The universe is 90 billion light years in diameter. How do scientists measure something so huge? Space Time explains the process as part of its larger Cosmology playlist. The video addresses the steps to solving the puzzle as well as how scientists managed to find the answers. Finally, the solution appears ... much like raisin bread!
- Discuss how scientists measure the distance to planets before sending an explorer to them
- Relies on prior knowledge of wavelengths and the process of baking raisin bread
- Slow video down to allow for more clarity in the spoken words
- Includes subtitles in English for ease of note taking
- Research for the video came from a Nobel-Prize-winning paper
