Yes I realize that, we wouldn't know it if history had changed, onkt the person who did the changing would know that.

the answer to your question lies in the concept of parallel dimensions. when you go back in time (& space) you actually are not going backwards but you are going in another dimension. after you are in that dimension whatever you do does not effect anything that has happened in the past or will happen in the future. so nobody can can change the history or plan the future.
Note: like time travel by humans is theoratical, the concept of parallel dimensions ( universes) is also theoratical.

Yes, this is a big problem in time travel. What effects can changing the past have? Will it change the the whole history or was it predestined to happen so?

There is one paradox about changing the past, called Grandfather paradox. It's more or less alternative way to kill yourself :) Several movies have shown how it's possible to change future by changing the past. And I think it was the best shown in "The butterfly effect".
Probably if we would try to change something in history, major changed would occur. Much bigger than we expect. It's like chaos theory states "minor changed in input make major changes in output". Consider history the "input" and present/future the "output"

The repercussions of a person even entering the past could be so huge that it boggles the mind. That is why I can't see the possibility of past time travel unless we reach the speed of light.At that point, time ceases to exist,and all things are seen at once.

Travelling in time would be like surfing the net in google.
You can go back and forward, but only to your last choices.
