The Sun’s light does NOT take 8 minutes and 20 seconds to reach Earth. It’s ridiculous.

The Sun with it’s diameter of 1,390,000 km, at a distance of 150,000,000 km from Earth, is proportionally equal to a 1cm bulb being 32.4 cm away from a Planet Earth with a diameter of 27 micrometres.
As the distance of 32.4 cm increases to 150,000,000 km, the light source’s diameter will increase by the same ratio, always staying exactly 108 diameters of itself away from the Earth, that will also increase by the exact same same ratio. As the numbers get higher, they do so in the exact same ratio, always keeping the light source 108 diameters away from an increasing diameter Earth.
To believe the Sun takes 4.6 seconds to radiate it’s own light the distance of it’s own diameter is a serious lack of common sense. And following through to the Sun taking 8 minutes and 20 seconds to radiate it’s light 108 of it’s diameters to Planet Earth, is equally as silly (To put it lightly). Other words are more appropriate, but we wouldn’t want to offend anyone.
The Sun radiates Absolute Light. It has nothing to do with science. It’s about basic common sense.
