The Universe is surely a vast, infinite place with an infinite number of forms of matter. The Universe is the house for all that is large and unseen (except with the aid of a telescope) as well as small and unseen (except with the aid of a microscope). With that said, please collect data on three objects found in the universe. For example, you can describe a certain planet, certain building, or certain animal; however, the object should be considered "extreme" in a large or small sense. (An example that you cannot use specifically would be Mount Everest - which is known for its extreme height.) In a blog post, please post the name of each object as well as the reported measurements of the objects. Also, include the link or source of the reported measurements.

Hi. I am doing the Lab right now, and I am stuck on one question. When we report the measured value of flask as "average +/- absolute error". They require the error rounded to one digit. My error is 0.006. I do not know how to round it to one digit. Can anyone help me?
