Even in the world of physics, many of the greatest theories, are generally accepted as truth. Even though we do not have concrete evidence of things such as the big bang, there is an element of “faith” involved in their conception and progression.
Even in the case of string theory, scientists “believe” that this may unlock the key to the secrets of our universe and unite the two great adversaries: General Relativity and Quantum Mechanics. But surely one day someone will ask: What gives strings their energy? What are the strings themselves made of?
So even in the world of science where generally proof is generally mandatory, it seems you cannot escape faith and belief as the force that drives it!
Maybe science and spirituality are not so different after all?
