Hello friends, I am participating in this wonderful Art and Science special where LMAC and STEMsocial join forces to give us the opportunity to make a different collage where the main theme is Dark Matter, for which I had to do some research about it since I don't know the subject. I understood that Dark Matter does not interact with anything and are like ghost particles in the vast universe. Thank you @shaka for the opportunity you give us with an excellent topic.
