Moving on a never-bending light...
The Black sabbath never heard of Einstein,
but they knew the nature of light is not
just physical quants and waves,
light, the light of the stars and the Sun is spiritual thing.
And it never bends, in contrary to Einstein who stole the discoveries of other people
never acknowledging them.
The nature of his discovery, the famous Sun eclipse experiment
proving the light of the stars bends by the Sun,
but they were poets, they just knew moving on a never-bending light.
Light never bends , it goes straight ahead,
and if you bend something, you bend the Truth.
You can know liars by their bending and trimming, making things nice.
