Singularity

Everything has a beginning. But how did everything begin? What was there before something? You may have been curious to know everything, or not. This post is for the sages who are restless deep down to know everything. However, if you think you know everything, you know nothing and if you think you know nothing, you know something.

To give answers to these fundamental questions, researchers and scientists have traced back space-time to 15 Billion years ago, The Big Bang. To put thing into context, far beyond 4004 BC, the date of the creation of the universe according to the book of Genesis. You may have noticed the word ‘Singularity’ somewhere. Singularity is the point in time where properties like density, temperature and gravity is infinite and the essence of physics does not hold.  Singularity was followed by the Big Bang which is the dominant cosmological model for the universe as we know it. If someone comes up with a better theory which successfully overlaps with the observations till date then I highly doubt anyone will oppose. But for now, singularity and the big bang are the best theories we have to answer the questions mentioned above. Some skeptics may say the universe has been existing since forever and there is no beginning of time. However, that theory does not satisfy the Second law of thermodynamics which states that disturbance of a system increases over time. If there was no beginning, then by now, the universe would have been in total disorder.

The Big Bang explains about how the universe expanded from a very high temperature and density. Modern cosmology was successful in stating that the universe has not stopped expanding since then. But scientists believe that the universe will collapse eventually, but we don’t have to worry for at least twenty billion years. Everything has an end as well.
