    A wormhole is a hypothetical time/space bridge between to points in real space vast distances apart. Also known as Einstein-Rosen Bridges. Basically it is a tunnel that shortens the time nescessary to travel Light years to days or even hours. It is a popular tool in science fiction to get around FTL problems and to explain away the Theory of Relativity. I myself have often wondered if it would be possible to create a stable Einstein-Rosen Bridge but to do so you would need exotic matter.

    I'm a skeptic on this point, if a wormhole crosses time, there would be a time paradox, as arriving before leaving. This would mean there is infinite matter in 1 energy, and infinite energy in 1 matter. This may be true, but i don't believe it.
    Growing up, i marveled at star-trek's science, and ignored the perfect society. Now, i try to ignore their science, and marvel at the society.

    Imagine, being able to create matter out of thin air, and not coming up with using drones for boarding hostile ships. Or using drones to defend your own ship. Heck, using drones to block energy attacks, counterattack or for surveillance. Unless, of course, they are nano-machines in your blood, which is a billion times more complex..

    No. They are purely hypothetical. It is not clear that they can exist.

    "Arriving before leaving" this means that we r going into the past . but i think practically we cannot go into the past , instead we can use these wormholes to get into the future .

    my opinion is moving into the future is easier than going back to past .

    "what is a wormhole?" = google is your friend!

    Why does so many reward lazyness?

    Yes, i'm moving into the future as we speak, 1 second at a time.

    Wormhole - Wikipedia, the free encyclopedia This, while being a wikipedia entry, has a lot of good information. Take a look.

    Yes, there would indeed be. However, the mere existence of a wormhole would not necessarily imply that it is actually traversable. Each end could, for example, be hidden behind event horizons, in which case it would be impossible to traverse it and emerge out the other side back into our universe. Likewise, it is possible that wormholes are not stable, and trying to traverse them would lead to their immediate collapse.
    All I am trying to say is that there are ways to effectively avoid any paradoxes, even though wormholes could exist ( for which there is currently no observational evidence ).

    Well, since they don't exist (that we know of) it's rather a moot point.

    They may exist (but still be unstable) in a Kerr black hole

    So, what about transmitting signals. That would be impossible as wel, as that would create another paradox. Then if we can not get signals from the other side, and we can't get there, how can we know it's a wormhole that crosses time?

    Hey, that's a good question !
    I would say that wormholes, while theoretical possible, just aren't very practical things...
