👉An event with no beginning and ending is called a #loop. Even though it seems possible to travel back in time back to past .There are temporal paradoxes that would seem not possible to travel back in time .Let's make a quick review through the common temporal paradoxes.

Grandfather paradox:
👉Suppose, you made a sincere request for a sports bike to your family. Everyone agreed except your grandfather. Then you became extremely angry and you got the instinct to kill him. And you used your genius mind and created a time machine and travelled to the past at
that time when your grandpa was young, and you killed him.

👉It seems you will feel satisfied and happy because you killed your future
villain. But the main twist is that how you killed him?🤔 Because you killed
your grandfather even before your father was born. So it means you are not born. 🙄Which further implies you didn’t create a Time machine,which means you didn’t kill grandfather. And in the end, it means you don’t even exist and grandfather is still alive.As your grandfather is alive, he got married, and then your father was
born, and then you came into existent. Now you desired to have a
sports bike......

👉it sounds funny, but you have created an infinity loop which won’t end. While this loop is a time paradox, and this time paradox is termed as Grandfather Paradox.

Bootstrap paradox:
👉Now imagine, you heard a knock on your door. There was a parcel lying on the floor. You opened it and found a procedure and formula to build a time machine. After your perseverance, you created a time machine.Then to test it you travelled into the past and gifted the procedure and formula to your younger self. Then that younger self again created the time machine and gifted it to its younger self.So this creates an infinite loop. So basically who kept that parcel at the beginning? This time paradox is known as a Bootstrap paradox.

Predestination paradox:

👉Now Imagine, you are the man and created a time machine and travelled into the past. There you met a lady (who is going to be your mother in future) and fell in love with her. Years later, you both got married and had a baby. This baby is going to be the man who actually travelled back in time in the first place.
👉In simple words, you and your mother got married and had a son, and ultimately you found that the son is you! (It’s like, A marries B, and have so A). This paradox is known as predestination paradox.And finally,

Twin paradox:
👉Suppose imagine, ‘A’ and ‘B’ are twin brothers and say ‘B’ leaves the planet Earth and travels in space at high speed. And after 10 years B returns to Earth. Will ‘A’ and ‘B’ be of the same age? So the answer is no?

👌I need you to answer the last question with brief explanation on the comment box.🙏
