Hello Sputnick,

I for one hope the sun's gravity is fairly constant because the only way I could envision the Earth speeding up by having the distance between us and the Sun decrease. In other words, were goin' in!

I think at last look er were slowing down.....Whew.

Hello All

My goodness - I just went back and read plasma further - "The Sun may be powered, not from within itself, but from outside, by the electric (Birkeland) currents that flow in our arm of our galaxy as they do in all galaxies." Oh my goodness .. I could be right after all.
There is a connection throughout the galaxy. But! the main power from the sun is generated by fusion and fission chain reactions.
The Electric theory has alot going for it in combination with plasma cosmology.

Two theories:

1) The standard model, burning Hydrogen. You can google for this info.

2) The sun years gone by was formed on a remnant Neutron core after a supernova. This Neutron core having a density of 10^ 17 Kg/m3 has had enough matter and energy to last 12 gyrs.
You can read up on it:

NASA is sending a probe in the near future to study the Sun and from this probe I hope many issues will be solved.

Last week's High Energy Astrophysics Picture of the Week (HEAPOW), Filigree, pictured the hot gas linking two galaxy clusters.

Hello Bystander,

If I put one more link in "Favorites" I think my hard drive will start televising nasty notes on my monitor. I took the chance anyway and installed your link. It's fantastic, thank you!

G'day

The link

Is fantastic.

Now I know what they did with the BLOB.
