that the universe is expanding.
The evidence - for example, from the redshift, normally attributed to a Doppler effect - is that indeed, the Universe is expanding.
It means that the light from galaxies is losing energy. The only reasonable explanation for this is the cosmoligical redshift - that is, that the Universe is expanding.
The expansion of the Universe results in the light from faraway galaxies being redshifted. This is called the "cosmological redshift"; it can be compared with the Doppler effect (which also causes a redshift), but the details are somewhat difference.It is an observed fact that most galaxies are redshifted; the explanation that seems most reasonable is that it is caused by the cosmological redshift. This means that space itself is expanding.
Redshift does not expand the universe. Redshift is a physical quantity that is used to describe the expansion of the universe. The current time has a redshift of zero. at redshift 1, the universe was half the size it is now. At redshift 2, the universe was 1/3 the size it is now, and so on. if redshift is z, then (size of universe at redshift z)/(current size of universe)= 1/(z+1)
that the universe is expanding.
because the universe is expanding.
The evidence - for example, from the redshift, normally attributed to a Doppler effect - is that indeed, the Universe is expanding.
The red shifts show the galaxies are under centripetal force and the red shift indicates the centrifugal force. This indicates that the universe is in continuity, the centripetal and centrifugal forces are in balance.

This can be seen from the redshift of distant galaxies - normally attributed to the Doppler effect.
Some nearby galaxies move towards us (blueshift), some move away from us (redshift). Galaxies that are farther away all move away from us (redshift); this means that the Universe is expanding.
Yes, there is proof. The universal redshift that appears in all distant electromagnetic spectra proves that the universe is expanding.

Yes; it is expanding right now, as can be seen in the redshift of distant galaxies.

cons quasars have have large red shift that suggest they are far away as distant galexies some quazars with very high redshifts appear to be interacting with other galexies that have lesser redshift which would suggest that quazars have ann in trensic redshift pros its perfect evidence to show that the universe is expanding
