Discoveries made in astronomy and physics have proven beyond reasonable doubt that indeed, the universe did have a beginning. The key reasoning behind the theory is that the universe is ever expanding. Consequently, in the past, it was hotter and denser.
Then from this void suddenly explodes a universe far smaller than the tiniest speck of dust. And from this speck of dust, this infinite darkness will emerge all of creation.
The entire cosmos began as an incredibly dense primitive atom. Approximately 15 billion years ago this atom exploded with an intense force. This was not a usual blast, but rather an explosion filling all space with all of the particles of the developing universe charging away from each other.
LeMaitre had no data to substantiate his theory; so many scientists ignored his theory. Two years later inEdwin Hubble discovered that galaxies were moving away at high speeds. Imagine the galaxies hurrying away as in a movie; run the movie backwards and after a time all those galaxies will rush together.
The Big Bang symbolizes the instant the universe began, when time and space came into existence and all matter in the cosmos launched into expansion.
Prior to this all four fundamental forces gravity, electromagnetism and the strong and weak nuclear forces were combined. The explosion was one of space within itself. It was not like the explosion of a bomb where fragments are thrown outward LaRocco 1.
The galaxies were not clumped together. During the first second or so of the universe large amounts of energy, known as photons, smashed together and changed their energy into mass.
This caused the four forces to split into their separate identities. As the universe continued to cool, protons and neutrons combined to form helium and other light nuclei. It was not until around one million years after the Big Bang, nuclei and electrons were cool enough to unite to form atoms.
The universe did not start to look as it does today until small deviations in the matter distribution were able to squeeze to form the stars and galaxies as they are known today. The Big Bang Theory does a remarkable job of describing the universe, as it is known today.
It explains the development of the universe, predicting the correct profusion of hydrogen and helium the most common elements in the universe and it accounts for the cosmic background radiation.
Though it was very successful and few scientists doubt its validity, the Big Bang Theory was too simple to be complete. It describes the aftermath of the bang.
The theory expresses how the early, hot dense universe expanded and cooled.The Big Bang Theory Essay Words | 5 Pages. Topic: What are some modern techniques being used to determine the age of the earth?
When it come to the earth, whether it be about its life, time created or life span you can assure there will be many different theories and beliefs. Beyond Falsiﬁability: Normal Science in a Multiverse Sean M. Carroll Why Trust a Theory?, eds.

Th´ebault (Cambridge University Press). 1 Introduction The universe seems to be larger than the part we can see. The Big Bang happened a ﬁnite time ago, and light moves at a ﬁnite speed, so there is only a.
If we had a theory that applied to the ultra-early universe, but gained credibility because it explained, for instance, some features of the microphysical world (the strength of the fundamental forces, the masses of neutrinos, and so forth) we should take seriously its predictions about ‘our’ Big .
The Big Bang theory can best be described as the existing astrophysical model that explains the earliest development of the universe. Discoveries made in astronomy and physics have proven beyond reasonable doubt that .
Either science is a tool to answer practical questions, or it is a tool to satisfy our anxiety over the uncertainty we experience in our existence. If a theory doesn’t make a testable prediction, it isn’t science.
It’s a basic axiom of the scientific method, dubbed “falsifiability” by the 20th century philosopher of science Karl Popper.
