Uncountably many.How many disjoint intervals?  Only countably many.How many nested?  Only countably many.Intervals are disjoint, nested, or intersecting.Then there are uncountably many intersecting intervals, but theirintersections nest in them and their disjoints are disjoint.  For eachintersection there's a nest, and a disjoint.So, in ZFC, how many intervals in the reals are there?  Any two pointsdefine an interval, and in ZFC, there are uncountably many of those.Disjoint or nested Intervals in the reals inject into the rationals.Regards,Ross Finlayson
