Paris in the Summer When It Sizzles

The weather in Paris has been quite warm this week, around 80 F. After Houston and 100 F temperatures, the weather seems cool. The climate is getting better for new ideas in physics. The "Invisible Universe" conference heard a variety of alternatives to cosmology's standard model. MOND received particular attention, culminating in a long talk by John Moffatt Thursday. Though the majority still believes in Dark Matter, a small group of researchers worldwide are still studying MOND. It is pleasing that other ideas are bieng heard and considered.

Focus on a cosmic constant as the explanation for "dark energy" has led science nowhere. Scientists are now considering a number of soultions including modifications to gravity. Alternative ideas face a high barrier in matching the "predictions" of LCDM. Soon science will learn of a Theory which actually predicts the standard parameters, and also predicts a changing speed of light.

Proportion of baryonic matter is predicted as 4.507034%, where WMAP has found 4.4 +/- 0.3%

The amount of dark mass in galaxies and clusters is 23.87%, where WMAP has found 23 +/- 4%

That leaves 71.62% for other stuff, where WMAP has found 73 +/- 4%

In solving the problem of "dark energy," GM=tc^3 has a very bright future. Pictures from Paris coming soon!

It would have been hot walking up the Eiffel tower! We have been struggling here in the heat wave. Well, it sounds like an interesting conference, and I am looking forward to reports from down south, too.

Concentrating on mathematics in the heat must be difficult! Maybe the best thing is to study early in the morning.
