When you start thinking about time travel, you pretty quickly get to the central and most difficult question: can you change the past? In short, he dies. And this is the essence of the Grandfather Paradox. The laws of physics are local, each step following on from the step before, and yet, looked at globally, the result seems contradictory. How ca...Physi...

Eventually the poison seeps through the system and the victim is gradually transformed into a Varga. No, it’s the whole turning into a plant bit that’s the problem. Plants and animals have fundamental differ...
