Davies also discusses a number of other ideas connected with the "multiverse."Much like a pencil falling to the ground from its tip in a trade off of symmetry for stability, Davies writes that the Big Bang could have established a complex but stable universe (or multiverse) from symmetry breaking as the heat radiation in "space" lowered abruptly past the Curie Point.
The following is a list of notable unsolved problems grouped into broad areas of physics. [1]Some of the major unsolved problems in physics are theoretical, meaning that existing theories seem incapable of explaining a certain observed phenomenon or experimental result.
[1]: 6 Finding a theory of everything is one of the major unsolved problems in physics. [2] [3] Over the past few centuries, two theoretical frameworks have been developed that, together, most closely resemble a theory of everything. These two theories upon which all modern physics rests are general relativity and quantum mechanics.

[note 1] While singling out the currently observable kind of carbon-based life, none of the finely tuned phenomena require human life or some kind of carbon chauvinism. [ 3 ] [ 4 ] Any form of life or any form of heavy atom, stone, star, or galaxy would do; nothing specifically human or anthropic is involved.
Hard science and soft science are colloquial terms used to compare scientific fields on the basis of perceived methodological rigor, exactitude, and objectivity. [1] [2] [3] In general, the formal sciences and natural sciences are considered hard science, whereas the social sciences and other sciences are described as soft science. [4]
The Flying Circus of Physics by Jearl Walker (1975, published by John Wiley and Sons; "with Answers" in 1977; 2nd edition in 2007), is a book that poses and answers 740 questions that are concerned with everyday physics. There is a strong emphasis upon phenomena that might be encountered in one's daily life.
