its called ToE because its a Theroy .. its the best scientists can do with the current understanding of the evidence , and the current technology.. it is open to change , reinterpritation and additions and deletions.. thats how science works .
Pluto was discovered by looking for a object that was affecting Neptune orbit , at the time early 1900's it was a major echivment to find the object give the avaiible technology ... advances in technology have show Pulto is less massive than first measured , it has a odd orbit , its make up is more asteroid like , and that there are many other Pluto-like objects out there which are clearly different from Planets ... much of the new info comes from hubble the space based telescope .. compare to the 1900's technology to see the advancement
thus science has done what it always does , taken the new data and looked at reality of the situatiion and updated its view .
this is how science works ...
