Force A Grand Unified Theory that allows for the combination of the electroweak interaction with the strong force is held out as a possibility with candidate theories such as supersymmetry proposed to accommodate some of the outstanding unsolved problems in physics. Physicists are still attempting to develop self-consistent unification models that would combine all four fundamental interactions into a theory of everything. Einstein tried and failed at this endeavor, but currently the most popular approach to answering this question is string theory. What we now call gravity was not identified as a universal force until the work of Isaac Newton. Before
Unified Task Force Unified Task Force The Unified Task Force (UNITAF) was a US-led, United Nations-sanctioned multinational force, which operated in Somalia between . A United States initiative (code-named Operation Restore Hope), UNITAF was charged with carrying out United Nations Security Council Resolution 794 to create a protected environment for conducting humanitarian operations in the southern half of the country.
