The number of bacterial colonies that grew on exposed petri dishes were counted to determine the amount of contamination over a period of 1, 15, and 30 minutes. The number of . From . Dark Matter .

History in the Making?. 1862: Maxwell found that there should be electromagnetic waves travelling at approximately the (known) speed of light. 1905: Einstein used universal speed of light as foundation of geometric description of physics.
