Our Sun began to form approximately 4.5 billion years ago. This is based on scientific evidence and the age of the solar system. The formation of the Sun is believed to have occurred through the gravitational collapse of a giant molecular cloud. This process eventually led to the ignition of nuclear fusion in the core of the protostar, marking the birth of our Sun.Rate this question:

Hydrogen is the most abundant material in the known Universe. This is because hydrogen is the primary building block of stars and makes up about 75% of the elemental mass in the Universe. It is found in large quantities in stars, gas clouds, and even in interstellar space. Additionally, hydrogen is the main component of water and many organic compounds, making it essential for life as we know it. Therefore, due to its widespread presence and importance in the Universe, hydrogen is considered the most abundant material.Rate this question:
