Review of Planck Time Norretranders, The User Illusion, 1998
"The Planck time covers the first 0.0000000000000000000000000000000000000000001 (1E-43) seconds after the beginning of everything.
All our normal concepts break down… time, space and matter cannot be told apart… Actually, the laws of physics do not operate in such a world… So many are happy just to trace the universe back to the Planck time. But not all cosmologists are satisfied… It is a bit much to undertake a mental voyage fifteen billion years back in time to find the beginning of everything, only to give up a fractionof a second before it all began!"
