In the News (from Newsweek Magazine): “The latest developments in cosmology point toward the possibility that our universe is merely one of billions.
“In Einstein’s day, the possibility that our universe could have turned out differently was a mind-bender that physicists might have bandied about long after the day’s more serious research was done. But recently, the question has shifted from the outskirts of physics to the mainstream.
“And rather than merely imagining that our universe might have had different properties, proponents of three independent developments now suggest that there are other universes, separate from ours, most made from different kinds of particles and governed by different forces, populating an astoundingly vast cosmos.
“The multiverse, as this vast cosmos is called, is one of the most polarizing concepts to have emerged from physics in decades, inspiring heated arguments between those who propose that it is the next phase in our understanding of reality, and those who claim that it is utter nonsense, a travesty born of theoreticians letting their imaginations run wild.
“Remarkably, mathematical analysis also revealed—and here’s where the multiverse enters—that as space expands the cosmic fuel replenishes itself, and so efficiently that it is virtually impossible to use it all up. Which means that the big bang would likely not be a unique event. Instead, the fuel would not only power the bang giving rise to our expanding realm, but it would power countless other bangs, too, each yielding its own separate, expanding universe. Our universe would then be a single expanding bubble inhabiting a grand cosmic bubble bath of universes—a multiverse.
“Through years of painstaking observations of distant galaxies, the teams collected data on how the expansion rate of space has changed over time. And when they completed the analysis, they all nearly fell out of their chairs. Both teams found that, far from slowing down, the expansion of space went into overdrive about 7 billion years ago and has been speeding up ever since.”
My Comment: Kabbalah says that everything is perceived in a person, in his property to receive, and to feel a different universe means to accept its qualities, to give, instead of the present one, to receive. Kabbalah presents us with this opportunity.
