In 1929, Edwin Hubble found that the distant galaxies in the universe are moving away from the earth. He found that the speed of moving of moving galaxies depends on their distance from the earth. If a galaxy is ten times as far away as another, it is moving ten times faster than the other. This is what is called Hubble’s in other words, more distant galaxies are moving away from the earth than the ones closer to it. If a galaxy, 1000 light years. Away from the earth, are moving at about 177 km pr sec, moves twice that speed, i.e., 354 km per sec and soon.
