Science helps us better understand ourselves and the world around us—everything from a molecular level to how our planetary systems work. Science is here to help bring forth answers to which we have questions, from curing deadly diseases to understanding how species have gone extinct. It has helped prove and disprove many theories over the decades and is continually evolving. The word, scientist, was first mentioned in 1834 after philosopher and historian William Whewell claimed it. Whewell used the word “scientist” to describe one who studies the natural and physical world’s organization and behaviour through observation and experiments.
With the help of our friend science, we all can take advantage of the beautiful technologies it throws at us, going from computers the size of rooms to computers you can hold in your hand. Now we can conveniently store this technology in our pockets, thanks to Moore’s law. Moore’s law observes that the number of transistors in a condensed circuit will double approximately every 18 months. This has held firm since 1965, ever since Gordon E. Moore, the founder of Fairchild Semiconductor and Intel, brought forth this notion. If we continue this trend with computers and now supercomputers, it won’t be long before it surpasses human intelligence. Will this lead us to a Terminator-based scenario? Could it help give more advanced solutions to make the world a better place?
Many famous scientists, such as Darwin, Einstein, Tesla, and Newton, have laid the groundwork to understand our Universe better. A lot of the work they accomplished remains relevant today. Although they didn’t get everything right, some ideas have been added onto their already existing platforms, and some things have since been disproven. Specific topics brought forth by these scientists, still to this day, have yet to explain as to why it is. Whether it be a new or older science-based head-scratcher, we will try and find the answer. After all, it’s human nature.
As we continue to advance rapidly, there are still plenty of science mysteries we can’t fully apprehend.
Here are some problems still trying to be understood…
What Causes Gravity?
Ever since Sir Isaac Newton observed an apple falling from a tree, he was left to think about the forces of nature and how they work. Many scientists, ever since, have been trying to understand what causes this phenomenon. Take Einstein’s theory of relativity, which only explains gravity on a grand scale, explaining why gravity tugs on the matter to form galaxies and stars. However, when you try to do calculations on smaller gravitational fields, the math doesn’t work out.
Gravity is the weakest of all powers in the Universe. Simultaneously, making it the most mysterious, as scientists can’t measure it in a lab setting. Yet, without gravity, we would not exist.
Why is there a limit to the Speed of Light?
Einstein’s special relativity gives us a theory that provides the speed of light at a rate of 186,000 miles per second. Einstein hypothesized that light frequently travels at the same pace for every person viewing it, regardless of how fast they travel. Currently, it is unknown why the speed of light is the speed at which it is. However, we do know without it, our Universe and we could not and would not exist.
What causes Out of Body Experiences (OBE)?
One in 10 people have an out-of-body experience (OBE) several times in their life.
Having an out-of-body experience involves the feeling of floating beyond one’s body. These astral projections can occur for numerous reasons, usually in a dream state, near-death experience, severe brain trauma, sensory deprivation, significant dehydration and or under the influence of psychedelic drugs.
In the fields of neuroscience and psychology, a lot of theories have appeared as to why OBEs occur. The most common being, an OBE, is an experience from an altered mental state, like in a dream. With recent advancements in technology, scientists can create an illusion of the patient having an OBE while using an MRI machine to see what brain parts are being triggered. However, even with these technological advancements, this theory is still far from any justification as to why this happens in the first place.
The Origin of Life
In the Darwinian world, evolution has taught us that our closest living ancestor is the chimpanzee. We are even closer concerning the more recently discovered – bonobo chimp from the Congo. Unlike the screeching screams and fighting in the chimpanzee world, where males are the leaders, laughter can be heard all day where bonobos play and look after one another, and females are the leaders in their clans.
But how and where did life come from in the first place?
Some scientists consider life appeared the moment our planet was healthy enough to support it. Leading estimates say Earth formed about 4.5 billion years ago. The earliest evidence for life on Earth is from fossilized bacteria, coming from a region in Australia that is approximately 3.4 billion years old. As old as they are, these bacteria’s biochemistry (which surprisingly are still around today) is so intricate that they have cell walls protecting their DNA, leading scientists to believe that life must have begun much earlier, maybe as far back as 3.8 billion years ago.
Just because they know rough estimates of when life first appeared, scientists are still far beyond answering how it got here.
The Placebo Effect
The placebo effect was first observed in the second world war. Henry Beecher first discovered this effect when he ran out of morphine to treat wounded soldiers. Instead, he gave them saline like a solution and found that 40 percent of people who received it were relieved of their pain.
Many experiments have since been conducted to try to understand why the placebo effect occurs. In his and many other studies, David Burns MD (creator of cognitive behaviour therapy) showed that a sugar pill was more effective than any anti-depressant or herbs are given to the patient for treatment of depression. Even when a patient knowingly was given a placebo, it still showed to have helped heal ailments.
Reasons why the placebo effect works is still a highly debated subject…
