Unified Theory Quotes (7 quotes)

Even if there is only one possible unified theory, it is just a set of rules and equations. What is it that breathes fire into the equations and makes a universe for them to describe? The usual approach of science of constructing a mathematical model cannot answer the questions of why there should be a universe for the model to describe. Why does the universe go to all the bother of existing?
A Brief History of Time (1998), 190.

I think the next [21st] century will be the century of complexity. We have already discovered the basic laws that govern matter and understand all the normal situations. We don’t know how the laws fit together, and what happens under extreme conditions. But I expect we will find a complete unified theory sometime this century. The is no limit to the complexity that we can build using those basic laws.
[Answer to question: Some say that while the twentieth century was the century of physics, we are now entering the century of biology. What do you think of this?]

If we do discover a complete unified theory, it should be in time understandable in broad principle by everyone, not just a few scientists. Then we shall all, philosophers, scientists and just ordinary people, be able to take part in the discussion of why it is that we and the universe exist. If we find the answer to that, it would be the ultimate triumph of human reason—for then we would know the mind of God.

In 2056, I think you’ll be able to buy T-shirts on which are printed equations describing the unified laws of our universe. All the laws we have discovered so far will be derivable from these equations.
Quoted in 'Brilliant Minds Forecast the Next 50 Years', New Scientist (18 Nov 2006).

Physics, as we know it, will be over in six months.
Max Born
As quoted in Stephen Hawking, Black Holes and Baby Universes and Other Essays (1993), 50. The context given with the quote was that in the late 1920s Max Born told made this remark to a group of scientists visiting Gottingen. This was shortly after the discovery by Paul Dirac, of the Dirac equation, which governs the behavior of the electron. (It seemed a comprehensive theory was imminent to unify the theories of physics.)

The ground of science was littered with the corpses of dead unified theories.
From Disturbing the Universe (1979), 62.

There may only be a small number of laws, which are self-consistent and which lead to complicated beings like ourselves. … And even if there is only one unique set of possible laws, it is only a set of equations. What is it that breathes fire into the equations and makes a universe for them to govern? Is the ultimate unified theory so compelling that it brings about its own existence?
Lecture (1987), 'The Origin of the Universe', collected in Black Holes And Baby Universes And Other Essays (1993), 99.

Carl Sagan Thumbnail In science it often happens that scientists say, 'You know that's a really good argument; my position is mistaken,' and then they would actually change their minds and you never hear that old view from them again. They really do it. It doesn't happen as often as it should, because scientists are human and change is sometimes painful. But it happens every day. I cannot recall the last time something like that happened in politics or religion. (1987) -- Carl Sagan
