One question I have always been wondering is if it is possible to travel through time at will. I know the old paradox of going back in time and killing your mother before you were born or even conceived could it be possible? If it is how you could have gone back in time to kill your mother before you were created or took your first breath? It is an interesting paradox but I don’t know if it is possible to travel in time I think it goes against the laws of physics. The link below may answer or raise more questions to me it is a little too wordy to understand exactly what is going on. After reading it a few times I caught what it was trying to say.

There are multiple theories on time that ultimately rule time travel out as a possibility.

However, there are a couple theories that don't completely discount time travel as an impossibility.

Assuming at ever decision point in time all possibilities play out in an alternate universe, it would be entirely possible to go back to a point in time where you were to be born and kill yourself only to find that you do in fact still exist as you're "universe" was ultimately never altered. In the end, you simply created an additional Universe or simply played a role in the creation of an alternate universe before you were even born.

Then again, if we assume the Universe to be a "perfect construct", it's entirely possible that if time travel were possible any anomaly in time created by someone from the future altering the past may simply create an alternative "time line" in which you'd return to but not be removed from. There would ultimately be a single "line", but an altered "line" upon any dramatic shifting of events.

However, before anyone starts saying what is not possible.. you've gotta consider how many things people said were impossible only to be "conquered" sometime later. If you go back in time far enough and tell the people that one day Humanity would land a craft on the moon and man would walk on the moon, you could very well be put to death.

It'll be interesting to see what the Universe looks like when/if Humanity ever gets a full grasp on the concept of Time and Space.

I agree with you in the fact that if you do go back in time to till your mother that you could return to a time when you left and actually be alive in that time. For in many ways you have already been born and have lived a portion of your life to a time when you are able to return to the past to do anything. However I do believe that if you do go back in time you will create a paradox which is a cool thing on its own. I do believe that if it is possible to travel back in time no matter what you do there has be to a set of consequences for your actions that at the time of going back you could not know. These consequences could only be known once you return as that is when the damage would be done. For all we know you could go back in time and kill your mom only to find out that 3 years later your father married someone else and they happened to have you anyway. Perhaps you would be a little different but maybe you wouldn’t be. Perhaps you were always meant to be what you are and nothing can change that.

As far as parallel time lines go that seems to me to be a different subject entirely. I have always wondered what if I was to have done certain small things differently what would my live be like now. For example what if I were to sleep in one day rather than getting up early. What would that small change do to the rest of my life? Could it be that on that particular day I made the choice to sleep in but if I were to get up I would have gone to the store and picked up a winning lottery ticket? Or perhaps sleeping in I had a dream for a really good business idea and that was the better of the two options. I definitely believe that we all make out lives out to be what we want them to be. I don’t believe there is some higher power making the choices. Some people may believe that our lives and all of our actions are pre destined and already laid out for us. If this is true then there is no point in worrying about anything because everything will unfold as it was meant to from the time of creation. I am unable to believe in this because I find myself to have so many choices that to me feel as if I am making them on my own and nothing is guiding me or making the decisions for me. This is my life and I believe that it is mine to lead how I see fit and of course mistakes will be made along the way but those have to be made to learn. To me there would be no reason to make mistakes if life was all set out for us because at this point in humanity we have been around so much most of human error would be fixed by the higher power. I know this does step out of the bounds of time travel a little bit but fate and pre destination plays a role in how time unfolds if you have a belief in it that is.

A Paradox is entirely possible. However, if time holds even a remote property of linearity, what you've done in the past is still in your future despite traveling back into your past. That also means that traveling back into the present would also be in your future therefore following your portion of linear time.



The Butterfly Effect. A simple and small action in one area of the world can have great consequences for the rest of the world. For example, a Butterfly flaps it's wings over on the Eastern Coast of Asia and the Western Coast of North America gets hit with a Tsunami.

The simple act of traveling back in time, short of being contained within a "phased bubble(physically, chronologically)", you may very well destroy some piece of grass or contaminate the grass causing some dramatic change in time down the line.



An interesting point, however you are who you are because the one sperm from your father and the one egg from your mother combined and began a reaction which in turn began the process of life that in 9 months becomes known as you. The odds of that happening is insane. The odds of your father giving you life after your mother donated your egg is insane to the power of insane. Therefore, once you've killed yourself off by eliminating the source of one half(I'm not 100% sure about how the genetic material of mother and father is combined.. so one half here simply refers to the egg) of your being.. you'd have to win the lottery every day for an entire life time to reach the odds of yourself being born without your mother.



Actually, it's still on the subject of time travel.. just a different understanding of the effects of time travel on the events known as your present if you go back and do something that will affect your future.

It's entirely possible that no matter what you do in time, you'll always return to your "space-time" and any "changed" event would have played out in an "alternate dimension". You being who you are based on the actions you took, you may never be able to witness a different time line based on changes due entirely to traveling back in time. You would in fact need to find a method of traveling inter-dimensionally in order to experience these "changes" you've made to time.



This, on the other hand, is an entirely different topic. lol

Simple answer to a complex question: Of course it is.Science has busted so many thought unbreakable laws over the years, it need not stop at the time travel issue as well.
