Please edit my essay? (its just a little part, will not take long)?

this essay is really really boring and factual. rev it up alot. in first sentence, use started instead of starts because he is dead now and his experiment was a long time ago. combine sentence 2 and 3 to make " he published the article( or whatever it was) The General Theory of Relativity in 1915, which demonstrated how light rays bend in a strong grav field." get rid of sentence 4. switch sentences 5 and 6 because they are out of order. sentence 7 use left instead of leaves for said reasons. i think u can do better whoever you are
