Seth Lloyd's new time idea
This is given here and already much discussed in the media.
Others suggest a problem: Briefly.... "One reason is that Seth Lloyed and others belive that the Universe is in effect a self calculating computer. Which effectivly means that our physical universe is a very very small subset of the information universe.
Now there are two problems if the physical univers is a computer then it is determanistic in some form. Which our normal definition of randomness indicates that randomness therefore cannot be a product of our physical universe.
So it must either be caused by something external to the universe. Or our assumptions that give us our definitions are wrong...."
IMO: Very roughly, this occurs because only the B series and not both the A and B series are considered. I try to consider both, e.g. in my other blog.
