We have already seen in the articles
http://secondriseofislam.blogspot.com/2013/04/universe-travel-within-mans-life-span.html that contraction/expansion of space actually means contraction/expansion of Dark Matter. In other words gradual contraction of time on earth as we move from 1st sky to upper skies is due to gradual contraction of Dark Matter as we move from the seventh sky to first sky. In other words, gradual expansion of time- as we move from first sky to upper skies- which results in gradually quicker happening of events on earth is due to gradually more expansion of Dark Matter as we move from first sky to upper skies.
This is the special arrangement made by Allah for man to travel through this universe within man’s life span. This special arrangement provides for such paths which run through such a low density Dark Matter space which may reduce (up to 18250000 times) a time required for an event to happen on earth. Man, treading upon such low density Dark Matter paths, would be able to travel through galaxies within a few years- the galaxies which according to earth time require billions of years to be traversed through.
This relationship between Dark Matter and Time and Space has become more likely to be proved with the discovery of Gravitational Waves a few days back. The scientists say they have detected gravitational waves which impact fabric of Space and Time; these gravitational waves are actually said to be sent through fabric of Space and Time. In other words, these gravitational waves may expand as well as contract Space and Time (just as water waves can expand as well as contract water surface).
In the article http://secondriseofislam.blogspot.com/2013/02/origin-of-universe-and-dark-matter.html and http://secondriseofislam.blogspot.com/2016/02/dark-matter-keeps-everything-alive.html, as has been mentioned above, we have seen that contraction/ expansion of space actually means contraction/expansion of Dark Matter.
This discovery of Gravitational Waves would probably lead to confirmation of relationship between Dark Matter and Time and Space, as has been explained by me in above mentioned articles.
