Is there anything else other than string theory attempting to combine quantum physics and relativity?
I just finished my bachelor's degree in electrical engineering for reference. I will begin my master's studies in theoretical physics this fall, because I fell in love with it during my bachelor studies. Specifically understanding the universe more fundamentally is what interests me the most. I'm just quite skeptical of the current state of physics regarding this topic. String theory is the main attempt to answer many of the important questions, but so far there is no experimental evidence to support it. I am absolutely not qualified to critique it in any theoretical level, but it seems quite suspicious. I am aware of loop quantum gravity and some others, but not sure how active those areas are. It seems like everything is put into string theory, but nothing much is coming out of it. Is there
Is there anything else outside of string theory that is worth looking into?
