Light Year
Storyboard Text
- And God said, “Let there be light,” and there was light.
- In the beginning, there was only darkness.
- The earth was formless and empty, darkness was over the surface of the deep, and the Spirit of God was hovering over the waters.
- Nearly every single person in the world knows of the biblical thinking of how the world was created. Light came into the world first, as evidenced by its extraordinary speed, and that is exactly what this is about.
- Light travels at about 299,792 km/second, or 1,079,251,200 km/hr. That's really fast! Imagine how far light could travel in a year! That is exactly what scientists call a light-year! A Light-year is how far light can travel in one year. Well, in this comic, we are going to take you through the history of the light-year and what it is.
- Friedrich Bessel - first to measure the distance to a star other than the sun. He used the distance that light might have traveled in a year in his data and analysis. This was the first incarnation of the light yr.
- Look! I have found the distance to 61 Cygni!
- Otto Eduard Vincenz Ule, a German writer with a Master's Degree in Science, used the term light-year in his popular astronomical article, and used the concept of hours hiking on a road to describe the usage of time as a distance. After the publication of his work, the light-year was seen as irrelevant to the study of light.
- And there you have it! The light-year is measure of distance based on how far light travels in a year. It has a long history of being used by German scientists, and today, it is considered a universal unit of measure. It has become used in popular culture vis-a-vis many famous books and movies.
