I know Superman once turned back time in the movies, but maybe he realized it was a bad idea and decided to never do it again.
Because it is unethical to re-write history. I don't think he would consider it an option to beat the Hulk.
And as far as Superman being able to move near the speed of light, so can the Hulk.
Because the Hulk has the ability to hurl himself into orbit by just jumping from the surface of the earth. Hulk can also survive in outer space without oxygen.
Superman could not throw the Hulk into outer space, because the Hulk is way stronger. Superman's laser's would be like a flee landing on the Hulk's back.
All the Hulk needs to do is grab Superman. If the Hulk grabbed Superman's arm, he can then punch Superman once. And Hulk's tremendous powerful punch will kill Superman. It would be like BOOM, and there would be an explosion on Superman's chest. And look now, there is a hole in Superman's chest the size of Hulk's fist.
And seriously, how much do you think Superman could bench press, maybe about 500,000 tons. How much could Hulk bench press? If he wanted to he could bench press the entire universe and barely break a sweat.
