or will a new future be created, and our current future stay the same?

Depends on how dramatic the change is. But things will change, the whole world though? Dont know. Like I said, it depends on the change. But little things can change things too...kinda like a butterfly effect.

The only way to resolve time paradoxes is with a Theory of Many Universes, which an alternate reality is created for exery possiblity. It is also possible that parts of these Universes overlap in areas that they are the same.
Without this, time travel becomes entirely too complicated, to the point of being simply impossible. However contemporary science seems to indicate that it may be possible but that it is simply our of reach. If we were to move at speeds greater than light speed, for example, we would be moving backwards in time.
It is hard to imagine a universe in which I could go back in time and kill my father, so I must assume this is now how the universe works until there is a reason to believe otherwise.
However, it is also possible that the only controlable method of time travel is posative fourth dimentional and that negative 4D motion is simply not possible. Evidence suggests that time is rather like a river, with a current generaly moving things forwards but with swirls and eddies, caused by abnormalitys, common as well. Not like a straight line that continuously ticks forward. If time is fluid, then that leaves a lot of possibility.

a new parallel universe is created with different scene, but the current universe stay the same. but can you imagine how big the energy needed to create a new universe? infinite. this is the number of energy you need to travel back into time since to do this you have to travel faster than the speed of light. And nothing that have mass can do this, because the closer you reach the speed of light, the more mass you gained, and more energy needed. when your speedometer shows around 300.000 km/s, your mass is infinite.

If you could go back in time then There are to schools of thought. First is you cant change anything in the past because if you could goback in time you were already there and whatever you did has been done(whew!) If you tried to assasinate hitler for example, something would prevent you from doing so. Now if you could back back and change something the only way around the paradox (of you killing your grandfather before he married your grandmother then you would no longer exist but since you exist then how did you go back and kill him) is you would be traveling to an alternate time line. In the timeline you came from your grandfather never was killed --thus you exist--the timeline you go to you kill him so that you were never born on that time line, but since your from a dif time line you still exist. timelines would be alternate realites in a nutshell.

Each moment in time only happens once and in a continuation. You could possibly travel back in time, but you would have already been there in the first place. This is the 'you can't kill your own grandfather' rule. You could travel back in time and try to kill your grandfather, but because you do in fact exist now, you therefore were not successful in your attempt. So no, you cannot change the present by traveling back in time. I learned that in Philosophy 101 in college.

Some scientists believ this violates heisenbergs uncertainty principle. If you travel back to try to change some very well known event, say the assination of Kenedy, that event is so well known, or localized that the energy needed to change it would be almost infinite.

You can not travel back in time, there is no past, there are only records of the past. There is only, NOW. As events take place they become the ashes known as the past and events do not evolve into the future, there is no future.

What you just described is called the time paradox.
And to answer your question, if you mess witht the past then your future never happen therefor you didn't mess with the past and your future is the same as always.

Such problematic questions hint at why time travel is not really possible. It violates neccessary realities of linearity and causality.
Even tiny disruptions could have unforseen consequences.
Imagine that you travel back and somehow, intentionally or not, change the timeline such that your time machine is never invented.
Then how did you get there?

I would say yes. Things could have been changed already but we never know.
