I'd like to introduce this thread for anyone to give any ideas on what is beyond outer space, how far does it go, what its made of, etc.

I've thought about it and if you look at the way the worlds features are made, mostly, they are individual cells combined with other cells that make up eventually form a living object. We are made of millions and millions of cells.

But what if the universe works the same way? It has been proven that we are within a spiral galaxy, and there is more than just our galaxy. What if all these galaxies around us combine to make this huge galaxy called the Super galaxy, and all the Super galaxies combine to make a Mega galaxy? And it just keeps continuing. Is that possible? There can be so any ways to look at it, the thing that is providing so much thought of it is we don't know everything that's out there, yet.

If anyone has ever thought about this, or anything closely related please feel free to share your theories
