Friday Essentials: 8 Unsolved Mysteries Science Cannot Answer

Understanding the mysteries of the universe around us is like an uphill challenge. We have been able to solve many such mysteries like rotation and revolution of planets, gravitational forces, the color of sky and many more.

The last few centuries have been pretty good for science. In 17th Century, Isaac Newton gave the 3 laws of motion. In 18th century, Ben Franklin introduced us to the electricity. In 19th century, Darwin explained the diversity of species. In 20th century, Einstein figured all stuff related to gravity. But there are still lots of mysteries left for the 21st century to solve in just a matter of 86 years.

But amidst these groundbreaking discoveries we often forget that our world is formed by all sorts of unseen forces that we don’t fully understand. With that being said, let’s look at some of the unsolved mysteries in this article that plague even the brightest of minds. Let’s delve into a world of mysterious questions varying that could change your very understanding about the universe.

  1. How did Life Originate?


Though this question doesn’t seem to be so hard to answer but it continues to defy all the solutions suggested by great scientists in the debates. The origin of life or the creation of Universe has always been a debatable subject of study since the Recorded History.

Some scientists relate the origin to the Big Bang Model where as much study has also been done on Abiogenesis, the ability of life to come from inorganic matter. Additionally, other scientists question whether Life spawn just once, or is it possible that it was created, wiped out, and then restarted?

  1. Why do we sleep?


We all know human body is regulated by a Circadian Clock which controls the Sleep/Wake Cycle. But the question is why do we sleep?

We spend nearly one-third of our lives snoozing and as per scientists our body tissues perform all the repair and maintenance activities. But then there are animals which do not sleep at all and scientists say they have different ways to rest and regenerate, then why do we need to sleep?

  1. What’s at the Heart of Black Hole?


Black Holes are considered as the Massive Monsters – violent, vastly destructive and invisible. Black Hole s, the most celebrated objects of astrophysics are described as the regions of space-time with such strong gravitational fields that even light cannot escape.

The real mystery is what at the center of Black Hole. The debate on what happens to the information or particles or objects that enter the black holes. All kinds of particles and radiations are absorbed by the black holes and Hawking radiations are emitted from it. But the hawking radiation doesn’t seem to have any information about what occurs inside the Black hole.

Some physicists thought that there might be a “singularity” – a point of infinite density with some mass concentrated down into an infinitely small space.

  1. Why is there more Matter than Antimatter?


This simple question raises a big question on the existence of everything in this universe. A great fact about the universe is “For every particle, there is an equal and opposite particle called an antiparticle”. So, for electrons, there are positrons. For protons, there are antiprotons. And so on.

According to our current understanding of particle physics, if any particle touches its anti particle, they annihilate and turn into radiation. We should be thankful that humans don’t get annihilated and hence it proves that antimatter is incredibly rare.

There is a lot of discrepancy between the ratios of the two types of substances matter and antimatter. The theories say that there were supposed to be an equal amount of both ordinary matter and antimatter (particles with same mass but opposite charge) in early universe. But the universe now is overwhelmed with regular matter.

  1. Why can’t we imagine Four Dimensions?


As humans, we find it difficult to envision the world with four spatial dimensions. But many physicists believe more dimensions in the space than the ordinary 3 needed for the physics to make sense of the universe. And if we cannot realize the fourth dimension than it consequently question the correctness of the String Theory which can only work in a universe with 10 or 11 dimensions. These dimensions comprise of 3 large spatial dimensions, 6 or 7 compacted spatial ones, and a time dimension.

  1. Are there parallel universes?

There is theory called as Multiverse which suggest that the cosmos contains multiple universes. In fact, some scientists believe that there are an infinite number of universes; which means an infinite number of civilizations, histories, and versions of you.

The astrophysical data suggests that space-time might be a flat rather than curved, and hence the region we can see is just one patch in an infinitely large “Quilted Multiverse”.

  1. Why is there an arrow of time?

Time is an onward march, we only get older, not younger. Trees only get taller; they don’t return to acorns. The universe has a property named as entropy because of which the time only moves forward. Entropy is roughly defined as the level of disorder which only increases and so there is no way to reverse a rise in entropy after it has occurred. The logic behind the increase in entropy is that if the disordered arrangements of particles outnumber the ordered arrangements, then the things change and they tend to fall into disarray.

The bigger underlying question in this question is why was entropy so low in past or we can say why was the universe so ordered at its beginning?

  1. Can anything travel faster than the Speed of Light?


The famous relativity theory of Einstein has changed the face of physics completely, and made it sure that nothing can travel faster than the speed of light. Though the studies on the speed of light have not fully disproved the theory that it is the fastest we can travel, but there is an increasing evidence that it might not be accurate.

Some point out that if the Big Bang Theory is correct, the universe expanded way quicker than the speed of light. Some scientists have performed carefully controlled experiments in which they have managed to clock pulses faster than the light pulses.
