¿is string theory the solution to quantum gravity?

..is the only way to reach to quantum gravity..?.or are another ways..(such as canonical quantization)..i say that to have another option studying the subject.

A major alternative theory goes by the name of "loop quantum gravity". Both theories (string and loop quantum) suffer from the same fundamental problem. There has been (so far) no definitive experiment to test either theory in any meaningful way.
