1400 years back people had no idea about the boundary of the universe. But even at that time in the Holy Quran a challenge is given that man will never be able to cross the boundaries of the universe. challenge of The Qur’an
The boundary of the universe and a challenge of The Qur’an
O jinn and mankind, if it is within your power to cross the boundaries of the heavens and the earth, then cross. But you cannot cross it without a permit. [Surah Ar-Rahman – 55:33].
In Surah Ar-Rahman verse 33 a challenge is given that man will never be able to cross the boundaries of the universe. It is very surprising. It is not possible for humans to overcome this challenge but we are all sure today. However, when the Holy Quran was revealed, people had no idea about the extent or boundaries of the universe. The people of that time had no idea about how far away the stars and planets are in the night sky. Since the invention of the telescope, man began to have some idea of the distance between the first planets and stars. Around 1609, the scientist Galileo Galilei first started using telescopes to observe space. In 1925, Edwin Hubble discovered the nearest galaxy to us, which is called Andromeda Galaxy. The nearest galaxy to us is estimated to be about 2.5 million light-years away. That is, even if it runs at the speed of light, it will take 2.5 million years to reach the nearest Andromeda galaxy. That means that humans will never be able to reach the nearest galaxy. Not to mention galaxies billions of years away. challenge of The Qur’an
The boundary of the universe and a challenge of The Qur’an

Traveling at the speed of light to the center of our own galaxy would take 26,000 light years to reach. So it is not possible for us to cross the boundaries of creation even in the fastest rocket. In general, throwing a challenge despite having no idea about the vastness of space for 1400 years proves that the Holy Qur’an is actually not a human-written book, rather it is a book revealed by Almighty Allah, who has a complete understanding of the boundaries of the universe.
