  • Is Everything Made of Mini Black Holes? پنج‌شنبه 31 اردیبهشت‌ماه سال 1388 17:53
    In 1971 physicist Stephen Hawking suggested that there might be “mini” black holes all around us that were created by the Big Bang. The violence of the rapid expansion following the beginning of the Universe could have squeezed concentrations of matter to form miniscule black holes, so small they can’t even be seen in...
