Debating evolution

Age of the Earth? Specifically.
How Old is the Earth: A Response to "Scientific" Creationism

He's correct this far - but I just posted this aweek ago that lets us estimate how much mass the Sun has lost in the last 4.55 billion years - and it comes out to a little under 0.05% from matter that is converted to energy. A minute fraction more - maybe a millionth of that? - is also lost as the solar wind.
ref:
http://csep10.phys.utk.edu/astr162/lect/sun/wind.html says ten million tons per year for the solar wind, where the mass->energy conversion is 4.3 million tons per second.

Nope. Sirius A is spectral class A0 - white or bluish white. The companion is far too faint and close to it to see naked-eye - a ten-thousandth as bright.The description of Sirius as "red" very likely is because it looks red when it's just rising over the horizon, just like the Sun does. The first pre-dawn rising of Sirius was what told the Egyptians that the Nile was about to flood - the most important astronomical event of their year. It was red at the important moment, but once it was up in a dark sky it was the same color 3000 years ago as now.
