The First Three Minutes attempts to explain the early stages of the universe after the Big Bang.Weinberg begins by recounting a creation myth from the Younger Edda and goes on to explain how, in the first half of the twentieth century, cosmologists have come to know something of the real history of the universe.
A graphical view of the Cosmic Calendar, featuring the months of the year, days of December, the final minute, and the final second. The Cosmic Calendar is a method to visualize the chronology of the universe, scaling its currently understood age of 13.787 billion years to a single year in order to help intuit it for pedagogical purposes in science education or popular science.
This suggests that the universe began very dense about 13.787 billion years ago, and it has expanded and (on average) become less dense ever since. [1] Confirmation of the Big Bang mostly depends on knowing the rate of expansion, average density of matter, and the physical properties of the mass–energy in the universe.
The absurd universe: Our universe just happens to be the way it is. The unique universe: There is a deep underlying unity in physics that necessitates the Universe being the way it is. A Theory of Everything will explain why the various features of the Universe must have exactly the values that have been recorded.
The reason we seem to be alone in the universe might be right beneath your feet, scientists have suggested. For years, scientists have been perplexed by the fact that we have not found any other ...
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 ...
In the middle of the 19th century, the disagreement between scientific evidence about the age of the Earth and the Western religious traditions was a significant debate among intellectuals. [1] Gosse published Omphalos in 1857 to explain his answer to this question. He concluded that the religious tradition was correct.
In physical cosmology, the Big Rip is a hypothetical cosmological model concerning the ultimate fate of the universe, in which the matter of the universe, from stars and galaxies to atoms and subatomic particles, and even spacetime itself, is progressively torn apart by the expansion of the universe at a certain time in the future, until distances between particles will infinitely increase.
