How do we know about the CMB?
How do we "visualize" the CMB?

We use machines to translate what we cannot perceive with our bodily senses, but which is there, and make it perceptible to our bodily senses.

Maybe you're right, maybe I am not educated enough and I lack the necessary information, although I don't believe it at this precise point, because I think I know perfectly what objectivity and subjectivity are, maybe I'm wrong, but since I have used one of the definitions of objectivity and objective that appears in google when searching for it, namely, that objectivity is the quality of being objective and that objective is what is not dependent on the mind for existence; actual, and I have defined subjectivity equally as the quality of existing in someone's mind rather than the external world, and as in turn, you have rejected all these definitions, based on your higher education, it is necessary that you, and only you, teach me at once what these two words mean. Don't tell me that I should look it up on Google because you have not accepted those definitions, maybe after you refer to what you mean by these words we will find out that we have been having two different conversations and not one.

Mathematics, which serves as an example, but not as a definition, for what you mean, may serve to further prove my point, because mathematics is no more real than good and evil, in both cases we are talking about abstract concepts that don't exist physically and of which only the human perceives, indeed, can you prove that mathematics is more real than good?
