每当说起外星人,我们的脑海中总会浮想联翩:有触须的猛兽,皮肤苍白、瘦骨嶙峋的类人怪物,或者是释放纯净能量、微微发光的生物。由于科学家仍未找到有关外星人体貌特征的证据,所以谁也想象不出,人类真的与外星人面对面时将会是怎样一番情景。尽管如此,科学家还是对可能存在于遥远世界的外星生命的特征进行了大胆的猜测。
Whenever we talk about aliens, our minds are always imaginative: beasts with tentacles, skin pale, skinny people like monsters, or creatures that release pure energy and shimmeres. As scientists have yet to find any evidence of the physical appearance of the aliens, no one can imagine the kind of scene that humans would really encounter with the aliens. In spite of this, scientists are still bold speculation about the characteristics of extraterrestrial life that may exist in far-flung worlds.
