I have always wanted an answer that I can understand to the following
question.

Simply asked, "What is our Universe expannning into"?

Please explain it assuming I am an *ordinary* 13 years old.

I finally found this question and its answer, in a FAQ called
"Frequently Asked Questions in Cosmology":

http://www.astro.ucla.edu/~wright/cosmology_faq.html

It is all "%^$@^$%@^" to me. :-(

Thanks in advance to "anyone/everyone" who can explain it to
me so that I understand.

Look at a cell in a spreadsheet. Put in a value of 1. Increment the value
by 1. Allow iteration, and have the formula self-increment. What is the
cell "expanding into"?

Spacetime is similar to a giant spreadsheet that quantum mechanics plays
out on. We're just trying to figure out the formulas that populate it.
