$\mathrm{LL}$ cosmological solutions with non-vanishing density of matter known at present ${ }^1$ have the common property that, in a certain sense, they contain an “absolute” time coordinate, ${ }^2$ owing to the fact that there exists a one-parametric system of three-spaces everywhere orthogonal on the world lines of matter. It is easily seen that …

First Website
I recently took a trip down memory lane by looking at old websites. I had forgotten that my first website was published in 1996. It appeared on the University of Michigan EECS server for artificial intelligence. I was only in high school but had early JavaScript for a random quote generator. That was version 5. …
