Dark matter is a form of matter that is undetectable by human senses, because it does not interact with any of the four fundamental forces that affect the visible universe (electromagnetism, strong nuclear force, weak nuclear force, and gravity).

Blood travels through the human body at an average speed of about 3 to 4 miles per hour.
