Is the universe gently twirling? Scientists say the universe could be completing one rotation in nearly 500 billion years

The universe is a place of mind-bending mysteries and vast, ancient expanse that is still not fully understood. Our cosmos never ceases to surprise us, be it the Big Bang, black holes, dark matter, or the accelerating expansion of space. There have been decades of research and advanced technologies like the James Webb Space Telescope, which have been constantly researching this, but still, the astronomers have some fundamental questions about the universe's structure and behaviour remaining in their bag.
Now, a new study from the
University of Hawai'i Institute for Astronomy
has probably brought us one step closer to resolving some unknown mysteries about the universe.
A Universe that spins?
In a study published in the Monthly Notices of the Royal Astronomical Society, astrophysicist István Szapudi and his team suggest that the universe could be slowly rotating, completing one full revolution roughly every
500 billion years
. That is very slow and too subtle for current instruments to directly detect, but it could be enough to change the way space behaves on a cosmic scale.
The idea comes from a simple observation that everything in the universe spins. Planets, stars, galaxies, and even black holes all rotate.
So why not the universe itself?
'To paraphrase the Greek philosopher Heraclitus of Ephesus, who famously said, 'Panta Rhei', which means that everything moves, we thought that perhaps Panta Kykloutai – everything turns,' said Szapudi, lead author of the study, as quoted by the University of Hawai'i news release.
What is the Hubble Tension?
The Hubble tension is a long-standing difference between two different ways of measuring the universe's expansion rate. One method is through using nearby supernovae and galaxies, which gives a higher value than another method that looks at cosmic microwave background radiation from the early universe. These conflicting numbers have confused scientists and led some to suggest that entirely new physics may be needed.
But Szapudi's team created a mathematical model that includes a small amount of cosmic rotation, without breaking any known laws of physics. 'Much to our surprise, we found that our model with rotation resolves the paradox without contradicting current astronomical measurements,' Szapudi said.
What is practical about the model?
What makes this model particularly suitable is that it doesn't require new theories or particles. It fits within standard physics by also offering a novel explanation for a decades-old cosmic puzzle.
"It is compatible with other models that assume rotation. Therefore, perhaps, everything really does turn. Or, Panta Kykloutai!' Szapudi added.
If this rotating universe theory holds up under further studies, it could be quite a progress in how we understand the cosmos.

Our universe might have an expiry date and it's sooner than we thought

What the new model proposes Live Events Big Crunch: The opposite of the Big Bang The evidence behind the claim Still just a theory, for now (You can now subscribe to our (You can now subscribe to our Economic Times WhatsApp channel The universe may not be heading for an eternal stretch into emptiness, as once assumed. According to new findings from two of the largest astronomical surveys — the Dark Energy Survey (DES) and the Dark Energy Spectroscopic Instrument (DESI) — the mysterious force known as dark energy could be shift, if real, has serious consequences. Instead of expanding forever, the universe might one day contract. Scientists now believe a complete reversal could start within 10 billion years, ending in a collapse known as the Big Crunch These conclusions come from a new theoretical study, currently in preprint and awaiting peer review, that presents a bold reinterpretation of how cosmic forces years, physicists assumed dark energy was steady and uniform, based on a simple number called the cosmological constant in Einstein's general relativity. But the latest analysis challenges that study, reported by introduces two components behind dark energy: the cosmological constant and a particle known as the axion. Axions are hypothetical ultralight particles that rarely interact with matter. Yet, they could fill the universe and account for much of its current accelerated cosmological constant, by contrast, is a fixed energy value in empty space. But in this model, it's not positive. It's team behind the research explained their reasoning clearly. 'We are living in a temporary period of accelerated expansion,' they wrote. 'It is heavily driven by the axion field.'Right now, axions are doing most of the work in keeping the universe expanding. But over time, these particles are expected to lose their influence. Once they fade, the negative cosmological constant will begin to dominate. This shift would decelerate the universe's expansion could not only stop but happens next? According to the model, gravity would begin to pull everything back in. Galaxies would start to draw closer, merge, and collapse into each other. Temperatures would rise. Space would grow smaller, hotter, and the final act, all matter and energy would compress into a single point — a collapse, termed the Big Crunch, is effectively the reverse of the Big Bang The study predicts the beginning of this reversal could occur in 10 billion years. The contraction would then take another 10 billion years to complete. The full lifespan of the universe, under this model, would be about 33.3 billion already 13.8 billion years into that DES and DESI surveys have mapped millions of galaxies to measure how the universe expands over time. These surveys are central to modern cosmology, offering one of the most detailed views of the universe's large-scale recently, all observations supported the idea that dark energy was constant. But the new data show signs that it might be insight gave rise to the axion-dark energy model, or aDE, a theoretical framework that incorporates both axions and a changing cosmological explained by 'One of the most striking findings in the new study is the possibility that the cosmological constant — which reflects the energy density of space itself — may be negative.'The study's authors are careful not to overstate their findings. The model, while compelling, is still under review and not confirmed.'These are preliminary findings,' the researchers acknowledged. They stress that deeper space surveys and next-generation telescopes will be crucial for testing whether dark energy really does evolve with the idea is already sparking serious debate among physicists. If it holds, it would force scientists to rethink the universe's timeline — and its theories go further. They suggest the Big Crunch might not be the absolute that final singularity could trigger another Big Bang. A fresh cycle. A new universe. Though these ideas remain speculative, they reflect just how much we still don't understand about the nature of now, the only certainty is that the universe might be less predictable than once believed. As astronomers dig deeper into the skies, the answers we get may continue to surprise us.

The Mathematics Of The Gita

The Gita is an intriguing work; there is much more hidden in its short review of the entire gamut of Indian darshana than is visible on a surface view The Gita is a literary masterpiece. When I say literary, I am not including its remarkable exposition of the various Indian darshanas and their integration into a coherent vision, or its rhetoric, or the spiritual stepwise evolution experienced by the seeker who dives into it and adheres to it from beginning to end. I bring to your attention an aspect of the Gita that is often ignored. Its symphonic structure conceived in 700 shlokas is an expression of what Sri Aurobindo called complex harmonies. Its structure of independent shlokas that are strung together through the various means of rhythm, internal referencing, refrains, and a didactic and dialogic process that builds up chapter by chapter creates a kaleidoscopic experience that is fluid, alive, and constantly fresh. My soon-to-be-released book The Literary Genius of the Gita explores this aspect of the scripture. But there is another more esoteric and hidden aspect that might be worth exploring. That is its mathematical structure of matrix-like configurations that too has hitherto been ignored. The present essay is an attempt to explore this characteristic of its poetry. It may be worth mentioning here that the tradition of Sanskrit poetry, as shown by Pingala in Chhanda Shastra, is unique that its letters or varnas can be arranged in a binomial pattern. That is, the short syllables are assigned a value of 1 and the longer syllables a value of 2. When the varnas are represented by their mathematical value, we see interesting patterns emerge that were described by him in detail as an aspect of Sanskrit prosody. The only other language that assigns a mathematical structure to its phonemes that I know of is Hebrew especially in the Kabbalistic traditions. Modern mathematical structures such as Pascal's triangle and Fibonacci numbers were described by Pingala in his Meru Prastara couple of millennia ago. How far can we explore this today with artificial intelligence? Recently a write-up was published by Thomas Kissel in the journal Greek Reporter with the title 'Greek Philosopher Plato's Secret Code Discovered and Solved, Historian Claims'. It claims that there is a code of musical pattern buried in Plato's writings, most notably The Republic, discovered by a historian, Dr Jay Kennedy. The code seems to portray the entire Greek musical scale that contains twelve notes. We too have studied the patterns in the Gita from an Indic perspective with the help of our custom-designed AI software. These are the findings we came up with that may be of interest: We know that the Gita is divided into 18 chapters containing a total of 700 shlokas. Triadic structures are frequently seen such as three gunas (sattva, rajas and tamas). Sri Krishna classifies a tri-fold structure of many of his essential concepts, such as the triune path of Jnana-Karma and Bhakti, and the three types of knowledge, three kinds of action, three types of understanding and even three types of happiness in the 18th chapter, and these elements correspond to the three gunas that underline the play of Prakriti, or the principle of manifestation in Sankhya Yoga. Number 9 is often employed metaphorically. For example, the body is described as the 'city of nine gates' in chapter 5. Other symbolic use of numbers such as 1000 appear in chapter 11 to describe the dazzling manifestation of Sri Krishna's Vishvaroopa. There may be more as our AI system tells us: 'Some intriguing patterns emerge when looking at the proportions and sequence of verses in the Gita." 'Golden Ratio in Structure: It has been observed that the most climactic chapter – Chapter 11, where Arjuna witnesses Krishna's universal cosmic form (viśvarūpa) – occurs about 61 per cent of the way through the 18-chapter text. Chapter 11/18 is approximately 0.611 of the way in, which is remarkably close to the golden ratio (≈0.618). By verse count, too, the revelation of the cosmic form falls in the general vicinity of the 432nd verse out of 700 (around 61.7 per cent) — not exact, but notably close. This could be coincidental, but it does mirror a common storytelling technique of placing a dramatic 'golden climax" about two-thirds through a work. The fact that viśvarūpa darśana is the Gita's emotional and philosophical high point lends credence to the idea that the text intentionally peaks around the golden-section division. In other words, the narrative pacing aligns with an aesthetically pleasing ratio. (Whether Vyāsa consciously used the golden ratio is speculative; however, Indian tradition did employ harmonious proportions in art and architecture. The ancient Vedic science of design, Vāstu Śāstra, extensively uses the golden ratio in temple architecture, so the concept of an ideal division would not be foreign to the culture." There may be more such as instances of the use of Vedic and Pingala's numerology in the Gita, such as the use of Fibonacci numbers, Golden ratio in verse ratios, conscious numerology, etc. The Gita also uses musical and cosmic symbols. When we ran the AI application on the verses of the Gita, its conclusions seemed to support the hypothesis I have presented in my upcoming book, in pointing out the basic 'musical and mathematical resonance in language: it is worth noting that the Bhagavad Gita is mostly composed in anuṣṭubh meter, a quantitative verse form of 32 syllables (in two halves of 16 syllables each). This even, steady meter lends a rhythmic and almost mathematical cadence to the entire text. Each śloka can be seen as a couplet of two 16-syllable lines, giving the discourse a structured flow. This consistency is analogous to a piece of music maintaining a time signature – it imposes an underlying order on the content. The Gita occasionally uses other meters for special verses (some verses in Chapter 11 use triṣṭubh meter, 44 syllables, to convey the grandeur of the scene), but by and large the metrical discipline is maintained. The uniform meter might not be a 'code," but it is a designed pattern that aids memorization and recitation, reflecting the oral mathematicality of Sanskrit prosody" There is more. Mantric repetitions, alliteration, sound patterns, puns and double meanings, structured lists, recurring phrases or formulae, etc. It was impressive to have our AI application decode another aspect of The Literary Genius of the Gita. It concludes, 'In essence, the Gita's linguistic fabric is highly patterned, but these patterns serve didactic and emphasis purposes more than hiding secret messages. The 'code' of the Gita's language is in its mantra-like quality — through repetition, parallelism, and enumeration, it imprints ideas on the mind. For example, by the end, the reader has heard dharma dozens of times, yoga in many compounds, the refrain of 'surrender' in various forms — a bit like a musical theme recurring in different keys. This can be likened to a computational algorithm where key variables (dharma, atman, yoga, bhakti, etc) are revisited in multiple contexts, steadily building a complete picture. Notably, when comparing to the idea of a 'Plato code' (where a hidden musical-temporal structure was proposed in Plato's texts), the Gita's approach to encoding wisdom is more overtly structured rather than cryptographically hidden. It uses the natural Sanskrit propensity for symmetry and repetition as its 'code', making the text rhythmic, memorable, and conceptually clear." Indeed, the Gita is an intriguing work. There is much more hidden in its short review of the entire gamut of Indian darshana than is visible on a surface view. It is my hope that we uncover this multi-dimensionality and let it reveal the cryptic, the occult and esoteric aspects of its message. It is a 'highly ordered work', as our AI says, but there is a lot of method in its inspiration. Perhaps that is the great and open secret that invites us repeatedly to its mystery and genius.

The Unlikely Space Rangers

While most 14-year-olds were navigating adolescence through video games and schoolwork, Snehadeep Kumar was already charting a course for the stars. Today, at just 21, he and his business partner Mohit Kumar Nayak are developing shoebox-sized CubeSats in their lab in Bhubaneswar—marking India's first student-led initiative to detect gamma rays from space. 'Our research shows we can reduce the cost of billion-dollar satellites by about 98 per cent at an almost similar accuracy,' says Snehadeep, who is also the youngest Indian in history to be elected a fellow of the Royal Astronomical Society. Their findings, presented at the prestigious International Astronautical Congress, have piqued the interest of ISRO. Snehadeep's fascination with space began early—inspired by Discovery Channel documentaries and a science encyclopedia that was given to him as a gift. Yet, it wasn't a telescope or lab experiment that shifted his path but a humble school science project involving drumstick (moringa) seeds in Class 9. 'I was working on a project involving the use of drumstick seeds for water purification,' he recalls. 'I showed it at an exhibition hosted by SRM University in Kolkata and then at another exhibition. One of the teachers there suggested that I publish such research works.'
