Looking through a lens or a {{w|microscope}} in {{w|biology}} and other disciplines does magnify short distant objects. And a {{w|magnifying glass}} works more like a microscope when your eye lense is close to the {{w|focus}} of the magnifying glass, but when looking at distant objects you have to increase the distance between the glass and your eye where the {{w|focal length}} of your magnifying glass must be increased to meters instead of | + | For objects at a great distance one can achieve a better view by using a {{w|telescope}} as it is the typical method in {{w|Astronomy}}.

In the comic, the objects being viewed by Megan could be {{w|stars}}, {{w|galaxies}} and the {{w|planets}} of our {{w|Solar System}}. [[Megan]] is using a telescope. [[Beret Guy]] attempts to view them using a step-ladder to get closer to the stars, and then looking at them through his simple hand-held magnifying glass. This approach could be successful only if the stars were a few meters away, so that the ladder would take him within a few centimeters of the study object. In fact the visible stars are several {{w|light years}} away (typically 18-20 orders of magnitude further away) and getting two meters up on a ladder won't make any perceivable difference.{{Citation needed}} (Unless, of course, you are Beret Guy.) | In the comic, the objects being viewed by Megan could be {{w|stars}}, {{w|galaxies}} and the {{w|planets}} of our {{w|Solar System}}.
