"Right Hand of God" is, at least from a materialistic perspective, imagery and metaphor. It means that the human Jesus of Nazareth is at the central authority of the Universe because he is the One through whom the grace and authority of God flow.
If you are well-versed in the Bible and Historical Theology, then you will understand that Jesus of Nazareth is, by Christian thought, a man who came into existence at a particular point and time. But he is a man in whom "the fullness of THE DEITY dwells in bodily form (Colossians 2:8-9)." In other words, God miraculously conceived a man in whom God's own fullness, or "Logos" (mind, reason, word- see John 1:1) would dwell so that we could understand God, who in his essence is an infinite spirit that we could never know by purely human observation or reason.
So, God shows himself to us in human form, in a way we can comprehend. (see John 1:14-18, John 14:1-9). If you want to understand what God is like, look at Jesus. The simplicity of what Jesus shows us about God far transcends any theological or philosophical attempt to explain Him. When you see and understand Jesus, you see and understand God with all of the power and simplicity and unfettered genius of a child. Consider this exchange between Jesus and Philip, one of his disciples:
<< Philip said, "Show us the Father, and it will be enough for us."
Jesus answered, "Don't you know me Philip, even after I have been among you for such a long time? Anyone who has seen me has seen the Father. How can you say, 'Show us the Father'?" >>
From a materialistic space-time perspective, Jesus is currently non-local.
