Aha ! Thanks.

Quite frankly the rest of the article isn't easy to decipher either (but English isn't my first language).

The list of beliefs/theories that could change throws me off because some statements are about some topics that I thought most were in agreement (eg: the universe is expanding)

> Things will continue to change. Below I have put a few things that I think could change from now into the beginning of the next century.

> - The Universe is not expanding.

The cosmology list is more about fact waiting to happen that expansion of knowledge but I am just a layman.
