The discovery that spectral red shift was proportional to distance. That proportionality constant has the dimension of time, and when evaluated comes out to 13.6 billion years. Which leads to the conclusion that there was a big bang that many years ago.

From the observed red-shifts, which were occurring in all directions, Hubble concluded that either (a) Earth was at the center of the Universe, or (b) The Universe was expanding in all directions at all points within it. Since (a) seemed rather facetious, he concluded it must be (b)

It realized that all the galaxies were moving away from each other, which could only mean an expanding universe, like blowing up a baloon and watching dots on it get further and further away.

Well, the first answer may be correct from certain points of view. But, in real life, our solar system is contracting as the sun slowly pull us in. Telling people this would cause wide spread panic (Just look at those freaking over Global Warming), even though, it be Thousands/Millions of years before the Earth go out in a "Blaze of Glory".

Indeed, Snagelfritz, from some points of view the universe was created by the Flying Spaghetti Monster.

like today u see this star as it is. the next day,u see the star a bit further from it's original coordinate.draw some dots on a balloon and blow it up.u'll see they move away from each other.
hubble saw the galaxies move away from one another

You can thick of the Doppler effect like the sound of a train coming towards with that higher pitch sound (the sound waves are being compressed) as it passes you the pitch changes again ( the sound waves are being stretched)...This happens to light, as the object moves away from you the light is stretched into the red waves of the light ..telling us its moving away from us.

The dopler effect or red shift
he saw the stars going into the red part of the spectrum.

Red shift of the observed spectrum of receding stars and galaxies.

He observed that the 'red shift' (Doppler shift) of galaxies became greater the further they were.
