Lots of physicists were discouraged about the news of evident discovery of the gravitational waves was expected to be a fallacy. Though, on the other hand, Neil Turok, a cosmologist from the Perimeter Institute for Theoretical Physics in Waterloo, Ontario believed a bit justified.
However, he has been making a bet that primeval gravitational waves would never be seen. Turok said that, I am very surprised to hear the new results from the Planck satellite examining light from the big bang show that, believed surveillance of gravitational waves from the South Pole’s BICEP2 experiment in March was most likely tainted by a mist of dust in the galaxy.
What does the Planck’s latest analysis all about?
According to the Planck paper, the entire BICEP2 signal is just because of the dust. This seems to be immense news. In order to differentiate the dust and the BICEP2 signal, we need to look deeply in numerous frequencies. Actually, this is the basic problem with the BICEP2 argument, as they were just using one frequency. Presently, Planck seems to be the only experiment with the potential to look in several frequencies. They found the expected contribution from the dust more than accounts for the BICEP2 calculated signal.
What does inflation means, which actually predicted the gravitational waves?
In fact, the theory of inflation has conquered cosmology for nearly 30 years. I am one of those people who actually pointed out its problems and limitations.
I have been making the cyclic picture of Universe having big bang just is the latest in an endless number of cycles going back into the past. The cyclic picture shows that there will be big bangs in the upcoming era. Paul Steinhardt helped me to develop this theory.
The theory of inflation stated that the cyclic model portrays zero gravitational waves. If the gravitational waves are seen, then all the models I have developed so far will be disapproved. I will also be happy, if they all got disapproved. I don’t believe that’s the final answer. I also believe that the cyclic models are quite complicated.
How did you end up making a bet over gravitational waves?
Stephen Hawking think that the simplest inflation models, the most conceivable ones, will make adequate gravitational waves which are detectable. Back in 2001, I made a bet with Stephen that these gravitational waves would not be present. When the BICEP2 consequence leaked, Stephen talked to BBC that he won the bet with me. However, my reaction was simply, I need verification. Though in the World of Science, we never rely on the results of one experiment, it needs to be re-checked. Therefore, my results indicated that there are various problems with the BICEP2 experiment.
Do you think you are going to win?
I am near to winning my bet. The previous Planck results indicated the level of gravitational waves is less than ½ of what the BICEP2 is arguing. According to the recent result of Planck mainly make that very solid. All I have to do is to go with another factor of two down and that’s it. I won my bet with Stephen. I am hopeful that it would ultimately occur in Nov as BICEP2 and Planck are working together. BICEP2 just believes that when they unite with Planck they will amazingly identify facts of gravitational waves together. It may happen, they could be lucky, but in my view that’s wishful thinking.
Is all this about BICEP2 is damaging the fields, or is just the way science said?
I thinks lot of people stay silent about this and agree that people are really very excited about the results, there are too many claims related to this, so that’s why we really need to be very much careful and should consider all the facts which are scientifically approved. And researchers should have said that, they have found very interesting facts about this which they will prove it after some of the experiments in near future, and May be it could be dust particle or something else. Actually I expect them to say this after hearing rumors; I called them up before press conference and also advised them to be much more cautious. Unfortunately they didn’t listen to me, and now wishing they had.
This is very common for science, that universe set us at right place; all this is just explanations we give to our self that we are taking measurements and universe is giving us clues about what happened at the big bang. All this was called philosophy before but now it’s called a real science.
If there are no primitive gravitational waves, what does it mean?
Analyzing that big bang is hidden by dust is unenthusiastic. But our observations up till now are giving simple and clear picture of universe. But in this regards our theories are getting more and more complicating. I found it very exciting that our theories are just confusing us about the real fact but for the very first time the real clues are present which we are unable to see.
