Quran On Time Dilation And Relativity
Velocity Time Dilation

One of the most revolutionary concepts that we learned in the 20th century is that time is not a universal measurement. The rate at which it passes depends entirely on your speed and acceleration at any given moment. In Einstein’s theory of relativity, time dilation describes a difference of elapsed time between two events, as measured by observers that are moving relative to each other. Basically, it states that the faster we go, the more the time is affected and almost stops for somebody moving at a speed close to the velocity of light.

In order to attempt to prove this theory of time dilation, two very accurate atomic clocks were synchronized and one was taken on a high-speed trip on an airplane. When the plane returned, the clock that took the plane ride was slower by exactly the amount Einstein’s equations predicted. Thus, a moving clock runs more slowly when viewed by a frame of reference that is not in motion with it.


Gravitational Time Dilation

Also, the general theory of relativity tells that time is slower in the fields of greater gravitation. A man walking on the surface of the moon will see that his clock runs more quickly as compared to Earth same is with his biological functions and all motions at the atomic and subatomic level.
Time is therefore a relative conception. Now look that almost 1400 years ago this is what the Quran told us in Surah Hajj 22:47, Surah Sajdah 32:5 and in Surah Maarij 70:4. Quran had already included information about time’s being relative. Hours differ and days are conceived differently according to the medium, place, and speed involved.

٤٧ وَيَسْتَعْجِلُونَكَ بِالْعَذَابِ وَلَنْ يُخْلِفَ اللَّهُ وَعْدَهُ ۚ وَإِنَّ يَوْمًا عِنْدَ رَبِّكَ كَأَلْفِ سَنَةٍ مِمَّا تَعُدُّونَ
And they urge you to hasten the punishment. But Allah will never fail in His promise. And indeed, a day with your Lord is like a thousand years of those which you count. 22: 47
٥ يُدَبِّرُ الْأَمْرَ مِنَ السَّمَاءِ إِلَى الْأَرْضِ ثُمَّ يَعْرُجُ إِلَيْهِ فِي يَوْمٍ كَانَ مِقْدَارُهُ أَلْفَ سَنَةٍ مِمَّا تَعُدُّونَ
He arranges [each] matter from the heaven to the Earth; then it will ascend to Him in a Day, the extent of which is a thousand years of those which you count. 32:5
٤ تَعْرُجُ الْمَلَائِكَةُ وَالرُّوحُ إِلَيْهِ فِي يَوْمٍ كَانَ مِقْدَارُهُ خَمْسِينَ أَلْفَ سَنَةٍ
The angels and the Spirit will ascend to Him during a Day, the extent of which is fifty thousand years. 70:4
Another Perspective Of Time Relativity

Time relativity is also mentioned in the Quran in another sense. As mentioned below that when mankind will be resurrected then they will think that they stayed in the Earth for a brief period and secondly even after lapses of millions/billions of year since their death they would not feel anything just as we don’t feel that we are born after billions of year of the birth of this Universe.

Surah Taha 20:102-104
١٠٢ يَوْمَ يُنْفَخُ فِي الصُّورِ ۚ وَنَحْشُرُ الْمُجْرِمِينَ يَوْمَئِذٍ زُرْقًا
١٠٣ يَتَخَافَتُونَ بَيْنَهُمْ إِنْ لَبِثْتُمْ إِلَّا عَشْرًا
١٠٤ نَحْنُ أَعْلَمُ بِمَا يَقُولُونَ إِذْ يَقُولُ أَمْثَلُهُمْ طَرِيقَةً إِنْ لَبِثْتُمْ إِلَّا يَوْمًا
The Day the Horn will be blown. And We will gather the criminals, that Day, blue-eyed.
They will murmur among themselves, “You remained not but ten [days in the world].”
We are most knowing of what they say when the best of them in manner will say, “You remained not but one day.”
Surah Yunus 10: 45
……. ٤٥ وَيَوْمَ يَحْشُرُهُمْ كَأَنْ لَمْ يَلْبَثُوا إِلَّا سَاعَةً مِنَ النَّهَارِ
And on the Day when He will gather them, [it will be] as if they had not remained [in the world] but an hour of the day….
