Is your grandfather still alive? if you killed him tomorrow would you cease to exist?

I presumed she meant, that my grandfather was killed, before my father had been conceived by my grandfather and -mother.

But it's a paradox, isn't it?

You kill your grandfather, so you cease to exist, so then nobody could've killed your grandfather. So is your grandfather still alive? That's what this thread is for

But if you didn't exist then who killed your grandfather?

OMG sleeping is mini time travel

[lostalex]

What if the time machine has a glitch and you end up just constantly being taken back in time just a split second like when a CD get's stuck and starts making that annoying sound... does that mean you can live forever?... the same split second for all eternity.

Did you watch Interstellar?

The "time travel" in interstellar is (effectively) the same principle... The characters don't travel through time more quickly than anyone else, everyone else just keeps aging and time moves on around them while they are "frozen" (moving very, very slowly in relativity to those outside the time distortion)

Is'nt there a part in Interstellar where one of them stays on the ship and a team go down to the surface of a planet but because the planet is so close to a black hole time travels much faster for them.When they get back up to the ship the guy who stayed behind has aged like 20 years or something?

Yeah time distortions are a huge part of the film, there's that one and

Spoiler:

also another involving the black hole at the end that passes another 50 or 60 years or something so that the guy is still the same age at the end of the film when he gets home but his daughter is 90+ and they've built space stations and loads of other tech using the information he managed to send to them

Spoiler:

Oh yeah!He meets his daughter again on a space station and she's really old

Yes!That was a very clever film.Really enjoyed it.

There really is no 'right' time in the universe is there?Everything in the universe travels at its own time frame depending on the speed it's traveling.If an object is in close proximity to another object(like us to the sun and the sun to the galaxy) etc then it travels faster due to its orbit and the faster an object travels then the slower time around it goes.Is that right?That's my basic understanding.

Also add on top of that the fact that everything is traveling through space.The galaxy's etc which also has an effect on time.

Time really is relative.

this is the best explanation i think.

the only way to travel back in time would be to travel faster than the expansion of the universe itself, because the only real measure of time is how quickly;y the universe is expanding, but you can never travel so quickly towards the center of the universe that you could see the beginning of the universe, because it's already happened. The beginning of the universe has already happened, and really we are just watching the consequences of that at varying speeds.

Well yeah that sounds logical.Except there are theories that if you could bend time like folding a piece of paper then maybe instead of following the piece of paper(time) round the bend you could travel directly between the two sides(points in time),Maybe by going through a worm hole(if they exist) bypassing the bend(the timeline) and traveling back to a point that has already happened(the past).
I think it's unlikely to ever be possible but who am i?

[lostalex]

also there is the idea of re-incarnation...if re-incarnation is real then you would still exist no matter who your grandfather was, because your soul would still be put into a body, it's not about genetics if you believe in re-incarnation.

you cant go back in time is the actual answer

[Kizzy]

If the concept of time shifts and slips in space and time/dimensions are so acceptable then why not the idea of shuffling off the mortal coil... to another when we die?

kizzy when you die nothing is going to happen, stop reaching

[BBfanUSA]

Personally I believe in the multiverse theory because you'd could be creating a time paradox by killing your grandfather, if he died before your parent was conceived, then you would cease to exist, therefore you're unable to kill your grandfather, thus bringing him back to life

[Jessica.]

You can't guess anything exists unless there is proof to be honest. You can hope all you want but factually it doesn't exist.

No one needs to watch The Butterfly Effect, it's awful!

Plus irrelevant to the grandfather paradox because in the Butterfly Effect rules you timetravel within your own consciousness and so (in that example) the furthest back you could go is being a fetus. I guess you could maybe hang yourself on the umbilical cord as a sort of self-abortion...

[If you went back in time and killed your grandfather, what would happen?]


We are unable to travel back in time
but with high powered faster travel
we will jump ahead in time

[Jamie89]

I suppose if you go back to kill your grandfather before you were born, then by definition of the scenario where you are in the past, you are already living in a world where it is possible to exist without having been born. And so killing him shouldn't make any difference to you in terms of the 'if he's dead you would never be born' problem. If you catch my drift?

Alternatively if you want to kill your grandfather AND travel through time without igniting the grandfather paradox, you could just travel to last week and kill him (assuming he was alive last week).
