How Close Are We to Building Force Fields?

The video explores the concept of force fields, a staple of science fiction, and their potential real-world applications. It discusses current research efforts to develop force fields for military purposes, focusing on two main types: those that block matter and those that block radiation. The UK's Defense Science and Technology Laboratory is working on 'electric armor' to repel missiles, while theoretical research suggests plasma could block radiation. However, challenges remain, such as the inability to block both matter and radiation simultaneously without impairing visibility. The video concludes that while comprehensive force fields are still a distant goal, ongoing research may eventually make them a reality.

What challenges are associated with creating a plasma force field that can block lasers?

What advancements are needed to develop a force field that could block both matter and radiation effectively?
