“in our society at all levels not only uneducated but educated as well are dominated by superstitions of various kinds. The superstitions of the educated are only more sophisticated than those of the uneducated. So one needs to introduce real knowledge in place of superstitious beliefs. You need to explain to people believing in superstitious ideas that the ideas are not correct and this can be verified experimentally. When doing science popularization you have to express some facts of the real universe or the real world to the person who is not willing to believe in it and if you express it in a very pedantic way or say to the person that you are a fool, you should not believe this then it is not good because then he will believe in his superstitions even more. So you have to persuade him to think for himself, you don’t tell him what to believe but you ask him to try this experiment and see what is the reality. So that way you may be able to convince the person.”

“Found that in a universe that is expanding after a big bang event, neutrinos would turn up at a detector before they were emitted. Only future-going neutrinos were possible in the Steady state cosmology while the ever-expanding big bang models gave neutrinos travelling into Steady State theory to the past.”

“When you claim that the universe started in this particular way you are making a very profound statement. If I make a statement saying that the sun started in a certain way, I would immediately be asked for proof that the sun started in that way. I will have to go around gathering evidence of w:Solar systems}Solar systems forming, stars forming. I will have to produce evidence saying that this is how new solar systems are being formed, so the sun must have been formed in the same manner. That is a reasonably credible assumption.”

“Since the universe is infinitely old, you should see some very old stars. According to the big bang theory the universe is only 13 billion years old. No stars should be older than 13 billion years. In our cosmology, stars older than this should exist. So we are on the lookout for very old stars. We made some observations [a year ago] which we are still trying to explain but the simplest explanation seems to be that there stars that are 20 billion years old.”

“I went to Cambridge to do higher mathematics, that was my first goal and appearing in the university exams in mathematics. You are given a menu of various branches of mathematics, pure as well as applied. So I found that applied aspects, especially application to astronomy were very interesting. And the speakers on both courses, that is the lecturers were also very good. At that time, I also read a book by Fred Hoyle called ‘Frontiers of Astronomy’, which gave a very readable account for a layman for what was happening in astronomy. So, all these factors made me go into the research field of astronomy. Because one is required to choose which branch of mathematics one takes as research field. In Cambridge, astronomy is treated as a branch of mathematics. So I choose that.”

“In western society, there is a problem similar to India that the income of a research scientist is less than that of a management person. But perhaps the facilities and the infrastructure being much advanced in the western universities, they are able to attract and retain the people. In our case this can happen but not to the extent we would like. A corrective measure to some extent has been taken by the establishment of the Indian Institutes of Science Education and Research (IISERs). They are doing for pure sciences what IIT’s do for applied sciences. Since they are attracting good talent it may happen that you will have more input in research in the next ten years.”

“…mention is made of evidences in favour of the big bang, like the microwave background. It is a relic radiation supposed to have formed very early after the big bang. As the universe expanded it cooled down and its present temperature is at 2.7 K. The only fact which is measurable or has been measured is that there is a background of 2.7 K temperature. Saying that this is left over from the early universe is a speculation. It is a part of a theoretical structure I am supposed to have built which enables me to say that it is a relic of that early-on era. We have given a different explanation. Helium forms by fusion of hydrogen inside a star like the sun, leading to radiation. One can ask the following question: if all the helium that you find in the universe was formed in stars sometime or the other, how much radiation will be formed and what would its temperature be? The answer is 2.7 K. If you ask a big bang person why his relic radiation today has a temperature of 2.7 K he doesn’t know. This alternative explanation that I’m giving is able to do more than what the big bang does. So I don’t see any reason to say we have a very positive proof of the big bang happening.”

“In 1963, when I completed my PhD, it was mostly on the steady-state theory using mathematical formulations to describe creation of matter. People always argued that you cannot have matter coming out of nothing, what would happen to the law of conservation of matter. It is a normal criticism of the steady-state theory. One could answer it either in one sentence by saying what is the big-bang theory where the entire universe came out of nothing, so you are violating the law of conservation of matter and energy in a big way. But that would be to point out the weakness of the other theories and not answering your own theory.”

“Space-time in an expanding universe changes over time, so the full quantum description of a neutrino. in that type of universe is different in the past and the future. Neutrinos would behave in both expanding and unchanging "steady state" universes.”

“The study he conducted with Dabholkar goes to explain why astrology is not a science through a simple experiment. They adopted an experiment conducted by Bernie Silverman, a graduate student of Michigan State University, USA. They collected horoscopes of 100 scholarly students and 100 students with learning difficulties.”

“Guru: Today I will discourse upon the violence in astronomy.
Disciple: Revered Sir! Will you be describing the violent phenomenon in the Universe?
Guru: Yes, and I will also dwell upon the controversies amongst the astronomers about what these events imply – controversies which are no less violent than the phenomena themselves

The one aspect of the star-studded night sky which impresses the casual observer most is its tranquility. The peace and quiet of the heavens with the marked contrast to the hurly burly of life on the earth have inspired poets, philosophers, and religious thinkers from time immemorial. Even the amateur astronomer viewing the night sky from his proverbial roof top telescope sees a picture which changes very slowly from night to night. The occasional visit of comet, the fall of a meteorite, or in these modern times the passing of a man made satellite are examples of events which introduce transitory variation on an apparently steady cosmic theme.”

“He is a cosmologist of international repute and best known for his work on the conformal gravity theory, together with his mentor Fred Hoyle. He also set up the Inter-University Centre for Astronomy and Astrophysics (IUCAA) in Pune. More recently, he was involved in an effort to sample air from the atmosphere at heights of 41km for microorganisms. This study reported at least two strains of bacteria and one fungus that were cultured in the lab. If these findings hold up to further enquiry, they provide a new perspective on life on earth and its beginnings.”
