THERE ARE NO ANSWERS or conclusions for everything but instead everything is a kind of continuum. Whether we look out into space or deep into consciousness we are sometimes tempted to make a theory of everything or find the answer for the beauty of the universe but we probably will not solve the mystery. We have unraveled some of the ingredients and laws of how they fit together but there is no one overarching truth. We can make inroads into the mystery of Gravity but it may be possible to get closer however some people will give up and just blame/praise God.
I can view our lifetime as brief as the appearance of virtual particles popping into existence within the fullness of cosmological time. I can almost conceive of infinity. It is up to your POV to view demonstrable but hidden fields in our universe. The LHC is looking for extra dimensions. Dimensions we do not see is not a strange idea.
The confluence of the obvious nature of time and then knowing what time actually is , is a mystery. We know what time does but not
what it is. Perhaps you thought we should know more than we do. Cosmology is the science of speculation. Even Astrophysics has to leap to assumptions.
