What is your answer to this classic time paradox?

Okay, imagine this situation. One day, a man invents a time machine, goes back in time to the time of his parents and murders his mother. Because his mother dies, he isn%26#039;t born, so he ceases to exist. But when he ceases to exist, his mother is never killed, and so he is born again, to kill his mother, and not to at the same time.





What do you think would be the result? Would this be an infinite time loop? Would going back in time in the first place cause an infinite time loop?





I%26#039;ve thought up the theory that every change you make in the past doesn%26#039;t affect the present and future, because it technically already happened. But this kind of paradox just won%26#039;t be solved. Help me!|||Try this, there is no start or end in time, so it must be running through a loop. If you break out of that loop you will create another loop, both loops will be running through time but they


will be separated from one another. If you try to enter an existing loop you will just create another.


If the loops are created at the point when you disrupt another, by killing you own mother you will just create another loop with a different future.


This is just a theory of mine , if you want to, you can break it apart


and we can try to come up with a solution.|||My answer is you should focus your mental energies on something which has at least a chance in hades of doing you some good.





Here%26#039;s a paradox. A man goes back in time, looks himself up and slaps his young self a few times for not studying harder, causing him to have to manufacture his time machine out of fryers, refrigerator parts and paper hats. But then, he never ends up working at the place where he originally built his time mac_chine.|||That question just about confused me to death.





It is also why there is no such thing as time travel, and there never should be.|||a classic but not possible. How ever there is more then one time line we live in one among infinity. have you ever thought something said like if Al Gore won the 2000 elections well in another time line that all happened. When you travel through time you make another time line so there is no paradox.





But if we send people back through time to prevent a tragic event such as 9/11 nothing will be fixed because we are still in the same time line and the people who went back through time would have prevented it but they are in another time line.





A theory based off of Stephen Hawking lectures and Einstein%26#039;s theory of relativity|||The cycles of A and B and A goes on many times, but eventually damps out. So, no A , no B. This paradox can be solved.|||ok, lets suppose that he was conceived on a tuesday.


If he goes back into the past on monday, the day before, and kills one of his parents, then as you said he would cease to exist.


Then simply he would not be born and one of his parents would die and life would continue like that and the fact that he time-travelled in the future would never happen. I dont think that a loop would be created.


However, I dont think that time-travelling is possible and no, you cant change the future or the past.|||The question seems to me to be the mental and logical equivalent of the mobious strip, or better, Escher%26#039;s illogical reverse stairways.





Can God make a rock so big He can%26#039;t pick it up?





While our minds can try to spin out an answer based upon the logical inconsistencies, at the end of the day it is a completely academic exercise until you actually deal with the original postulate....%26quot;One day, a man invents a time machine....%26quot;





Since you%26#039;ve placed this in the Physics section, you still need to first address Einstein%26#039;s General and Special theories before you can cross that barrier.





Best to you.|||The answer is, man cannot travel back in time.|||My opinion: Man goes back in time, kills mother, continues life in that time, dies of old age or whatever. End of story.
