XI. Read the passage carefully, then do the tasks. GIẢI THÍCH GIÚP MÌNH NHÉ Scientists say it could take at least 1,500 years before humans make contact with species of aliens, or for them to communicate with or find us. Astronomers from Cornell University in the USA combined two existing theories about the possibility of life existing on other planets to form a new equation. One of these theories is the Fermi Paradox described by physicist Enrico Fermi in 1950. This States that while billlons of Earth-like planets exist in our galaxy, not One has made contact with Earth yet. The other is the principle, which suggests that because there is life on Earth, it will typically exist on Earth-like planets throughout the universe. We havent heard from aliens yet, as space is a big place, but that doesnt mean no one is out there, study author and Cornell astronomy student Evan Solomonides said. According to Solomonides, extraterrestrials could have received signals from Earth. However, he suggests that ET would not have been able to decode them. He said they would need to decode the light waves into sounds and analyse 3,000 human languages to understand any messages. He said that signals from Earth have only reached about 8,500 stars and that the Milky Way galaxy alone contains 200 billion stars. He added: If we stop listening or looking, we may miss the signals, so we should keep looking.

A. Decide whether the following statements are true (T) or false (F).

1. Scientists say humans are unlikely to hear from aliens for at least 1,500 years.

2. Cornell astronomers examined 20 different theories on whether aliens exist. 3. One theory that was looked at was from a physicist.

4. Another theory said there is life on Earth so there will be on other planets.

5. Solomonides said aliens couldnt receive signals from Earth as space is a big place.

6. He said aliens would need to decode 3,000 languages to understand human message.

7. So far Earths broadcast signals have reached around 8,500 stars.

8. The researcher suggested we stop looking for alien life.
