Abstract
The path of a light’s signal is one and the same in the universal space regardless of the inertial frame by which it is identified. However, only one frame can be taken stationary and identified with the universal space while all other frames are moving. The direction of the path of a light’s pulse in a moving frame is determined in terms of its direction in the stationary one; the result is utilized to explain stellar aberration and show that the tilted direction in the moving frame depends only on its velocity. The aberration increment vector is introduced and employed to determine the apparent position of a star at each point of the earth orbit. Aberration in an earth satellite relative to the geocentric frame is presented. The direction’s change of a light beam between graded inertial frames promotes explaining aberration in an earth’s satellite in parallel to stellar aberration on earth.
Highlights
In earlier works [1] [2] the fundamentals of the theory of universal space and time (UST) were presented
The geometric distance R = OB between two points B and O in S is measurable by the time duration T = R c of a light trip B ∈ S → O ∈ S, which is the same as the duration of the light trip O ∈ S → B ∈ S
We found in [1] that a pulse of light emanating from (b ∈ s at B ∈ S ) and received by the conjugate observers (O ∈ S and o ∈ s) follows the same path in the universal space whether identified by S or s
Summary
In earlier works [1] [2] the fundamentals of the theory of universal space and time (UST) were presented. According to the UST, time intervals in an inertial frame S are essentially measured by corresponding spatial intervals travelled by light signals. How to cite this paper: Viazminsky, C.P. and Vizminiska, P.K. The light path is seen in the moving frame tilted from its direction in the stationary frame by the aberration angle. In the heliocentric frame the direction of the earth’s velocity, due to its orbital motion, keeps changing, resulting in every received starlight continuously changing its direction in the geocentric frame. The latter fact is manifested in a periodic change in the apparent position of distant stars throughout the year. Bradley’s explanation of stellar aberration proved inadequate since it couldn’t account for the negative results of Airy Experiment [4]
