Cross through the karst cave to reach the otherworldly Lightyear Beyond Hotel

This is my favorite hotel on my trip to Guizhou so far, with the beautiful name "Lightyear Beyond." Pass through a 300m-long dark karst cave, and suddenly the view opens up as if you've entered an otherworldly paradise. The wooden structure and warm colors seem to carry the comfort of the green hills and clear waters in every inch. The sound of cicadas filters through the window screen. Here, you can be engrossed or distracted. The only thing that can disturb us is the evening breeze blowing from the valley. At night, in addition to the sound of rain knocking on the banana leaves, I also heard sounds from outer space 13.7 billion light years away at the base. I've always wondered why this hotel doesn't have strict security checks, but it blocks our cell phone signals and provides Wi-Fi. Later, I learned that all of the more than 900 pulsars that the FAST telescope has detected so far, the sum of all the electromagnetic pulse signals, is not enough to turn a page of a book. Such weak energy can be disturbed by even the slightest cell phone signal. Generation after generation of captains have turned their eyes to the distant universe, exploring the galaxy, searching for new worlds, discovering new civilizations, and bravely venturing into places where no one has gone before. Although that's in the movies, and we can't travel between stars yet, mapping pulsar spectra is used for future space travel, and the principle is the same as navigation and positioning. On one side is the radio telescope, which represents the world's highest technology, and on the other is a secluded secret place in the wilderness. The documentary "Wonders of the Universe" says that every atom in my body and yours comes from the same matrix billions of light years away, at the beginning of the universe. We are closely dependent on each other, and even if we are far apart, time will allow us to overlap each other, and life will never cease. We have no way of knowing what kind of world is out there, but that doesn't stop us from continuing on our journey to the stars...
