The FOX television series Cosmos has attracted a strange scientific controversy once again, but this time it is not over global warming, the Big Bang or even evolution but over the comets that were explained in the most recent episode. Cosmos host Neil deGrasse Tyson discussed what comets are and what they are not.

Before there was any scientific explanation about comets, it was believed that comets were actually warning of doom in different cultures. And the actual word disaster mean 'bad star' in the Greek language.

As the show progressed, Edmund Halley's life story was explained, as he provided significant information about comets and their work. Also, a comet has been named after him and it comes back by the earth about every 75 years. Last time, the comet came in 1986 and now is scheduled again in 2061.

Halley also encouraged Sir Isaac Newton to publish the Principia Mathematica, which is thought to be the most important science book ever.

The controversy was over the most recent episode of Cosmos that sparked doubts among creationists because they do not believe anything in the universe is more than 6,000 years old. However, Tyson stated in the most recent episode that several comets arrive from the Oort Cloud, an extremely far off region of icy figures that lay very far outside of Pluto. But they still orbit the sun.

There is no denying the possibility that over two trillion of these ice-covered objects are in existence. And sometimes, one of them strays and takes a very long travel time to the inner portion of the solar system.

Because of getting closer to the sun, the warmth is provided and the transfer of gas and ice provides it with a tail. If it approaches earth, then humans may get the view of it.

NASA states that the objects in the cloud region are 4.6 billion years old, which is believed to be the time when the solar system was formed. But creationists have a problem here that comets cannot exist for more time than the entire age of creation is. And Oort region is something just imagined by scientists to name a birthplace for comets.
