Why is there something and not just nothing? This is the ultimate question of all questions.

The question of where the first life came from is one of the seven Welträtsel described by Emil du Bois-Reymond in 1880. Werner Ahrendt substantiates his assumption that the first forms of life originated on the seabed.

All living organisms on Earth use the same genetic code to translate genetic information into proteins. Werner Ahrendt presents a hypothesis as to how this code may have evolved over the course of natural history.

The stone rows of Carnac are a well-known tourist attraction in Brittany. But what was the primary purpose of this Stone Age monument?

How what we call consciousness arises in the brain is undoubtedly one of the world's great unsolved mysteries. Emil du Bois-Reymond posed this question in his famous lecture, "The Seven Mysteries of the World," given at the Berlin Academy of Sciences in 1880: "Where does conscious sensation come from in the unconscious nerves?"

Respiratory infections are most common during winter months. Why is this the case?

Problems can never be solved with the same mindset,
that created them.

Albert Einstein (1879 - 1955)

Over the past 500 years, the science of physics has limited itself to recording what happens in nature using measuring instruments and describing the relationships found using mathematical formulae. Today's physics can therefore answer neither the question of the nature of things nor the question of the genesis of physical

Human beings are capable of greater intellectual achievements than any other living creature on earth. How did this happen? The answer may shed some dark light on our ancestors.

What is "time"? This question not only moved the church father Augustine, but is still a fundamental question for our understanding of the world today.

The properties of elementary particles show regular patterns, especially in their electrical charges. How can these regularities be explained?

All elementary particles have a property called spin, which is interpreted as the intrinsic angular momentum of the particle. In classical mechanics, each angular momentum is associated with rotational energy. Is rotational energy also associated with the spin of elementary particles? If so, how big is it?

In the common narrative of the history of science, one finds the story that classical mechanics was replaced by Einstein's theory of relativity and is contained in the theory of relativity as a special case for small velocities. On closer inspection, however, this narrative is not quite right.

The principle of least action, also known as Hamilton's principle, is a fundamental principle of theoretical physics from which the laws of motion in many areas of physics can be derived. However, our current knowledge gives no indication as to why this principle is universally valid.
