Quantum theory as a whole is wrong, and the role of gravity in quantum mechanics conflicts with the principle of superposition.

I don't believe in inflation, which is the idea that our universe evolved from a previous universe, forming an ever-repeating cycle.

I offer ambitious frameworks like twistor theory that could potentially unify quantum theory with general relativity.

Twistor theory, which I started in 1963, has had many developments and has spread interest in different areas of physics.

The positive-negative frequency idea in twistor theory was something I learned from Engelbert Schuching, emphasizing the importance of splitting field amplitudes in quantum field theory.

Maxwell's equations are conformally invariant, meaning they depend on the space-time structure independent of scaling.

The splitting of positive and negative frequency components in quantum field theory is not conformally invariant, which presents a conceptual impasse.

I realized that the Robinson Congruence of rays, which describes light rays, has six degrees of freedom, while light rays themselves have only five degrees of freedom.

Twistor theory originated from my realization that light rays can be represented by points on a five-dimensional boundary, allowing for a global description of space-time.

Twistors are inherently chiral, meaning they have a built-in chirality that reflects the nature of particles like photons.

I see the restriction of my theory to four dimensions as a strength, as it ties directly to the physical world rather than abstract mathematics.

Twistor theory can be applied in complex space-time, particularly useful for quantum theory involving wave functions.

In quantum mechanics, the wave function is typically linear, allowing for the superposition of states, but in my approach, I consider a non-linear graviton wave function.

The concept of twistors introduces a new kind of curved twistor, which is essential for understanding complex solutions in physics, but it also leads to inherent confusion in the theory.

The collapse of the wave function is a physical process, and I argue that quantum mechanics, as it currently stands, is incomplete and needs significant modification.

I believe that consciousness does not collapse the wave function; rather, the collapse of the wave function may produce consciousness.

The principle of equivalence in general relativity conflicts with the principle of superposition in quantum mechanics, highlighting a fundamental tension between these two theories.

I propose that gravity plays a role in collapsing the wave function, suggesting that the energy cost of creating a superposition can lead to a collapse in a very short time.

I think the retrocausal idea suggests that quantum reality can propagate backwards in time, affecting measurements before they happen.

In quantum mechanics, you can ascertain the state of a system, but you cannot confirm it in the same way you can with classical systems.

Einstein believed that if a measurement can be made without disturbing a system and gives a 100% certainty answer, then that measurement reveals an element of reality.

The spin of a spin-half particle can be measured, but you cannot ascertain its state without performing a measurement.

Free will might be the ability to make decisions based on your understanding, even if those decisions are ultimately determined.

I believe consciousness is fundamental, but it depends on the framework within which you're asking the question.

I think the conformal cyclic cosmology (CCC) theory changes our understanding of cosmology significantly, addressing the specialness of the Big Bang.

When advising students, I suggest they pursue what excites them while also keeping an eye on broader developments in the field.
