Roger Penrose

Consciousness is the phenomenon whereby the universe's very existence is made known.

There is something absolute about the 'now' in our conscious experience, but physics seems to have no place for it.

One's consciousness is not a thing that can be computed; it is a thing that can be experienced.

The laws of physics produce complex consequences, but they do not produce intentions.

I think I can safely say that nobody understands quantum mechanics.

The trouble with string theory is that it's not really a theory. It's a collection of ideas, hopes, and aspirations.

The universe is not just 'out there'; it is also 'in here'.

Time is something that prevents everything from happening at once.

The Big Bang was not the beginning. It was the beginning of our universe as we know it.

The mind is not a computer. It is a quantum system.

Mathematics is not a game. It is a way of understanding the world.

The universe is not random. It is governed by laws that are beautiful and elegant.

The world is not made of particles, but of fields.

Gravity is not a force. It is the curvature of spacetime.

The second law of thermodynamics is the only law of physics that distinguishes between past and future.

A theory that does not explain consciousness is not a complete theory of the universe.

The universe is not a machine. It is a living, breathing thing.

The human brain is the most complex object in the known universe.

The laws of physics are not arbitrary. They are necessary for the existence of life.

The universe is not just a collection of objects. It is a web of relationships.
