Big Bang Theory

The information from the redshift  of galaxies tells us the galaxies are moving away from Earth. Or more precisely space is expanding

You get the idea of the expanding universe by inflating a balloon. Marker pen dots on the balloon move away from each other as the balloon is inflated.

It is really the skin of the balloon that is increasing the distance between the dots.
The actual dots are not getting larger.

Another model of the ending universe is that of baking raisin bread.

As the dough bakes it rises and takes the raisins with it. Each raisin sees the other raisin move away. The individual raisins are not expanding themselves
