...time variations caused by the distance vast distance differences between everything...do we extrapolate? Do computers have that capability...to map a billion different objects that all have millions of different time sequences that would seem to me to have to each be individually calculated...?

Which "true" are you looking for?

Currently we map the universe as we see it so e don't account for time. That means if you tried to fly to the Andromeda Galaxy using a current space map you would miss it by about 300 Light Years.

No one has tried to construct a map of the universe as seen by an outside observer. That seems to be the "true" map that you are looking for.

With the known distance to the stellar objects, the known speed that the travel and the known speed of light we can use computers to make a simple map of the Universe as it would be seen by an outside observer. It hasn't been done because we aren't flying around like Star Trek. If we did, then we would need those maps. Currently, the only star maps we need are those that tell us where to look for them in the night sky.

You are correct each stellar object's individual position would have to be calculated, but a ring of desk top computers could do it pretty easily. There are only 3 vectors to adjust the position on and the map would only have points; since space is so vast that objects would only be points. Our independent observer map wouldn't have to worry about the size of objects; we would plot the position of all the objects in a galaxy which would give us the stellar cluster or galaxy. The only problem is that there are a lot of objects out there so it would take time to calculate them. That's why I proposed using a ring of networked desktops; which could crunch numbers like a super computer. Divide the night sky among the computers and let one computer handle and plot the results. The calculations would be fast, very accurate and easy to plot.

Raymond, you're incorrect. The universe replaced into certainly a tiny factor, smaller than an electron, on the 2nd of the huge Bang. What occurred, we've faith, is that Inflation brought about this tiny factor to develop exponentially for a cut up 2nd. This explains why the universe is the scale it is at present. For the questioner, you would be surprised in case you knew how massive astrophysicists have faith the universe to be. in accordance to INflation concept, it is in all probability many, many time greater than the area that we are able to work out. 10 billion gentle years isn't something in this scale. the undemanding answer is that area CAN develop quicker than gentle. there is not something in relativity that prohibits. I see this query on right here many times. whilst astronomers say that something is 10 billion gentle years away, that parent does not think in regards to the develop of the universe. it is often calculated to boot, and it is primary because of the fact the "co-shifting distance". What this implies is that the galaxy cluster replaced into 10 billion gentle years faraway from us 10 billion years in the past, yet on the grounds that then the develop of the universe has carried us lots extra aside.

We can only map the observable universe as we find it right now, realizing that nothing we chart out there is still where we're seeing it. But then that's true of anything, no matter how far away or close it is. The speed of light sets the speed limit for the universe, and light takes time to get from point 'A' to point 'B.' Even just watching a car go by on the street you're never seeing where it is right *now* but where it was the tiniest fraction of a second ago.

just give it a rest stephen hawkins.....look at enya on you tube....type in 'only time 'and CHILL !!!! AND IF YOU ARE INTO PLANETS THERE'S OME WITH ALL THE GALAXY IN THE ENYA STUFF TOO. oops caps sorry !!!
