There is a belief in a creator who existed before the Big Bang and set the universe in motion, which is something that cannot be proved or disproved by science.

[I]t is surely a cultural deprivation to be unaware of the chain of events through which some mysterious genesis nearly 14 billion years ago triggered the emergence of atoms, galaxies, stars, and planets, and whereby, on at least one planet, Darwinian selection led to the emergence of creatures able to ponder their origins.

In 1956, when I began doing theoretical physics, the study of elementary particles was like a patchwork quilt. … The theory we now have is an integral work of art: the patchwork quilt has become a tapestry.

Any deviation from special relativity could point physicists toward an elusive goal, a quantum theory of gravity.

During the 1930s, Fritz Zwicky determined that clusters of galaxies have 10 times more mass than their light suggests, and termed the unseen mass “dark matter”.

We now believe that the universe is dominated by a completely unpredicted dark energy.

In 1917, [Einstein] introduced what he called the cosmological constant as a repulsive anti-gravity term into the field equation.

It is only slightly overstating the case to say that physics is the study of symmetry.
