But in the theory of relativity, it is your perspective on an object or an event that gives you an illusion. To paraphrase Einstein, one of the reasons is that the trajectories are relative. However, these are not familiar hallucinations, because they are exactly what we see from that angle-your brain has no influence.
The following examples include visual processing and perspective effect, but my goal is to organize perspective effect. Relativity is the comparison of the measurement results of an object or an event by two different observers. The variables that affect the observer's perspective are: distance, direction, movement and environment. Change any of these variables, and you change the observation or the result.
The perspective illusion of the solar system is one of the most persistent and underestimated optical illusions in human history, which has been puzzling rational human beings since the beginning of our existence. It is easy for us to be complacent and ignore this ignorance a long time ago, because we all know that the earth moves around the sun, just like all planets.
Although we have a lot of "knowledge", and we know that the sun does not go around the earth, nor does it rise and fall in the sky, we will always see the fact that:
Maybe you will be surprised to find that the sun moves like this. From our point of view, a year is like this:
We are sure that the planets in the solar system revolve around the sun in this way. This is correct, but only from this angle, but if we change the angle, it is actually a better description of the motion state of the solar system and its planets, only now through the Milky Way:
Once again, we know that the earth has been going around the sun, but we may be skeptical about this fact, just like the confusion of early humans about sunrise and sunset. If this is our view:
Once again, we know that the earth has been going around the sun, but we may be skeptical about this fact, just like the confusion of early humans about sunrise and sunset. If this is our view:
Please note that from this point of view, the moon revolves around the earth, but from the surface of the earth, if we don't know better, we may be confused, because this is what we will see, always:
An earthman who was born and raised on the moon will swear that the following photo represents how all this works, and may even think that the earth belongs to the moon, um ... the moon.
Interestingly, from the surface of the moon, the earth is lying on its side.
This provides a very interesting scene for us to observe the moon, especially when the same side of the moon always points in our direction.
