The most extreme example of this curvature of spacetime is a black hole, from which nothingnot even lightcan escape once past the black hole's event horizon. However, for most applications, gravity is well approximated by Newton's law of universal gravitation, which describes gravity as a force which causes any two bodies to be attracted to each other, with the force proportional to the product of their masses and inversely proportional to the square of the distance between them. Gravity is the weakest of the four fundamental interactions of physics, approximately 10 times weaker than the strong interaction, 10 times weaker than the electromagnetic force and 10 times weaker than the weak interaction.", 'Gravity']}}]}, {'provenance': [{'wikipedia_id': '38579', 'title': 'Gravity', 'section': 'Section::::Abstract.', 'start_paragraph_id': 1, 'end_paragraph_id': 1, 'meta': {'evidence_span': ['Gravity (), or gravitation, is a natural phenomenon by which all things with mass or energyincluding planets, stars, galaxies, and even lightare brought toward (or "gravitate" toward) one another.', 'Gravity']}}]}]
