How can Babble know the grass is green when it cant see?
The same way we know that a battery has a certain charge even though we cant sense it. We understand that things have different attributes such as color, shape, temperature or charge. We can process that information without observing it. Of course observation gives us a richer experience of the attribute, so Babbles experience of grass is not very rich. This is discussed in more detail in the white paper.
