MF,
That summary of Steven Weinberg on the present state of understanding the universe is superb. Notice that he doesn’t have to use any formula in his explanations. He is one of the world’s foremost cosmologists and has great skills of interpretation.

Changes in comprehending the laws of physics generally only occurs at the frontiers of knowledge where further fundamental research or data may be required to verify postulates or otherwise. Thankfully CWE doesn’t have to do any of that. Newton’s Laws, effects of gravity, structural strengths and similar simple things are well known and are not going to change. Use of some novel materials and the development of compact systems, all at a competitive cost basis is the determining issue for CWE.
