Dinosaurs dominated the Earth for over 160 million years, a testament to their remarkable adaptability and evolutionary success. Several factors contributed to their dominance: Overall, the combination of evolutionary innovations, ecological diversity, reproductive success, and global distribution enabled dinosaurs to dominate terrestrial ecosystems for millions of years.

What is time?
Time is a concept deeply ingrained in human perception and understanding, yet its essence remains elusive. At its core, time represents the progression of events from the past through the present and into the future. It is the dimension in which events occur sequentially, allowing for the measurement of durations and intervals. From the ticking […]
What is Oligospermia?
Oligospermia is a condition characterized by a low sperm count in a man’s semen. It’s typically diagnosed when there are fewer than 15 million sperm per milliliter of semen. It’s one of the causes of male infertility, as a lower sperm count can reduce the chances of fertilizing an egg during sexual intercourse. Oligospermia can […]
What is DNA?
DNA, or deoxyribonucleic acid, is a molecule that carries the genetic instructions for the development, functioning, growth, and reproduction of all known living organisms and many viruses. It is often referred to as the “building block of life.” DNA is composed of two long chains made up of nucleotides, which are molecules consisting of a […]
What is Gyroscope?
A gyroscope is a device used for measuring or maintaining orientation and angular velocity. It typically consists of a spinning wheel or disk mounted on a base that allows it to rotate freely in any direction. When the gyroscope rotates, it tends to maintain its orientation in space, resisting any external forces that attempt to […]
What is subatomic particles?
Subatomic particles are the fundamental particles that make up atoms. Atoms are composed of a nucleus, which contains protons and neutrons, surrounded by a cloud of electrons. The three main types of subatomic particles are: Besides these fundamental particles, there are also other subatomic particles, such as quarks (which make up protons and neutrons), leptons […]
What is cosmology?
Cosmology is the branch of astronomy and astrophysics that deals with the study of the origin, evolution, structure, and eventual fate of the universe as a whole. It seeks to understand the large-scale properties and dynamics of the universe, including its overall shape, composition, expansion, and the distribution of matter and energy within it. Cosmologists […]
What is dark matter?
Dark matter is a mysterious form of matter that makes up about 27% of the universe’s total mass-energy content, according to current scientific understanding. Unlike normal matter, which consists of atoms and subatomic particles, dark matter does not interact with electromagnetic forces, which means it doesn’t emit, absorb, or reflect light. This property makes it […]
