This article explores the search for the first animal, or the common ancestor of all animals that lived over 600 million years ago. It covers the earliest evidence of life, the first animals, and the rise of multicellular organisms. The search for the first animal remains an exciting and challenging area of scientific research. The […]
The polar night is a period of continuous darkness that occurs during the winter months at the Earth’s poles. It is caused by the tilt of the Earth’s axis and has significant effects on the environment, living organisms, and human health. Despite its challenges, the polar night also has scientific and cultural significance. Long Version […]
The scientific consensus is that humans evolved on Earth over millions of years through a process of natural selection. Our earliest ancestors diverged from other primates around 6-7 million years ago, and over time, evolved into the modern human species we are today, Homo sapiens. As to the purpose or reason for our existence, that […]
There is no way to predict exactly when an asteroid will hit Earth, as it largely depends on the trajectory and characteristics of any asteroids that might be on a collision course with our planet. However, scientists are constantly monitoring near-Earth asteroids and comets and studying their orbits to identify any potential impact risks. Fortunately, […]
The sky appears blue because sunlight is scattered in all directions by the Earth’s atmosphere, and shorter wavelengths of light (such as blue) are scattered more than longer wavelengths (such as red).
