真空磁悬浮系统将替代火箭早在100多年前,科学家就通过计算预测,如果从地面上向太空中发射一枚高速炮弹,当炮弹的速度达到每秒7.9公里的“第一宇宙速度”时,炮弹不再落回地面,而环绕地球作圆周飞行。这也是设计近地轨道飞行器(如人造卫星、空间站)的理论基础。也就是说,任何物体都可以在太空中翱翔,只要能把它的速度加到“第一宇宙速度”。同样,要让火车飞 As early as more than 100 years ago, scientists have calculated that if a high-speed projectile was launched into space from the ground and the projectile's velocity reached 7.9 km per second at “first cosmic velocity” , The shells no longer fall back to the ground, but fly around the earth in a circle. This is also the theoretical basis for the design of near-Earth orbit vehicles (such as satellites and space stations). In other words, any object can fly in space, as long as its speed can be added to “first cosmic speed ”. Again, let the train fly
