What is an alien ufo like?

The aliens took Castillo upstairs and sat him in front of an instrument that looked like a fluorescent screen. They debugged the screen with two buttons, and then Castillo leaned down to look? Castillo felt dizzy when he saw a huge deep ditch? The UFO man saw that he couldn't stand it and adjusted it again. Then Castillo was so pleasantly surprised that he almost cried out?

It turned out that what he saw was Bogota, the area where he lived, his small building, his children sleeping peacefully in bed, and his German shepherd dog squatting on the ground, wagging his tail, as if barking! He doesn't know at what altitude UFOs fly, and he doesn't know whether people on the ground can see UFOs.

During the conversation, Castillo asked the alien curiously, how can you walk more than 400 light years to reach the earth in such a short time?

You know, according to Einstein's theory of relativity, the speed of light is 300,000 kilometers per second, and any object moving at this speed or above will disintegrate itself and turn into energy? The alien replied that the theory of relativity must be revised three times to grasp the essence of things? They say Einstein just laid a theoretical foundation, and there are some "interstellar flight corridors" that can shorten the distance between constellations? The distance between planets?
