Finally, in part 3, I discuss the big freeze and what scientists now see as the end of our universe. I also give a serious though speculative, discussion of how an advanced civilization in the distant future might use the laws of physics to leave our universe trillions of years from now and enter another, more hospitable universe to begin the process of rebirth, or to go back in time when the universe was warmer.
From the preface of Parallel Worlds by Michio Kaku.
The very idea of parallel universes was once viewed with suspicion by scientists as being the province of mystics, charlatans, and cranks. Any scientist daring to work on parallel universes was subject to ridicule and was jeopardizing his or her career, since even today there is no experimental evidence proving their existence...But recently, the tide has turned dramatically, with the finest minds on the planet working furiously on the subject.
