Perspectives in Space & Time

The Proper Motion of the Stars of Ursa Major

The stars of Ursa Major

The video below shows the movement of the stars of Ursa Major over thousands of years, revealing how the constellation changes over time as seen from our solar system. Ursa Major may look like the Great Bear now, or a Big Dipper, but this was not always the case. The star charts below the movie reveal how the constellation of Ursa Major looks from an entirely different star system, from a different location in space at the very same time as it looks from our view point—dramatizing how our perception of reality is relative to our punctual moment (this lifetime) in space and time. In the final video we leave our solar system in an interstellar space craft and travel around the star Dubhe of Ursa Major

Although the stars are often referred to as "fixed stars," this is a relative phrase meaning that the stars move negligibly from our perspective in space in a relatively small time span. Thus, the stars appear fixed in space compared to the planets rotating around our Sun, but this is true only during this limited time span. Stars do however move and they move in different directions and different speeds throughout our galaxy. For example, our Sun (and solar system) is estimated to be hurtling through space on its own sojourn at about 720,000 km/hr (that is almost 1/2 million miles in one hour). Stars sometimes move in groups, with those groups moving in unique directions, in a star-stream. A star's (souls's) movement is referred to as its "proper motion."—are you following yours?

The word "star" means avatar, a shining living being, a soul, like our Sun is the soul of our solar system. A stars apparent fixed placement is similar to what may seem as little soul growth occurring in a lifetime from the perspective of the lifetime. Yet, over soul's durative journey beyond a punctual moment, one incarnation, soul evolves beyond what is comprehensible from the perspective of soul's short visit on Earth, like a star traveling incredible distances with a unique speed and unique direction. Like stars, souls may travel alone on some unique path, or they may travel in groups, referred to as a soul family, with each soul participating in the family's soul-stream of evolutionary growth.

So what is truth? Is there a fixed absolute truth, or is truth always relative based on our current bubble of perception? We all have an individual perceptual awareness of our reality and we all have different thoughts to validate what we perceive. We also have perceptions and thoughts that are common to us all that we uphold through mass-consensus, but this is only due to our common location in space in some limited amount of time. To relinquish our constructs of thought that we use to define and defend our current perception as truth, whether individually or collectively, is to relinquish the bounds of space and confines of time. We then become aware that truth is limitless and that we are unbounded beings. In doing so, we set ourselves free to become whatever we choose to imagine.

Unlike the five middle stars of Ursa Major (Mizar, Alioth, Megrez, Phecda and Merak), which move as a loosely knit group in the same direction, Benetnash and Dubhe are not of this group and move in different directions,

Our Solar Neighborhood

Imagine taking a trip in an interstellar space craft. In the video below we leave our solar system and travel around the star Dubhe of Ursa Major while maintaining the same distance from Dubhe as we currently are (~124 light years), thus making a perfect circle around the star. When we get to the far side of Dubhe, we will see our own Sun, now a tiny star, pass behind Dubhe. The stars are not moving in this excursion, they appear to only because of our changing vantage point. This gives you a feeling for how the constellations, as we know them, quickly morph into other forms and dissolve all together when leaving our home star. It also makes apparent that you can no longer navigate the heavens simply by identifying stars in their familiar locations as we do here on Earth. Interstellar navigation requires an entirely different approach. One common proposal is to use the precise timing signals of x-ray pulsars to navigate space. Not running into a another star is yet another concern, especially if traveling at warp speeds, and stopping along the way to ask for directions may not be the best option.
