The Big Bang theory is the prevailing cosmological model for the birth of the universe. It states that at some moment all of space was contained in a single point from which the Universe has been expanding ever since. Modern measurements place this moment at approximately 13.8 billion years ago Malik Hooker Youth Jersey , which is thus considered the age of the universe. After the initial expansion, the Universe cooled sufficiently to allow the formation of subatomic particles, and later simple atoms. Giant clouds of these primordial elements later coalesced through gravity to form stars and galaxies. The Big Bang theory does not provide any explanation for the initial conditions of the Universe; rather T.Y. Hilton Youth Jersey , it describes and explains the general evolution of the Universe going forward from that point on.

Hubble observed that the distances to faraway galaxies were strongly correlated with their redshifts. This was interpreted to mean that all distant galaxies and clusters are receding away from our vantage point with an apparent velocity proportional to their distance: that is, the farther they are, the faster they move away from us Andrew Luck Youth Jersey , regardless of direction. According to the Copernican principle (that the Earth is not the center of the Universe), the only remaining interpretation is that all observable regions of the Universe are receding from all others. Since we know that the distance between galaxies increases today, it must mean that in the past galaxies were closer together. The continuous expansion of the Universe implies that the Universe was denser and hotter in the past.

The Big Bang theory offers a comprehensive explanation for a broad range of observed phenomena Nyheim Hines Youth Jersey , including the abundance of light elements, the cosmic microwave background, large scale structure Tyquan Lewis Youth Jersey , and Hubble's Law. The framework for the Big Bang model relies on Albert Einstein's theory of general relativity and on simplifying assumptions such as homogeneity and isotropy of space. The governing equations were formulated by Alexander Friedmann, and similar solutions were worked on by Willem de Sitter. Since then, astrophysicists have incorporated observational and theoretical additions into the Big Bang model Kemoko Turay Youth Jersey , and its parameterization as the Lambda-CDM model serves as the framework for current investigations of theoretical cosmology. The Lambda-CDM model is the standard model of Big Bang cosmology, the simplest model that provides a reasonably good account of various observations about the Universe.

The earliest and most direct observational evidence of the validity of the theory are the expansion of the Universe according to Hubble's law, discovery and measurement of the cosmic microwave background and the relative abundances of light elements produced by Big Bang nucleo synthesis. More recent evidence includes observations of galaxy formation and evolution Braden Smith Youth Jersey , and the distribution of large-scale cosmic structures. These are sometimes called the "four pillars" of the Big Bang theory.

Precise modern models of the Big Bang appeal to various exotic physical phenomena that have not been observed in terrestrial laboratory experiments or incorporated into the Standard Model of particle physics. Of these features, dark matter is currently subjected to the most active laboratory investigations.

Chocolate is an all time favourite for anybody. No doubt that the variety of this dark temptation liked by each person might differ. There are many varieties of chocolates available in the market. So lets us see just a few of these options:

The fact that makes this one of the most eaten and preferred variety of desert are the hordes of health benefits that comes along with the great taste. One might wonder how can the most fatty thing have health benefits, but it is true that most types of chocolates have great health benefits.

Some of the good points that come along the awesome taste are:

1. Healthy Heart- A recent Swedish study has confirmed it that chocolate has great cardiovascular benefits. Just two servings of dark chocolate per week reduce the danger of heart failure.

2. Lowers High Blood Pressure- A square of dark choco a day acts very effectively in reduces and maintaining the blood pressure. It is because of the flavonoids and antioxidant quality of this sweet that helps in this.

3. Stress Buster- The bars or rolls of this sweet has been a great stress buster and helps in reducing depression since . wholesale air max mens   nike air max 90 wholesale china   Cheap Nike Air Max Shoes   Jordan Shoes For Sale   Nike Air Max 2017 Sale   Cheap Jerseys China   Cheap Jerseys From China   Wholesale Jerseys Free Shipping   Cheap NFL Jerseys China   Cheap Jerseys Wholesale
