Description
Is the sun further from the earth than it used to be? Are atoms or molecules further apart? Or are the galaxies further apart? Exactly where is this expansion happening? How much further away will the nearest galaxy be in say, 100 years?
If cosmologists admit we are in the dark about dark energy and matter, why are they seemingly so confident about other conclusions?
Where does the matter going into singularities go?
Since the light seen from the edge of the universe is billions of years old, those places must be
different than when that light originated, no? Why should we conclude that pulsars, for example, still exist?
The light we used to determine that the expansion is accelerating is billions of years old, so how do we know that this situation still exists? What about all the data based on energy that left its source billions of years ago?
The expansion of the universe is accelerating, but why the conclusion that it must continue to do so?
Could this expansion not be some lack of perspective on our part?
