Tốc độ của sóng hấp dẫn bị tính sai rồi ạ ???. Mời bạn vào trang bách khoa toàn thư wikipedia để tra thông số của sóng hấp dẫn bằng cách tra từ khoá tìm kiếm : " Quan sát sóng hấp dẫn lần đầu tiên" vào trang tìm kiếm google nhé. Tại trang thống kê này cho ta biết rằng quãng đường phát ra nguồn sóng hấp dẫn này là : 1,3 tỷ năm ánh sáng = 1,3*10^9*365*24*60*60*300000= 1,22*10^22(km). Thời gian phát sóng hấp dẫn này là 0,2 s. Do đó, ta có tốc độ sóng hấp dẫn này là : quãng đường/thời gian = 1,22*10^22/0,2 = 6,14*10^22 (Km/s) chứ ạ !!!. Thế mà các nhà khoa học tính tốc độ sóng hấp dẫn này bằng hằng số c = 300.000 (km/s) thôi ạ. Tốc độ này thì lớn hơn rất nhiều hằng số c chứ ạ . Tôi nói thế có đúng ko ạ ???. Xin cảm ơn !!!.
