How was Hubble able to provide evidence that the universe was expanding?

He noticed that the light emitted from galaxies is 'red-shifted'. This means it is slightly redder than it should have been. This is due to the Doppler Effect. The Doppler Effect is when things are moving towards you the waves are closer together and when things are moving away from you the waves are further apart.

Who stated that the universe is still expanding?
Hubble did not conclude that the Universe is expanding. Hubble thought the red shift indicated a unrecognized principle of nature. Hubble's constant actually shows the universe is bounded at R=150kMpc/31 and H= c/R = 62km/s/Mpc. The increase red shift velocity indicates a decreasing universe.
Is the sun expanding or contracting?
We believe that the universe is expanding.The universe is currently expanding, as evidenced by the Hubble Constant, which indicates that the greater distance a star is from an observer, the faster that star is receding away from the observer. This Hubble Constant holds true for all observers, no matter where they might rest in the universe, and the Hubble Constant applies to all stars in all directions of the sky for each observer.
Was Edwin Hubble an astronaut?
No. But his name was used as a satelite! He was an astronomer thus the hubble telescope. I believe it was he who discovered the expanding universe.
Who was the astronomer that discovered the universe was expanding?
Edwin HubbleAnswer2:Hubble did not believe the universe is expanding. The universe is not expanding like the big bang, it is excited like an atom. The electrons jump to a higher level and lower their speed. The lower speed is a lower energy state, the max energy is when v=c.Hubble;s relationship v=HD indicates the distance D from the max energy state, where v = c.Hubble's Constant is dR/Rdt =c/R =H = 300M/150TT = 2E-18 m/s x31E21 = 62km/s/Megaparsec.
Who showed that other galaxies existed and observed that the universe was expanding?
Edwin hubble >:d
