lol at kp trolling

And I thought it was some random noob who said that

Like when they built it

Twould only be a paradox if they TOLD themselves how to build them.

Besides, hasn't anybody read The Hitchhiker's Guide to the Galaxy?

Seriously people, all the answers, 30 something yeas old!

it's impossible to go back in time, maybe slow down or speed up someone's perspective of it, but time is only a concept

Dude, he saves the universe in his nightgown

Well it´s sure that we cannot go back in time. Have you heard about grandfther paradox? If you go back in time and kill your grandfather what will hapen? Will you disapear? But if you disapear nobody kills your grandfather, you could born normaly and you can try to kill your grandfather again... im not sure is that endless loop or deadend but still...

Besides that it isn't possible. If you kill him, he is dead, no matter what. And if you dissappear, you will dissappear. And then, there is no loop. Got it?

i wish time travel was possible

So would the entire modern world magically mold around you ceasing to exist?

I actually came up with my own theory of time travel. Who do I talk to about how smart I am about thinking of this s*** first?

Some engineer out there has solved P=NP and it's locked up in an electric eggbeater calibration routine. For every 0x5f375a86 we learn about, there are thousands we never see.

You dont understand. If you werent born, who kills your grandfather?

nobody but then again it loops

or... he gets killed and you disappear at the same time making you both disappear

But I believe that when you are born there comes a time when you die and it will never change

I mean like if you are 45 and you were dead by an accident and someone would travel in time to make that never happen that you would die in another way at the same time.

Like I said before, time travel may be possible but changing the past isn't.
Think of it this way: The entire world would be different from just ONE change. This would cause numerous unsolvable paradoxes, which never happen in real life.
Let's say I tried to go back in time to kill Hitler and prevent the Holocaust. That means 60-something years ago, my future self was trying to kill Hitler but failed. Meaning when I (hypothetically) try, I will fail as I did 60 years ago.

Actually, that means that time travel itself is impossible. What if when the time comes I were to decide NOT to? That would mean a small part of the entire universe was just changed, and as I explained, that's not possible.
