Part One: Exploring a Spongy Universe

When you have received a sponge from your instructor, follow these instructions.

Step One: Feel the sponge and describe in detail what you feel.

Step Two: Describe the process you think was used to form the holes while the sponge was being made?

Step Three: Read Part One of “The Spongy Universe” student text and be prepared to answer the following questions:

When do you think that the “Hubble bubbles” formed—early in the formation of the universe or late in the history of the universe? Why do you think this?

What do you think caused the formation of the “Hubble bubbles?’ What information or observation led you to this conclusion?

Do you think that there is anything in those "voids" that we cannot see or detect with scientific instruments? Why or why not?
