It would occur to me that the entire concept of time travel is missing a major part of the equation. I am going over this and overe this in my head, and there is something missing, although i cant put my finger on it. if anyone has any ideas, however ludicris i may sound, please help. time, in my opinion , should be extremely easy to manipulate. It doesnt make sense that time should have "special" rules that apply only to it. the basic(extremely) principal that i am working with is that energy is modified through the use of resistance, and amplification. Mass, basically the same.. depending on the mass of any given object, this will define the ability to modify it. I.E, I can fold my jeans, but not a rock.we can modify time, in sound, by slowing a sound down, and just recently beginning to modify it with any reasonable quality, through the interjection of small sections of the sound, duplicated, and strewn throughout the original sound, and in energy, i am not so sure if this is a possibility, and this all may sound very elementary to all of you, and rediculous to others, but shouldnt we be able to modiufy time as well? i am under the distinct impression that we are making it much more difficult than we should. this is why i feel there is a massive (simple) solution that we are just not seeing. why should it be so very easy to block light by closing the shades, and covering our eyes... of course it is still there, but it isnt reaching us. there has to be some simple solution for blocking time, if it is to be percieved that time is relative to mass, energy, light, sound, and etc. everything can be modified and manipulated, you just have to use the right tool.
