“The circumference of earth at equator is 40,000 km and by dividing it with 24 hours (earth completes its rotation in a day), it comes out to 1,667 km. This reverse phenomenon happened at 60 degrees latitude because their jet plane managed a speed of 833.5 km which is half of circumference of the earth.”

“Our test asked a focused question and the astrologers could not point toward any ambiguity in interpretation. We told the astrologers that the real predictive success could be claimed only at the 70% level for their sample size. The test demonstrated the hollowness of the basic claim of astrology.”

Astrology came with Alexander, says Jayant Narlikar

“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.”

“We all know that sun rises in the east and sets in the west, and earth spins on its axis from west to east. But on that day my jet plan was at 60 degree latitude near Greenland and the plane exceeded the speed of rotation of the earth on its axis so the sun was found moving from west towards east.”

His scientific explanation with regard to the position of sun closer to the west horizon, and the sun was going up, which he had noticed.
When Prof Jayant Narlikar saw the sun rise in the west

“So it was better to think of formulations which could explain the creation of matter without violating the law of conservation of matter…For that we used what is called as negative energy, which at that time was considered unrealistic. There was a good example of negative energy, mainly Newtonian gravity. Newtonian gravity is a negative energy system because gravitational potential energy is negative and we i. e, Fred Hoyle and me, worked out a fairly consistent method of describing this whole thing. Today what people call phantom fields, an idea which is catching up with people trying to explain some problems of the big-bang, these phantom fields are what we had proposed way back in the 1960’s.”

“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.”

“In the Cambridge mathematical tripods, they said, ’do six questions. Complete questions carry proportionately more marks than an equal number of fragments. Till you attempt half of the questions you won’t get full credit’. Upon declaration of result I found that I had scored 110 out of hundred in one paper, 140 in another and likewise in all the rest. I was confused. So my tutor explained to me that although they write ‘do six questions’, you can attempt as many as you want. They award you marks for whatever questions you answer correctly and the ranks are on basis of the score.”

“Each scientific institute in my opinion should have a public outreach program…all the research you are doing is funded by the government. The government gets MONEY from the people, so you owe something to the people. You are shutting yourself in an ivory tower, saying that all these people outside the scientific community do not understand it. That is not the right attitude.”

Jayant Narlikar's Cosmology

“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.”

“Biologists conventionally think that it is a crazy idea. First they argued that micro organisms cannot last through the passage through UV, X rays, gamma rays. Now people have shown in laboratory experiments that bacteria learn to survive. So that argument doesn’t work. People are still not receptive. It is like the heliocentric theory of Copernicus. Biologists are going through the same phase.”

“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.”

Jayant Narlikar's Cosmology

“…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.”

Jayant Narlikar's Cosmology

“In our theory we have multiple “mini bangs” and these mini bangs are not mysterious like the big bang but they come because of the concentration of what we call negative energy fields. Whenever there are pockets of negative energy, they explode and produce a mini bang. We believe there’s a mini bang producing energy in the centre of quasars, which are very bright star like objects. Gamma ray bursts, which are the explosive creations of gamma rays, are another example of a mini bang. These are actually happening. These can be described by normal physics, but the big bang cannot. The big bang theory does not use any mathematical formulation so they can’t say why the bang occurred.”

“If you see firm evidence of neutrinos arriving at the detector before they are sent, that can't happen in a Steady steady state cosmology, so the [[w:Big Bang|big bang has to be right. Or equivalently, no faster-than-light neutrinos, no big bang.”

“Now with the big bang there is only one event that happened. So like the sun you can’t say that there are other big bangs going on that are what ours was like. The second problem is that at the big bang mathematics and physics break down. So there is no way of mathematically describing it. That is not a satisfactorily scientific approach, to ascribe something to speculations which you cannot justify using mathematics and physics.”

Jayant Narlikar's Cosmology

“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.”

“Fred Hoyle and Wickramasinghe have argued that microorganims fill up the whole of space. One finds dust and biological molecules between stars. Why not microorganisms? They assumed in one example, E. coli filling up interstellar space and then they calculated how much the absorption of light at different wavelengths from the E. coli model would be. They showed that the extinction curve i. e. absorption curve, was precisely followed for some infra red source. So their argument was that these micro organisms must exist.”
