Regarding the movement of celestial bodies and the perception of time, it's important to note that our understanding of the universe is based on scientific observations and theories. Gravity plays a significant role in the movement of objects on a cosmic scale, and its effects can influence the perception of time in certain circumstances.
According to Einstein's theory of general relativity, gravity can bend and distort spacetime, causing the flow of time to be affected. This phenomenon, known as time dilation, means that time can move differently in regions with different gravitational fields. For example, in the vicinity of a massive object like a black hole, where gravity is extremely intense, time would appear to move slower for an observer compared to someone in a weaker gravitational field.
However, it's important to clarify that time dilation due to gravity is not something that can be directly felt or experienced by individuals. It is a concept that emerges from the mathematical equations of general relativity and has been experimentally confirmed in various scenarios.
As for aliens in human form or their influence on gravity and the perception of time, that falls within the realm of science fiction and speculation. While it's interesting to imagine such scenarios, there is currently no scientific evidence to support the existence of extraterrestrial beings or their abilities to manipulate gravity or time.
