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.
a particular multiverse with a "measure", i.e. a well defined "density of universes" (so, for parameter X, one can calculate the prior probability P(X 0) dX that X is in the range X 0 < X < X 0 + dX), and; an estimate of the number of observers in each universe, N(X) (e.g., this might be taken as proportional to the number of stars in the ...
Karl Schwarzschild (German: [kaʁl ˈʃvaʁtsʃɪlt] ⓘ; 9 October 1873 – 11 May 1916) was a German physicist and astronomer.. Schwarzschild provided the first exact solution to the Einstein field equations of general relativity, for the limited case of a single spherical non-rotating mass, which he accomplished in 1915, the same year that Einstein first introduced general relativity.

[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.
It's obviously not what I wanted but that's life. I'm not going to lie. It been an adjustment, but the world continues to spin. And I'm an adult. I have children that are counting on me.
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 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.
