Top 10 Confirmed Hypotheses Regarding The Cosmos

1 2

While Douglas Adams may have told us that 42 is the meaning of life, he did not provide the question everyone forgot, nor did it reveal all mysteries of the universe. Nonetheless, the scientific and technological advancements will always help mankind develop more complex hypotheses regarding the cosmos.

In spite of the plausibility some of these theories have today, they all started out the same, as crazy notions taken out of a science-fiction novel. Before we present the hypothesis, it is necessary to mention that science does not consider anything 100% certain and hence, there is always a new element that can be discovered to further confirm or disapprove a theory.

 

1. Big Bang

Perhaps the biggest question of them all implies the birth of the universe and how everything came to be. Granted, nobody can state for certain how all this started. However, considering that science found evidence of an ever-expanding universe, the big bang theory seems like a valid hypothesis. Essentially, because it is assumed the cosmos is constantly growing, research suggests that at one point everything was very close together and the expansion was the result of a collision effect.

 

2. The heliocentrism of the solar system

The discovery of the heliocentrism of the solar system was made in an age when the church reigned supreme. By constantly observing the sky, Nicolas Copernicus and afterwards, Galileo Galilei concluded that the Earth is revolving around the Sun and not vice versa as claimed by the Catholic Church. Unfortunately, the world was not ready to give up the church’s geocentric vision in their time. The theory only became a widely accepted notion in the 18th century.

 

3. The existence of black holes

The concept of black holes has been circulating since 1783 and the existence of these phenomena seemed very logical and plausible at the time. However, the reality of a celestial object that is so dense and has such an extraordinary gravitational pull that nothing can escape it was accepted much later after extended astronomic observation. Nowadays, black holes constitute an uncontested reality even though their functionality and role in the universe are yet to be unraveled.

 

4. The universe is constantly expanding

The concept of an expanding universe is nowadays supported by two scientifically proven theories. The first one is Hubble’s Law, a hypothesis that earned its validity via the observation that the object moving away from the Earth appears in the red part of the electromagnetic spectrum. The problem with this theory is that it raised an important question regarding the size of the universe. Even though the dimensions are currently unknown, scientists accept the idea of the Cosmological Constant (suggesting the cosmos has fixed dimensions) proposed by Albert Einstein.

 

5. Atoms

In spite of the fact that the atom theory is currently the cornerstone of scientific research, the “crazy” notion took centuries before it could gain acceptance. In a way, it is understandable considering that Leucippus and Democritus viewed the atom as the smallest particle that stood at the base of all building blocks and therefore, was invisible to the naked eye. In addition to being invisible, ancient people found it hard to dismiss the fact that everything is constructed from the basic four elements (water, fire, wind and earth).
