    How long ago did our Sun begin to form?

    • 4.5 billion years ago

    • 45 million years ago

    • 13.7 billion years ago

    • 450,000 years ago

    Correct Answer
    A. 4.5 billion years ago
    Explanation
    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.

    A. 13.7 Billion years ago
    Explanation
    The correct answer is 13.7 billion years ago. This is the estimated age of the universe according to the Big Bang theory, which suggests that the universe began expanding from a hot and dense state approximately 13.7 billion years ago. This estimation is based on various scientific observations and measurements, such as the cosmic microwave background radiation and the redshift of galaxies.

    • Helium

    • Hydrogren

    • Oxygen

    • Sodium

    • Reality TV Shows

    Correct Answer
    A. Hydrogren
    Explanation
    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.

    How many Galaxies are estimated to be in the Visable Universe?

    • 20,000

    • 100 Million

    • 125 Billion

    • 80 Billion

    Correct Answer
    A. 125 Billion
    Explanation
    There are an estimated 125 billion galaxies in the visible universe. This estimate is based on observations made by telescopes and other instruments that can detect and study distant galaxies. The number of galaxies in the universe is constantly being refined as new observations and data become available, but the current estimate is around 125 billion.
