The earths mass is being sucked into the sun by the suns gravity

If the chemistry of solar systems is constantly changing it makes it much more
likely that at some point there will be life in the system. Maybe even life at different times and on different planets in the same solar system.

Maybe gravity is the spark that keeps the sun burning?
When electricity encounters resistance in a wire it slows down and heats up the wire.
Maybe when the sun sucks gravity into it, the gravity encounters resistance and slows down causing the sun to burn. a spark plug

Well, the idea that gravity is the spark that keeps the sun burning, isn't far off. Gravity compresses the sun's matter and keeps it from flying apart from so much heat, so the hydrogen-to-helium fusion process can continue. Without gravity the sun would expand and go out.
I don't think electricity slows down when it meets a resistance, though. At least the voltage doesn't...maybe the individual electron free paths get shorter or something, but the voltage signal will appear at the same time at the end of a long wire, regardless of resistance. Inductance may be another matter, though.

Evidence? The moon moves away from the earth 3cm per year. Hmm.. maybe its instead the earth that shrinks 3cm per year due to loss of mass

That surely is offset by the gains in mass from all that middle-aged spread, that makes me add an inch to my waist size each year.
