The Big Bang theory is the most accepted theory for the creation of the Universe. The Big Bang theory is the first model for the development of Universe wherein the matter in it, space, and time were formed from a huge cosmic singularity. The theory indicates that from the 13.7 Billion year ago, it has gradually expanded into a very tiny but extremely hot and dense cosmos see in today’s telescopes, to the vast but diffuse Universe we see around us today.
When astronomers study the skies and the universe, they note that it seems there must have been a massive explosion of mostly hydrogen, helium and stars. This occurred about the 13.8 billion years after the beginning of the universe. Scientists use this time period to place bets on where the next explosions might be. This hypothesis also proposes that somewhere within our galaxy or beyond, a super giant hole is forming.
The big bang theory can also be used to explain the creation of black holes. Astronomers have detected these holes with the help of Very Large Telescopes (VSTs) and infrared imaging and found that they tend to rotate in anti-clockwise spirals. These spirals are similar to what astronomers call ‘planetary nurseries’ as they are made of disks of gas moving through different processes within our Galaxy. It was also noted that when such disks collide, they give off shocks that create very high intensity radio waves, which are picked up by the orbiting satellites orbiting the Earth.
Based on the predictions of the big bang, astronomers suggest that shortly after the universe began to evolve, the first stars were produced. These stars had a very low density but very high temperatures and they existed for around ten million years before they exploded. The debris from the explosions then merged together and formed the first planets. This theory suggests that the creation of life began when the first planets were born and that the life span of these planets was brief as compared to the age of the first stars.
If the big bang theory is correct, it means that our present age began when the first stars went out into space. But does this mean that after that, nothing happened? Not at all! The Big Bang Theory can also explain many other phenomena that are observed in our daily lives. For example, astronomers nasa have identified several large celestial objects that have extremely distant surface areas. They orbit very close to the very edge of the solar system and they possess very low gravity.
Some of these objects have very strange surface structures which are very unlike the normal star formation that we observe. These objects have very hot temperatures, which suggests that they were in a hot soup of plasma, before the big bang. Furthermore, the composition of these objects shows that they are made up of heavy elements such as carbon. When astronomers nasa study the composition of comets and other small icy bodies they find that the composition is very similar to the composition of the cosmic microwave background radiation. These similarities are further buttressed by the fact that the temperatures of comets are very close to those of the cosmos.
These ideas about the origins of the universe are also buttressed by models of the universe that are currently in use at NASA. In their model, the universe is made up of multiple filaments of expanding gas which were once much cooler but expanded to become the web that we observe today. These models also imply that there are a lot of stars in the universe which were formed from the collisions between these smaller cold gas bubbles. The models also show that there are several super huge voids that are capable of giving off gravitational waves. All these features make the cosmic microwave background radiation a very important tool in the study of the origins of the universe.
An alternative to the big bang theory is the idea of inflation. This idea says that the universe was created through an unaided inflation process where nothing left alone by itself to form the first stars, planets and galaxies. It also says that the rate of expansion of the universe was very fast during the big bang stage, which caused the first visible elements to form. Some scientists think that inflation may be present in some more primitive forms of life forms that existed in the early universe.
