Today, most believe that the Universe began with a Big Bang which occured about 14 billion years ago. At that time, the entire Universe was inside a bubble that was thousands of times smaller than a pinhead which was hotter and denser than anything we can imagine.
Then it suddenly exploded which is why the Universe we are part of today was created. Time, space and matter all began after the Big Bang occured. In a fraction of a second, the Universe grew from smaller than a pinhead to bigger than a Galaxy and it kept on growing. The Universe is still expanding today.
The Qur’an amazingly mentions both the creation of the Universe and the continuous expansion.
The Qur’an mentions:
“Did not the disbelievers observe that the heavens and the earth were together, so We parted them, and we made every living thing from water? So will they not accept faith?” (Quran, 21:30)
Other translations of the above verse:
Sahih International: Have those who disbelieved not considered that the heavens and the earth were a joined entity, and We separated them and made from water every living thing? Then will they not believe?
Pickthall: Have not those who disbelieve known that the heavens and the earth were of one piece, then We parted them, and we made every living thing of water? Will they not then believe?
Yusuf Ali: Do not the Unbelievers see that the heavens and the earth were joined together (as one unit of creation), before we clove them asunder? We made from water every living thing. Will they not then believe?
Shakir: Do not those who disbelieve see that the heavens and the earth were closed up, but We have opened them; and We have made of water everything living, will they not then believe?
Muhammad Sarwar: Have the unbelievers not ever considered that the heavens and the earth were one piece and that We tore them apart from one another. From water We have created all living things. Will they then have no faith?
Mohsin Khan: Have not those who disbelieve known that the heavens and the earth were joined together as one united piece, then We parted them? And We have made from water every living thing. Will they not then believe?
Arberry: Have not the unbelievers then beheld that the heavens and the earth were a mass all sewn up, and then We unstitched them and of water fashioned every living thing? Will they not believe?
The expansion of the Universe is detailed in post Universe Is Expanding
This was another verse which amazed me. The Qur’an seems to mention the Big Bang in a nutshell over 1400 years ago.
