1.Why doc strange not use time gem to revival tony, like thanos revival the vision to take mind gem ?
2. The story tell that to make time travel, need 1 pym particel to go and back, in film the future nebula only have 1 pym particel and thanos take it and sent old nebula to the future, after that bring thanos and his army to future.. The question is thanos can duplicate pym particel??
