Most of us have this thought in mind that science can prove everything using evidence and facts. Science has surely pushed our understanding of this living world, but there are still some questions that haven’t been answered. Here are 10 interesting ones I’d like to share with you all:
1) Cows will ALWAYS face north or south while grazing
Most people certainly do not realize this but there is something peculiar about how cows graze. According to a group of scientists that examined satellite images of cows on Google Earth, cows ALWAYS stand alongside the magnetic poles of Earth by facing either north or south. Pretty cool, isn’t it? And this didn’t only happen in one place, but across six different continents! Moreover, this pattern remains consistent regardless of any environmental related factors like wind flow or rainfall. What really intrigues me is the fact that scientists have literally no clue about whether this phenomenon has a correlation to navigation or is some sort of a technique to ward off their predators. So if you ever encounter cows grazing, do take a look at what direction they are facing to.
Most scientists comprehend the functioning of magnets to a certain degree but what they don’t understand is why do natural magnets consistently have a north and south pole? This may be pretty strange but every time you cut a magnet into half, you’ll always end up with a magnet piece consisting of a north and south pole. Besides this factor, even if we look at magnets in general, what is the point of having them?
3) Stone Balls of Costa Rica
Stonehenge is a prodigious prehistoric monument situated in Wiltshire, England and is indisputably filled with a lot of mystery and virtues. What was it created for? Was it a spiritual or devout place? There is no genuine evidence to support this notion. On top of that, there is an enigma that has led to confusion between the locals of Costa Rica, though it doesn’t possess of the curbsides that are present in Stonehenge. They are known as giant stone balls. In the whole of Costa Rica, you’ll be able to discover balls in ranging sizes that can be as humongous as 8 feet! The uncanny fact about them is the way they’ve been crafted because they’re imperfectly perfect. It’s unfeasible for locals to construct them using their crude tools. This leaves us questioned about where they originated from and what exactly is the purpose of the balls.
4) Animals that can live without oxygen
We all know that nearly every living organism on this planet requires oxygen for their survival. Well, this may not be the case after oxygen-free animals were discovered in the deep coast of the Mediterranean Sea. Even though specific types of bacteria have the ability to survive without oxygen, it’s unusual to find the occurrence of this phenomenon in multi cellular species that are complex in nature. Nonetheless, research has shown that these organisms belong to a class called Loricifera phylum, that consists of miniature organisms that previously lived on oxygen. As oxygen levels dropped and salinity levels began to increase, these little organisms adapted themselves to the new environment and eventually learnt to live without oxygen.Scientists are unable to make any sense about this unforeseen happening and need more evidence to uncover the hidden realities of their evolutionary past.
5) Dark Energy
One of the most enigmatic mysteries of science would be dark energy. Although dark matter forms 80 percent of the total mass, it is assumed that dark energy makes up over 70 percent of the total content in the whole universe. But, what is it made of? Is dark energy continual or are there fluctuations all over the expanse of the galaxy? Why is the density of dark energy equal to that of regular matter? Science has no answer to such questions.
6) Mysterious moon of Saturn
In 2012, NASA’s Cassini got hold of Saturn’s rings and uncovered some sort of disturbance which caused them to believe that a little moon was forming on its surface. Astronomers called it Peggy. Surprisingly, NASA’s Jet Propulsion Lab officially declared that the object is expected to remain the same size or even fall apart. The current status of Peggy is unknown to scientists and the rest of the world.
7) Why does it take more genes to make a tomato than a human?
Tomatoes are composed of over 30,000 genes in comparison to us, human beings, who have genes between 20,000 and 30,000. This problem has co-existed in various semblances since the past few years and is known as the C-value paradox. However, in 2003, botanists announced that they’d be downgrading this issue to an “enigma”- and until now, it remains unexplained by science. Something like a tomato having more genes than us, sounds bizarre!
8) Why is the Sun’s atmosphere hotter than its surface?
Corona, which is the name for the Sun’s atmosphere, expands over a million kilometers from the surface of the Sun and is hypothesized to reach temperatures as high as two million degrees. In comparison to the mere 5000 degrees temperature of the Sun’s surface, this value is significantly high. There’s no explanation of this huge variation between the temperatures.
9) Sound in space
Eleven years ago in 2006, a few scientists were exploring the stars when they had an encounter with a noise that interrupted their research. They were unable to figure out the cause of the noise, especially when they’re aware of the fact that sound can’t travel through space. Assuming it to be radio waves, they were still confused about why it happens to be about six times “louder” than it’s required to be, which leaves us blank as no conclusion can be reached.
10) Dark streaks on the surface of Mars
Mars is now a planet humans have turned into a type of pop culture phenomenon for sustainable life outside of Earth. Studying more about Mars leaves us with more and more questions. For instance, scientists are trying to capture extensive dark-colored streaks on Mars’ surface which can only be visible during the summer time. Since water is not detected in those particular areas of the planet, we’re left with more doubts. What are these dark streaks used for? Why do they disappear during the cold season? We never know.
