No, Open intervals are intervals that exclude the endpoint from the
interval, and thus don't HAVE an "endpoint".

Intervals consist of points. Where no point is, there is no interval.
Where an interval is, there is a point. The belief in an interval-end
without points is pure matheology.

But there isn't a spot on the line without a "point", so there is no
spot with "no point"

Therefore the end of an open interval consist of points.

The "end" of an interval is a number such that no element is larger/
smaller, defined as the limit, which may or may not be included.
