The entire universe is manifesting His attributes and qualities, which are not limited to 99 or any number. That is how Allah is showing Himself to you through many dimensions, whatever you can or cannot think of. Today, science is still in its cradle. We have not researched every aspect of science yet. Scientists only know what they can perceive through the instruments they have invented. They know the elements, atomic structure, subatomic particles, etc. But below these levels there are deeper levels yet to be discovered and studied. Allah has many dimensions of things. There is always more!
