It's time for another t-shirt challenge question! Make sure you're brushed up on your math and high-school level physics before trying this one! There will be 5 winners from each challenge! Do NOT submit to both!

Email your answers to: pbsspacetime@gmail.com before 5pm NYC time August 24, 2015.

Make SURE you title your email: "Two-particle Newtonian gravity challenge"

For the Einsteinian challenge title your email: "Two-particle Einsteinian gravity challenge"


Good luck! And we will see you next week on Spacetime for Gabe's final episode.
