Interstellar matter

Interstellar matter

Space outside organized astronomical system was earlier assumed to be a vacuum. Astrophysicists later discovered the presence of bridges of matter in this interstellar space. These bridges of matter are called plasma, and consist of completely ionized gas containing equal number of free electrons and positive ions. Plasma is sometimes called the fourth state of matter (beside the three known states viz. solid, liquid and gas). The Qur’an refers to the presence of this interstellar material in the following verse:

“He who created the heavens and the earth and all that is between.”   [Al-Qur’an 25:59]

It would be ridiculous for anyone to even suggest that the presence of interstellar galactic material was known 1400 years ago!
