At first they said gravity is attraction between objects and now they say it is actually the bending of the space-time fabric. To elaborate, gravity is not simply a force of attraction between objects, but rather a consequence of the bending and warping of space and time, which together form what is known as space-time. And thus the concept of gravity has evolved over time as our understanding of the universe has deepened. Yet they have not an iota of understanding what exactly is this space-time fabric. As an analogy, on a tightly stretched cloth if you put a heavy object it creates a warp into which other objects fall if they come in the vicinity where the bending takes place. Similarly, in the case of gravity, objects move along the curved paths created by the warping of space-time caused by massive objects.



Massive objects, such as planets or stars, warp the fabric of space-time, causing other objects to move along curved paths or orbits within this warped space-time. It is the detection of gravitational waves, ripples in space-time caused by the acceleration of massive objects, provides evidence for the validity of this theory.



This updation occurs because gravity is no longer considered as a force but the consequence of what is now called the warping of space-time. To put it simply, gravity is not considered a force in the traditional sense but rather the result of the curvature of space-time. Objects with mass or energy move along the curved paths dictated by the geometry of space-time. The force we perceive as gravity is the effect of objects following these curved paths.



Matter and energy interact with space-time by influencing its curvature. The distribution and movement of matter and energy determine the shape and dynamics of space-time. In turn, the curvature of space-time affects the motion of matter and energy, determining the paths they follow.



The understanding of matter, space, time, and energy is an ongoing pursuit in physics. Scientists aim to develop a unified theory that can explain the interactions and behaviors of these fundamental aspects of the universe. While progress has been made, a complete and comprehensive theory of everything is yet to be achieved.



Taken all these many theories together like, holographic universe, warping of space-time, super string theory, dark matter, dark energy, nature of black holes and so on, science now needs to join all the dots to come to a more comprehensive understanding of the nature of the Cosmos.



Earlier, I mean much earlier, we had Cosmic allegories related to by stories which were used to teach young minds. The understanding then was much different but more cohesive, and definitely, more comprehensive. It is because of these allegorical stories that knowledge didn't disappear altogether.
