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

[john1800]

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.?

lets say the big bang starting point.?

There is no such thing. The closest you can get to a concept such as this is to find the relative speed between the Earth and the CMB rest frame. This speed is around 300 km/s.

so we don't now the Earth speed,or direction in space.the true speed at least.my question is.if we don't now the speed or direction of Earth we are.but we measure something with a speed in relation of CBM frame.that we can't 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.?!

 

[Orodruin]

the true speed at least

It is not a question of not knowing something like the true speed, it is a question of the concept not existing.

if we don't now the speed or direction of Earth we are.but we measure something with a speed in relation of CBM frame.that we can't 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.?!

From this it is completely unclear to me what your question is.

 

[john1800]

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?

 

[Orodruin]

if the speed of light in relation of the space is 0

What does this mean? The speed of light is not zero. This makes your post read like word salad.

 

[john1800]

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

 

[Drakkith]

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

The speed of light is c, approximately 300,000 km/s, in all non-accelerating reference frames. Note that there is no such thing as a 'cosmos frame'. You cannot assign a frame of reference to space itself or the entire universe.

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 can't to go faster.you always can go faster.you can not be slower than zero.thats probable.

Unlikely.
