I don't think it would be ethical to recreate the universe in a lab...and I don't think there would be enough room smile
Even if a micro cosmic Universe were created...once we created it I doubt we would have much control...it would be under the control of natural forces just like ours is. It would just be a tiny aspect of our greater Universe and not a seperate universe. The closest thing to a seperate universe could only be created in the imagination. I guess there are tons of those on Sci-Fi book shelves.
