Back In Time
I was thinking about time travel and I was so confused on how going BACK in time and changing something would work. If somebody was to travel back in time and lets say this was a huge event which was broadcasted. So, if that person went back in time and lets say they stopped WWI, would we feel time going back or would we have already been living as if WWI never existed?
People say changing the past can lead to a different future but how would we notice it? Wouldn't we already be living in the 'new' future? So how would we notice this. I personally think its a question with multiple possible answers but what do you guys think?
If the past was to be changed, would we see the change or would we already be living in the changed future?

It's all hypothetical, but it would solve the paradox you proposed.
An alternative would be that if one goes back in time it's already in the past, so it already happened and is in effect. Nothing would change. Going back in the past and changing the future drastically would be physically impossible.
The problem with that is that it requires a strict deterministic universe, and many people don't like that idea because it contradicts free will.
Determinism is the idea that every single event has very specific conditions, meaning that the universe in its current state has to be as it is for any events in the future to happen. The universe as it is is the condition for strictly logical events in the future to happen etc.
That means that everything is already written in stone and nothing can be changed at all ever.

How are you?
I don't think that time is a tangible substance and therefore cannot be traveled through. Even the slightest alteration to a spec of dust in the past can potentially lead to a drastic change in the future making it nearly impossible. At least the theory of the spacetime continuum states something similar to this. Bending space isn't possible making time travel utterly implausible and therefore doubtful that there are multiple versions of us in different dimensions. I don't think humans were meant to comprehend the relationship between space and time either. We can't quite wrap our minds around it and that's were answers to life and such will come from.
Buy me food and tell me I'm cute.
