This will be my last regular post for a while because of Christmas and teaching three courses next term at my University. These past eleven posts, see here and here, have been my personal take on many of the topics covered in On Space and Time and its now time in this twelfth post to […]

After last week’s imaginative speculation, I’d better tell you something concrete. How about the solution to quantum gravity that has been eluding us for some 90 years? Here it is … er … with one minor catch. We’ll have to suppose that spacetime is 3 dimensional, i.e. one time and only two space directions rather […]

So far in these posts we have looked at testable quantum gravity effects, but I have not said much about the ultimate theory of quantum gravity itself. There is a simple reason: I do not think we have a compelling theory yet. Rather, I think that this deepest and most long-standing of all problems in […]

First off, newly syndicated readers who want to have access to my previous posts can find them archived here as well as listed on my own site here. After last week’s speculations on time I would like to ask an even deeper question: why is there time? My 4 year old daughter would be proud. […]

First off, congratulations America! Electing the first black US president has to be significant and already puts Obama into the history books, whatever economic and other problems may loom worryingly in the future. Certainly his work will be cut out for him given the falls in the stock market and some of the dire predictions […]

If the real world, at its base, is quantum, then should we not think with quantum logic? Shahn Majid discusses how the notion of quantum symmetry coming out of modern ideas on space and time could provide clues to the workings of a truly quantum computer. Have you ever sat through a really boring flow […]

Is it impossible to pin down both where and when an event takes place, due to quantum gravity effects? Shahn Majid explains why this may be. In these posts I have emphasized ideas on the cutting edge of fundamental science which have testable predictions or other contact with experiment, rather than being merely fashionable. Now, […]

Continuing his series of posts on space and time, Shahn Majid examines some of coauthor Roger Penrose’s revolutionary ideas. Could we, today, see remnants of a previous universe? Past lives and life after death are paltry matters compared to Roger Penrose’s latest ideas about the origin and fate of the Universe itself. In his chapter […]
