I got a 480/800 in verbal/math respectively (kaplan practice tests)

My GPA is 3.993/4.000 in stony brook university, and as for physics related courses (including math courses) are GPA/4.00.
I've got 2 research experiences but I haven't published anything yet (not even as a second author, but I am preparing one.).
I haven't took GRE subject yet.
I know that this information is not good enough to tell anything about the possibility of getting an admission, but does my GRE score blocks my chances of getting into top school like caltech or mit?
To be frankly, I don't think I will ever be able to score above 500 in the verbal section. Oh btw, I'm an internation student (getting a BS in the United States)and my toefl is 273 CBT.
I wasn't sure if I am allowed to ask questions in this discussion forum. But in anycases, thank you in advance for your replies!
