Relatively speaking

Einstein proclaimed E= mc squared
Before his conclusions, nobody cared
He offered his conjecture, he really knew
Before his existence, we didn't have a clue

His life was filled with deep contemplation
Of how we move forward, it's all in relation
For every action there's an equal reaction
One hundred percent, or whole as a fraction

The planets revolving at the same speed
The species evolving, together indeed
He looked for the answers, always seeking
Einstein delivered, relatively speaking
