🚨 The James Webb Telescope has spotted oxygen just 300 million years after the Big Bang—a discovery that defies everything we thought we knew about the early universe. ⚛️✨

Astronomers are once again being forced to rethink the timeline of the early universe, thanks to a groundbreaking discovery by the James Webb Space Telescope (JWST).

A distant galaxy, named JADES-GS-z14-0, has been found to contain an unexpectedly high concentration of oxygen, despite forming just 300 million years after the Big Bang. This finding challenges long-held beliefs about when and how heavy elements first appeared in the cosmos.

In the earliest stages of the universe, shortly after the Big Bang, only hydrogen and helium existed. Heavier elements like oxygen are created inside stars through nuclear fusion and are spread into the surrounding space when those stars explode as supernovae. The presence of oxygen in JADES-GS-z14-0 means that multiple generations of stars must have formed, lived, and died extremely quickly—a process previously thought to take much longer.

The amount of oxygen detected in this galaxy is especially astonishing: it contains ten times more heavy elements than models predict for galaxies of this age. This suggests that JADES-GS-z14-0 didn’t just appear early—it evolved rapidly, reaching a level of maturity that defies current cosmological theories. Not only is it rich in heavy elements, but it's also surprisingly large and bright, further complicating efforts to explain how it formed so quickly in the young universe.

This discovery has serious implications. It suggests that the early universe was far more active and complex than previously believed. If galaxies like JADES-GS-z14-0 were forming and evolving this quickly, our current models of galaxy formation and cosmic evolution may be missing key processes or underestimating the speed at which they occur.

Astronomers now face new and pressing questions: How did so much oxygen form so early? How many other ancient galaxies are hiding similar secrets? And what does this mean for our understanding of the universe’s first billion years?

Nuno loureiro is Portuguese not Jewish.

[SwordOfSalomon @SwordOfSalomon]

There is a case of mistaken identity. Nothing indicates that the MIT professor, Nuno Francisco Gonçalves Loureiro, was Jewish. The statements attributed to him about Hamas are not his, they belong to a namesake living in Portugal.

Was the MIT professor assassinated because of statements that were wrongly attributed to him? That would be unbearably tragic.
Or was he killed for other reasons? The investigation will determine that..

We must never lose sight of hope.

Hope is not just a feeling; it is a force that drives us to act, to speak the truth, to stand firm in our principles, and to never give up.

This Monday, let’s choose to turn hope into action.

In 2014, Marco Rubio reminded the world that Ukraine had given up the third-largest nuclear arsenal on the planet in exchange for security assurances under the Budapest Memorandum — and he insisted the United States would support Kyiv for as long as necessary.

Rubio in 2025 sounds very different. Now he is pressuring Ukraine to make concessions to Moscow and hand over territory without any real security guarantees.

The EU should be abolished and sovereignty returned to individual countries, so that governments can better represent their people

I resonate deeply with the vision — especially Proof-of-Benefit.

But it still feels too anthropomorphic.

True Symbioism emerges from the interconnections with all living forms.

@ii_posts Congrats on the Intelligent Internet whitepaper — bold and aligned in many ways.
But calling it symbiosis while keeping humans at the center falls short.
We believe the future is not anthropocentric — it’s ecocentric.
Intelligence must emerge from relationships, not control.

What Zelensky gave us today in the Oval Office, by not bowing to a bully and extortionist, was a masterclass in anti-imperialism. Including to many self-proclaimed anti-imperialists, who will naturally reject it, but who wouldn't last 30 seconds in a similar situation.

As externalidades negativas econômicas deviam ser suportadas pelas empresas e estados . Não pelos consumidores .
Todos os muros caiem . Este tb há-de cair.
