Relativity makes my head hurt. All that said, there does seem to be a pretty concrete takeaway thats rooted in some widely accepted ideas from theoretical physics. We have not yet invented a time machine. If and when we do, well enter a new era of time travel. We will not, however be able to go any further back in time than when that machine was built. Thats all assuming that this hypothetical time machine can actually go back in time. Again, thats really difficult. gizmodo/a-brief-history-of-scientists-hunting-for-time-traveler-1641272404
