If someone did change the past in someway or the other, it would make our present uncertain. An uncertain present is really hard to imagine. About travelling to future, that's always possible. We all travel towards future at a slow pace as we grow in age. The thing we are interested in is how to speed up or slow down this process. Time is like a river. At some places it flows faster, while in some places it flows slower. It is a simple theory (I honestly don't know how it was proved) that the time around a particle of high mass moves slow in time. A simple demonstration of it can be seen on our earth itself. If we stand near a pyramid, we'll observe the activities going on away from pyramid slightly faster. That is the place where the theory of slow time around black hole originates. Black hole has very high mass and it can throw us slow in time considerably if we manage to revolve around it surpassing its super high gravity..
It theory, if you would be able to get to the past and you would change something, then you wouldn't notice because this thing happened already.
You all take time as a straight line, but if time travel is possible, you have to re-create the wheel, time will be made from millions of little circles. I suggest reading The Hitchhikers Guide last episode (fifth one) you will understand what I mean.
I was trying to understand similar concept for 2 years (I knew how it is, but the result is so abstract, that you have to really focus on it... basically, i was thinking how endless looks and how I could make a copy of universe, I have actually succeeded)
Other, more easy to understand theory would be, that every your decision creates a whole new universe. Something like a copy of this one, but with different decisions, for example, there is a universe where I never joined HC and another universe where I never played an instrument and universe where I didn't do either of these... OFC there again, the time is in a straight line...
Staff will never ever ask you for your personal information.
We know everything about you anyway.
