Try to name one that can't.

 Well, its infinitely long...
 ...(-1)------(0)--------(+1)...
  It has no end just like there is no end to the signed integers. Also, its infinitely dense due to the nature of the reals.
 ?

Yes.
Here's a mind bending fact concerning the reals and rational numbers.
Between any two real numbers there is a rational number and between any two rational number there is a real number. But there are only countably many rational numbers while there are uncountably many real numbers. :-)
Math lingo: "The rationals are dense in the reals". :-)
