Asked in Aristotle
How did Aristotle's inability to detect parallax lead him to propose a geocentric model of the solar system?
He reasoned that since parallax could not be observed for celestial objects near the sun, then the earth was stationary. This erroneous assumption was because at the time he had no way of knowing that celestial objects were so far away that their parallax angles were too small to detect.

Asked in Astronomy
Can you practically see an object the whole 13.7 billion light years away?
Not with your eyes, you can't. The light from far-away objects is so spread out that the amount entering your eye is not enough to be recognizable ... it's too dim. But that's exactly what telescopes are for ... not to 'magnify' objects, but to collect a lot of their spread-out light, and make them appear brighter. The combination of the biggest telescopes we have, plus the most sensitive detectors we have, plus the longest possible exposures, have so far been combined to detect objects that are believed to be between 13.5 to 14 billion light years away.
