    恰恰相反吧。。。一般认为去未来是可行的,回过去不可行

    永远不可能。

    To be honest, as for going across the time, I think it's quite possible, "theoretically", though not easy, practically.

    To try to grasp this concept, we have to come back to the basic concept of TIME.

    TIME might be intuitive, but actually it's something not so easy to imagine.

    To put it simply, TIME is nothing but a special kind of transformation(or change) in SPACE. If there is no change in SPACE, then there is no existence of TIME.

    First imagine a static "WORLD" with static SPACE with no TIME. However if some observer goes through the static SPACE in this static world, then TIME begins to generate for that observer.

    Now, what if the observer sets off from POINT A, goes around and then returns back to the original place POINT A? The world outside is completely the same for this observer and the observer could not tell any difference at POINT A. So we can say that the TIME is static at POINT A, or we can say that the observer comes back in TIME at POINT A. If the observer repeats the same path again and again, then the observer comes back to past again and again.

    The PATH that the observer chooses in the SPACE could be used to define the arrow of TIME.

    If the observer chooses different PATHS, then the observer has different kind of TIME with different arrows of TIME.

    If all the other the paths are invisible or forbidden to the observer, then the observer has no choice but only to go across the SPACE in a fixed path. The observer can never comes back to the past if this only available path dosn't return to the original POINT A, in such a static WORLD.

    In a dynamic world, things become complicated, so I'd like to skip that part. Just leave a hint here, in a straight dynamic WORLD, all points choose the same path in their own static WORLD, so that all points have same kind of TIME.

    If someone wants to go forth or go back in the WORLD, it means all the points in the world go forth or go back with the observer. This only happens in a quantum-similar World.

    Or, the observer breaks off all the barriers, get rid of the constrains on its time arrow and falls into another WORLD ahead or behind.

    And I suppose that, when an observer falls into some special kind of black-hole, the observer may have chances to see something happened in the past.

    呵呵,给你打个比方,你可以把宇宙设想成一个苹果,你要从空间中A点运动到B点,传统的方式是沿着苹果表面运动,空间穿越就好像一只虫从苹果内部打通了一条最近的通道。这个就是虫洞概念的来源,至于时间穿越就要复杂多了。

    时空穿越有波的穿越和粒子穿越两种形式态,波的穿越人类已经掌握,像声音,图像等均可借助起点发设器和终点按收设备做到跨越时间和空间层次的问题,量子技术只是波的极限形式,即直线波,有快速专一的特点。粒子的时空穿越在今后相当时期也不大可能,因为人类利用的最高能量也才到核能,核能这一级,对粒子属性的改变无能为力。

    在更高维的空间内你可以自由的拨弄空间那不就是过去未来你都可以去吗?

    你在光速或亚光速中相对你自己的时间接近0,你飞行到达10光年外的位置然后以同样的速度返航即可到达未来,对于你自己来说只是一瞬,但地球年以是你认为的未来

    穿越到过去不可以——宇宙自治
    可以穿越到未来
