do you think it is possible? how? how do we handle time paradoxes(killing your grandfather)?

Time paradoxes won't exist. The mere fact that you were born already indicates you didn't manage to kill your grandfather.

Anyways, you can't go back in time, only forward.
It's all to do with acceleration, but I'm too tired to be bothered explaining it.

Actually it is possible to travel back in time. And you can do it.

All you have to do is to go straight to your local library and ask for
copies of the classics, then stop by the supermarket and buy lots of
things you like to snack, and then spend a whole weekend in your
room going through all the marvels of literature.

Pirate ships, air balloon trips around the globe, corageous battles in
ancient greece, breathe taking intrigues in medieval Europe, hunting
lions in the dawn of the XX century, building a railroad from Cape Town
to Cairo, buy souls with Gogol in Russia, and much more... all that
can take you to a marvelous travel in time that will change your
life forever.

I see no point in wondering how to travel in time if it can be already done.

The same way I feel of little use to invest millions in searching for life
in the outer space... when we have life here that needs to be protected.

This post, my dear fellows, was my sweetness attack of the month.

Thanks for watching.

Love all. Serve all.

Time travel doesn't seem likely -- for now, we have to be content with bad sci-fi movie plots.

All you have to do is spin around in a circle real fast. Clockwise takes you forward in time, counter-clockwise takes you back in time.

YOu guys are all a bunch of Pricks! ha ha ha.

I think Im travle backwards Perhaps might be true? But I really don't think that it is likely. Do you really think that if people could go back in time we would have heard of it by now? Do you not think that people from the future would come back and either try to help us out and give us technology or try to right so major wrongs like the world wars, perhaps kill hitler while he's taking a dump in high school with a ray gun. Or a t the other side of the spectrum don't you think that some one from the future would have at least come back at some point and try to rule the world as we know it? I really think its unlikely but I guess if anything can be possible... I guess

But as far as if you would go back in time and kill you grandfather before you birth would you still exist.... Yes, you would not evaporate like the terminator at that point of killing your grand father you infact would create a split or a fork in the time line and would merely go down that path instead of the original. Which would mean if time travel backward were possible and people could create such a device and use it the time line could not be a straight line or even 2 demensional. I belive that it would kind of look like a sphere cut in half and the center of the sphere would be the begining it would only be a half sphere I'm arguing because if time has a origin it probably would be impossible to go infront of it. and from that starting point all possiple time lines could branch off of it like a tree almost but their would an infinite amont of possiblities probably most of them being almost Identical to each other but at some point changing slightly.
So inconclusion If you killed you grandfather before you were born you would still continue to exist and you would creat a slightly different paralell existance.

And that's Hank Reardens Theory on time travel

While in said library, pick up a dictionary for Seitse.

The possibility of time travel is debatable. But a spacecraft which can travel at near-light speed will unlikely be seen in the 21st century. Even if there is such a spacecraft, people who set off on time travel may not always find what they are looking for at the end of their destination.

Forwards time travel is possible a la special relativity and a superfast spacecraft.

Backwards time travel is possible in theory via general relativity and wormholes - requiring some pretty exotic physics to construct however. The practicality of course hinges on the paradoxes you mention.

Some have suggested that time travel to the past will not be possible physically because of the paradox nature - this is sometimes known as the Chronology Protection Conjecture - and has had such luminaries as Arthur C. Clarke and Stephen Hawking amongst supporters.
Others have suggested that backward time travel would throw you into alternate universes, where you could easily kill your grandfather and still exist (having had your actual grandfather still alive in your actual universe).

I think the most we can know at this stage is that the notion of time travel makes for some pretty interesting stories.
I urge people to take a look at Robert Heinlein's short story All you zombies for a wild take on the paradox issue.

That is one of the greatest short stories ever.

Actually, that has been explained via parallel universes. Each time you go back in time, you effectively cause a parallel universe to branch off. Kill your grandfather and you have one universe where your grandfather exists (the one you are originally from) and another parallel universe where he is dead (the parallel universe you have just branched off). This would mean that the branched off universe you have created means you will exist in limbo. This world you would have just appeared using a time machine with no apparent explaination for your existance.

Using this theory, there are basically infinite parallel universes. Every decision in history can determine future outcomes all the time.

Forward time travel has proven to be possible. We are going forward all the time, just that the rate of going forward can be changed (time dilation).

Should have read this before my last post. I have read about the Chronology Protection Conjecture before but parallel universes seem more plausible to me. Maybe one day we will find out. 🙂

Maybe.
I like the CPC for it's simple call to evidence. We don't see any evidence of time travellers from the future, hence, time trave4l to the past will never be possible in practice.
It requires no additional physics and no philosophical headaches - such as parallel universes suggest.

damn it, i was going to say that 😉. anyway here is something more on this matter

if we take for true what this little presentation says, then time travel is just hopping through dimensions to an alternate universe. and yes the paradoxes in this idea of time travel don't exist.

The energy to go visit gramps,
Is a quadrillions fold greater in amps,
Than getting to Mars, indeed to the stars,
So why waste it in going all backwards?

If energy you have to sqander,
In trying all-time to wander,
Then go to the future, indeed to the next,
To create it in ways,
Devoid of our craze,
And sure to avoid our malaise.
