The universe is expanding and will keep expanding forever.
It was measured that the electromagnetic spectrums of stars in all the observed gallaxies(except for close ones) are shifted (red shift as a consequence of doppler effect), indicating that those gallaxies are moving away from us. this fits Enistein's general theory of relativity, specially when the shift was so high indicating that the gallaxies are moving at speeds greater than the speed of light which meant (with other evidences of course) that there's a production of space-time in the universe. so the universe is expanding by producing more space.
the universe is expanding and expanding at an accelerated rate as opposed to what was previously thought, as shown by the (doppler) red shift in stellar light
