Tuesday September 16, 2003. I got a fair amount of writing done and printed out -- for inspection, not yet for workshopping. (And definitely not ready for submission.)

The printing problem had been solved by turning off the computer and turning it on again.

Mail: First Draft #65. First Draft is a bimonthly postal writing group in apa format. Thinner than usual -- only 102 pages. The OE is nervous about this, and about the longest contribution being only 36 pages. Work includes mainstream fiction, already-published newspaper pieces, mystery, fantasy, poetry. Sample copy for cost of postage (A bit under $3 for this one; next one likely a bit under $5) to Michael Wolff, PO Box 62351, North Charleston, SC 29419.

Penzys Spices postcard -- besides the stores in Minneapolis and St. Paul, they now have one in Savage, MN.

Applied Physics Letters
Ceramics reinforced with nanotubes
A ceramic material reinforced with carbon nanotubes has been made by materials scientists at UC Davis. The new material is far tougher than conventional ceramics, conducts electricity and can both conduct heat and act as a thermal barrier, depending on the orientation of the nanotubes.

The universe may have been created by an explosion within a black hole, according to a new theory by two mathematicians recently published in the Proceedings of the National Academy of Sciences of the U.S.A.

"It's a mathematically plausible model which refines the standard model of the Big Bang," said Blake Temple, professor of mathematics at UC Davis and co-author of the paper with Joel Smoller, professor of mathematics at the University of Michigan.

In the new model, the Big Bang is an actual explosion within a black hole in an existing space. The shock wave of the explosion is expanding into an infinite space, leaving behind it a finite amount of matter. The universe is emerging from a white hole. The opposite of a black hole, a white hole throws matter out instead of sucking it in.

The shockwave and the universe beyond the black hole lies in our future. Eventually, the universe will emerge from the black hole as something like a supernova, but on an enormously large scale, Temple said.

The equations that describe a black hole were written by Albert Einstein as part of the General Theory of Relativity. Einstein's equations work equally well if time runs forward or backwards. But explosive shockwaves, which include an increase in entropy, are time-irreversible. The new theory satisfies Einstein's equations while allowing the universe to expand.

Whether the matter emerging from the white hole came from matter that previously fell into another black hole is an open question, Temple said.

"It is natural to wonder if there is a connection between the mass that disappears into black hole singularities and the mass that emerges from white hole singularities," Smoller and Temple wrote.
