Abstract
This research work investigates the possibility of shielding gravity. The ultimate purpose of this work is to understand the reality behind the concept of Gravitational Shielding (GS) and time dilation. Since the 19th century, scientists have tried to arrive at an understanding of GS via the use of various experiments. Unfortunately, some experiments failed to prove the existence of gravitational shielding, whereas some results proclaimed the possibility of attaining GS. The original phenomenon exhibited by nature cannot easily be understood, but some experiments have demonstrated that the answer may lie behind the mysterious GS. If GS is proved, then in the future, it would be possible to travel across black holes by defying gravity or through any bigger mass having high gravitational field. To unravel the mystery of GS, this work investigates the history of GS and considers the future vision of technologically advanced spacecraft or other warp drive mechanisms with appropriate gravitational shielding. Though the problem is very complex, this research work tries to come to a deeper understanding and explanation of the complexity involved in achieving gravitational shielding.

Newton assumed that the gravity insulation cannot be made by the outer layer of shell with its interior
Could this solution lead to exotic physical phenomena like wormholes, time travel and warp drive? Consider the following: The Casimir effect between the attractive Casimir forces between two plates of area A separated by distance L can be calculated as in Equation (2): F =
According to the solution obtained from the case study, final time deviates from original time by very few seconds, even for higher amount of gravitational shielding
Summary
Newton assumed that the gravity insulation cannot be made by the outer layer of shell with its interior. Scientists have since furnished this gravitational shielding problem with several theoretical and empirical evidences. One such piece of evidence is provided by Italian scientist. Majorana (1999), who observed that the weight of a body decreases when it is subjected to thick shield of mercury [10]. He formulated a law as in Equation (1) (Majorana, 1999) to depict the gravitational field outside the shell having the absorption coefficient when the material is placed at centre of shell [11]. A number of researchers claimed that the weight of test masses with various materials varies using various excitations
