Within the vast expanse of space, the Holtzmann Shield serves as a mobile force field capable of shielding individual soldiers in combat. This shield, generated by a device attached to a belt, can divert fast-moving projectiles away from the wearer, although slow-moving objects like combat knives can breach the barrier.
Creating such force fields presents a significant challenge in reality. Gravity, electromagnetism, and the strong and weak nuclear forces are the four fundamental forces in nature. While gravity is too feeble to function as a local force field, the nuclear force is robust but limited to the atomic nucleus.
Physicist Professor Jim Al Khaliliand researchers at the University of Surrey are exploring the possibilities of constructing force fields based on electromagnetism, a force more potent than gravity and with a longer reach compared to the nuclear force. However, this force only affects charged objects, necessitating the charging of detected flying objects.
One proposed method involves bombarding objects with positron beams, which are antimatter particles with the same mass as electrons but opposite charge. The annihilation of positrons and electrons can potentially charge and deflect incoming projectiles, offering a route to building force fields.
Though theoretically possible, this technology is likely a distant prospect, possibly not materializing for another 20,000 years. In the meantime, research is underway on electric armor for tanks, which replaces heavy steel plates with energized thin metal plates separated by insulation to store a significant charge. This innovative armor system improves efficiency and reduces weight, enhancing the agility of armored vehicles.
