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 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.

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.

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.

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.

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.

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 Big Bang has to be right. Or equivalently, no faster-than-light neutrinos, no big bang.

There people who were leaders in their field in Cambridge and they lectured. And what impressed me the most was that all these big names never said that they were busy in their research and did not want to be burdened with lectures. They took their part in the lectures actively.

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.
