I love when I hear someone express that relativity is more then just Albert Einstein's theory but in a more literal sense using analogies such as the ocean being endless compared to the vastness of the Universe. I also think this way and it makes the most sense I think. What is small can be compared to what is big and vice versa. Thought can be used to think about what may be but when you boil it down to the basic levels of comparison the most impressive thinkers use simple concepts like Martin.
