In Cosmic Jackpot, Davies argues that certain universal fundamental physical constants are precisely adjusted to make life in the Universe possible: that we have, in a sense, won a "cosmic jackpot," and that conditions are "just right" for life, as in The Story of the Three Bears. As Davies writes elsewhere, "There is now broad agreement among ...
That N = 3 and T = 1, setting aside the compactified dimensions invoked by string theory and undetectable to date, can be explained by appealing to the physical consequences of letting N differ from 3 and T differ from 1. The argument is often of an anthropic character and possibly the first of its kind, albeit before the complete concept came ...
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.
Physics World editor Hamish Johnston pointed out that while some scientists might be concerned at the book potentially emboldening doubters of the scientific method, Hossenfelder's desire to offer a "better understanding of the limitations of science" is provided "loud and clear" and made them "think about the scientific method and the big ...
On reddit, I once had a man explain to me in detail that finding women’s clothes with pockets is not difficult at all. The topic in question involved 17/18 year old girls going to a school ...
This view treats the cosmological constant as simply another fundamental physical constant not predicted or explained by theory. [15] Such a renormalization constant must be chosen very accurately because of the many-orders-of-magnitude discrepancy between theory and observation, and many theorists consider this ad-hoc constant as equivalent to ...
