The scientific method requires good scientific theories to build theories based on observations/experiments that make specific predictions about the outcomes of future observations/experiments. Itâ€šÃ„Ã´s okay if we donâ€šÃ„Ã´t currently have the technology to make an observation. Theories are perfectly capable of sitting on shelves waiting to be proven right or wrong. What matters â€šÃ„Ã¬ what makes the theory science â€šÃ„Ã¬ is that the theory is eventually provable (or disprovable).
So, how do I deal with string theory?
