Here is what you said earlier
"if I don't experience something with my senses, it doesn't exist FOR ME and has no meaning. It may exist for others, but it doesn't for me. Clear enough?"
And you also said
"SA, you "think" the pen is not moving. But actually it is. Because it is on Earth which is moving in the Solar System which is moving in the Galaxy which is moving, and so on"
If you are sitting in your office do you sense the earth is moving?
you also said:
"But I meant that things we cannot observe have no meaning for me (no matter if they exist or not). The point is not if they exist, the point is, can I experience them. If 'yes', they mean something to me, if 'no', they mean nothing to me."

So basically any science field which you do not experience have no meaning to you, I am sorry to tell that this put you in grade of people who do not appreciate knowledge and science because you stated by your self that any thing you do not experience has no meaning to you.
