Sirius A is a main sequence star, of about 2 solar masses, and its
companion Sirius B is a white dwarf of about 1 solar masses. Once Sirius
A goes giant, it is possible that matter will be sucked into Sirius B.
If Sirius B thereby reaches the Chandrasekhar limit of 1.4 Solar masses,
it will supernova.
Can anyone estimate whether this process will actually take place, and
if so when? At nine light years, what would be the effect on Earth?

I read about the above Gamma Ray Burst,
but days,weeks, months later no published analysis
materialized, that I have found. Are the astronomers
still consolidating the data for peer publication?
Anyway what's the "fallout" ?
I quite interested in a "neutrino shock wave" that
occurred like SN1987a, but this burst, at a greater
distance, might produce a definite variation of the
neutrino speed to light speed.
Comments very welcome.

Just noticed in the latest Scientific American a 2 page advertisement for a
book, "Our Undiscovered Universe" subtitled "Introducing Null Physics". The
book has a web site at www.ourundiscovereduniverse.com.
I'm no physicist but from looking at that web site- the subject/concept
looks flakey. That's OK, there's plenty of flakey scientists and non
scientific concepts such as creationism- but they seldom have 2 page
advertisements in Scientific American- so, what's up with this "new"
physics? Does it have any respect in the scientific community?
