Welcome to the "How Far Does Light Go?" project. This project is a debate of two different theories about how far light travels. In this project you will carefully examine evidence related to the debate.
But before you start looking at evidence, you need to think about the two theories:
- LDO THEORY: Light dies out and stops as it travels further from its source. This distance is different for different light sources.
- LGF THEORY: All light goes forever, until it is absorbed.
You will be asked to defend one of these two theories during the debate portion of this project.
