  "abstract": "In this paper, the Lorentz transformation of entangled Bell states seen by a moving observer is studied. The calculated Bell observable for 4 joint measurements turns out to give a universal value, $<\\hat{a}\\otimes\\vec{b}>+<\\hat{a}\\otimes\\vec{b}'>+\\lang le\\hat{a}'\\otimes\\vec{b}> -<\\hat{a}'\\otimes\\vec{b}'>=\\frac{2}{\\sqrt{2-\\beta^2}}(1+\\sqrt{1-\\be ta^2})$, where $\\hat{a}, \\hat{b}$ are the relativistic spin observables derived from the Pauli-Lubanski pseudo vector and $\\beta=\\frac{v}{c}$. We found that the degree of violation of the Bell's inequality is decreasing with increasing velocity of the observer and the Bell's inequality is satisfied in the ultra-relativistic limit where the boost speed reaches the speed of light.",
