In 1916, the year after the final formulation of the field equations of general relativity, Albert Einstein predicted the existence of gravitational waves. He found that the linearized weak-field equations had wave solutions: transverse waves of spatial strain that travel at the speed of light, generated by time variations of the mass quadrupole moment of the source [1,2]. Einstein understood that gravitational-wave amplitudes would be remarkably small; moreover, until the Chapel Hill conference in 1957 there was significant debate about the physical reality of gravitational waves [3] The Child of General Relativity.

Gravitational Potential Energy & Kinetic Energy  GPE When you lift an object up, energy is transferred from your muscles in to gravitational potential energy of the object. Gravitational potential energy (GPE) is energy stored in an object because of its position in the earths gravitational field. Alexander . Polnarev. QMUL, School of Physics and Astronomy, London, UK.
