Some natural phenomena we see around us every day are still completely mind-boggling. Every once in a while, a scientist will come forward with a new theory that claims to explain one of these phenomena; a theory that’s sometimes backed by years of research, and sometimes just comes from a person who’s looking to get famous in the scientific community. From gravity to the color of the sky, there are many things that make sense to some, but are a mystery to the vast majority of us. Here are just a few phenomena that science still can’t explain.
Why are black holes so difficult to understand?
The mystery of black holes has fascinated us for centuries. We know that they exist, and we have an idea of how they came to exist, but all we have are guesses and theories. Nobody knows what is inside a black hole, or how they truly came to exist. Some scientists believe they are the leftovers of stars that exploded, while others think they are the key to time travel. It is difficult to understand because they are so difficult to observe! Black holes are strange because they do not emit light, and surround themselves with a donut-shaped region of radiation that is also invisible to telescopes. The radiation has a temperature of over one trillion degrees, which is hotter than any place in the universe.
The weird things found in quantum entanglement
We have been able to harness the power of the atom for practical use, and build computers and other technology that can do amazing things. Yet as much as we have learned, there are still some aspects of quantum mechanics that seem to defy explanation. For example quantum entanglement suggests two quantum particles react to each other instantaneously regardless of distance. If you entangle two particles, their states are said to be linked, and they are connected even if they are very far apart. If one of the particles is changed, the other particle changes state instantly, even if they are on opposite sides of the universe. We have not yet been able to prove that this is real, but many prominent scientists believe that it is.
Why we can’t measure time
Time is arguably the most misunderstood phenomenon in physics. There are several popular but incorrect beliefs surrounding time. The first of these is that time is a physical entity. This is wrong because time cannot be observed. If a clock is broken, it is not time that is broken. Similarly, time cannot be measured. A standard hour, or even a standard minute, is just an arbitrary unit of time. It could be any interval of time, but it is convenient for us to use an hour or a minute as a unit of measurement. So, what is time anyway? We all know what it is — it’s that thing that keeps marching on, never stopping or pausing for a moment to rest.
How can you know if you are conscious?
Despite many advances in our understanding of the human brain, consciousness remains an elusive concept. The question of what consciousness is and how it works has puzzled philosophers and scientists for centuries. Researchers have proposed a variety of theories to explain how our physical brains can give rise to something as seemingly immaterial as consciousness, and while there is no universally accepted answer, there are some theories that have gained more traction than others. One of these is integrated information theory, which suggests that consciousness emerges from the interaction of several brain areas that process information in a highly coordinated manner.
