The Singular Universe

Here are a few additional notes and comments relating to a review of The Singular Universe and the Reality of Time published in The Guardian.

the distinction between past, present and future is only an illusion      Health warning: cosmologists are not saying it is OK for you to be late. See, e.g., Sean Carroll.  See also The Now.

[added 16 February]: Time Reborn there is a fascinating critique of Time Reborn by Joe Boswell here

physicists in the academy groan     Smolin is based at the Perimeter Institute outside the academic system.  The quality of its people can be gauged in the commitment of its director Neil Turok to, e.g., education in Africa.

deep freedom     openDemocracy published an edited extract from Roberto Unger's Religion of the Future here.   See also his site and talks.

prophet – or...crank     Jeremy David Bendik-Keymer writes "Unger may think of his work as preparation for prophesy, but it ends up as pontification."

some essential points can be readily grasped     Lee Smolin has written a handy summary of key ideas for New Scientist. Roberto Unger outlines some in audio with A universe in which everything changes sooner or later.

It appears there will be some errors in the print version of my review.  For example, cosmic inflation is thought to have begun 10-37 seconds after the big bang, not 10-37.  Also, I think it is correct to say that Unger and Smolin are only saying that parts of this model are preposterous, not necessarily all of it.

For A New Map of Wonders I have blogged in connection with Unger here and Smolin here.

Finally, Rilke's ninth Duino elegy has this:
Once for each thing. Just once; no more. And we too
just once. And never again. But to have been
this once, completely, even if only once:
to have been at one with the earth, seems beyond undoing
