An author of textbooks on the early Universe and inflation, David Lyth now explains both cosmology and the underlying physics to the general reader. The book includes a detailed account of the almost imperceptible structure in the early Universe, and its probable origin as a quantum fluctuation during an early epoch known as the epoch of inflation.
of creation of the Universe and formation of its large-scale structure. One of the most unexpected consequences of inflationary theory is that quantum fluctuations responsible for galaxy formations sometimes may be powerful enough to create new parts of inflationary Universe, rendering the Universe as a huge eternally growing self-reproducing ...
visible Universe is the size of a grapefruit. 13.7 BILLION YEARS This is where we are today. Using our own ingenuity, humanity is probing the depths of the Universe and trying to unravel its mysteries, from our tiny, home planet, Earth. The visible Universe contains billions of galaxies, each comprising billions of stars. Within our own

The formation of stars • Over the next 100 million years or so, the Universe continued to expand and cool. • Gravitational variations caused matter to clump together and become hotter and denser. • 100–200 million years after the Big Bang, matter began to coalesce and form stars. • Fusion of light elements in stars released energy and formed elements from carbon to iron.

and the universe is 13.7 billion years ago are entirely different. If the universe has an absolute origin it presumably means that it came into being as a result of something either before or outside the universe. None of the options seem to make much sense from a scientific point of view and perhaps not even from a logical point of view.
Cosmology: The History of the Universe . Most galaxies are moving away from us. Hubble* discovered that the Universe is expanding: the recession velocity V of a galaxy is proportional to its distance D, V = H oD, where H o is the Hubble “constant”. Observations: H

The book "Puzzles and Laws of the Universe" is in its essence is a second edition of the scientific essay "Notes about the Universe". The readers are proposed more sophisticated material formulating a new paradigm of physical science, which for the author, provides a possibility to explain many so called "modern puzzles" of the material world.
The Universe—as the Totality of Existence—is not just a physical universe of matter, space, and time, accessible by our five external senses. Indeed, there can be any number of such concurrent and consecutive universes, dying in black holes and emerging again in big bangs, as abstractions from or appearances in Consciousness.

including space itself, was created in the Big Bang. The Universe expanded because the space between the galaxies expanded. • To the galaxies, there is no centre from which expansion occurred. Expansion from a central point could only be evident to an observer ‘outside the Universe’ (but we don’t know that there is such a place).
The history of the universe and how it is grown is accepted as Big-Bang model of the universe. According to Big-Bang model of cosmology, the universe began as incredibly hot, dense point approximately 13.5 billion years ago, which is known to be as the age of the universe. The universe starts
Here the universe was infinitely hot and dense before cooling and inflating. 7. Today’s universe In comparison to the turbulent changes that it went through when growing up, the universe we see today – and that’s pinpointed with galaxies, stars and planets among other structures – is much calmer. 2. Quark soup 3. Big freeze out
Universe keep expanding •All distant galaxies move away but galaxies retain their structure for a long time (100 trillion years) before stars run out of fuel •Galaxies move apart, Stars move apart, Stars break up, Universe filled with dilute gas, dark and cold (50 b y) [Solar system destroyed long before that (7.5b y) Sun heat up in 1b y ]
