The speed of light is roughly 186,282 miles per second, or 299,792,458 metres per second. It is the    universe's fastest speed now understood, and it is crucial to many scientific hypotheses.

2 James Watson and Francis Crick discovered DNA, the molecule that houses the genetic information  necessary for the growth and operation of every living thing, in 1953. Their finding completely changed biology.

3 The age of the universe is roughly 13.8 billion years. Based on observations of the universe's expansion and cosmic microwave background radiation, its age has been calculated.

4 The 86 billion neurons in the human brain give it its incredible complexity. Specialised cells called neurons use electrical and chemical impulses to relay information.

5 Charles Darwin first introduced the theory of evolution in 1859, and it describes how organisms change through time through a process known as natural selection. It is one of the scientific hypotheses that is most commonly accepted and serves as the basis for contemporary biology.

6 An atom is the smallest piece of stuff. Protons and neutrons make up the nucleus of an atom, which is encircled by electrons. The building blocks of all substances are molecules, which are made up of various atom combinations.

7 Dmitri Mendeleev organised all known elements into the periodic table of elements in 1869 based on their atomic number and chemical makeup. It is an essential instrument in chemistry and offers useful knowledge about how various elements behave.

8 The scientific theory of plate tectonics describes how the Earth's lithosphere, or solid outer shell, is separated into a number of plates that move and interact with one another. This idea aids in our understanding of mountain range creation, volcanic activity, and earthquakes.

9 grasping how the physical world behaves starts with grasping the concept of energy. Energy can only be changed from one form to another; it cannot be created or destroyed. The conservation of energy is the name given to this idea.

10 As part of the Human Genome Project, the human genome—the entire collection of genetic material in a human cell—was first sequenced in 2003. This outstanding accomplishment has created new opportunities for comprehending human biology and creating personalised therapy.

The enormous and interesting realm of science is only partially illustrated by these facts. There is so much more to look into and learn about!
