38 Listen to a story “Gravitational Waves Detected, Einstein Is Right” [6]

(file 4.1 or 4.2 for advanced groups)

 

Before you start listening read the vocabulary and look through the questions

ripple – n. рябь, расходящийся волнами, пульсация

predict – v. предсказывать; прогнозировать

detect – v.находить; обнаруживать; открывать;

violent – adj. неистовый; яростный; ожесточённый; отчаянный; сильный

crash - v. сталкиваться; разбиваться на куски; раздробляться

black hole - n. черная дыра

ripple in the fabric of space-time – phrase: волна, проходящая рябью по космическому пространству

spin (v.) - вращать(ся) вокруг продольной оси;

galaxy – n. Галактика

3. What are the gravitational waves like?

4. Can you see the gravitational waves with your eyes?

5. What did the scientists use to find them?

6. What would the discovery of the waves answer?
