B What is the speed of the Earth traveling through the cosmos?

what is the speed of earth as it travels the cosmos,compared with the center of the universe.lets say the big bang starting point.?

 

so we don't now the earth speed,or direction in space.the true speed at least.my question is.if we dont now the speed or direction of earth we are.but we measure something with a speed in relation of CBM frame.that we cant go over it even in mathematics.and its always the same.can we imagine that this speed may be 0 in relation not the CBM but the space.?!

 

my question is.if the speed of light in relation of the space is 0,and we are traveling with the speed we mesure as its speed.will it solved all the problems we have with its speed? is this a possibility?

 

its not zero in relation of CBM frame.it may be zero in relation of cosmos frame.lets say.can it be?

 

i now,You cannot assign a frame of reference the entire universe,but maybe that is the problem,maybe that is why It doesn't vary whether the observer is moving or not.maybe that is why you cant to go faster.you always can go faster.you can not be slower than zero.thats probable.
