‘Back to future’ is a piece of shit. The worst thing about the time travel with past altering act is, you lose your will, the freedom, forever. Dark came up with one of the possibilities of time travel, where the past can not die with future alive. The same scenario was different in the time travel of endgame, where the past dies and future lives. Yes, the death of nebula. The Most common thing find among all the time travelling stuff is Particle physics. E.G. Pim particles, God particles, Uranium. Time is Radioactive. Insane. Wanna get over -_-
