Parallel Worlds: A Journey through Creation, Higher Dimensions, and the Future of the Cosmos Quotes

“Inflation is continuous and eternal, with big bangs happening all the time, with universes sprouting from other universes. In this picture, universes can “bud” off into other universes, creating a “multiverse.” In this theory, spontaneous breaking may occur anywhere within our universe, allowing an entire universe to bud off our universe. It also means that our own universe might have budded from a previous universe. In the chaotic inflationary model, the multiverse is eternal, even if individual universes are not. Some universes may have a very large Omega, in which case they immediately vanish into a big crunch after their big bang. Some universes only have a tiny Omega and expand forever. Eventually, the multiverse becomes dominated by those universes that inflate by a huge amount. In retrospect, the idea of parallel universes is forced upon us.”

“Our Sun is not Earth’s true “mother.” Although many peoples of Earth have worshipped the Sun as a god that gave birth to Earth, this is only partially correct. Although Earth was originally created from the Sun (as part of the ecliptic plane of debris and dust that circulated around the Sun 4.5 billion years ago), our Sun is barely hot enough to fuse hydrogen to helium. This means that our true “mother” sun was actually an unnamed star or collection of stars that died billions of years ago in a supernova, which then seeded nearby nebulae with the higher elements beyond iron that make up our body. Literally, our bodies are made of stardust, from stars that died billions of years ago.”

“The mind reels when we realize that, according to this interpretation of quantum mechanics, all possible worlds coexist with us. Although wormholes might be necessary to reach such alternate worlds, these quantum realities exist in the very same room that we live in. They coexist with us wherever we go.”

“The advantage of this interpretation is that we can drop condition number three, the collapse of the wave function. Wave functions never collapse, they just continue to evolve, forever splitting into other wave functions, in a never-ending tree, with each branch representing an entire universe. The great advantage of the many worlds theory is that it is simpler than the Copenhagen interpretation: it requires no collapse of the wave function. The price we pay is that now we have universes that continually split into millions of branches.”

“To a physicist, beauty means symmetry and simplicity. If a theory is beautiful, this means it has a powerful symmetry that can explain a large body of data in the most compact, economical manner. More precisely, and equation is considered to be beautiful if it remains the same when we interchange its components among themselves.”

“For any reasonable value of Omega at the beginning of time, Einstein’s equations show that it should almost be zero today. For Omega to be so close to 1 so many billions of years after the big bang would require a miracle. This is what is called in cosmology the finetuning problem. God, or some creator, had to “choose” the value of Omega to within fantastic accuracy for Omega to be about 0.1 today. For Omega to be between 0.1 and 10 today, it means that Omega had to be 1.00000000000000 one second after the big bang. In other words, at the beginning of time the value of Omega had to be “chosen” to equal the number 1 to within one part in a hundred trillion, which is difficult to comprehend.”

“Think of trying to balance a pencil vertically on its tip. No matter how we try to balance the pencil, it usually falls down. In fact, it requires a fine-tuning of great precision to start the pencil balanced just right so it doesn’t fall over. Now try to balance the pencil on its tip so that it stays vertical not just for one second but for years! You see the enormous fine-tuning that is involved to get Omega to be 0.1 today. The slightest error in fine-tuning Omega would have created Omega vastly different from 1. So why is Omega so close to 1 day, when by rights it should be astronomically different?”

“It from bit.” It’s an unorthodox theory, which starts with the assumption that information is at the root of all existence. When we look at the moon, a galaxy, or an atom, their essence, he claims, is in the information stored within them. But this information sprang into existence when the universe observed itself. He draws a circular diagram, representing the history of the universe. At the beginning of the universe, it sprang into being because it was observed. This means that “it” (matter in the universe) sprang into existence when information (“bit”) of the universe was observed. He calls this the “participatory universe”—the idea that the universe adapts to us in the same way that we adapt to the universe, that our very presence makes the universe possible.”
