Extent and thickness is two different things. Just look how your ice cubes freeze. So those pictures may be deceiving.

And 50 years?? What the hell is 50 years in relation to the age of the universe.

I don’t think they are thinking of as 50 years showing significance for all time. The point is that it showed dramatic change in short periods of time (2 years) which shows how much we don’t know. It takes some of the wind out of the sails of those who claim to know it all (even without all the data).
