Jayant Vishnu Narlikar Quotes

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.

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.

...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.

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.

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.

According to the big bang theory the universe is only 13 billion years old... 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 have not been able to relate the idea to the 'faster than light' neutrinos since there are no causality checks to decide if they are travelling in the past.

The Gran Sasso results could be seen as tentatively offering support for the big bang theory – if we could find a way to test that they are indeed travelling backwards in time.

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.

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.

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.

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.

During another examination the question paper read, ‘do any six questions, all questions carry equal marks’. But I attempted more than six questions and wrote for the examiner, “examine any six questions, all questions carry equal marks.

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.

Science popularization involves information about science explaining the things and their implications in detail, or any beliefs the reader might have and also tell them about the newer discoveries so as to enlarge the persons horizons.
