How does natural surroundings affect cosmology?

Answer 1

Everything we know about the universe is based on our ability to observe and measure varying degrees of luminosity/radiation within this fourth dimensional confinement; i.e., this is our known universe. Our known universe has many imposed limitations, based on our ability to observe and measure it, but no one can really estimate as to the actual age and size of the universe beyond the interpretation of empirical evidence we are able to gather and collate. As of matter of contention is whether these measures for age and size have any real meaning outside our observable universe. This is partly because the dimensional boundaries of our SpaceTime are always evolving and ever-expanding, per our ability to observe and measure it. Another aspect of for consideration is whether this small pocket of our observable universe is representative of the universe as a whole.
