All species of particles are unified in superstring theory since each arises from a different vibrational pattern executed by the same underlying entity.
Some people think that the big bang is an explanation of how the universe began, its not. The big bang is a theory of how the universe evolved from a split second after whatever brought it into existence.
The boldness of asking deep questions may require unforeseen flexibility if we are to accept the answers.
Understanding requires insight. Insight must be anchored.
The real question is whether all your pondering and analyses will convince you that life is worth living. That's what it all comes down to.
Physicists describe the two properties of physical laws – that they do not depend on when or where you use them – as symmetries of nature. By this usage physicists mean that nature treats every moment in time and every location in space identically – symmetrically – by ensuring that the same fundamental laws are in operation. Much in the same manner that they affect art and music, such symmetries are deeply satisfying; they highlight an order and coherence in the workings of nature. The elegance of rich, complex, and diverse phenomena emerging from a simple set of universal laws is at least part of what physicists mean when they invoke the term "beautiful."
