The man claims to have been to the 2749 time tunnel to the future world, and an American man named Black claims that he participated in the U.S. military's top secret "Montauk Project icon" and the famous "Philadelphia Experiment", and they also said that they entered 2749 through a time machine, or even spent only two years in the distant future. Of course, to this day, scientific developments have not yet proven the feasibility of time travel icons;
2, the man claims to have been to the 2749 global warming and the earth into the glacier, according to the earth in the Xiaoice river period of the law, the earth is actually in the cooling stage, Russian scientists believe that the earth's climate has been circulating, although the global temperature is still rising, but the Xiaoice river period is no longer far away.
