Amazing Planetary Movements

[Witness1970]

A simple image of the way the moon moves if we look at the solar system from directly above.  As the moon orbits the Earth and the Earth orbits the sun, the moon's movements become more complicated.  The moon takes about 27.3 days to orbit the earth, and the moon phases repeat about every 29.5 days.  The difference is due to the fact that as the moon orbits the earth, the earth is also moving around the sun.  It is the relative positions of the sun, earth, and moon that creates the phases of the moon that we observe.

 

If we add in the movement of the sun around the center of the galaxy, it creates a completely new picture.  Once again, we are taking a certain perspective.  This image is a view from directly above the galactic center.  The orbit of the sun around the center of the galaxy is estimated to take somewhere between 225,000,000 and 250,000,000 years.  The image below is an approximation of what you would see from directly above the galactic center.

This is showing the movements of the moon around the earth, which is moving around the sun, which is moving around the galactic center.   None of these orbits are actually perfect circles but are actually more elliptical.  This, of course, is a simplified image.  The image shows the movements of the moon but only uses 16 circles.  An image showing between 225,000,000 and 250,000,000 would of course be ridiculously large.

 

Even more complicated would be trying to show the movement of the galaxy through space.  It would be a very complex image.  And these images are just from one viewpoint, above (or below) the galaxy, perpendicular to the plane of the galaxy.

From another viewpoint, we get a different perspective from the one above.

Is this model perfect?  NO!  In the video, he states that the heliocentric model of the solar system is wrong.  It isn't wrong, it is merely from a different perspective, a different viewpoint.  The heliocentric model of the universe works just fine from one perspective and the model shown above is fine from another perspective, and this video just shows the movement from a third perspective. 

 

The video is very nice but has its own flaws.  As the sun moves around the center of the galaxy, there is something of a wobble so that the sun is sometimes slightly above the galactic plane and is sometimes slightly below the galactic plane.  The video does show how the sun moves through space as it orbits the galactic center.

Is time real?  This might sound like it is off topic, but is it really?

 

There have been science fiction programs about travelling through time.  But what is time really?

 

We measure time with movements of the heavenly bodies.  When the earth makes one rotation, it is called a day.  It actually takes 23 hours and 56 minutes for the earth to rotate one time, but since the earth is also moving around the sun, it affects what we observe to be a day.  When the earth makes a complete orbit around the sun, it is called a year.  It takes 365.2422 days for the earth to make one full orbit.  This means we need to use 97 leap years out of every 400 years to keep the seasons close to the same time of year.

 

Since our measurement of time is based on the movements of physical objects, time is really just another space dimension.  So, this post is still about planetary movements, since time is just a measure of the relative positions of objects as they move.

 

When we make appointments, it is said to use 4 dimensions.  A street address (which can be located using latitude and longitude) on the 4th floor meeting room, a measure of height (a 3rd dimension) and the time is 9:00 AM (a 4th dimension).  But when we say 9:00 AM, we are really describing time in terms of the position of the sun relative to our position.  This means that the time mentioned is just another description of the position of heavenly bodies relative to our position.  

 

No! We can never travel back through time.  The past does not exist except as a memory.

Gravity travels at the speed of light.  If the black hole at the center of the galaxy suddenly disappeared objects would begin to drift away.  Anything within one (1) light-year would start to drift away after one year.  The solar system, which is approximately 25,000 light-years from galactic center would start to drift away after 25,000 years. The edge of the galaxy, which is approximately 50,000 light-years from galactic center would start to drift away after 50,000 years.

 

If you could observe this from a position 100,000 light-years from the center of the galaxy, everything would appear to start drifting away at exactly the same time.  The object that is 1 light-year from the center would start drifting away after one year but the light from that object would take another 99,999 years to reach us.  The solar system would start drifting away after 25,000 years and the light from the solar system would reach us after another 75,000 years. The objects at the edge of the galaxy would start drifting away after 50,000 and the light from those objects would take another 50,000 years to reach us.  Simply put we would see all these things 100,000 years after the black hole disappeared.  I am of course talking about the objects that are on the side of the galaxy nearest to us.  Other objects would take completely different calculations.

 

If the gravity from the center of the galaxy somehow diminished 30,000 years ago, our solar system would be reacting to the gravity that existed 25,000 years ago.  The edge of the galaxy would still be reacting to the gravity that existed 50,000 years ago since the gravity change has not reached out that far yet.

 

Mind-blowing thoughts!
