All about Universe: Size, distances, comparisons. All these laws of physics are the laws of your Lord by which He is Running His Kingdom.
O assembly of Jinn and Men did there not come to you messengers from among you, narrating to you your Lord’s revelations and telling you that your Lord is one God, and He created you and all this around you. Do you think that all this is created without any creator? Woe to you for what you assume and woe to you for what you believe. You do not have this opinion for the smallest thing around you which you have created. No one among you even the most duffer and ignorant can claim that even the laces of his shoe are designed by its own but for this magnificent universe, you think that it is created by its own.
Look at the universe around you and then look within yourself. Everything is working under established systems. All this is under precise measurements and calculations from the creation of this huge universe and then billions of stars and planets and then the creation of humans on Earth. Look at the size and vastness of the Kingdom of God around you. Only the observable universe is about 90 billion light years in diameter. There are at least 100-200 billion galaxies, each with one hundred to one thousand billion stars. And, there are probably billions of habitable planets in the universe. Lots of stars and planets, roughly ten thousand stars for every grain of sand on earth and 100 thousand planets for every grain of sand on earth. Is this all designed, created, happening and running by its own. Nay, it is all by the Will and command of your Lord. So which of the favors of your Lord will you deny?
All these estimates mentioned above regarding the size of the universe calculated after 1995 Hubble observations and that was the working assessment for the next two decades, until 2016. And now according to Astrophysical Journal over 90 percent of the galaxies in the observable Universe have yet to be studied. The following decade will see a host of new observatories come online. The Hubble’s successor, the James Webb Space Telescope, will be launched into orbit in 2018. So expect the number of galaxies to increase to astonishing trillions in number. For those who do not have any idea of how big this figure is? If you start counting 1,2,3 with normal speed, then it will take almost 25 years day and night to reach a billion count and almost 25000 years to count a one trillion figure. Everything in this vast and magnificent universe is in motion and in perfect harmony with each other. Is this all created and continue to exist on its own. Nay, it is all by the Will and command of your Lord. So which of the favors of your Lord will you deny?
The distances in the universe are so big that you cannot measure in your normal terms. It can only be measured in terms of a light year which is the distance light travels in one year while the speed of light is 300,000 km /sec. This speed is so much that nothing can travel faster than light. In just one second lights travels 7.5 times around our earth. In a year it travels 9.5 trillion Km and is called a light year which is a distance of length, not time. We live in a galaxy wh
