"A radical new project could permit human beings to create a "baby universe" in a laboratory in Japan. While it sounds like a dangerous undertaking, the physicists involved believe that if the project is successful, the space-time around a tiny point within our universe will be distorted in such a way that it will begin to form a new superfluid space, and eventually break off, separate in all respects from our experience of space and time, causing no harm to the fabric of our universe."Um, yeah, can we maybe not do this? How sure are we about the "causing no harm to the fabric of our universe" part? That sounds important...
