1. What is the Earth compared to Is the comparison useful in understanding the infiniteness of the universe
2. What methods does the presenter use to enable viewers to understand this piece of knowledge in physics
The size of the Earth within the observable universe is roughly equivalent to the size of a virus within the solar system That docs not help much, because we really appreciate the incomprehensible smallness of a virus nor the bewildering bigness of our solar system either.
The presenter provides comparisons that are relative to our knowledge.
What have you learnt about the size of the universe Find more information online and share with the class.
The universe is constantly expanding: According to the Big Bang theory, space and time emerged together about 13.799±0.21 billion years ago, and the universe has been expanding ever since. This expansion causes the distance between celestial bodies to continue to increase, which also makes the size of the universe constantly changing.
