Question

Is gravity due to space time curvature or gravitational waves?

Answer 1

Hint: As predicted by Einstein in 1916, gravitational forces cause waves to vibrate through space-time itself. According to Einstein's theory of gravity, gravitational waves are ripples in space-time. Gravitational waves are waves that are caused by the gravitational force.

Complete answer:
Yes, gravity is due to space time curvature or gravitational waves.
Gravity is presented as a phenomena originating from the curvature of space-time in Einstein's general theory of relativity. The existence of mass causes this curvature. Gravitational waves are the name for these spreading events.
The existence of mass causes this curvature. The larger the mass contained within a particular volume of space, the greater the curvature of space-time at the volume's boundary. The curvature of space-time changes as things with mass move around in it, reflecting the changes in their locations. Accelerating objects cause changes in this curvature, which propagate outwards at the speed of light in a wave-like way in certain circumstances. Gravitational waves are the name for these spreading events.
When a gravitational wave travels through an observer, the observer will notice that space-time has been deformed due to strain. As the wave passes, the distance between objects increases and decreases at a frequency equal to the waves. The degree of this effect reduces as the distance from the source is inverted. Due to the very enormous acceleration of their masses as they orbit near to one another, spiralling binary neutron stars are expected to be a major source of gravitational waves as they combine.

Note:
Gravitational time dilation occurs because objects with a lot of mass create a strong gravitational field. In reality, the gravitational field is a curving of space and time. The more gravity there is, the more space-time curves there are, and the slower time moves.
