In the vast journey of scientific exploration, a gruesome hypothesis is coming into the public eye: we are in a universe of 93 billion light-years in diameter, perhaps not without space, but within a supermassive black hole. This idea, which sounds like the phantom of science fiction, was put forward by a carefully thought-out group of scientists。
The black hole, this mysterious celestial body, is known for its powerful gravity, and even very fast light cannot escape its “magic claws”. Imagine that the light can travel 300,000 kilometres per second, but in the face of the gravity of a black hole, it is as if it were shackled with an invisible shackle and unbreakable. Einstein’s broad relativity reveals the mystery of black holes: when a giant star consumes its internal fuel and is unable to support its own weight, it collapses sharply to the centre until it forms a very small, highly dense feature, from which a black hole is born。
Scientists have come up with the amazing idea that the universe is a black hole because they discover that some of its characteristics are strikingly similar to black holes. The expansion of the universe is like a balloon that continues to blow up, and according to hawking radiation theory, the surface area of a black hole will grow over time, showing a pattern of “growth”, which coincides with the expansion of the universe. There is also a delicate link between the theory of the big bang in the universe and the myth of the black hole. The universe is believed to have begun with an infinite number of singularities, and to have experienced a super-massive explosion before it began to expand and form the universe that we see today. This transformation, from a very small to a very large one, is somewhat similar to the process of black holes falling from stars to wonders。
It is even more surprising that the speed of time within the black hole is very different from that of the outside world. Within the black hole, time seems to have stalled. And there are significant differences between galaxies on the edge of the universe and the speed of our time. This temporal expansion has further galvanized scientists' interest in the “cosmos or black holes” hypothesis. However, the doctrine is not uncontroversial. It was noted that, according to observations of cosmic microwave background radiation, the universe was about 13. 8 billion years old, while black holes were usually formed as a result of the collapse of the core of stars, a process that took much shorter than 13. 8 billion years. Thus, how to form such a large “black hole universe” in such a short time becomes a major challenge to the doctrine。
Despite the many disputes and challenges, the hypothesis of the “cosmos or black holes” undoubtedly provides us with an entirely new perspective to look at the world. If this theory is confirmed, then our knowledge of the universe will change dramatically. We will no longer explore the unknown in an empty universe, but we will pursue the meaning of life and the mystery of the universe in a super-black hole. This hypothesis not only inspires the curiosity of scientists about the mystery of the universe, but also gives us great awe and anticipation of the power of science。
In a world full of unknowns and surprises, scientific exploration never ends. Perhaps one day, a new doctrine will completely subvert our vision of the world. Let us remain curious about the world and boldly explore the unknown. In the process, maybe you can find some little secrets that no one else knows. Let us travel together in the sea of science, in pursuit of the light of truth。
