Why Does Betelgeuse Dim?

Why Betelgeuse Dims

This orange-red picture shows the star Betelgeuse, as witnessed by the Atacama Large Millimeter/submillimeter Array (ALMA). This image results from ALMA's first-ever observation of a star's photosphere and the highest-resolution image of α Orionis available. The star has a measured radius of some 1,400 times that of the Sun's and lies about 600 ly away.

Stars are electrically connected with their galactic neighborhood and with the Universe. They shine because electricity flows through galaxies.

They can be thought of as giant spheres of electricity - a simple hypothesis that matches observational evidence. Now with proof from the Safire project, we have experimental evidence for this.

Red giant stars are large, relatively cool celestial objects but extremely bright. However, their enormous sizes are due to them having large coronae, not because they're oversized.

Electric currents in space are due to the flow of electrons through interstellar plasma rather than the motion of anions. Red giants have a deficit of electrons because of charge separation.

All the stars in every galaxy, red giants or not, are anodic in a galactic glow discharge. Red stars cannot satisfy their demand for the negative charge from local space plasma, so they expand in volume to increase the surface area over which electrons can be collected. In so doing, they develop sizeable anodic plasma sheaths that become effective electron-gathering areas in space.

A red giant's growth is self-limiting because, as a plasma sheath expands, its electric field strengthens. Electrons caught in the field are, therefore, accelerated to ever-greater energies.

Sooner or later, the electrons become so energetic that they excite local neutral matter, and the enormous sheath takes on a uniform red anodic glow.

Betelgeuse is, therefore, an electron-hungry anode in space. Its bright regions are areas where electric currents flow with the greatest Amperage. When that current drops, the star dims. That's why the brightness of the star plunges by about a magnitude. Betelgeuse is not about to 'blow up,' as misled astro scientists believe.
