Henrietta Swan Leavitt discovered an important relationship between the changing brightness of so-called variable stars and the duration, or period, of their light fluctuations. Leavitt gained little notoriety for it in her lifetime, but this observation proved so fundamental to later discoveries about our place in the cosmos that a number of scholars, including renowned astronomer Edwin Hubble, considered it worthy of a Nobel Prize.
Time Is of the Essence… or Is It? What is time? Isaac Newton described it as absolute, but Einstein proved that time is relative, and, shockingly, that time and space are intricately interwoven. Now recent work in string theory and quantum gravity suggests that space and time may not be fundamental. If this is true, what new picture of reality will emerge?
