Một người đàn ông tên Arthur Eddington đã giúp biến Einstein thành một ngôi sao - bằng cách sử dụng các ngôi sao! Đầu tiên Einstein dự đoán rằng khối lượng sẽ bẻ cong không gian và kết quả là đường đi của ánh sáng. Ý tưởng này là một phần của Lý thuyết tương đối tổng quát của ông.

Năm 1919, Eddington đã sử dụng các quan sát để kiểm tra ý tưởng của Einstein trong nhật thực, khi ông có thể đo được vị trí của các ngôi sao theo hướng Mặt trời. Eddington thấy rằng vị trí ban ngày và ban đêm của các ngôi sao dường như khác nhau! Tại sao? Mặt trời tập trung không gian để uốn cong và ánh sao chiếu theo con đường của không gian bị uốn cong. Thí nghiệm này đã chứng minh rằng dự đoán uốn cong ánh sáng của Einstein là đúng, và nó khiến ông nổi tiếng khắp thế giới!

stressful green bad healthy easy happy long

Is life better than it was in the past? Older people look back to when they were younger and complain that young people today don't realise how difficult things were then. Of course, in many ways, life is healthier than now. We live in a word wich is cleaner and safer. It is generally easier as well, and because of the improvements in medical care, both men and women can expect to live longẻ lives. Our day-to-day existence is more comfortable, but are we happier?

The rhythm of life is faster, and more stressful. People are always in a hurry. In the end, it is hard to say if things were better or worse than before.As the saying goes 'the grass is alway greener on the other side of the fence'.
