“Scientists only understand 4% of universe”..i think they are exaggerating
Despite all the scientific breakthroughs and Nobel Prizes for discoveries, scientists seem to be no nearer to a possible answer to their main question – why did the universe appear?
RT sat down to talk to Aleksey Filippenko, an American astrophysicist and professor of astronomy at the University of California, Berkeley, CA.
He was the member of the team that received 2011 Nobel Prize for discovering the dark energy that is speeding up the expansion of the entire universe.
And he believes that it could have sprung into existence without any divine help whatsoever.
RT: You maintain you do not need any divine help to explain how the universe came to be. So, what is your version?
Aleksey Filippenko: Let me start by saying that I am going to discuss the universe only from the perspective of a scientist, from an intellectual perspective. I am not going to be talking about whether there is spiritual God or a personal God or a purpose to the universe – these are questions that scientists can’t address. My own belief is that once you have the laws of physics the universe just keeps going on its own. And it could even be that the laws of physics are all that you need in order to get the universe to start from the very beginning – the “Big Bang”.
RT: What is then the origin of the laws of physics?
AF: That’s a great question – what is the origin of the laws of physics? I don’t know. That’s a question science can’t answer. What if the laws of physics have always existed and they give rise to a universe – our universe – and perhaps even multiple universes. That is a possibility, but it is a possibility that is sort of outside the realm of science because we don’t know of any way to experimentally or observationally test whether that is a correct hypothesis.
RT: Let’s start from the very beginning – what gave rise to the universe, why was there a “Big Bang”?
AF: So, what gave rise to the universe is an interesting question. We don’t exactly know the answer to that. But we have some ideas: for example, if there was a pre-existing universe then what is called quantum fluctuation – little bits of energy coming into existence for a very short time and then usually disappearing – well, those can occasionally give rise to a universe because if a quantum fluctuation lasts for a long time it can grow to a very large size. And that can essentially give rise to a universe. And that universe might then have quantum fluctuations that produce other universes. So that would be a never-ending sequence of universes arising as a result of just fluctuations in energy in existing universes. That is one idea.
Or another possibility is that there is some sort of a hyperspace, some sort of a mathematical space in which the laws of physics existed and then the universes just sort of pop off like little soap bubbles that a child might blow. So there might be all these soap bubbles which are like different universes in a much bigger hyperspace within which the laws of physics operate for unknown reasons. You see, it all starts with the laws of physics, but I can’t tell you where they came from. What is very beautiful to me is that a very small number of laws can explain the vast complexity around us. With the one exception where we just still do not know – and that is life and intelligence. We just don’t know. Biologists have not advanced far enough to understand exactly how life arose and how intelligence arises. But the mechanical universes – amazingly complex, yet explainable with a few simple laws.
and what they do know is guesswork and theory..try about 1% not 4%..
