One of the popular definitions is the big bang cosmology. This is the most recent arguments that try to establish the origin, progress and the future of the universe. It is based on science and is credited for bringing more light in to understanding how the universe operates. According to the big bang cosmology, the universe was not as it is today. It was far much smaller. Billions of years ago, the space that was there got so hot and started expanding. This expansion resulted to an explosion that saw the space disintegrate to many pieces.
The big bang cosmology further tries to explain what
happened after the explosion. The space we are living in today continued
expanding. However, unlike the earlier small space that got too hot, this piece
cooled enough to support life but still went on expanding. There are other pieces
that we can call planets that cooled in exactly the same way as our planet;
some of these planets are inhabitable while others cannot support any life.
There are many things that can make a planet not to support life for example
lack of water or air. Lack of these things is what makes some planets habitable
while others are not.
The big bang cosmology states that there are some pieces
that are still very hot and continue expanding every day. These pieces can be
seen going round in the universe. No one really knows what is going to happen
to these pieces. Each piece will react to the condition it is in differently
and no piece is ever similar to the other.
If you read the big bang cosmology carefully, you will most
likely get to understand how the universe came to being and know what is bound
to happen to the universe over time. Sometimes though, it can be hard to
believe that the current universe as we know it was just a tiny piece that
expanded.
You might also wonder what will happen to those other inhabitable
pieces that are still going round the earth. What is going to happen with time?
Are these pieces likely to expand and result in formation of more planets? Are
they going to calm down and become habitable like our planet today?
Most people who rely more on the other cosmology definitions
find the big bang cosmology hard to explain and understand. We are all very
different therefore no one should be limited to any type of thinking .If you
find that the big bang cosmology works for you, well and fine. If on the other
hand it does not, try finding out other cosmology definitions and settle on the
one that best satisfies you.
