There are tiny holes that go all the way through airplane windows called "breather holes," and they regulate the amount of pressure that passes between the inner and outer panes of glass. The breather hole ensures that in an emergency situation, the outside window pane breaks instead of the inside window, which makes it so the cabin pressure isn't affected. In addition to ensuring the maintenance of proper cabin pressure, these holes also help to prevent fox between the panes of glass.
This is not up for debate and is a scientific fact. This hole is not large enough to effect cabin pressure and is very important for maintaining the stability and integrity of the plane. It is barely detectable to the naked eye and does not cause any problems or noticeable changes.
These holes , while they do exist, only exist in the first layer of the window. You can see this should you ever board a plane. They are in the inner window pane, and they function to stabilise cabin pressure and to act as a second layer of protection should the outer window become damaged.
The tiny holes at the bottom of airplane windows keep moisture from building up between the panes. It also has something to do with keeping the inner pane from breaking from the outside air pressure. I've never actually seen the holes myself, but I've certainly read about them so I know they exist.
No, airplane windows do not have tiny holes that go all the way through. Airplane cabins are sealed and pressurized. Holes would not work in this scenario. The small dots seen on windows are not holes. They may be small spacers located between airplane double windows, but they are not holes.
