21.   In fact, the pages of this newspaper have a greater gravitational force on you than do these five planets.

22.   Newton calculated that if the planet and the Sun double their distance from each other, there is only one-quarter the gravitational force between them.

23.   Olvey said the lateral gravitational forces give the drivers the feeling of being compressed into the car.

24.   Olvey added that if pilots in NASA or in military service experience those types of gravitational forces, they would wear G-suits.

25.   One might even be sent to hover over and obtain direct images of the consuming gravitational forces at regions known as black holes.

26.   Other candidates to represent the missing mass have been small black holes, regions of intense gravitational forces, or else such dead stars as white dwarfs.

27.   Small scale disturbances, like wind or vibrations would topple the egg even if gravitational forces were at bay, he said.

28.   Strong gravitational forces pulled the other way.

29.   Sure, gravitational forces do affect people, said Stuart Vyse, a Connecticut College psychology professor and expert on superstitions.

30.   The brightness is the result of the extreme gravitational forces acting on the material.
