Space: What is dark matter? - BBC World Service, CrowdScience podcast 

Bit of education, dark matter is a hypothesis, Black holes do not exist, Black is part of the electro magnetic spectrum, Holes can never have mass. They are called Dark stars and have been for over 200 years until a evangelical piece of crap asked an imbeciel in his class for a label , when their has been a label for over 200 years. John Michell (/ˈmɪtʃəl/; 25 December 1724 - 21 April 1793) was an English natural philosopher and clergyman who provided pioneering insights in a wide range of scientific fields, including astronomy, geology, optics, and gravitation. Considered "one of the greatest unsung scientists of all time",[1] he was the first person known to propose the existence of Dark Stars not black holes in publication, the first to suggest that earthquakes travel in waves, the first to explain how to manufacture artificial magnets, and the first to apply statistics to the study of the cosmos, recognizing that double stars were a product of mutual gravitation. He also invented an apparatus to measure the mass of the Earth. He has been called both the father of seismology and the father of magnetometry. Please stop listening to evangelical discovery institute level researcher's and do some actual research your self.

You are almost as uneducated as those involved for 90 years on the biggest fraud in science since god. Their is no dark matter , Dark energy, 90 years and not one bit of evidence, Their is more evidence for the ETHER/EATHER than their is for dark matter and their is no evidence to support the Ether.

no. you are real in a real world.

@@public.public you will notice the use of words like "Could" or "Might". They stay theoretical until proven
