it came from.
11. Why Do We Have Different Blood Types?
Blood types have different antigens that are signals of antibodies to destroy foreign cells in the body, but no one has an answer why there are different antigens. Some say it might be related to immunity and diseases.
