Stargazing

FULL COLOR. 32 pages. Extract on Starlight Aberration from book Relatively Simple, 2nd Edition. This extract from Relatively Simple gives a taste of the book's scope. The chapter on Starlight Aberration shows that - in stipulated circumstances, in this case in relation to Earth's velocity in orbit around the Sun - the aberration is from a relative light velocity with respect to a stationary observer on Earth. A chapter on Light-beam Alignment shows that electromagnetic radiation (em) passes direct from a fixed source to a target (observer) also fixed in the same reference frame - for example, both fixed to Earth - irrespective of their, combined, movement as part of the movement of that reference frame.
