Q: Is gravity responsible for many of the structures in the Universe? ¶
A: Yes, and by creating spheres of hydrogen — where hydrogen fuses under pressure to form stars — and grouping them into galaxies.
Q: Is gravity well approximated by Newton's law of universal gravitation? ¶
A: Yes, and which postulates that gravity causes a force where two bodies of mass are directly drawn to each other according to a mathematical relationship, where the attractive force is proportional to the product of their masses and inversely proportional to the square of the distance between them.
Q: Is gravity equal to the speed of light? ¶
Q: Is gravity most accurately described by the general theory of relativity which describes gravity not as a force but as a consequence of the curvature of spacetime caused by the uneven distribution of mass/energy? ¶
A: Yes, and resulting in gravitational time dilation, where time lapses more slowly in lower gravitational potential.
Q: Is gravity equal to this g? ¶
A: Yes, An initially stationary object which is allowed to fall freely under gravity drops a distance which is proportional to the square of the elapsed time.
Q: Is gravity the weakest due to the centrifugal force caused by the Earth's rotation? ¶
Q: Is gravity the weakest of the four fundamental interactions of nature? ¶
Q: Is gravity indistinguishable from certain aspects of acceleration and deceleration? ¶
Q: Is gravity the dominant interaction at the macroscopic scale? ¶
A: Yes, and is the cause of the formation, shape, and trajectory of astronomical bodies.
