Xia You came back to his senses and blinked.

She was glad that Su Xiaonuan had taken the topic away from Chen Ya and her mind could think about other issues normally.

Xia You asked: "Are you talking about the space-time version of the Fermi Paradox?"

"Well, it's called the Fermi Paradox."

"Fermi said that if there are aliens in the universe, then after enough time, humans will definitely be able to observe aliens," Xia You said. "Similarly, if a time machine is invented, then people will definitely be able to meet them.

A person who takes a time machine from the future to the present.”

Su Xiaonuan had a smile on her face and nodded: "So, what do you think?"

"That means there are no aliens in the world." Xia You leaned her head against the car window, "Humanity did not invent the time machine in the end, and perished before it was invented."

Su Xiaonuan said: "Are you afraid?"

"Why be afraid?"

"Why aren't you afraid?"

"Anyway, it will definitely take many years for mankind to perish," Xia You said faintly, leaning against the car window, "Before then, I will have perished, and it is none of my business."

Su Xiaonuan said: "But have you ever doubted that there are some people in this world who seem to be able to predict the future and do amazing things? Have you ever doubted that those people may have traveled from the future?"
