Abstract
The seven Chapters of Part 2 of this book reveal the extent of the unbelievable progress of physics since the beginning of the 20th Century. However, despite this success, there remain many open problems. Among these are the inconsistencies between QM and Relativity, the history of the early universe, the unknown nature of dark matter and dark energy, and the possible existence of a multiverse. In this Chapter, several plausible scenarios for future developments are proposed. Others, unheralded here, will also undoubtedly appear, as new ideas are explored by bright new minds in a future for physics that promises to be every bit as exciting as the past.

Notes
- 1.
The bard was paraphrasing the much older: Nothing can be made from nothing—once we see that's so, already we are on the way to what we want to know.—Lucretius, De Rerum Natura, 1.148–156.

Exoplanets are planets that orbit a sun in another solar system, and not our sun.
