“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.”

“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 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.”

“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.”
