Arthur Eddington: Pick up the tablecloth.
[Winnie and Frank hold up the tablecloth]
Arthur Eddington: Space. The tablecloth is space...
[Holds up a round loaf of bread]
Arthur Eddington: The sun.
[Drops it in the middle of the stretched tablecloth]
Arthur Eddington: What's happening?
Winnie Eddington: What?
Arthur Eddington: What's happening with the sun in space?
Winnie Eddington: Well, the bread is sinking into the tablecloth.
Frank Dyson: The sun makes a shape around it in space.
Arthur Eddington: Yes. Now, what happens if I do this?
[Tosses an apple into the tablecloth; apple makes an oval around the bread]
Arthur Eddington: It *wants* to travel in a straight line, but it can't. Why not?
Winnie Eddington: Because the bread is making a shape.
Frank Dyson: The apple follows the curves made in space.
Arthur Eddington: Yes. Yes, space is shaped. And *that* is how gravity works. Space tells objects how to move. Objects tell space what shape to be. And there's a way to prove it.
