Gravity, Antigravity, and Gravitational Shielding Along with Related Prospective Viewpoints and Possible Practical Applications: An Overview

Gravity, antigravity, and gravitational shielding are all interconnected topics. However, we find very few papers that address this interconnected topic from a global perspective. Gravity and gravity-related topics are one of the most fascinating areas of study for scientists, and they will continue to be so for many years to come. In terms of the gravity concept, Einstein's General Relativity equation is brilliant. However, the apparent contradiction between quantum mechanics and general relativity has yet to be resolved. Edwin Hubble reported on the expanding universe in a classic article published in 1929. The antigravity effect has been demonstrated by his discovery. Many researchers have reported on gravitational shielding devices. At this point, we anticipate the development of more powerful gravitational shielding devices in the near future. Several prospective and practical concepts and ideas are presented in this review article, including a cosmic elevator, the use of sky-space for vehicles, and a modified equation for gravity.
