Dynamic between two galaxies with an observer standing still in one of them
Between two galaxies, being one of them galaxy L (Milky way – Earth) and another one galaxy P (MUNICS S2F1-0323) of Z= 0.96000
An observer on galaxy P.
(ANIMATION)
Such observer thinks he is standing still.
In the age T1 of the universe, the galaxy P emitted a light ray at velocity c in direction of Earth, which used to occupy the position L1, distant x1 and moved away at velocity Vap.
In a time:
- the Earth covers the distance x2 ,going from position L1 toward L at Vap.
- A light ray at velocity c covers the distance X from P toward L, arriving at Earth in the actual age of Universe T = 13,7 billion years.
We have: T = T1 + T2
x = x1 + x2
An observer on the Earth
(ANIMATION!)
Such observer thinks he is standing still.
In the age T1 of the universe, the galaxy P that was on position P1, distant x1 from Earth, moved away at velocity Vap and emitted a light ray in direction of Earth, at velocity c.
In a time T2:
- the galaxy P goes from position P1, toward its actual position P at velocity Vap , covering the distance x2.
- the light ray covers the distance x1 at velocity c1 = c - Vap, reaching us nowadays.
We have: T = T1 + T2
x = x1 + x2
We must remember that “Logical Deductions” studies the motions of light in two different ways, as following:
- in the motion of galaxies in the absolute referential of Big Bang, which is the only one stand still. Such idea about absolute space is compatible with Newtonian physics.
- in other moving referential. Such referential are explained by Logical Relativity.
