Our universe certainly seems real, but in recent years a growing number of scientists have begun to wonder if it’s all just a sophisticated simulation. Are we and everything around us nothing more than points of data in some sort of cosmic hologram? A group of celebrated scientists, including Neil deGrasse Tyson, will sit down on Tuesday for a serious discussion of what may sound more like a sci-fi movie plot than reality.

I suspect it's beyond our capability to understand, so all we can do is come up with models and analogies. In addition to trying to find out how it works, we also want to know why. There are hints and clues, but always some doubt as well, which leaves us free to choose.
