In the previous article, we talked about the beginning of the universe 14 billion years ago. Today, let's move on.
"The Big Bang", astronomer Fred M. That's how Hoyle spoke lightly of the birth of the universe. Maybe "Big Lightning" is a better name, or maybe "Big Crack" is not bad either. 14 billion years ago, nothing existed. Then God laughed. Infinitely dense, infinitely high-temperature energy seeds emerge from the void, spread out into the boundless space, and eventually drift into matter. According to current cosmological thought, this first laugh of creation lasted only one billionth of a billionth of a billionth of a billionth of a billionth of a billionth. The laughter ended, and the universe began to move like a rushing flood gushing out of the floodgates.
Elementary particle physicists and cosmologists sit around and use equations, pencils, and yellow post-it notes to re-establish theories about the first moments of the universe's birth. This is a cosmic scale ambition that deserves our serious attention. They are people who detect quarks and quasars, people who transform matter into energy, people who map the trajectory of particle motion in a millionth of a millionth of a second, people who look for clues fainter than nail scratches on glass. It would be natural for such a person to ask the question: When and where did the universe come into being? How was it born? Finding answers to these questions is, mathematically, like deducing matter in the opposite direction, like reversing the evolution of a galaxy, like stuffing toothpaste back into a hose.
Speculation into the origin of the universe stems from the discovery of the regression of galaxies. That is, the universe is expanding! The space is like a balloon being blown up, or a bread swollen on a pan. As space expands, galaxies become more and more distant from each other like speckled spots on a round balloon or raisins dotted with bread. Interestingly, Einstein predicted this strange behavior of the universe as early as the early 20th century and expressed it in the form of equations of general relativity. These equations seem to firmly believe that the universe is like a dough that is fermenting and expanding. The result was so bizarre and unexpected that Einstein refused to accept it. Thus he added a completely unnecessary constant to the equation, in order to avoid giving such a result, of course, by mixing the simple elegance of mathematics in the process. Later, when Edwin Hubble announced that the universe was indeed expanding, Einstein immediately rushed to the Mount Wilson Observatory to borrow Hubble's telescope to observe the starry sky. It is said that at that time on the mountain, someone explained to Albert Einstein's wife Elsa that the 100-inch (254 cm) aperture giant telescope was used to determine the structure of the universe. "Well, well," Elsa responded, "and my husband did it on the back of an old envelope." What he saw on the observatory impressed Einstein, and he eventually removed the abrupt constant from his equations.
If galaxies are spreading out, they must have been very close. If we played the film upside down, we would see galaxies converging in all directions, accelerating against each other to free up endless void chambers, crushing all the stars like holding a handful of damp sand with their hands. The stars squeeze the stars, matter collides with matter, and the density of the universe is frightening. The film ends in a dizzying, intense glow of pure energy, an endless, extraordinary, nascent universe, which is the beginning of all things.
According to the well-known laws of physics, modern cosmologists can easily calculate the state of the universe at every moment at different historical stages. But physicists and astronomers were desperate to never find out what really happened before the universe was born. What caused the Big Bang? This question must be very tricky, if not meaningless. Cosmic creation is something out of nothing, which seems to violate the conservation laws of matter and energy. But physicists can only shrug their shoulders and say that's the way it is, and then there's no way to explain more.
Later, a new generation of young cosmologists became more and more bold in speculating about the beginning of everything, and were able to glimpse the world before the birth of the universe from their equations. They drew on recent discoveries about the behavior of substances in high-temperature environments. They tweaked theories about space and time, leading us back to quarks and neutrinos, the elusive w and zo particles, and other subatomic elementary particles that make up the modules of the universe. All this knowledge gives us a surprising prediction: our universe, the universe born 14 billion years ago in a fireball formed by the radiation of energy and matter, may be just one of many. The universe may boil like a bubble in a larger hyperspace and hypertemporal matrix, which explodes with quantum perturbations in hyperspace. The positive energy of stars and galaxies is balanced with the negative energy of gravitational potential energy, and all the bubbles of creation add up to zero. Our universe is a bubble that erupts from nothingness without violating the laws of physics, a bubble that envelops our space, our time, our Galaxy, and its endless galactic brethren. If the "magician" who made these calculations is true, then these universes exist all the time, and the night sky where our stars shine is nothing more than the interior of a bubble of galaxies that are constantly creating themselves.
If this content makes you feel dizzy, then I want to congratulate you. Me too.
But there was a strange feeling that made the general read it over and over again, trying to read the strange words. Because, brain burning, is the basic requirement of all great sciences.
When Cozczny discovered that Earth was just one of many planets, when Shengton told us that the Sun was just one star, and when Hubble proved that the Vortex Nebula was another galaxy, their brains would also be dizzy from the violent operation.
The impact of knowledge can be dizzying and resistant, but if you go back and learn to read, the freshness is obsessive.
