While reading up a bit in preparation for my interview later today with Ottawa University Professor Rajendra Gupta about the doubling of the age of the universe as part of his latest paper, I was yet again fascinated by the "tired light" hypothesis. Although the hypothesis was first proposed by the Swiss astronomer Fritz Zwicky in 1929 and has over the decades met with great skepticism in the physics community, Prof. Gupta has revived it to explain some profound anomalies in the universe as detected by NASA's James Webb Space Telescope (JWST).
One of the anomalies is that the JWST discovered galaxies that were fully formed barely 300 million years after the universe itself was form 13.797 billion years. They seem as mature as billion-year-old galaxies. That blew physicists' minds because how could it be that a universe that young could produce galaxies that mature. Think a fully grown adult being born after just three months.
Dr. Gupta's paper speaks of tired light in an expanding universe. Tired light essentially means that the red shift attributed to the expansion of the universe is because light losing energy as it navigates massive cosmic distances replete with gas, energy and dust. So literally, light gets tired. That fascinating idea promoted these verses just now.
इतनी दूर बसतीं हैं बस्तियाँ सृष्टि में
के रौशनी चलते चलते थक जाती है
हम तक पहुँच तो जाती है लेकिन
ग़ुस्से में लाल सी पक जाती है
