The big bang is the preeminent theory of modern cosmology. The model is strongly supported by evidence. But if the big bang caused the Universe, what caused the big bang? Everything from God to ...

READER QUESTION: My understanding is that nothing comes from nothing. For something to exist, there must be material or a component available, and for them to be available, there must be something ...

Sir Roger Penrose's Conformal Cyclic Cosmology hypothesis. Conformal Cyclic Cosmology is a story of the origin and the end of our universe from great mathematical physicist Sir Roger Penrose.

In Conformal Cyclic Cosmology the universe iterates through infinite cycles, with the future timelike infinity of each previous iteration being identified with the Big Bang singularity of the next.

Roger Penrose has shared in the Nobel Prize in Physics for his contribution with models of Black Holes. Penrose has used the renewed attention to push his 30-year old concept of Hawking Points and ...

Using a Socratic approach, we survey the best scientific ideas in physics regarding how a universe could arise from literally “nothing.” Key topics include: - The meaning of "nothing" in physics, ...

University of Oxford mathematical physicist Sir Roger Penrose won a Nobel Prize earlier this month for a lifetime of work studying black holes, singularities from which not even light can escape. Yet ...

Scientists have claimed that evidence for past universes may exist in the night sky – namely the remnants of black holes from another universe. The rest of this article is behind a paywall. Please ...

Thomas Smeenk, BA, unveils a proposed conformal invariant, A = E/(hv), explored as a potential bridge between General Relativity, Quantum Mechanics, cosmology, and string theory. "Physics has ...
