William Herschel Thought That the Sun and Earth Were Roughly

William Herschel thought that the Sun and Earth were roughly at the center of the great grouping of stars we call the Milky Way. Today we know this is not the case. What was a key reason that Herschel did not realize our true position in the Milky Way?

A) he did not have a telescope, and most stars are too far away to see without a telescope
B) his telescope was only able to show him objects inside the solar system, and not objects in the Galaxy
C) the dust that extends throughout the disk of the Galaxy only allowed Herschel to see the small part of the Milky Way that surrounds us
D) there are so many black holes in the Galaxy, that they absorb a substantial part of the light from distant objects; we needed x-ray astronomy to see to more distant regions
E) Herschel shared with ancient people the firm religious belief that we must be the center of everything
