I was watching Voyagers Timeless and I was wondering what happens to the present if the past is altered, if it merely fades away from existance from the POV of those in the present?
It's just that I often assumed that if you in the present send a signal into the past to change a certain event, no physical time travelling is done, then all you do is create a new time line/universe from that past point and the present you live in still continues on, unless of course you have some techno babble time device that protects you from the change in the timeline and alters everything around you. But the way it's portrayed here is that Harry and Chakotay are basically wiping out everyone and everything that exists in there timeline from existance.
How can anyone really make a decision like that even though from the pasts perspective they now no longer exist but should still do in the present?
