Just a quibble. I don't know what the consensus is on the underlying
physics, but if the quote above is an accurate description "it looks as if
the universe will expand forever and the mass density will get lower and
lower", then the conclusion "eventually it will reach to nearly zero"
doesn't follow. Remember asymptotes. The density can keep getting lower
forever, without ever getting close to zero.
