The observable universe. Does it mean the edge of space where nothing else is? Is it where the universe is currently at in its expansion after the big bang? Or is it just a barrier that our telescopes are yet to look beyond, and there are just more galaxies past it?

This is a really dumb question as I have been able to understand the majority of the responses and I thank you all for dumbing it down far enough for me to do so. I am wondering what “c” stands for or represents as there has been responses with talk of 1c, 2c and 4c?
Thank you
