Opinion | The Webb Space Telescope is telling humanity the history of everything <https://www.washingtonpost.com/opinions/2023/01/28/astonishing-james-webb-space-telescope/> ( TNCR). I am happy that Hubble opens up a vision towards iNdia. It was 13 billion; but Einstein :trillions" in the past and the future as we are saying 550 trillions. Space and time and the photons' views are changing. And most of all I like Nat King Cole sitting in front of Radio Novak set in the night 10 30 PM, when all will be sleeping and with the least sound and ears close to the radio-set, listening in December Chakrapani the news reader cum english music Madras station B announcer blaring from nat king cole at my 17 years old. Stardust is later. but his xmas carol is famous. 1 https://youtu.be/Xxe2LP_bNiI 2 https://youtu.be/Z57yI62PUys ( MSV copied in KADALIKKA NERAMILLAUI the opening tune for ANUBHAVANM PDUMAI MIXING COLE AND BESSAMI MOUCHO) 3 https://youtu.be/f_HmF84G7ZY Love 4 https://youtu.be/HcRQiNHrsoQ very thought of you. tHANK YOU FOR ALL kr irs 31123
