GAURI's BLOG - Grandfather Paradox
WHAT IF YOU TIME TRAVELLED IN THE PAST AND KILLED YOUR GRANDFATHER?
Now to solve this paradox, I referred the articles of various mathematicians and physicists, by putting them all together in a simple language here I present my next blog related to time.
First of all, time travel would never allow the possibility of self-annihilation. (making your existence disappear from the past, present, and future) . then what would happen if you do so?
BRANCHING TIME TRAVEL: according to the philosophers Nuel Belnap and David Deutsch, when you travel back in time you don’t actually travel in your original timeline, but in an alternate timeline of the alternate universe just like yours. And when you point a gun towards your grandfather and shot it, you are killing your identical grandfather from that identical universe, not yours. And then after his death, your father wouldn’t be born in that specific alternate universe there, and neither would you. Hence you would just prevent that universe’s version of you being born.
But from this solution, we didn’t get satisfying answers. The second solution given by David lewis was, time travel would not give someone the ability to kill their own grandfather because doing so would be impossible—essentially because they’d be predestined not to do so. He says we cannot affect the things that already happened as that would never meant to be happen. Philosopher maulin says “It's actually more difficult than you think to come up with a situation where there are no consistent solutions,” unless we create a time machine and found it ourselves.
And if you created one, here are my coordinates, welcome time travellers.

Exited for next one😍
If our own grandpa get killed in same time line (which is possible a per theory) we do not exist at the same moment & then there will be new alternate timeline reality created.
So scientist belives these reality existing parallely, sometimes our individual decisions make it different & gives diff destiny.
I am a Dev and would take situation like a Git repo. If you traversing a data structure backwords, ideally you are not supposed to make a permanent change (a change that creates history/a new data point). If you do so: you have to branch out.
