About time-travel

Hello, my name is Alex.

 

 

Lets assume that we have a time machine. We are going in time from p.1 to p.2. There is nothing for us (who traveling) between 1 and 2. And here are the questions:

1. If “World line” should be continuous and shouldn’t break then [0,1] should be changed also. So, can we know anything about the past where we came from?
2. If we assume that the future is set and world just going his way. Can the time travel accident change the normal course of time and, for example, accelerate the evolution of live?

It’s just some logical questions. Thank you for your time.

I suppose that if you are making up things like that, then the answers can be whatever you want. So the answers to Q1 and Q2 are yes and/or no.
