Let's take his example -
If Person A and Person B are situated at the same point in space and look at Andromeda at the same moment - why would Person B's momentum cause him to see events on Andromeda days apart? How does the light from Andromeda reach Person B's eyes sooner than Person A's eyes if they are at the exact same point in space when they look up?
IF the momentum/speed of the observer affects how Andromeda would be perceived, how would the pathetic speed of a human running at a generous 28mph result in a matter of days apart from a stationary observer? To give some sense of scale, 28mph is 12.5m/s. The speed of light reflecting off of Andromeda is an eye-watering 299,792,458 m/s.
We could test his fantasy using the scientific method. All one has to do is compare the photographs of a stationary telescope to a telescope moving at 28mph to see if the activity recorded on Andromeda appears days apart. I am not a betting man, but my bet would be they would be identical. No doubt, he will never do this, nor will the listeners.
Of course credible scientists will have no need to test his theory since it is clear that he is wildly confused about the Andromeda Paradox, which was first put forth by Roger Penrose. One such scientist reveals as much in this
YouTube Video.
Changing gears,
In regards to the original video: Have you ever heard of the word factoid? Factoid - "an assumption or speculation that is reported and repeated so often that it becomes accepted as fact." Most of these crazy viral videos about time come from scientists influencers who are basing their concepts on the Theory of Relativity - which in physics and academia has become more of an orthodoxy than anything rooted in facts. It has lead to all sorts of bizarre fantasies regarding time-travel that appeals to identities who psychologically and psychicly feel themselves to exist over time.
Yet the only moment of time that can ever be experienced is now. Time is eternally now.
All perceivers are experiencing the same moment of time regardless of their perception.
