Descrição da editora
Since the ancients, physicists have argued that time is not real, that we may think we experience time passing but it's just a human illusion in a timeless universe operating on predetermined laws. Lee brilliantly shows how this thinking came about from our deep need for stability and the eternal, but that indeed time may be the only thing that is real.

PUBLISHERS WEEKLY
Contrary to Plato and Einstein, theoretical physicist Smolin (The Trouble with Physics) asserts that "not only is time real, but nothing we know or experience gets closer to the heart of nature than the reality of time." Though time has always been a quantity to measure, the author explains that in the 17th century, scientists began wondering whether "the world is in essence mathematical or it lives in time." Newton's laws of motion made time irrelevant, and "Einstein's two theories of relativity are, at their most basic, theories of time or, better, timelessness." Galileo and Descartes, on the other hand, insisted that time should be regarded as another dimension, and in 1909, mathematician Hermann Minkowski developed the theory of "spacetime," a feature of the universe shaped by gravity. Smolin asserts that current-day cosmology has hit a wall because physicists refuse to understand that physical laws must "evolve in a real time." Changing that perspective, he says, will revolutionize everything from string theory to the stock market. Although the distinctions in point of view aren't always clear, Smolin makes an energetic case for a paradigm shift that could produce mind-boggling changes in the way we experience our world.

A volta do Tempo
Muito bom ter a orientação de um cientista que discorda da relatividade da simultaneidade de evento. Agora posso ler outros autores com a mesma visão em que o tempo volta a ser fundamental e ver as consequências disso na velocidade constante da luz.
