A mind-bending discovery from the James Webb Space Telescope (JWST) is shaking up our understanding of the cosmos—suggesting that our universe may have been born inside a black hole.

Astronomers analyzing data from the JWST Advanced Extragalactic Survey (JADES) found something unexpected—ancient galaxies don’t rotate randomly. Out of 263 early galaxies, about 66% spin clockwise, while only 34% spin counterclockwise. In a universe with no preferred direction, we would expect an even 50-50 split. So why this strange imbalance? Scientists believe this could be a hidden fingerprint from the moment the universe was born—one that may link back to the spin of a black hole in a parent universe.

A Universe Inside a Black Hole? This discovery aligns with an idea called Schwarzschild cosmology, which suggests:

Our Universe is Inside a Black Hole: We exist within a black hole’s event horizon, a part of a larger "parent" universe.

Black Holes Birth Universes: According to Nikodem Poplawski’s torsion-based model, black holes don’t just collapse into singularities—instead, their spin and twisting spacetime create new universes.

The Big Bang Was a "Bounce": Matter collapsing into a black hole may have bounced back outward, causing the rapid expansion we see as the Big Bang. The spin of the parent black hole may have imprinted its rotation onto the galaxies in our universe—explaining the JWST’s observed spin bias.

Observations from both NASA’s James Webb and Hubble space telescopes created this colorful image of galaxy cluster MACS0416. The colors of different galaxies indicate distances, with bluer galaxies being closer and redder galaxies being more distant or dusty. Some galaxies appear as streaks due to gravitational lensing — a warping effect caused by large masses gravitationally bending the space that light travels through.

Like Taylor Swift, Our Universe Has Gone Through Many Different Eras

While Taylor's Eras Tour explores decades of music, our universe’s eras set the stage for life to exist today. By unraveling cosmic history, scientists can investigate how it happened, from the universe’s origin and evolution to its possible fate.

This infographic outlines the history of the universe.

0 SECONDS | In the beginning, the universe debuted extremely small, hot, and dense

Scientists aren’t sure what exactly existed at the very beginning of the universe, but they think there wasn’t any normal matter or physics. Things probably didn’t behave like we expect them to today.

Artist's interpretation of the beginning of the universe, with representations of the early cosmos and its expansion.

10^-32 SECONDS | The universe rapidly, fearless-ly inflated

When the universe debuted, it almost immediately became unstable. Space expanded faster than the speed of light during a very brief period known as inflation. Scientists are still exploring what drove this exponential expansion.

1 MICROSECOND | Inflation’s end started the story of us: we wouldn’t be here if inflation continued

When inflation ended, the universe continued to expand, but much slower. All the energy that previously drove the rapid expansion went into light and matter — normal stuff! Small subatomic particles — protons, neutrons, and electrons — now floated around, though the universe was too hot for them to combine and form atoms.

The particles gravitated together, especially in clumpy spots. The push and pull between gravity and the particles’ inability to stick together created oscillations, or sound waves.

Artist's interpretation of protons and neutrons colliding to form ionized deuterium — a hydrogen isotope with one proton and one neutron — and ionized helium — two protons and two neutrons.

THREE MINUTES | Protons and neutrons combined all too well

After about three minutes, the universe had expanded and cooled enough for protons and neutrons to stick together. This created the very first elements: hydrogen, helium, and very small amounts of lithium and beryllium.

But it was still too hot for electrons to combine with the protons and neutrons. These free electrons floated around in a hot foggy soup that scattered light and made the universe appear dark.

This animated artist’s concept begins by showing ionized atoms (red blobs), free electrons (green blobs), and photons of light (blue flashes). The ionized atoms scattered light until neutral atoms (shown as brown blobs) formed, clearing the way for light to travel farther through space.

380 THOUSAND YEARS | Neutral atoms formed and left a blank space for light

As the universe expanded and cooled further, electrons joined atoms and made them neutral. With the electron plasma out of the way, some light could travel much farther.

Frozen sound waves are visible as miniscule fluctuations in temperature, shown through blue (colder) and red (warmer) coloring.

As neutral atoms formed, the sound waves created by the push and pull between subatomic particles stopped. The waves froze, leaving ripples that were slightly denser than their surroundings. The excess matter attracted even more matter, both normal and “dark.” Dark matter has gravitational influence on its surroundings but is invisible and does not interact with light.

This animation illustrates the absorption of photons — light particles — by neutral hydrogen atoms.

ALSO 380 THOUSAND YEARS | The universe became dark — call it what you want, but scientists call this time period the Dark Ages 

Other than the cosmic microwave background, there wasn't much light during this era since stars hadn’t formed yet. And what light there was usually didn't make it very far since neutral hydrogen atoms are really good at absorbing light. This kicked off an era known as the cosmic dark ages.

This animation illustrates the beginning of star formation as gas begins to clump due to gravity. These protostars heat up as material compresses inside them and throw off material at high speeds, creating shockwaves shown here as expanding rings of light.

200 MILLION YEARS | Stars created daylight (that was still blocked by hydrogen atoms)

Over time, denser areas pulled in more and more matter, in some places becoming so heavy it triggered a collapse. When the matter fell inward, it became hot enough for nuclear fusion to start, marking the birth of the first stars!

400 MILLION YEARS | Dark matter acted like an invisible string tying galaxies together

As the universe expanded, the frozen sound waves created earlier — which now included stars, gas, dust, and more elements produced by stars — stretched and continued attracting more mass. Pulling material together eventually formed the first galaxies, galaxy clusters, and wide-scale, web-like structure. 

In this animation, ultraviolet light from stars ionizes hydrogen atoms by breaking off their electrons. Regions already ionized are blue and translucent, areas undergoing ionization are red and white, and regions of neutral gas are dark and opaque.

1 BILLION YEARS | Ultraviolet light from stars made the universe transparent for evermore

The first stars were massive and hot, meaning they burned their fuel supplies quickly and lived short lives. However, they gave off energetic ultraviolet light that helped break apart the neutral hydrogen around the stars and allowed light to travel farther.

SOMETIME AFTER 10 BILLION YEARS | Dark energy became dominant, accelerating cosmic expansion and creating a big question…?

By studying the universe’s expansion rate over time, scientists made the shocking discovery that it’s speeding up. They had thought eventually gravity should cause the matter to attract itself and slow down expansion. Some mysterious pressure, dubbed dark energy, seems to be accelerating cosmic expansion. About 10 billion years into the universe’s story, dark energy – whatever it may be – became dominant over matter.

13.8 BILLION YEARS | The universe as we know it today: 359,785,714,285.7 fortnights from the beginning

We owe our universe today to each of its unique stages. However, scientists still have many questions about these eras.

Our upcoming Nancy Grace Roman Space Telescope will look back in time to explore cosmic mysteries like dark energy and dark matter – two poorly understood aspects of the universe that govern its evolution and ultimate fate.

Just out of curiosity, is your Michael talking about anything specific? I only recognised Godel's Theorem (I think) being mentioned but I'm really intrigued by what he's talking about + the equations 👀👀

Everyone say thank you Michael for the theoretical physics lessons

A black hole is much more than just an empty void in space—it's a complex structure with distinct regions that define its behavior. Here's an excerpt showing some properties of this celestial body.

Here's a close-up for those who can't see (me)

" Jupiter the most badass planet in the Solar System... It is the largest & the oldest planet in the Solar System. It has 79 moons, some of which are even larger than planet Mercury! It is large enough to fit 1300 Earths. It is covered with giant storms some of which are even larger than Earth! jupiter is called a 'Failed Star If it had enough mass, its core could've sustained nuclear fusion like the Sun. And most importantly.. lts gravity protects Earth from asteroids & comets & also helps stabilize the Solar System"

The air is not a random bunch of gases simply drawn to earth by the earth's gravity, but an elixir generated by the soils, the oceans, and the numberless organisms that inhabit this world, each creature exchanging certain ingredients for others as it inhales and exhales, drinking the sunlight with our leaves or filtering the water with our gills, all of us contributing to the composition of this phantasmagoric brew, circulating it steadily between us and nourishing ourselves on its magic, generating ourselves from its substance. It is as endemic to the earth as the sandstone beneath my boots. Perhaps we should add the letter i to our planet's name, and call it "Eairth," in order to remind ourselves that the "air" is entirely a part of the earth, and the i, the I or self, is wholly immersed in that fluid element.
