I would like to know some more information; where did it all start? What is the geographical 3d coordinate of the point of origin of everything that expanded from the big bang?
How do we know that the instruments we might use to try to measure relative distances and the atoms comprising them are not themselves expanding?
How do we know that all the atoms of all mass including the atoms we are made of are not themselves expanding, and this is not the real reason we stick to the planet?
