Our unique, interactive simulation immerses you in the core principles of Einstein’s theory of general relativity. Embark on an exhilarating journey where you wield the power to manipulate mass, exploring the curvature of not just three spatial dimensions, but also time itself, shaping the very fabric of reality with your every move! Designed by experts in theoretical physics at the University of Illinois Urbana-Champaign, this simulation vividly showcases Einstein's greatest achievement, making it easily understandable and accessible. Our goal is to educate players about the effects of gravity and look at the attractive phenomenon in a whole new way. Experience the thrill of having control over the curvature of spacetime!
