    As far as my understanding exists, nothing can travel faster than the speed of light? And if we even can, it would make time stand still? or even retard that time backwards? (Like a car wheel spinning really fast). My actual question is... If we can travel faster than the speed of light how can we see where we are going? I have also thought that if light has been there before then there creates an area of illumination and hence, no place that light has not travelled.

    I am interested in any thoughts.

    (...)

    This is based on the idea that you do not know where you are going until you are given a reference. So, once again, I ask, how can future time exist?

    you will see it double or in multi-universes

    If you went faster than light, I suppose you would see every beam of light moving backwards toward you as you catch up with it. But also, your internal energy due to your mass would appear to be less than zero to any observer that perceived you to be going faster than light. I can only guess what the consequences of that would be. Distances would have to contract from your perspective to less than zero. So..... I don't know... would that mean the sequence of objects in front of you would be inverted, with the furthest object away now appearing to be the nearest?

    As you can see, the universe as you observe it would now be a bunch of gobblely gook, craziness. At minimum it would require the same kind of approach as imagining the area inside the event horizon of a black hole, reorganizing your coordinate system and such, or maybe it would even be worse than that?
    Some clocks are only right twice a day, but they are still right when they are right.

    To RJC, etc:
    I don't think we, as a material person, could possibly go faster than light - all the laws and theories of science go against it. But we are more than just a heap of atoms and molecules. So maybe a weightless bit of us can travel faster than light and go backwards in time.
    A number of proper scientific experiments, studying cosmic reactions in the upper atmosphere and monitoring the arrival-times of the cosmic particles and the normal particles; it was found that some "particles" did, actually arrive before the reaction took place, being so strange and being created by such an explosive reaction, there was enough energy for them to "break the light barrier".
    Ring any bells wrt the sound barrier?
    The main problem is that one can only observe back in time, to prevent one killing one's parents, or otherwise creating a contradiction.
    I'm also interested, but suspicious, about two more concepts in this arena:
    1. What our brains can do when we are "asleep".
    2. What parts of us are non-material, and what parts of us exist in other dimensions than our main ones of 3 dimensions and forward-moving time.

    When something is going back in time,one of his steady state is double place, so at least there is a statistical effect on the former.

    There appears to be little point trying to make sense of anything Water Nosfim writes. It appears to be a cryptically expressed mixture of misunderstood science and his own wacky ideas ...

    It's just one particular poster but the topic still pertains to physics.

    Another thing to note is that observers would disagree. From the perspective of others observing you from an inertial frame that perceived you to be going faster than light , time would appear to be going backwards on your space ship, and energy would be flowing into your ship instead of being radiated away from you. From your perspective, they would be the ones for whom time was flowing backwards. Length would be contracted to less than zero, which I'm assuming means it would get inverted. I guess you would note that whatever had been the last thing in front of you before you accelerated to that speed is now the first? Or maybe you would perceive yourself to have turned around and headed the opposite direction of where you set out to go?

    I think we can construct a logically consistent picture of how the situation would look. ..... which could mean it's actually a possible situation in some sense? Certainly you're not going to get to that point by just firing rocket thrusters for a long time, though.

    And I'm still going to stick with my original suggestion, that it's kind of like imagining what happens inside the event horizon of a black hole. We know the inside of the horizon exists, but that doesn't allow us to do much more than speculate about what's actually happening in there.
