>well the sun is obviously the closest star besides that AC is 4.3 light years away.
Gravity propulsion would take only a few hours to get there… Totally plausible since gravity propagates at 10e24 times faster than light.
(this can be observed by noting the aberrations of light and compare to gravity)
Secondly - no one has considered that SATURN is the closest star.
(saturn was one a sun) ←- the "golden age" of saturn.
Just expanding a liddle thinky.
Vampires legends date back to medieval plagues.
Silver kills it.
Garlic keeps it away.
UV (sunlight) light kills it.
It was personification of a disease.
In fact those things are true, and making a story about a villain for the children to fear makes a little sense.
It took a lot of distortion to get where the story is today!
originally: was the same source of legend for both was silver.
seems that rabies also played a part in forming the legend of wwolves.
What you describe is plausible.
The sun is electrical (of you do not already know this, see "thunderbolts of the gods" videos).
Think of lightning in a forest.
It strikes the tallest tree (largest object)
Same is true is universe whereas energy will take the path thru the largest object, so if you have a sun illuminated electrically and a larger object is introduced effectively "shorting across" the sun and bypassing it electrically (partially at least). The cosmic energy would spread across two objects "running at half brightness" as would a light bulb.
