And, by the way, this is not a new experiment at all. People in the Middle Ages devoted themselves to this issue, sincerely and diligently.  Zero is actually the very old black.

Today we can trace the results of their sophisticated experiments in the form of refined art, philosophy and religion.

While mathematical zero emerged as an essential element to advance science in the modern world, “sunya” continued to inspire various forms of art and philosophy in many Asian countries.  Buddhists especially devoted themselves to the issue of “emptiness” and “void.” This concept is expressed by   in Chinese character, which means “sky”, “emptiness” and “void.”

Buddhism is a religion of  “Zero (). ” 

Buddhism’s core belief is to achieve Nirvana (the imperturbable stillness of the mind after the fires of desire, aversion, and delusion have been finally extinguished) to free ourselves from all kinds of sufferings.  Sufferings are the product of desire and lust.  If you stop “wanting,” then you no longer have to suffer.  Once you reach Nirvana you almost merge with the vast universe;  you acquire the eternal truth.

One school of Buddhism, Zen, has a distinct characteristic: it denies text as a means to acquire the eternal truth.  Religious text is inherently prone to multiple interpretations. You could lose the critical truth when you are mired into disputes to decide which interpretation is correct. 

Zen believes that the state of Nirvana can only be achieved through physical, mental and cognitive training (most notably by meditation).  All the religious truth has to be inside yourself, not external to your body, like text.
