到宇宙的其他地方建立生活点,是地球人长期以来梦寐以求的愿望。对此,科学家们提出了许多令人神往的设想。美国宇航局就设计了几类“宇宙岛”方案,为人类勾画出一幅幅美妙蓝图。地球悬于太空中,是一个巨大圆球,它具备特殊的优越条件,致使几百万种生物能在该星球上安家乐业。科学家们正是以地球为蓝本,设计了“宇宙岛一号”。它是一个直径为500米的空心巨球。球的内壁有住宅、树林、河流等。将这个人造太空球放入宇宙,它每分钟自转两周,在“赤道”处产生几乎与地球相同的引力,生活在其中的人感觉象在地球一样。不过,“宇宙岛一号”的引力会随“纬度”增大而减
Establishing a point of life in other parts of the universe is a dream long cherished by the Earth’s people. In response, scientists made many fascinating ideas. NASA has designed several “Island of Universe” programs that outline a blueprint for humankind. Hanging in space, the Earth is a giant ball that has exceptional conditions that allow millions of species to settle on the planet. It is precisely because of the earth that scientists design the “Universal Island One.” It is a hollow giant ball 500 meters in diameter. The inner wall of the ball has residential, woods, rivers and so on. Putting the man-made space ball into the universe, it rotates two rotations per minute, producing almost the same gravity on the equator as the Earth, and the people living in it feel like the earth. However, the gravitational force of “Universal Island One” will decrease as latitude increases
