Delve into the paradox of modern cosmology: a clash between scientific inquiry and entrenched beliefs, spotlighting the struggle to consider alternative models in the face of conflicting observations
JWST and other telescope raised flag on the following points:
1. Hubble tension
2. Ever increasing redshift observed
3. High redshift and High luminosity
4. Metalicity and carbon evolution
5. Largest galaxy at early universe
6. Milkyway like galaxies and large filaments in early universe
7. unexpected Morphology of galaxy at high and near to us
Hoyle Narlikar theory of gravity resolve all the above observational issues but people belive in standard cosmology. Science is not subject of belive. Observational data should match with prediction .
That's truly a great perspective I gained today after reading this blog, or rather, it boosted my scientific approach. You referred to the "Big Bang Theory" as the most popular theory, not necessarily the most accurate. I believe these crucial points are often overlooked in our university lectures and even in many books.
Thank you Dr. Jayant for sharing your thoughts with the world again. It brings back pleasant memories from my childhood, when our whole family enjoyed watching your sessions.
When I was in high school, reading through the books of physics, chemistry and biology used to give me immense joy. I felt that we know a lot about our universe and world around us. But based on your blog, it appears as if the scientists made a huge extrapolation based on observations, at least for the big bang. I wonder if there are other such huge jumps in human thought, that require alternative discoveries? What also blows my mind is the acceleration of knowledge in last 100 years. Does suddenly human race become intelligent, appears to be difficult to fathom. Could you please share your thoughts on how did it become possible for humans to study our surroundings at such great depth when all we are born with is 5 senses and curious mind, or is there something more to it that makes people like Newton and Einstein.
Dear Dr. Naralikar, it's wonderful to read your blog. It brought back happy memories from my childhood when we got to learn about science from your programmes. Now, I am going to share this article with my daughter. Thank you and looking forward to reading more from you.
The big bang model: So far as I am aware, the BB model got a boost when microwave background was discovered. But no other evidence is there. For example, a great hype was put on the concept of inflation. Now it seems to have fizzled out. Dark matter has been found but to say that it is nonbaryonic is to make BB survive. Chip Arp and others have found observational evidence inconsistent with Hubble's law. But it is ignored because it will be against BB. See my book “Facts and Speculations in Cosmology” (Co authored with Geoffrey Burbidge).
Thank you Dr. Naralikar. I will certainly read the book you referred to. I want to tell you that my interest as a child in Science was all thanks to your stories. I still briwse theough Yakshanchi Dengi and Preshit some times.
I have a personal question. My daughter is now in 10th grade and starting to become interested in Physics. She currently lives in Sweden. She is curious about space and astronomy as well as creative writing. Can you please suggest any books she can read that helps her grow her interest in the subjects and also encourages her to grow her interest? Thank you sir for your guidance.

I find it unrealistic that we should have got the solution to Origin of the Universe...we don't even understand what we mean by origin.

Dr. Naralikar, are there other data points which also question the validity of the Big Bang Model?
