9-year-old tackles college full time, plans to become astrophysicist

PITTSBURGH, Pennsylvania - A Pittsburgh boy is making his course load look like child's play.

At 9-years-old, Will Maillis is a full-time college student. His parents say he was adding numbers at only 1 and a half years, and multiplying at 2 years old. By 5, he was counting in Chinese.

Will graduated from high school earlier this year and is now tackling a full schedule at a community college. His goal is to become an astrophysicist.

"The reason that the universe is expanding is not because dark energy overpowered gravity but because of gravity," said Will. He currently has straight A's. Next fall, he'll begin at a private research university Carnegie Mellon University in Pittsburgh.
