so is it possible to tell where the 'big bang' started?

One shift two shift red shift blue shift

We have observed a blue shiffted light spectrum as in the case of binary stars As it orbits, it becomes more red shifted if at that point in its orbit its distance from us is greater and becomes blue shifted if its distance between us at that point is decreasing.

If the universe can be thought of as an explosion, then as everything began from the same point, ojects futhest from us must be moving faster away from us, [displaying greater red shift.]

The Red Shift theory is applied only between galaxies and not within the galaxy. if we are within the galaxy, there is no shift at all because we are all spinning at the same speed. Duuuhhhh.

It's not the first time science took a wrong turn. Edwin Hubbell was a genius, but like astronomers Galileo and Copernicus, "red-shift" theory is just wrong. Explain why no one ever observed a "blue-shifted" stellar light spectrum? In other words, why haven't any astronomers ever observed a star (sun) out there moving toward us? The more we learn, the more we realize we don't know... and the biggest obstacle to the progression of our understanding is our illusion of knowledge.

The center of the moving universe is where motion first started and if motion first started in the location of the Earth then we are at the Center of the Universe . Of the Millions of Galaxies with a Red Shift - about 100 hold a Blue Shift and they are in our local group - like Andromeda . At one time the universe was a motionless static gravity vauum field - if people here created a new particle that traveled back in space time then people started motion here on Earth and we are at the center.

@dizzo95 There is no centre of the universe, on a scale larger than superclusters of galaxies, everything in the universe is moving away from everything else. It would look the same from wherever you happened to be.

[dizzo95]

@finlarg The location where Motion first started in the universe would be where the center of the moving universe is . That does not explain where the center of the gravity vacuum field of the universe is. If both fields are falling ( or expanding ) there would have to be a point when there was no motion or matter. I have no idea where the center of a static motionless grum field would have been. Good thing helium 3 cannot freeze.

@dizzo95 "...there would have to be a point when there was no motion..."

If you're sitting on a chair, you're not in motion, relative to the earth. But you're moving at up to 1000MPH relative to the centre of the earth and 66,000MPH, relative to the sun. What I was getting at is that everything is in motion relative to something else. The concept of a still point in the universe is a non-sequiter. You also have to take the finite speed of light into account, so we look out AND back in time...

wow so i can have fun as soon as possible close my book and go out to see stars :D

O.....K....
