Hello Everyone

This is my first post and question.

Since the speed of gravity and the speed of light are the same, the universe 13.7 billion years old and according to the link below the universe 156 billion light years across

Does that mean that we are only affected by the gravity of the universe that is see within 13.7 billion light years?
