🌌🔄 The Big Ring and the Echo from a Previous Eon: Has Alexia Lopez Found Evidence for Penrose’s Conformal Cyclic Cosmology?

Dear explorers,

When we concluded the previous leg of our epic voyage across the Dirac Sea, we left our sails open for a new horizon. And now the cosmos sends us a sign – magnificent, mysterious, and powerful enough to shake the very pillars of modern cosmology.

In 2024, doctoral student Alexia Lopez (University of Central Lancashire) discovered a structure that should not exist. The Big Ring – an enormous ring of galaxy clusters – spans 1.3 billion light-years in diameter and lies an astonishing 9.2 billion light-years away. And it is not a lone giant. Just two years earlier, the same researcher had identified the Giant Arc – another colossal formation, stretching 3.3 billion light-years across. Both the Arc and the Ring are located in the same cosmological neighborhood, only 12 degrees apart on the sky.

These structures are not just big. They are impossibly big.

🌍 The Triumph and Crisis of the Cosmological Principle

Ever since Einstein and the first relativistic models of the cosmos, physics has rested on the Cosmological Principle: on sufficiently large scales (hundreds of millions of light-years), matter is homogeneously and isotropically distributed. Seen from afar, the universe should resemble the calm, foamy surface of the Dirac Sea – without enormous, individual waves.

The standard ΛCDM model (describing a universe made of dark energy Λ and cold dark matter CDM) predicts that the largest structures cannot exceed about 1.2 billion light-years. Simply put, not enough time has passed since the Big Bang for anything larger to form. Yet the Big Ring and the Giant Arc are right there, at a distance of 9.2 billion light-years – when the Universe was significantly younger than it is today.

This discovery presents the Cosmological Principle with the gravest crisis in its history.

🌀 Penrose and the Echo from a Previous World

And here, as we have grown accustomed, Roger Penrose takes the stage. His Conformal Cyclic Cosmology (CCC) offers an explanation that is both radical and elegant: our Big Bang is not the beginning of everything, but merely a transition from a previous eon. In this model, each eon begins with a Big Bang and ends in infinite dilution, with the conformal future of one eon smoothly continuing into the conformally stretched beginning of the next.

Penrose has long argued that remnants of previous eons should be visible in the cosmic microwave background (CMB) , in the form of concentric circles he called Hawking points – the final cries of supermassive black holes that evaporated at the end of the old eon.

However, the Big Ring and the Giant Arc are not circles in the CMB; they are vast formations of galaxies. Alexia Lopez herself has stated that CCC could be a possible explanation for their existence. How?

Penrose’s latest papers with Meissner (2025) introduce the concept of a Gravitational Wave Epoch (GWE) immediately after the transition between eons. These gravitational waves, born from the collisions and mergers of black holes at the end of the old eon, could leave imprints on the matter distribution of the new eon. The Big Ring could be a direct fingerprint from a previous universe – a structure that did not form within our own cosmos, but was “inscribed” into it by the wind blowing through the eons.

In this picture, the Big Ring and the Giant Arc are not anomalies. They are fossil records – materialized waves preserved from the previous eon. Their size is not a paradox, because they did not need to form in the time since our Big Bang. They have been there since the very beginning of this universe, a memory of a world that was.

📐 Dirac and the Changing Fabric of the Cosmos

The alternative interpretation, which you have already intuited, brings us back to our captain – Paul Dirac. His Large Numbers Hypothesis (1937) suggests that fundamental constants – the gravitational constant $G$G, the fine-structure constant $\alpha$α, even the ratio of electromagnetic to gravitational force – are not truly constant, but evolve with the age of the universe.

If, in the first few billion years after the Big Bang, these constants differed from today’s, structure formation could have followed entirely different rules. In the early universe, where gravity may have been a little stronger or a little weaker, structures that now appear impossible could have emerged. The Big Ring would then be not an “echo”, but a memory of a time when the very rules of the game were different.

This thread also weaves directly into the mystery of dark energy – that same 120-orders-of-magnitude catastrophe we have written about. If the constants evolve, dark energy itself is not constant; it is the changing breath of the sea, something that lives and breathes with the universe.

🌊 A Wave on the Surface of the Dirac Sea

We can now weave all the threads together into a single picture:

• The Dirac Sea – an infinite ocean of quantum fields, with its internal SU(3) × SU(2) × U(1) currents – exists not only in space, but also in time. It stretches across the eons.
• The gravitational wind, which we described as an external influence on the sea, does not blow only within a single eon. It carries across the inter-eon transitions, just as Penrose suggests. The Big Ring is a fossilized wave – a trace of the wind from the previous eon that survived the reset of the Big Bang.
• The whisper of conformal geometry has turned into immense rings of galaxies – foam on the surface of the sea that has become visible only now, when our telescopes are powerful enough to register it.
• Dirac’s varying constants become a natural part of this ocean: the sea is not static, its “density” and “temperature” change as the universe ages, altering the way waves arise and propagate.

🔮 Open Horizons

These discoveries do not close the story – they open it. The questions are now more dramatic than ever:

• Will future missions, like the successors to Hubble and the James Webb Space Telescope, find even more such structures, confirming that the Cosmological Principle is dead?
• Are there, in the CMB, subtle correlations with the Big Ring that could link these structures to Hawking points?
• How can we experimentally test Dirac’s hypothesis of varying constants, when the changes are extremely slow and require cosmological scales?
• And most importantly: if Penrose is right, what else has survived from the previous eon? How much of our universe is truly “ours”?

Our voyage across the Dirac Sea continues. The Big Ring is a lighthouse on the horizon – a reminder that the sea is infinite, deep, and filled with secrets waiting to be read. Every new wave is an invitation to dive deeper.

And the gravitational wind, it seems, blows stronger than ever.
