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

 

Answer the following questions.

1. When did Albert Einstein first talk about the waves?

2. What things must hit each other in space for the waves to form?  

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?

Listen to a part of the story again and complete the sentences below.

It took __o___h____(1) years, but finally, scientists proved Albert Einstein’s theory that gravitational waves e__________(2). The waves were predicted as part of Einstein’s General Theory of Relativity nearly 100 years a_______(3).
