Would the Grandfather Paradox Actually Happen?

Post Reply New Topic

If, in your past, you caused a high-impact event like the death of your grandfather and then time-skipped back to your present ... you'd be dead, right? You'd cease to exist the moment ol' Grampy stopped kicking, right? But where would you disappear to if those Heisenberg conservation principles still held?

Think about it.

If what we think of as "time-travel" is actually nothing more than travel between parallel universes, it would be best described not as linear forward/backward motion, but sideways. If by whatever process the temponaut(s) effectively tear a hole in the fabric of space-time (as in Event Horizon), rendering invalid the concept of linear progression ...

What I mean to say is this:

What if I offed my grandfather in the past, went back to the present, and discovered I still had a grandfather? Maybe what I thought was the past was actually a whole other dimension or universe ....

I doubt you can travel backwards in time, because I doubt the past even exists. If it would ever be possible to travel back in time, why haven't anyone from the future visited ut yet?

Watch the episode of Futurama entitled "Roswell that Ends Wells" to find out.

You can't die if you never existed. You have to be alive to die. Killing your grandfather or if he should die would cause a few other things to change as well. It's the butterfly effect.

If there are different solutions to different decisions played out in alternate universe's then that would mean there are too many to count possible involving a few Trillion outcomes dating from the age of the planet itself. Being able to control which universe you could go to would mean the device would have to be accurate 100% and no less. Otherwise you could find yourself getting close to home but never getting there

Let's say the universe I came from has a certain quantum frequency, If I originate fron that universe, would I not also have that same quantum frequency?

The past, as it becomes the present, produces spoor we call artifacts. The remains of the Berlin Wall. The Tower of London, the Pryamids, Stonehenge, etc.

this is a good series of videos, by a physicist who has a lot of respect and is creating a time machine.. he's figured out a way to do it theoretically and is putting it to test.


I would also like to mention that it is speculated that time travel is already possible and is practiced at Area 51.. where else?.. im not speculating from crazy conspiracy loons though im speculating because a man who used to work in the government said so who worked in the black government projects.. wish i remembered his name >.< d'oh!

Physics is for phascists

Suppose time travel was a possibility, but the inventor went into the past and prevented it from being invented because it was trouble. I mean personally I would've bought lotto tickets, but to each his own.

Well thats the paradox, how can you go back in time to kill your grandfather if you were not born.
