In String Theory what are strings actually made of?
Hmm, that's pretty cool. Is there any evidence to support the existence of strings?
While there is currently no direct experimental evidence for strings, many theoretical physicists believe that String Theory has the potential to unify all of the fundamental forces of nature, including gravity, into a single framework. So while there may not be concrete proof yet, the implications of String Theory are quite intriguing.
