no, it is definitely not possible and therefore nothing to worry about when time travelling
no, not a person in the universe
A time paradox or an ontological paradox is something based on time travel that should not have occurred because the past had been changed, rendering it impossible for that event to occur. For instance, John hates his grandfather and goes back in time to kill him, but his parents had not been conceived at the time of his death. Therefore, his parents should not exist, and he should not exist. He could not have gone back in time to kill his grandfather after all. John might discover that the man he had killed was not his grandfather, or the entire universe might collapse as a result of the paradox. There are also some other finite paradoxes, or closed loops that space does not allow to permit.
Sure! Here are a few examples of paradoxes: The liar paradox: "This statement is false." The grandfather paradox: If you went back in time and prevented your grandfather from meeting your grandmother, would you still exist? The unexpected hanging paradox: A judge tells a prisoner he will be hanged at noon on one weekday in the next week, but the hanging will be a surprise - can the prisoner be sure he won't be hanged?
time paradox
Yes, we exist in this universe.
"Does everyone exist or are they just part of the universe that I am creating?" is a question that has been asked in philosophy many times. This varies depending on what you believe. Most people believe that everyone does actually exist.
A time paradox generally refers to a paradox of time travel.The most well-known time paradox is the grandfather paradox. Follow the logic here: If you went back in time and killed your grandfather, then your own father would never have been born and thus you would never have been born. However, if you were never born, then you could never have have gone back in time and killed your grandfather. Therein lies the paradox. What would happen then? Well, since no one's ever traveled through time, it's impossible to know for sure. There are some theories:According to the Back to the Future films, the universe would explode.After killing your grandfather, you would return to the present only to find yourself in a world where you don't exist. Basically, you would be like James Stewart in It's A Wonderful Life.According to the Novikov self-consistency principle, if you went back in time and tried to kill your grandfather, you would find yourself unable to.Another time paradox is the predestination paradox, also known as a "casual loop". This was demonstrated in an episode of The Twilight Zone where a man traveled back in time to determine the cause of a famous fire. While in the past, he accidentally knocked over a kerosene lantern and started the very fire he was trying to determine the cause of. Unlike the grandfather paradox, this does not create a contradiction. In fact, strictly speaking, this is perfectly consistent. However, it's a paradox because it seems to indict that free will doesn't exist or that it's an illusion.An ontological paradox is kind of a version of the predestination paradox. Now, let's say that one day your future self shows up and gives you blueprints to build a time machine. You then build a time machine and travel back in time to give the blueprints to yourself, closing the loop. All this begs the question, where did the blueprints come from in the first place? Well, nowhere, apparently. Perhaps from an earlier timeline.A quick expanation of a time paradox is imagine if you had a time machine, and you went back and killed your grandfather, as a consequence of this your father or mother would never have been conceived, and thus neither will you have been. The paradox comes into play as this, if you were not conceived because you had killed your grandfather, and your parent wasnt born, and you werent born, this means you didnt exist, and If you didnt exist, you werent around to kill your grandfather in the first place, so your parent will have been born, thusly you would have been too. Its all very confusing. Also, imagine someone you love dies,and you go back in time to save them, and you do, the reason you travelled back in time is to save that person, if that person is saved and alive and well, there was no reason to go back in time anyway, so the loop begins again.Also in the new show into the universes with Stephen Hawking a crazy scientis builds a time machine, sets it to be a minute earlier then the present, assembles a gun, goes to the other side of the time machine sees himself assembling the gun and shoots himself through the machine.
If you were to go back in time and kill your parents, it would create a paradox because if your parents were killed before you were born, you would not exist to go back in time in the first place. This type of scenario is often presented in theoretical physics and is known as the grandfather paradox, where altering events in the past can lead to contradictions.
It is an impossibility were something that stops an event which results that made the stopping event not stop it, so the event happens so it makes it stop itself in a never ending cycle,and my guess to what would happen is better than yoursThe below paradox is called a Logical paradox because it deals with truth and contradiction. Many logical paradoxes are variations on Russel's Paradox, a key concept in advanced logic and set theory. Most people know it through the Barber paradox or the Liar's paradox, as seen belowA paradox is simply a statement (or event) that contradicts itself.For example, take the statement 'I always lie'. If this is a true statement (ie the speaker DOES always lie) then the statement must be false because he would be lying when he made the statement! So the true statement is false and vice versa.An event paradox describes an event that again contradicts itself. The most famous is the 'Grandfather paradox': The paradox is this:Suppose a man traveled back in time and killed his biological grandfather before his grandfather met the traveller's grandmother. As a result of this event, one of the traveller's parents (and therefore the traveller himself) would never have been conceived or born. This would suggest that he could not have travelled back in time after all, because he didn't exist having never been born. But if this happened, this in turn implies the grandfather would still be alive, and the traveller would have been conceived, allowing him to travel back in time and kill his grandfather. But if he killed his grandfather..... and so it repeats itself.Thus each possibility seems to contradict itself.
god is no where it is the belief of individual to have the blind faith on the god. God is seeing each and everything that is existing in the world. He is the creater of this whole universe. God doesnot exist anywhere but with the help of his powers he is present at every corner of the universe.
Since aliens do not appear to actually exist, and are probably not criminals if they do exist, there is no way. Someone has to be the first form of intelligent life in the universe, and there is no reason to think it is not us.
The paradox does not exist. Traveling back through times required the exact same energy necessary to create the person independently. So although you have changed the future the existence of the girl remains as she is now independent of the chronological stream that created her.
