Question: With the assumption that hubble parameter 'H_0' from v=(H_0)*r is constant, I would like to ask you a question. Will there be more and more objects that will not be visible as time goes by? I ask this because, if some object is initially some 'x' light years away, say, "3billion", after certain amount of time, because it is moving away from us with velocity v=(H_0)*(x), it will be farther away from us. Then, if H_0 is held constant, it will now be moving away from us at a greater velocity. v=(H_0)*(x+Δx)... If this goes on until v becomes greater than 'c', the speed of light, the light that object will no longer be visible. Therefore the object will be no longer visible. Is my reasoning correct? If it is, does that mean the number of objects visible for us is decreasing in numbers? Thank you for your help.
