that's what I was thinking log or exponential growth along the axis using a non-linear graph. I have found some interesting sites that use this approach to demonstrate relativity. As you have mentioned everything is in motion so the graph will end up being a dynamic animation. I also am very...
Thanks all for the data. So here is the project for this year ( child is in grade 9 but has been into astrophysics and relativity for years now). We will draw a line apprearing straight to the artist on various planets in our solar system. The imaginary viewer (our output) will be just outside...
please feel free to leave more comments while I play with the scales and I will take all information into account so that I can post a link to an example to what I am attempting to produce as soon as I have a working model. This will probably clear up what I am poorly attempting to explain as I...
ok assuming sol and it's system of planets is in a circular orbit around the center of the galaxy, which is about 26k ly thus it is a constant. if we are graphing that point (the center) from Earth then the orbit of Earth around the sun is a variable and the rotation of the point on Earth we are...
I think for the for this project we should begin where we would see it now ( ? years ago ) and proceed to our relative time which would put it in the future. The difference in time of our orbit around the sun would be negligible compared to the time to the center of the galaxy, correct...
Just ran into the European Space Agency's Gaia telescope which launched in Dec. 2013 and it appears they are collecting just the data I/they require to produce a 3D map of the Milky Way. This should keep my son busy with real numbers for the next few years. It is most cool when science and...
I have begun the basic geometry for the formula.
1. using the center of the galaxy as the point to be graphed from our perspective.
2. our solar system's orbital period is 225M -250 Myr and it has a rotational axis is ? (read a part of a post in general astronomy but in was not much help)...
Any thoughts on using a single point instead of a line? The point representing the center of the galaxy the using the 3d model(s) to graph a 3d graph of our position relative to this point.
Well I found a start, NASA had a vrml model of the milky way. I am in the process of importing this into Autodesk 3ds Max. I will see what "scale" they have used to produce this model. It uses a 44,000 star representation of the galaxy.
Data from NASA...
now you have the correct question. the result would be a squiggly line representing a straight reference line as viewed from an orbiting planet in an orbiting solar system in an orbiting galaxy. but without the 3d this line would need to be drawn as time dependent animation showing the cursor...
The line would reference the newly discovered gamma-ray bubbles as the north/south poles of our galaxy. Now if I could plot the orbit of our solar system using a simplified representation of the galaxy we could calculate the Earth's rotation within it. Then we could display the resulting line as...
Thanks for the reply. The idea came as a discussion of what a absolute reference line would look like from our perspective on Earth. Yes the universe idea is off the table. But a model of the galaxy with a line passing thru it's center at a right angle to it's rotation and a model of our solar...
I am looking for information to assist me in designing a model or program to draw a straight line bisecting the universe. Ok maybe just the Milky Way galaxy. I would like to view this line from various points 1. as viewed from a point on Earth (possibly one of the poles) 2. as viewed from a...
