Scientific theories are often considered factual and accurate by people all over the world. These theories are always reconsidered and closely examined by various researchers. With the advances in modern research, old ideas, hoaxes, and myths are rejected by evident experiments. Here, our science dissertation writing experts, have analyzed a few scientific facts that were later proved wrong.
Theory of static universe
It was commonly believed that the size of the universe was constant. The idea stated that the total volume of the universe was fixed, and all the dimensions form a closed system. Later in 1917, Albert Einstein gave his theory of stationary universe where he argued in favor of it and also calculated his theory of general relativity according to this concept. But with Edwin Hubble’s discovery of the relationship between redshift and distance, researchers believed that the universe was expanding.
The theory of cold fusion
It usually requires an extremely high temperature to create the nuclear energy. However, the theory of cold fusion states that such a reaction is possible at room temperature. This theory got widely popular realizing that if a nuclear reaction could occur at room temperature, then an abundance of energy could be created without the dangerous wastes. But when other scientists tried to replicate the experiment, they failed to get similar results. The scientists who gave this theory were later accused to have stretched the truth of their findings.
The black state theory
This is one of the most controversial theories in psychological science that states, people are born with no built-in personality traits. However, it is now widely accepted that genes and other family traits inherited from birth also play a crucial role in trait development. Studies of adopted children and twins raised in separate families have illustrated that certain characteristics can exist from birth.
The theory of luminiferous aether
Aether, also known as the ether, was a mysterious substance earlier that was believed to be the medium through which light was transmitted through the universe. This idea of a luminiferous aether was debunked with experiments of the diffraction and refraction of light, and later the entire concept got revolutionized with Einstein’s special theory of relativity.
This theory states the idea that all combustible objects contain a special element called phlogiston that is released during burning, and the entire process of combustion is possible just because of this element. In its traditional form, phlogiston was supposed to have no color, taste, or odor, and was only made visible when a flammable object caught fire. Later as more experiments were performed using this model, it started turning into a dubious theory. The idea eventually fell out of favor and was replaced by more sophisticated theories, like oxidation.
Stress theory of ulcers
As peptic ulcers became very common in the 20th century, doctors stated stress to be the main reason behind it.Therefore, patients were medically adviced to take antacids and modify their lifestyle. In the 1980s, Australian clinical researcher Barry Marshal discovered that the ‘bacterium h pylori’caused peptic ulcer disease. And then this theory was revised, and medication was invented for the cause.
The theory of immovable continents
In the early 20th century, scientists believed the Earth’s continents were stable and did not move. This concept was challenged in 1912 with Alfred Wegener’s formulation of the continental drift theory, and his explanation of tectonic plates.
These were a few scientific hypothesis that was later proved wrong by researchers.
