Discussion Overview

The discussion centers around the apparent size of the Earth compared to the Moon as depicted in a photograph taken from the Moon. Participants explore the reasons for the visual discrepancy in size, considering factors such as distance and photographic techniques.

Discussion Character

  • Exploratory, Conceptual clarification, Debate/contested

Main Points Raised

  • One participant questions why the Earth appears smaller than the Moon in a photograph despite the Earth being larger, referencing a specific image.
  • Another participant suggests that the initial claim may have been intended as a joke, indicating uncertainty about the seriousness of the discussion.
  • A third participant confirms that the joke was made but reiterates the question about the size discrepancy in the photograph.
  • Another participant argues that the size appearance can be influenced by the lens used in the photograph, explaining that different focal lengths can alter the perceived size of objects.
  • A final participant expresses interest in the topic but does not pose further questions.

Areas of Agreement / Disagreement

Participants do not reach a consensus on the seriousness of the initial claim, and there are competing views regarding the interpretation of the photograph and the factors affecting the perceived sizes of the Earth and Moon.

Contextual Notes

The discussion involves assumptions about photographic techniques and the interpretation of visual information, which may not be fully explored or agreed upon by participants.

In the picture of the Earth from the moon I have here:

If the Earth is the same distance away from the moon as the moon is from Earth (making it clear) and the Earth is so much bigger why is the Earth so small in the picture while the moon is so big in the sky. Yes, the Earth is is blown in two and the other half got suck into a black hole. But, you can still see how big the Earth is since the Earth is round.

Am I correct that this is a joke? (Yes, I must be very dense to have to ask this question. It actually wasn't until I read the "Yes, the Earth is is blown in two and the other half got suck into a black hole." part that I tumbled to it!)
 
Yes the last part was a joke but the picture is real, why's the Earth smaller than the moon.

If you're serious...

You can't go by a photograph. If a photograph was taken using a lens with a comparatively small focal length, then the Earth will appear small. If you use a lens with a larger focal length, the Earth will appear bigger. Think of a zoom lens.
