I heard a rumor of something very significant that happened last week.
A few kollel guys from Yerushalayim dissected the sac of the Murex and found that it consists of two inner sacs the large one contains a yellow liquid and the small one contains a minute amount of black liquid. When you break the Murex open the sacs also break and they mix.
However, if you carefully seperate the liquids before they mix, only the black liquid makes wool turn blue.
Why is this significant? Because the Rambam says that the liquid coming out of the Hilazon is black like ink.
If this finding is true, then it is another overwhelming proof of the authenticity of Murex as the actual Hilazon according to all understandings of the Rambam.
Can anybody verify if this is actually happened last week?
