//Talking about gravitational pull
Schafer: So if Alan and Shariar are one meter apart, the gravitational pull would be-
//Alan scoots closer to Shariar
//Shariar sits awkwardly

Schafer: Yes! But the gravitational pull is so little you cannot see it.
Student: Could Shariar be accelerating away?
Scafer: Well, there are both attractive and repulsive forces...
