Hi,
I am not a scientist so my understanding of space-time is based on books, magazine articles, and internet searches that are light on math.
If space-time is a fabric or foam that can be warped, what makes up the fabric or foam? From what I understand, so far, string and M theories may fit in somewhere.
Do strings make up the "membrane" in M theory? Is this "membrane" the fabric or foam of space-time? I am probably way off track and thought I might find some answers here before I become terminally confused.
Thanks,
Tom C
