“Time loops have a significant impact on the principle of causality. On the relationship of cause and effect. As long as a wormhole exists, there is a closed time loop. Inside it, everything is mutually dependent. The past doesn’t just influence the future. The future also influences the past. It’s like the question of the chicken and the egg. We can no longer say which of the two came first. Everything is interconnected.” From “Dark” (Netflix, 2017)
